The GOA7C's CROSSFADER is based around an electronic VCA circuit that greatly extends its
life and additionally has the great advantage of being removable and replaceable by yourself. To do so,
just follow these instructions:
1 - Remove the screws of the plate that hold the CROSSFADER.
2 - Remove the set from the mixer.
3 - Detach the multipin connector.
4 - Replace the whole set or remove the screws that tie the potentiometer.
5 - Tie the new potentiometer and the associated printed circuit and multipin connector to the
plate.
6 - Attach the multipin connector.
7 - Place the set on the mixer.
8 - Fix the screws of the plate.

4.5. Talkover

This device automatically reduces the signal level just at the first voice "hit" of the speaker on the
microphone plugged to the channel which is assigned to the Talkover. When the speaker stops talking
the music level comes up to the initial level. The talkover is enabled through the ON (31) switch, and has
efficiency, LEVEL (34), main signal level attenuation (between 0 and 30 dB) and recovery time,
RELEASE (33), the time necessary for a progressive come back to the original level (between 0,1 and 3
sec).
The channel(s) assignable to Talkover are internally selectable, see configuration diagram. The
GOA7C talkover is factory preset at channel 1.

4.6. Outputs

The GOA7C mixer has two independent outputs, MASTER A and MASTER B. Each one has its
own volume control, with a sliding fader for MASTER A (28), and a rotary one for the MASTER B (21).
Both outputs have a dedicated balance control BAL (25-20).
You must be careful when setting up the general output level of the mixer. The "clip" display of
the connected power amplifiers must never remain permanently lit, but do it only occasionally by
following the rhythm of the bass signals that are being played.
The GOA7C mixing unit is factory adjusted at 0dBV/1V, although this output can be internally
modified to +6dBV/2V. See configuration diagram.
The MASTER A output (45-46) is balanced or symmetrical, and the pin-out of the connector is as
follows:
Hot or direct signal
Cold or inverted signal
Ground
The balanced circuit simulates an output transformer, so if you wish to use MASTER A in non-
balanced mode, you should short circuit the unused pin to ground. Otherwise, the signal will not have an
appropriate level and quality.
The MASTER B output (47) is non-balanced or asymmetrical.
The GOA7C has two recording outputs: REC1 (44), which is pre-talkover (no signals which
activate the talkover are passed to this output, so no attenuation occurs) and REC2 (43), which is
influenced by the talkover.
Finally, a MONO (24) switch that converts an stereo signal into a monophonic one or sends one
side to both channels. This switch affects the outputs MASTER A, MASTER B, and REC2.
