C30 preamplifier circuit description.
Introduction
The C30 pre-amplifier uses pre-amp input
switching/control and display boards that are
very similar in design to the boards used in
both the Diva A85/A90 and Fmj A32
integrated amplifiers and as such you may
already be familiar with the layout and
topologies of these boards. The C30 boasts a
very much over-engineered power supply and
output stage that is designed to bring the very
best out of the existing Pre-amp input
switching board.
The main PCB L958AY also contains output
buffers for the unbalanced outputs to drive
long cables and balanced line drivers. A
headphone amplifier is included to drive low
impedance headphones down to 32 Ohm.
For description of the pre-amplifier switching
and control board see the section...
Power supply.
The mains input comes in via SKT1. Two Y
caps return common mode noise to the
chassis ground and an X cap reduces any
single ended noise. The 1M5 resistor
following this is in place to discharge the
capacitors when the unit is turned off.
The mains selector switch, which follows the
resistor, changes the configuration of the
transformer windings from series for 230V to
parallel for 115V. Tx1 is a standby
transformer it powers the microcontroller at all
times so that the unit can be put into and out
of standby. To reduce voltage losses after
this transformer, low forward drop diodes are
used. A low drop out regulator follows to
create the 4.5v(D) supply; this supply powers
the micro and digital circuits.
The primary of the Toroid supply transformer
Tx2 is connected to CON3 and the power to
this is switched on and off by the relay RLY1.
The transformer has a number of secondary
outputs and we use separate taps and bridge
rectifiers networks followed by bulk
capacitors to smooth the ripple. The voltages
generated are +24V and -24V for the main
analogue supplies, +46V for the HT supply to
the VFD, and +18V, which is used to power
the trigger output. The smoothed +/- 24V
then goes through regulators REG 2 and
REG 5 to create +/- 18V this is passed the
pre-amplifier PCB via CON4. Another set of
regulators REG 3 and REG 6 follow taking
the 18V and creating a +/-15V supply that is
available for add on modules such as the 7.1
channel input board. A 5v supply is derived
via regulator REG 4 from the 18V to run the
headphone amplifier.
Mains detect.
A mains present detector runs from the
standby transformer, this detects the loss of
mains using a peak hold circuit based around
D7/TR1/DZ1 and TR2. If the power is lost this
piece of circuitry sends a flag to the
microcontroller so it can mute the outputs
and shut down the unit. See Fig 1 for notes
on protection modes.
12v trigger and RC5 receiver.
The trigger output on SKT2 is driven through
TR4 to provide a current limited supply at
around 13V.
IC1 A and B are used to demodulate
incoming RC5 from socket SKT2. IC1A is a
band-pass filter centred on 36KHz. This is
followed by a peak detector circuit that
demodulates the incoming signal.

Introduction.
Input switching
The pre-amp stage is a high-performance,
DC coupled design with microprocessor
control of input select, two independent tape
loops, electronic volume control and tone
bypass.
Each of the inputs has a pair of diodes to the
+/- 15v rails to prevent static spikes from
causing damage to the CMOS multiplexors.
In addition, there is a simple resistorcapacitor filter with a corner frequency of
approximately 340kHz to remove any
unwanted high frequency interference from
the signal. This uses high quality WIMA
polypropylene capacitors for the best
possible performance.
It features a discrete power supply and lownoise linear circuitry to obtain exceptionally
low distortion and noise performance results.
Power supply stage
The secondary transformer output windings
from the main toroid transformer are
connected to SK300. The A.C voltage is
rectified and smoothed by D300, D301, D306,
D307 and C300, C301. The unregulated
voltage should be around +/- 27 V obviously
this is dependent on the A.C level at the
mains inlet socket; F300 and F301 are the
secondary A.C s.m fuses these are rated at
2A.
The voltage regulators are discrete emitter
followers the +15 voltage stage is described
below as the –15 v stage is effectively very
similar.
Q300 and R300 act as a constant current
source, supplying around 7mA into D310.
C302 and C314 reduce ripple and broadband
noise on the zener diode. Q305 and Q306
form a complementary Darlington NPN
transistor, which is configured as an emitter
follower producing +15v at it’s output. C303 is
to provide bulk charge storage and to reduce
the AC output impedance of the power
supply.
D302 prevents reverse bias of the supply
during power down.
Z301 is a conventional LM317 type circuit to
regulate the +15v rail down to +5v for the
tone and volume control circuits.
Z104 (left) and Z105 (right) are the main
input multiplexers, which are configured in a
“virtual earth” unity gain arrangement with
Z115 and Z116. This is an inverting circuit
topology and the phase is corrected by the
inverting volume control.
Z115B (left) and Z116B (right) are the
integrating servos, which remove any D.C
coefficient from the Analogue input switching
stages before the signal is passed onto the
following stages, R180 and C147 (left) form a
filter to remove any broadband noise from the
servo output and to improve the speed
response.
Z100 – Z103 are the Tape output selectors
these are non-inverting and the outputs are
again buffered by Z9 a/b and Z10 a/b before
arriving at the two tape loop outputs.
Z106 is configured as a double pole
changeover switch and is used to select the
tone controls or direct by pass mode. (See
below for more information).
Tone controls
The tone control stage is non-inverting and
uses a gyrating bell filter for the Bass and a
simple shelving filter for the high frequencies,
the left channel only will be described.
The input is attenuated by –6dB and biased
to a voltage of +2.5v D.C by C111, R113,
R112, R110, R111 and C110. This is so the
signals fall within the 0 – 5v D.C required by
the digital potentiometer Z108.
Z111B and its associated components form
an active equivalent of a series resonant LCR
circuit. This has an impedance minimum 5.4k
at around 80.
The digital pots Z108D and Z108A control the
bass
and
treble
respectively,
this
accomplished by moving the wiper connected
to
the
frequency-sensitive
impedance
between to non inverting and inverting
terminals of Z112A, effectively changing the
ratio of feedback boost and feed forward
attenuation of the circuit at the desired
frequencies, thus providing a EQ gain control
that is on a logarithmic scale, with the use of
a linear pot.
Z112B provides the 6dB of gain necessary to
bring the nominal level of signal back to unity
C116 and C117 remove the 2.5VDC offset
from the output to prevent click and bangs
when the tone control are activated.
Z108 is controlled by a simple 3-wire serial
interface from the microprocessor. Each of
the digital lines has it’s own ground return
these are terminated at the GND pin of the
chip to minimize any electromagnetic
interference.
Audio output stages.
The Audio output stage contains the
buffered, un-buffered and balanced outputs
as well as the headphone driver.
The audio signal from the preamp PCB
enters the board on CON100 and the direct
signal goes straight to the output via the mute
relays RlY100A and RLY101B. A buffered
version of the signal is created by IC100 and
IC101.
IC100 and IC101 are op-amps
configured as unity gain non-inverting
buffers.
The C30 also has a Balance XLR output
stage that drives into the balanced line
drivers IC103 and IC104. These line divers
create a transformer-less balanced output.
Headphone Output.
The selected audio output signal is driven
into the headphone driver IC102; this signal
then passes through CON101 and CON102
to the headphone socket SKT101. The mute
signal passes through the switch contacts in
the headphone socket so when headphones
are inserted the main outputs are relay
muted.
Volume control
Z107 is a VSDVC electronic volume control
IC. It works in conjunction with external opamp Z117a/b by varying the feed-forward and
feedback resistors in an inverting gain
configuration, the volume control is driven by
3-wire data from the H8 micro on the display
board – if the control receives no data it will
remain in Audio mute mode.
Relay RLY100 shunts the output of the Opamps to ground at switch on – power down
and when switching between inputs.
Please note: this means that if the
headphone sockets control contacts are
faulty or damaged the unit will be
permanently stuck in audio mute mode.
RC5 remote code assignment change.
The C30 has the ability to switch between
RC5 system code 16* and 19, we can
achieve this by pressing and holding the
Phono/Aux – CD and AV – DVD buttons
simultaneously the display will show.
RC5 System Code
16*
We can toggle the system code using the
rotary encoder.
Display board
The display board is very similar in design to
the board that has been used for many years
in the A85 family of products inc FMJ A32
and as such those of you familiar with these
products will know there way around this
board, a full description follows.
The power supply rails for the display board
are derived from the main board we should
expect to see the below supplies in place (Fig
2.)

Please note: the H8 micro is very critical of
the +5v supply and as such the unit may
crash or fail to power up during use if the +5v
supply drops below 4.5v.
H8 Microprocessor
The H8 micro at location Z1 is preprogrammed by Arcam using a flashprogramming module and cannot be
reprogrammed in the field unless you have
access to the appropriate hardware and
software.
The H8 forms the heart of the C30 and takes
on all major control functions including.
1. Control of the input switching.
2. Controls the action of the volume cont.
3. Monitors protection status and mute lines
A85/A90/A32 only.
4. Sends display information to the VFD.
5. Receives and decodes RC5 data.
6. Receives data from rear panel remote
input.
7. Stores setting information via 24C02 Eprom.
At initial power up the H8 micro is reset by Z2
a DS1233 econo reset package.
The input switching information is driven out
to the Pre-amp card via the 9 select lines that
appear on Pins 14 – 22 of SK3.
The Volume control and tone control circuits
are driven from the SDATA – SLOAD and
SCLK data lines from SK3.
The Mute status line has control over the
pre-amp output relay at location RLY100; the
mute is triggered during power up/down and
between input selections and under Mute
commands.
Within the C30 the DC prot, Therm, VI prot
and SP1/SP2 control lines are all connected
to Digital ground on the main board of the
pre-amp as these are not required within this
product.
The H8 drives the VFD via 4 Data lines that
can be seen on R64 – R67 as DISPDAT,
DISPCLK, DISPBLK, DISPLAT these drive
directly into the VFD.
Remote Data can be received by the C30 via
the 3.5 mm Phono jack on the rear of the
Pre-amp and the previously described
remote demodulator on the main board this
demodulated RC5 arrives on the display
board via Pin 3 of SK1 and goes into a
common IR input pin of the H8 micro (pin 87)
this pin is also used to pick the RC5 code up
from the Display onboard remote receiver.
At power up the H8 reads all previously
stored and last settings used by the amplifier
from the e-eprom at location IC5 these will
include the last input used and tape settings
also tone control and input level settings, any
changes to the set-up of the amplifier are
sent to the e-eprom for future recall, at power
down the H8 downloads it’s settings to the eeprom.
All indication LED’s are driven directly from
the H8 micro, these LED’s are tagged onto
the +5v rail via 10k current limiting resistors
Q1 and Q2 form a toggle between Green and
Red for the standby/power LED.
The volume control is driven from a Rotary
encoder at location SW18 the toggle lines
from the encoder arrive at the H8 as control
lines Phase A and Phase B on Pins 93 and
94.
Multi channel input module (optional)
Introduction
used for communication these are seen on
the circuit diagram as PB0, receive from
ExpBrd and Transmit to ExpBrd.
The multi input module an optional expansion
board that allows the existing Amp/Pre-amp
to become part of a surround system when
driven by a DVD/SACD player with Analogue
surround outputs.
When the host is communicating with the
onboard micro controller PB0 will be driven
low, otherwise the Data sent will be ignored.
The board has two sets of 7.1 input (8
channels) these are labelled as MCH1 and
MCH2 and accept Left, Right, Centre, Left
surround, Right surround, Left Back, Right
back audio Information.
The input allow for the signal routing of the
eight channels from either of the inputs these
are MCH1 and MCH2, select lines S1-S2-S3
are used to select each bank of inputs this
inputs stage utilizes 6 x 74HCT4053
multiplexers you will notice that IC204 and
IC205 only utilize the S1 and S2 select
channels as this input switch only deals with
two channels (Back left and Back right).
All input channel levels can be trimmed levels
to allow for system balancing.
Put very simply this is an eight-channel
preamplifier.
Input switching
Please note: The software will only allow one
set of inputs to be selected at any one time.
Power supply
The board is powered from the +/- 15v supply
on the existing pre-amp board on board
regulators REG100 and REG101 regulate
these rails down to –5v and +5v respectively.
The digital sections of the circuit are powered
by a single +5v rail this is isolated from the
main 5v rail via inductor L100.
Capacitors C100, C101 and C105, C107 act
as bulk charge stores to prevent current
surges from affecting the main pre-amp stage
power supply stages.
Micro Processor
The micro controller operates from a 4 Mhz
crystal and is in control of all of the board’s
function via its input/output ports.
The micro controller is reset on power up via
R/C network R101 and C120. The micro
controller stays in reset condition for
approximately 500ms this allows the host
micro controller (H8 Z1 on display board) to
initialize and for the power supplies to settle.
The Host micro communicates with the
onboard micro via CON 101. Three lines are
The outputs of the input multiplexers drive
into a group of 8 line drive Op-Amps
(IC300-IC307) these are configured two pole
integrating D.C servo before reaching the
Volume control stages.
Volume control
Volume control is performed by two channel
Burr-Brown PGA2310 volume control chips.
The gain is under micro control with steps of
0.5dB.
All volume control chips share Data, Clock
and Mute control but have Chip select lines
that are grouped in the following way Front
Right, Front Left, Centre and Sub share the
same select line, and the remaining channels
share a chip select line (Surround right and
Left, Back right and Left). The volume of
each channel can be controlled individually
“trimmed”.
If a loud clicking is heard on a individual
channel whilst adjusting the volume it is
probably the input stage that is at fault and
not the volume control chip itself, the input
stage should prevent D.C levels form
entering the volume control.
Output driver stage
The output driver stage consists of four
OPA2134 dual channel Op-Amps (IC400IC403) each output for instance Front left
channel takes one channel of the op-amp.
The front left and front right channels are
driven down into the Pre-amp board via Pins
1 and 2 of connector Con400 and is fed into
the input switches of the Pre-amp boards
multiplex on Pin 9 from this point the signal is
dealt with as a normal signal input into the
Pre-amp.
Please note: the left and right signals are
seen on the L937 pre-amp card circuit
diagrams as module left and module right.
The Remaining channels are rail clamped to
remove any over-voltage spikes from the rails
and to prevent damage to ancillary equipment
using diode packages D400 – D405.
Each output has a mute relay that when
engaged shunts the output to ground at
power up and power down preventing any
spurious D.C levels from leaving the card.

Phono stage
The Phono board is a simple single stage
RIAA amplifier. It consists of two channels of
high gain amplification, and switching
between moving magnet (MM) and moving
coil (MC) settings.
PSU:
The unit derives its ±15V regulated rails from
the unit it is fitted into with only local
decoupling capacitors on board.
Interface:
The unit connects to the host unit via a 8 way
connector:
Amplifier:
The left channel has designators beginning
with 100, and the right with 200. For the
purposes of this description the left channel
will be described, as the right channel the
same in all respects.
The amplifier is a small signal class A voltage
feedback amplifier with switchable gain. The
input consists of an actively loaded
differential pair of very low noise PNP
transistors (TR106, 107). These transistors
are very specific and should only be replaced
with identical parts with the E grade high
gain. TR100 & TR101 form a current source
for the pair, which sets the quiescent current
for the entire amplifier. The active load
consists of TR110 & TR111, which forms part
of a differential current mirror with TR112,
113 & 114. This differential stage also has an
active load (TR102 & TR103) to keep gain to
a maximum.
Both of these differential stages are designed
to have as much gain as possible to enable
the single stage design. The RIAA response
is achieved in the feedback network:
C101,110,111,112,119,120,&R115,112.
C115 is used to correct between MM & MC
gains as the amplifier is non-inverting.
SW100 switches between MM & MC. Two
poles of the switch change between the
different loading required for each type of
cartridge: R108 & C109 for MM, and added
inparallel for MC R104 & C108. The other
two poles change the feedback resistor value
to alter the gain. MM: R105 and in parallel
for MC R123.
The DC offset is controlled by a non-inverting
servo built around IC100. The amount of
servo current is different for each gain setting
via R111 (MM) & R124 (MC) so that the low
frequency high pass point remains the same
for both settings. However the high pass
point for the circuit is set by C113. This gives
a warp filter, stops DC startup thumps from
upsetting DC coupled circuitry and an
approximation of the RIAA/IEC curve (-2dB
@ 20Hz).
The output is class A buffered by a dual
mirror follower (TR104, 105, 108, 109). The
quiescent current is set up by D100 and
R118, 119.
Closed loop stability is achieved with C116,
117 giving symmetrical slewing capability.

This will improve the audio quality of the equipment it is to be used in by allowing the flux density
to be very low and the wire guage to be larger than would otherwise be the case. The sizes given
are maximum finished sizes.
