Y
Diagram 1 shows the ratio of the input level (X axis) and output level (Y axis). The upper trace was record-
ed at maximum compression and the lower trace shows linear gain. The diagram also shows how the
limiter prevents the output level from rising above 0 dBu.
LEVEL: This rotary control sets the volume level of the input channel.
The MASTER OUTPUT controls affect the main output (LINE OUTPUT) only and do not affect the signal
at the REC OUT jacks.
BASS: This rotary control provides approx. 10 dB of shelving low-frequency cut or boost at 100 Hz.
TREBLE: This rotary control provides approx. 10 dB of shelving high-frequency cut or boost at 10 kHz.
dB
OUTPUT LEVEL: This rotary control sets the volume level of the LINE OUTPUT.
POWER: Switches power to the mixer on (position "I") and off (position "0").
The green ON LED next to the POWER switch will illuminate to indicate the mixer is ON.
Refer to Fig. 6.
EXPANSION IN/OUT: These two 8-pin mini DIN sockets (also known as Hosiden or S-VHS sockets) let
you daisy-chain up to 10 AS 4+3 automatic mixers. For this purpose you will need one or more option-
al IC AS8 connecting cables from AKG. You can set the CONTROL MODE functions on each mixer in
the chain individually and the output parameters for all mixers on the last mixer in the chain only.
Refer to Fig. 8.
DUCKING MASTER: This DIP switch activates and deactivates the ducking function.
ON: As long as the MIC 1 microphone channel is active, the level of all other input channels (MIC 2 to
4 and LINE 1 to 3) on this and any other mixers that may be connected to it will be reduced.
OFF: The status of the MIC 1 channel does not affect the other channels.
GROUND CONNECT: As long as this switch is in the ON position (down) the metal case of the mixer is
electrically connected to ground and the shield connections of all input and output sockets. We
recommend that you always leave GROUND CONNECT in the ON position. However, if you connect
the mixer to other equipment that is grounded, too you may end up with a ground loop that
causes hum. You can eliminate the ground loop (and the hum) by setting GROUND CONNECT to OFF
(up).
