Rear Panel Facilities
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
amplifier 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
RETURN 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 optional Ashdown 4 way footswitch only
(available from your Ashdown dealer, or
online at www.ashdownmusic.com/shop).
Always connect this prior to turning on the
power to the amplifier as the footswitch
derives its power from the amplifier and
sends a serial data stream to the amplifier 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.
CROSSOVER AND OUTPUTS (Rack Preamp
only) - The BASS MAGNIFIER RACK PRE-AMP
has a built in high precision CROSSOVER with
separate jack socket outputs for the HIGH
PASS and LOW PASS signals.
Crossover frequency is adjustable from 35 to
160Hz with a level control for the LOW PASS
output to adjust the balance between LOW
and HIGH outputs signals.
There is also a FULL RANGE jack line output
provided.
This section is provided with switched output
levels for simplified connection to power
amplifiers that require either a 0dB or +4dB
signal level. This switches the levels of all
three outputs.
SPEAKER OUTPUT (except Rack Preamp) -
The Speaker Output sockets are also situated
on the rear panel of the unit.
