Front Panel Facilities (continued)
DIRECT INJECT (D.I.) - A balanced D.I. is
provided on a latching XLR socket. This has a
push button placed below it that allows the
user to choose either a Pre E.Q. signal (button
pushed IN) or a Post E.Q. Post Sub and effects
signal (button OUT).
The output signal from this XLR socket is set
to a level and impedance suitable for
connecting directly into the Microphone
input of a mixing 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. An 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.
The signal from this socket remains when all
other outputs from the amplifier are Muted
allowing all sound from the amplifier to be
silenced while tuning is in progress.
LINE OUT -This output socket provides a line
level/post Output Level control signal for
connection to an external power amplifier
driving additional speaker cabinets.
OUTPUT LEVEL - The OUTPUT control
adjusts the overall level of the amplifier.
Adjust this for your preferred overall stage
playing volume.
