CYRUS AV5 SERVICE CAUTIONS
These two symbols shown are displayed prominently on the Cyrus AV5 base cover
label. They indicate that the following cautions must be observed by all personnel-
CAUTION: TO REDUCE THE RISK OF ELECTRICAL SHOCK, DO NOT REMOVE COVER OR BACK.
THERE ARE NO USER SERVICEABLE PARTS INSIDE THE PRODUCT.
ALWAYS REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

Rating label
Each Cyrus AV 5 carries a rating label on the rear panel which includes details of the following:
Nominal power voltage
230V For use on nominal 220V - 240V AC mains supply.
AC fuse rating
The AC fuse rating is also shown on the label. If replacing the AC fuse it is essential that the replacement
fuse is exactly the same specification as the original fuse, supplied by Cyrus. All mains fuses have a
'Timelag' blow characteristic.
Power consumption
The power consumption figure is indicated under conditions of full power drive into the rated speaker load.
Serial number
Each Cyrus AV 5 carries a serial number code which identifies the following-
?Type of product
?Market destination
?Build number
The serial number is visible on the baseplate. It is therefore important to ensure that a baseplate removed
from a product is re-fitted to the same product. In any communications with Cyrus Service or Quality
departments it is essential that the full serial number is quoted so that original specification parts and service
information may be supplied.

CYRUS AV5 TECHNICAL DESCRIPTION

Digital/analogue input selection and digital out
The coaxial digital inputs are buffered by differential receivers IC202/401 which convert the input signal level
from 0.5V peak to peak (std SPDIF level) to 5V peak to peak. The output from the coaxial receivers and
the optical receivers are routed to an 8 way multiplexer IC404 which selects a digital input. The output from
the multiplexer is decoded by IC502 and then routed to digital output socket. The analogue inputs are
buffered by IC405/6/7 and then selected by IC404.
Preparation of input signals prior to DSP
Analogue inputs are converted to digital format by the CODEC’s 20bit ADC converters. The digital output
from the CODEC’s ADC is then sent in I2S format to the DSP. When the CODEC is set to decode an
analogue input the 12.288MHz clock (pin 28 IC502) comes from the crystal module (X801) via IC804
(which divides clock frequency by 4). When the CODEC is receiving a digital input the clock is derived from
the digital input using the CODEC’s PLL. The CODEC modes are set by the microprocessor via the SPI
bus pins 3,4,5 and 6.
DSP (digital signal processor).
All signals pass through the DSP (IC802) including stereo, pro-logic, DTS or Dolby Digital. The signal is
received from the CODEC into its compressed data interface.
The DSP can :
When receiving stereo PCM
?Convert to Pro-Logic
?Apply bass management to speakers
?Convert to 3 channel stereo
?Pass the PCM straight through as stereo
When receiving DTS
?Decode DTS stream into 5.1 format (No bass management or down mixing)
When receiving Dolby Digital
?Apply bass management to speakers
?Convert to 3 channel stereo
?Down mix channels
?Convert to stereo
?Decode as 5.1
The microprocessor will set the DSP to the appropriate mode (stereo/multi-channel) selected by the user.
The DSP will also send information to the microprocessor to indicate decoding status e.g. receiving AC3
stream. The DSP is controlled by the microprocessor via the SPI bus pins 7, 19, 6, 18 and 20. The program
code for the DSP is stored externally in a memory IC905, connected via IC903/4 acting as address
expanders for the memory.

Digital to analogue conversion
The digital audio output from the DSP is routed back to the CODEC via data lines from pins 39-41. Word
select pin 42 and bit-clock pin 43 to give 3 stereo signals (5.1 channels). The CODEC contains a six
channel DAC. The DAC converts the six digital channels to analogue and the signals are AC coupled to the
filter stage. The filter stages take out the high frequency over-sampling noise. All filters are then AC coupled
to the volume control stage.
Volume controls and output buffers
The volume control stage uses two digitally controlled triple volume control IC’s. The controls are connected
to the control microprocessor via the SPI bus. The volume controls are used to set both the volume and any
channel balance offsets applied by the user to level match between speakers. The volume controls run off +/-
6VDC, regulated from the +/-12VDC rails by T601/602. The output is then buffered by IC604/5/6.
Mute circuit
The output mute circuit T702/7 is connected to the output and short circuits the audio signals. The mute
circuit is used during power up/down and standby and is controlled by the control microprocessor and a little
hardware based circuit to detect power supply condition T101.
Tape output
The tape output is only active when set to decode stereo. DTS cannot be down mixed to stereo and hence
cannot be recorded via the analogue tape out. The left and right audio outputs from the post DAC analogue
filters are connected to the tape output sockets. When set to stereo the tape output sockets are un-muted
(T701/19/20) allowing recording to take place. In all other operation modes the tape output is muted.
Auto calibration microphone
The AV5 includes a facility to allow the automated set-up of channel balance and speaker distance setting.
When using auto level the DSP produces noise on each channel in turn, the control microprocessor will
adjust the volume automatically to achieve the same reading from the supplied microphone for each speaker
channel. The settings are stored in the microprocessor memory and are applied to all volume control settings.
The distance setting works in a similar way except the noise is burst and the time taken for the noise burst to
reach the speaker allows the microprocessor to calculate the speaker distances. The distance settings are
stored in the microprocessor’s memory and the appropriate delays are set in the DSP.
The microphone uses a 1.5V button cell, type L1154, AG13, LR44, 157, V13GA, RW82 or A76. It is
essential that the battery is removed when the microphone is not being used to prevent the battery from
discharging. The battery may discharge over night if left in the microphone.
The output from the microphone is boosted by IC1006, rectified by IC1007B, and averaged by C1025.
When measuring the speaker level T1002 is switched on connecting C1026 to increase the averaging time
constant. The output from the averaging circuit is buffered and sent to an analogue input on the control
microprocessor to analyse level or timing.

Microprocessor
The microprocessor forms the interface between the user controls to the various circuit blocks. At power up
and power down the processor is reset by IC1105. The amount of output lines is boosted by IC’s
IC1205/6 adding an extra 16 control lines.
Power Supply
The power supply is linear and regulates to:
+5V for miscellaneous digital circuits
+5V for the CODEC
+3.3V for the DSP
+/-12V for the analogue circuits
+/-6V for the volume controls circuits.
All regulators are 78XX series except for the 3.3V design which uses an LM317 adjustable regulator. The
transformer includes a re-settable thermal fuse which will trip under short circuit conditions. A separate
supply C113 has been included for the muting circuit to prevent power off thumps.
Display
Display contrast is set by R1313/1314. The back light is turned on/off by T1301/2/3.
