LINE INPUT - The rear panel has a Line Input
socket for connection of other signal sources
into the system. This can be used for plugging
a CD, Tape or MP3 player into the amplier for
practising, rehearsing or for connection of a
second pre-amp into the system.
EFFECTS SEND / RETURN - A serial effects
loop is provided at a level of 0dB.
The EFFECTS SEND socket can also be used
as a Line Out socket if required as the signal
path through the preamp is only broken when
a jack plug is inserted into the EFFECTS RE-
TURN socket.
The EFFECTS SEND is situated after the EQ,
the Valve section the Compression and the Sub
Bass Processor.
4-WAY FOOTSWITCH SOCKET - For the 4
way footswitch to operate it is essential that the
corresponding front panel push buttons be in
the OUT position.
This is a mono jack socket for connection of the
Ashdown 4 way footswitch (sold separately)
only. Always connect this prior to turning on the
power to the amplier as the footswitch derives
its power from the amplier and sends a serial
data stream to the amplier in order to operate
the various functions.
Each of the 4 facilities available for selection
is indicated by an LED that will light when that
facility is selected from the footswitch.
SPEAKER OUTPUT - The Speaker Output
sockets are also situated on the rear panel of
the unit. The ABM-600H & RC has one power
section rated at 600 Watts RMS with two Neu-
trik combi speakon out-puts.The ABM-1200H
has two power sections rated at 600 Watts
RMS each with two Neutrik combi speakon out-
puts per power section, labelled A & B. You can
either use Speakons or Jack Speaker cables
to connect to your cabinet. Each Power section
has a minimum load of 4 ohms.
