USER GUIDE
desk for either Direct Injection into the PA system or for recording. This
must ONLY be used into a Balanced Microphone input, it is not intended
for any other type of connection.
This has a floating ground that is referenced to the mixing console it is
plugged into and should not need ground lifting. It is also unaffected by
Phantom Powering on the Microphone input.
Make sure your XLR plug does not have the shell of the plug internally
connected to signal ground or this will connect the system to chassis
ground of the ABM and may cause problems with hum.
PUSH TO MUTE - When pushed IN this button mutes the output from
the preamp to the power amp, mutes the output from the D.I. socket and
mutes the output from the LINE Out socket as well. This leaves the output
from the TUNER socket still available to allow muted tuning.
A blue LED is provided next to this switch to indicate when the amplifier
is muted. This function operates only from the front panel MUTE push
switch. i.e. pressing this button mutes all sound from the amplifier and
allows a tuner connected to the TUNER socket to operate for silent
tuning. Release the button and you are back in action again.
TUNER OUT - This output socket provides a line level signal that can be
used for a permanent connection to a tuner.
