Introduction
The purpose of this manual is to support skilled technicians in repairing the Gold
Channel.
The manual begins witha Quick Trouble Shooting table. Here, hints, advices and
possible problems are described.
If the problem is more serious, the next step is to use the Built-in Test Program.
With this program the problem can often be narrowed down to a specific section,
channel or even component.
The next section consist of disassembly and exchange procedures. Please be aware
of warranty rights before disassembling. Refer to the warranty card.
The Block diagram gives a quick overview of the signal flow.
Circuit description is a brief description of the circuits on the different boards.
LED error codes and Jumper settings are described on page 13.
Software Changes describes the changes from older software versions to newer
versions.
Appendix contains Schematics, Part lists, PCB Layouts and service notes.
The schematics start with a main sheet, where sub sheets are shown as blocks.
Even sub sheets might have sub sheets. In the schematics some connections have
label names to help the reader. If a label name is framed, it means that it is
"connected" to another sheet. Label names followed by the symbol "*" mean that
the signal is active low, i.e. RESET*: the reset function takes place when the signal
is low.
Part lists contain a column called TCcode/ Item no. Use this code/no. when
ordering spare parts. If the field is empty; it means the component cannot be
ordered separately.
The coordinates in the column Pos. refer to the PCB layout page. The column
named Page refers to page no. in the schematics. In column comments a short
explanation of the function is stated. For some components, alternative types are
mentioned.
Some PCB layouts are made as gatefolds (fold-out page).
Finally appendix contains a list for mechanical parts.
This service manual does not contain schematics for the power supply module,
because any attempt to repair the power supply module must be completed with
some safety tests such as high voltage and EMC tests. Hence, it is strongly
recommended that the entire power supply module is replaced in case of
malfunction.

Built-in Test Program
The Gold Channel has a Built-in Test Program. To run the program; Press the PROGRAM button while powering on. Select RUN TEST PROGRAM and press ENTER. Follow the
instructions on the display. To leave the Built-in Test Program; turn off the power.
Gold Channel Built-in-Test Program v3.09 has following tests:
TEST Function / Comments
Keys Tests the keys at the front panel one by one. If a key hasn't been pushed a warning message will appear when leaving the test
IN knobs Tests the function of the Input potentiometers
PARAM+VALUE Tests the steps of the encoders. Each stepis counted at the display, if not; check soldering at the encoder ot the front connector.
LED's Tests the LED's at the front panel one by one. If no light; check soldering at the LED and at the flat cables between the front boards.
Display Tests all dots in the display. If any missing; replace the display. If the backlight is bad or blinking; check the soldering on the display itself, especially the two
connections going to the upper of the display.
Analog I/O A sine wave is generated on both analog outputs. When connected to one of the analog inputs the display reads OK if the level is correct. In this way a
problem might be narrowed down to a specific input or output. The levels can be checked at 60dB, 40dB, 20dB and 0dB PAD.
Note: On the display it says "Meter must show -12dB.." However, if the meter only shows-16dB, it is also OK.
Note: In case of defective IC35, IC36, IC41 they should be replaced with type MC33079
Digital I/O A digital signal is generated on the digital output. When connected to the digital input the display reads OK if the level is correct.
Midi I/O A midi signal is generated on output. When connected to the input the display reads OK if the signal is correct. The midi signal from input is sent on to MIDI
THRU. If not OK; trywith another midi cable or check soldering and components in the midi circuit.
Pedal socket Tests the status on the EXTERNAL CONTROL IN. When no jack plug is inserted the result must read "Not OK". If a jack plug is inserted and the tip of the
plug is connected to ground, the result must read OK.
PCMCIA Tests whether programming, reading or deleting are OK. NOTE: All data on PCMCIA card will be destroyed.
Battery Tests the DC voltage at the Back up battery. If low; check battery voltage with a multimeter and check also the standby current by measuring the voltage
across R27; max. 20mV (numerical value). If the voltage is higher; replace IC4. When replacing battery, please refer to section "exchange of battery"
System. Tests the MPU, DSP, DARC, SOUND RAM to some extent.

Circuit Description
The Gold Channel consist of a front, a digital, an analog and a power supply section. Here is a brief description of the sections:
Front section consist of three boards and a display, all placed in the front profile. The
big board has two matrix circuits; one for LED's and one for keys. The two encoders
are scanned by IC20 and the two pots are connected directly to the MPU on the main
board. The EEPROM contains the serial no.
The small boards are for LED's and key switches.
Digital section is placed mainly in the middle and in the left side of the main board.
This section contains the Reset, MPU, SRAM, DSP, DARC, Sound RAM, FLASH,
Interfaces and PLL circuit.
Reset controls the MPU and the DA.
The Software for MPU is loaded into the FLASH. The MPU controls DSP, SRAM, Jeida,
Front, MIDI, External Control In and analog gain settings.
The major task for the DSP is to "calculate" sound. It also generates the 80MHz clock for
the DARC chip.
The DARC chip controls the sound data to/from; DSP, Sound RAM, digital in/outputs,
Word clock Input and AD/DA converters.
Interface for MIDI and External Control In consist almost of discrete components.
The interface for the front has an integrator, which converts a 3.3kHz square wave to a
negative DC voltage for the display contrast. By changing the duty cycle of the square
wave the DC voltage and thereby contrast will also change. An attenuator allows the MPU
to measure the contrast voltage.
The PLL circuit (placed on a separate board) makes a very stable frequency at 256 x sample
rate, this frequency is divided down to 64 x sample rate and to 1 x sample rate by the DARC.
The PLL has its own power regulation.
Analog section is placed mainly on the right side of the main board.
The analog input is balanced, thus pin 3 should be connected to pin 1 when used with
unbalanced equipment.
Input levels are controlled by digital potentiometers. These potentiometers are located in a
single chip, which controls both the two analog input levels and the two analog output levels.
The A/D converter is a 24bit converter . The A/D and D/A converters have also a separate
power regulation.
The D/A converter is also 24bit. A DC voltage is applied to the left & right signal output at
the converter.
After the D/A comes a 2nd order filter, then the output level and then a 1st order filter.
An electronic balanced circuit perform the output stage. Again XLR pin 3 should be
connected to pin 1 when used with unbalanced equipment.
The Mic. amp is placed on a separate board. This board comes in two versions; P12905-3and
P12905-5. If the board version is P12905-3,make sure it is updated according to the service
notes in appendix.
Power supply section consist of a separate Power Supply Module and some regulation
circuits on the main board.
One regulation circuit has an electronic switch for the +/-15V. The electronic switch for the
+5V is mounted inside the Power Supply Module. The switches are controlled by the Stand
By circuit. The Stand By circuit is supplied from a separate power wire from the Power Supply
Module.
Phantom power is fed to the Mic. amp board. Here it can be switched on or off.
This service manual does not contain schematics for the Power Supply Module, because any
attempt to repair the module must be completed with some safety tests such as high voltage
and EMC test. Hence it is strongly recommended that the entire Power Supply Module is
replaced in case of malfunction.
Note:The Power Supply module for the Gold Channel is unique due to the phantom power.
