Aux Input
(Stereo)
The Auxiliary Input on the rear panel accepts a ¼” stereo or monaural
plug and may be used to inject audio from a CD, MP3 player or other
line level source, for home practice or live gigs. Use the
Aux (stereo)
Level
control on the front panel to set the desired music level.
The Aux Input provides a secondary input to the amplifier that sums into
the system such that it can be heard via the headphones, main speaker and
XLR Direct Out. The Aux Input is a stereo ¼” TRS Jack input; signals
fed via this input in stereo will remain in stereo when fed out to the stereo
Headphones jack. Signals fed via this input are summed to a mono signal
before being fed to the speaker and XLR Direct Out.
This input can be used in one of three ways:
i)
A CD / MP3 Player connected to the Aux Input will allow tracks to be
played for practice and small gigs.
ii)
An additional effects processor output can be returned via this input.
iii)
A guitar effects unit output can be connected into this input, enabling
the amplifier to be used for both steel and guitar.
Note; this input is optimised for a 0dB line level signal.
Note; Signals applied to the Aux Input will be analog modelled when
output from the Direct Out.
It can also be used as a second effects return. If used as second effects
return, the rear tuner out can be used as effects send. See FAQ sheet.
Speaker Wire
(Red and Black)
This is the bridged output to the speaker. The speaker impedance must be
greater than 3 ohms.
The red wire is (+) or positive phase, the black wire is (-) or negative phase.
CAUTION
Both wires have an AC voltage on them. DO NOT allow them to
short to ground when you should hear sound, as this could cause a failure.
NEVER use grounded equipment to measure the speaker output.
