The

lifier circuit description

e-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 single ended noise. The

X cap

reduces any

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, + the

troduction.

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.

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 rectified and smoothed by

The voltage regulators are discrete emitter followers the below as the similar.

Q305 and Q306 form a complementary Darlington NPN transistor, which is configured as an emitter follower producing +15v at it’s output. to provide bulk charge storage and to reduce the AC output impedance of the power supply.

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.

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

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 signal goes straight to the output via the mute relays version of the signal is created by

IC101

configured as unity gain non-inverting buffers.

The C30 also has a Balance XLR output stage that drives into the balanced line drivers 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 signal passes through the switch contacts in the headphone socket so when headphones are inserted the main outputs are relay muted.

Please note:

headphone sockets control contacts are faulty or damaged the unit will be permanently stuck in audio mute mode.

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.)

Multi channel input module (optional)

troduction

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.

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.

All input channel levels can be trimmed levels to allow for system balancing.

Put very simply this is an eight-channel preamplifier.

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.

When the host is communicating with the onboard micro controller PB0 will be driven low, otherwise the Data sent will be ignored.

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 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 micro controller (H8 Z1 on display board) to initialize and for the power supplies to settle.

Output driver stage

The output driver stage consists of four

OPA2134

dual channel Op-Amps

(IC400-

IC403) 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 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.

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 are very specific and should only be replaced with identical parts with the E grade high gain. for the pair, which sets the quiescent current for the entire amplifier.

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 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).

Output Capactance is as indicated in table. The specfied voltage figure w th this input votage is to be the minimum vo tage on the reservoir

capactor as shown in the diagram.

6. The transfo mer is intended to be massively ove rated so as to p ovide ve y low esistance windings for the VP24V7 and VN24V7 suppies.

This wil improve the audio qua ty of the equipment it is to be used in by allowing he flux density to be very low and he wire guage to be la ger than would otherwise be he case. The sizes given are maximum finished sizes.

There is no mert in a temp ing to reduce the size much below he maximum sizes specfied. Audio qualty wi l be improved by making he transformer as large as possble.

7. The VP46 and VP18 secondaries ae fused by T250mA Fuses. The VP24V7 and VN24V7 secondary windings are unfused.

The transfo mer must be designed so hat a short on e ther of the unfused windings wil cause the prima y fuses (2AT) to blow.

Arcam Part Number L922TX

Material Safety Specification

1. Winding Wire to be Grade 2 (130C rating) to BS 60317-4 1995

2. Mylar Polyester Insulator 130C Rated

3. Potting Compound PC3502 E135297(M)

Mechanical Specification

1. Middle of transformer to be potted (as shown).

2. Primary windings connect to 6 way MOLEX connector 39-01-2065. Secondary

44476-3112. MOLEX connectors have pin numbers indicated on them.

3. Primary wires are enclosed in a common sleeve. Secondary wires are enclosed in a common sleeve. Use PVC sleeving.

4. All wire lengths in mm. Lengths are +5.0, -0

5. Please adhere rubber insulating pad to bottom of transformer as shown.

Electrical Specification

1. Transformer to have dual 100V primaries to allow parallel operation for 100V input.

2. Transformer input voltage range

100V -15% +15% (85V to 115Vrms)

3. Transformer to have 4 secondary windings as show in the adjacent drawing.

4. Loaded DC voltages specified at 85V AC in (with transformer primaries in parallel)

5. Each secondary winding to have a full wave (4diode) bridge to produce a single DC rail. (AS shown in diagram)

Output Capacitance is as indicated in table.

The specified voltage figure with this input voltage is to be the minimum voltage on the reservoir capacitor as shown in the diagram.

6. The transformer is intended to be massively overrated so as to provide very low resistance windings for the VP24V7 and VN24V7 supplies.

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.

There is no merit in attempting to reduce the size much below the maximum sizes specified. Audio quality will be improved by making the transformer as large as possible.

7. The VP46 and VP18 secondaries are fused by T250mA Fuses. The VP24V7 and VN24V7 secondary windings are unfused.

The transformer must be designed so that a short on either of the unfused windings will cause the primary fuses (2AT) to blow.
