8•BUS EQ FAILURES
Model: 8*Bus, all
Symptom: EQ failures, dead, noisy, intermittent, etc..., channel functions normally
when EQ and HPF are bypassed.
Cause: Faulty EQ module or cold solder joints on EQ module. May also be due
to a bad connection or component in the circuitry supporting the EQ
module, but more often than not it’s the module itself.
Fix: First, inspect the solder joints on the EQ daughter board and supporting
components. If problem persists, replace the EQ daughter board, part
#055-016-00.
Notes: EQ daughter board uses all surface mount components, much easier to
replace than repair.

8•BUS METER FLICKER / CROSSTALK
Model: 8*bus, all.
Symptom: When a level is displayed on any of the bar graph meters, other meters
flicker or indicate a small level with no signal present on their associated
bus. May be intermittent.
Cause: Bad digital ground connection. Usually in the 5V cable or its connectors.
Solution: Remove the molex connectors, solder the 5V cable’s leads directly to the
PCB on both ends, and jump pins 1 and 3 of the 5 volt cable together on
the master PCB. (This is the 3 conductor cable that runs from the power
distribution PCB to the output (master) PCB.)
Notes: 5V cable part # 040-025-00. Global problems with the solo, mute, and
metering functions can also be related to this cable.

METER BRIDGE ANALOG METER REPLACEMENT
1. Remove right end cap
IMPORTANT: Do Not remove left end cap, removing the left end cap can cause
alignment problems when re-assembling.
2. remove source select button.
3. Carefully slide out face plate.
4. Remove jumpers connecting analog meter PCB to bar graph PCB.
5. Remove rubber ring from cable.
6. Push ribbon cable through back of meter bridge housing.
7. Carefully slide out analog meter PCB.
Before installing the new analog meter PCB, affix the provided white plastic insulator to
back of the meter bridge housing so it will keep the meter terminals from shorting. Also,
apply the black foam rubber tape to the front-inside edge of the end cap so that it
presses against both the PCB and the face plate when re-assembled.
Installation is the reverse of removal except for calibration.
Mechanical Calibration (-∞dB)
Before putting on face plate, stand meter bridge in an upright position as it would be in
use and adjust each meters mechanical zero if necessary.
Electronic Calibration
The meters sensitivity trim pots are set at the factory and should not require adjustment.
However, if needed, they can be adjusted as follows:
1. Install meter bridge onto mixer with its face plate removed.
2. Check mechanical calibration.
3. Run a +4dB, 1kHz signal to the main outs, measure it with an audio analyzer or DMM
(+4dBu=1.23 VAC RMS), Do not go by the bar graphs!
4. Adjust trim pots so that meters read 0dB.

Funny little things the 8•Bus does and what causes them.
Some miscellaneous failure modes not covered in previous Mixer Fixer notes.
Channel overload light comes on with no signal, channel passes signal normally except
for distortion with high level signals. May only happen after mixer heats up.
1. Check R_74 (pull down resistor for op-amp following fader) it probably only has 1 leg
inserted, or it may have a cap stuffed in its place.
2. If R_74 is not properly installed another 15K resistor can be installed from the back of
the PCB.
Subgroup 4 goes out when a plug is inserted into tape out 4, 12, or 20.
-Solder bridge on tape out pcb.
-Check the vias adjacent to the ribbon connectors on the tape out PCB.
Noisy Mic/Line preamp
-More often than not caused by the 4148 calmping diodes.
Mute switch pops on console with meter bridge installed.
-If the pop goes away when the meter bridge is disconnected the problem is a solder
bridge on the bargraph meter PCB causing DC to leak into the channel via the meter
feed (same path as the direct out).

32•8 NOT POWERING UP CORRECTLY
Model: 8•Bus Power Supply and console, usually 32•8 with meter bridge.
Serial #: Power Supply serial G27894 - G29655.
Symptom: All overload lights come on and stay on upon power up. If the Power
Supply is switched off for a second then back on the console functions
normally.
Cause: New revision Power Supply’s current limiting is more sensitive. The inrush
of current drawn by a cold power up can cause it to latch the +18V rail
at or near ground.
Solution: Remove R39 and R44.
Notes: R34, R44 = 6.81k, changed to 10K on units with serial above G29655.

8•BUS REMOTE TALKBACK MODIFICATION
The diagram below illustrates the easiest way to add remote controllable relay to the
studio/phones talkback switch without interfering with the original switch. This
modification can be performed entirely from the back of the master PCB and does not
require removing the PCB.
Notes: Simply paralleling a switch across the back of the existing switch will not
work because the existing switch holds the T/B-to-studio/phones input at
ground until pressed.
Page 31
The console’s +12VDC lamp supply can be used to drive the relay.
