ACOUSTIC MASTER
2
Channel 2 EFX Loop
CH2 EFX-Send
This jack is located on the back panel. The signal is sent
dry, with no equalization.
CH2 EFX-Return
This jack is located at the back of the unit. When a signal
is fed back into the CH2 EFX-RTN jack it can go directly
into the amps or it can be combined with the internal
digital effects depending on whether the Channel 2 EFX
switch is in or out.
Do not use both the phone and XLR inputs at the same time,
signals will be highly attenuated!!
Effects Level Control (dry/wet)
This control is used to increase or decrease the amount
of internal effects used to enhance the sound from an
input source on either Channel 1 or 2. The effects level
control can be bypassed via a foot switch.
Master Volume
The master control is used to increase or decrease the
overall output of the AM100. It has no effect on the line
out signal level or the Channel 2 effects loop.
Line Out
The Line Out is post Channel 1 and 2 but pre-effects, the
gain controls and Channel 1’s equalization do affect the
output to the balanced line out, but the master volume
control does not. No effects are sent through this output
unless used prior to the amplifier (e.g. If you have your
guitar plugged directly into an effect, then plugged into
the AM100). You can use this output to directly connect
to a mixer, or another amplifier.
Digital Effects
There are 32-digital effects presets altogether in Banks A
and B, with 16-presets for each. Bank A and Bank B are
switchable via a bank select switch on the front panel of
the amp. When the switch is in the In position, an amber
LED is turned on indicating Bank A is enabled. In the Out
position, Bank B is enabled and the light goes out. This
feature can also be accessed using an optional footswitch.
Digital Effects Bank A/B
The AM100 has 2 banks consisting of 16-presets for
each. The numeric selection of each preset and its
description is located on the front panel. An Effects
Table with brief descriptions for the presets is located
near the end of the Owner’s Manual.
Footswitch
Connect a standard footswitch here to turn the internal
effects system on or off. It does not regulate the external
effects loop.
