MASTER VO LUME
This control is used to increase or decrease the acoustic output of the AM150. It has no effect on
the line out signal level or the Channel 2 effects send.
DIGITAL EFFECTS System
There are 32 digital effects presets altogether divided into BANK A and BANK B with 16 pre-
sets in each. The banks are selectable via a pushbutton on the front panel of the amp near the
POWER switch. When the button is in, BANK A is selected and the amber LED nearby illumi-
nates. In the out position, Bank B is enabled and the light goes out. To select a specific effect,
use the PRESETS control. A numeric selection of each preset and its description is located on
the front panel of the AM150. Additionally an Effects Table with brief descriptions for the pre-
sets is located near the end of this Owner's Manual. A FOOTSWITCH jack on the back panel
accepts a standard footswitch, eg our model TFS-1, to turn the effects system on and off.
Mono BALanced LINE OUT (XLR)
This line out is post channel 1 and 2 but pre-effects and pre-master volume. In other words
the channel gain controls and Channel 1's tone controls do affect the output signal, but the
effects master and master volume do not. Also, no external effects connected to channel 2's
efx. are present on the signal, i.e. it is "dry." You would use this output to directly connect
the AM150 to a mixer in any situation where effects are not desired on the line out signal.
LEFT (MONO) & RIGHT Balanced POST EFX LINE OUT Jacks (1/4-inch)
These are post-effects (i.e. wet) and would be used for delivering signal to a mixer or amplifi-
er when effects are desired on the line out signal. Using Balanced or unbalanced shielded
cables, connect one or both of these jacks to the input(s) on your mixer. If there is only a sin-
gle, mono input on the mixer, use the LEFT/MONO jack.
