via a RED BOX. This socket can also be used to send the preamplifier signal to an
external power amp or to additional guitar amplifiers.
LINE OUT AND POWER AMP IN:
used together the two sockets can provide an
extra loop for connecting external effect units. When used this way, LINE OUT
corresponds to the SEND socket (towards the effect unit) and POWER AMP IN to the
RETURN socket (back from the effects unit to the amplifier).
POWER AMP IN:
this allows external preamps to be connected up as alternatives to
those built into the ATS 120. Their volume can be determined using the MASTER
control. When the POWER AMP IN socket is in use, the internal preamplifiers are
automatically switched out of circuit.

FX LOOP:
the FX LOOP is specially designed for use with external effects devices. The SEND
socket is connected to the INPUT of the effects unit, and the RETURN with the
OUTPUT. The -lOdB PAD switch adjusts the sensitivity of the loop to make it
compatible with different units (OFF= 1V / ON= 300 mV, suitable for f.e.
floor-standing effects units).
TIP! The
loop can also be used to connect a second instrument or a tape for playback.
This means that when practicing an additional instrument, drum machine or a tape
recorder can be connected to the RETURN socket. Once the FX SELECT switch has
been set to the ON position, the volume can be determined using the FX-MIX control.

THE EFFECTS MATRIX ON THE ATS 120: FX-SELECT:
The
three mini switches on the FX SELECT matrix are used to allocate a connected
external effects unit to particular channels. ON indicates that the effects unit will be
activated. By using these presets, a channel change from CLEAN to LEAD (for
instance) will activate the effect without the need for extra switching procedures.
If, as described under point 12, the FX MATRIX is being used to pre-programme an
additional master volume setting, the FX SELECT switch relating to the appropriate
channel (s) must be in the ON position.

STAGEBOARD:
this 9 - p i n socket is used to connect the ATS 120 Stageboard, available as an optional
accessory. Switching facilities: CLEAN/CRUNCH/LEAD/REVERB/EFFECT.
