able to stop all of it. Reduce volume, reduce the LOW,
MID or HIGH EQ control setting or move the guitar
farther away from amplifier to defeat the feedback.
Clip LED
This feature can be used to gauge input level to avoid
audible clipping. If it begins flashing you have turned up the
GAIN, one or more of the EQ controls and/or the instrument
to the point where the amplifier is running out of power
headroom. Do not turn up further or distortion can occur.
Channel 2 (General Purpose)
Inputs
This channel’s ¼-inch INPUT jack accepts line level
signals, e.g. from a **CD player, a tape deck or a mixer.
Alternatively it can accept any guitar with active pickups
(i.e. with a built-in preamp), or any keyboard instrument.
It is balanced Tip (+), Ring (-), Sleeve, however it also
accepts unbalanced cables. For best results and to
reduce noise, it is advised that you use balanced cables
wherever possible. The 3-pin XLR INPUT connector
accepts any low-impedance dynamic microphone.
Alternatively it can be used as a balanced line-level
input, perhaps from a mixer’s monitor or auxiliary output.
**To connect a stereo source to the ¼-inch input of Channel 2’s
input, use an appropriate adapter, which terminates in a male ¼-
inch stereo plug (e.g. dual female RCA to ¼-inch male stereo).
Do not use both the ¼-inch and XLR inputs on Channel 2 at the
same time, signals will be highly attenuated!!
EFX Loop - General
Channel 2 can be sent to the AM150’s internal digital
effects system via the EFFECTS Defeat /Active
pushbutton (active in the down position). However this
channel can also be connected to an external effects unit
and/or a graphic equalizer (Channel 2 is not affected by
Channel 1’s EQ or Notch filter hence some equalization
may be desired for certain instruments or other signal
sources). Internal effects and loop-connected effects, EQ,
etc. can be run at the same time on this channel (only).
EFX Send
This unbalanced ¼-inch output is located on the back
panel. Connect it to the input of the external effects unit
or EQ with a standard unbalanced shielded patch cable.
EFX Return
This unbalanced ¼-inch input is also located on the back
panel. Connect it to the output of the external effects unit
or EQ with a standard unbalanced shielded patch cable.
EFFECTS MASTER Control (dry/wet) and EFX
FOOTSWITCH jack
The control increases or decreases the intensity of
internal effects (note, it does not regulate the intensity
of any external effects which might be connected to
channel 2). An optional footswitch plugged into the EFX
FOOTSWITCH jack on the back panel may be used to
activate or bypass the internal effects (only).
MASTER Volume
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 presets 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 illuminates. 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 presets 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 amplifier 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 single,
mono input on the mixer, use the LEFT/MONO jack.
