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 in conjunction with the OUTPUT LEVEL
VU Meter.
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 Ashdown
4 way footswitch (sold separately) only. 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 (on the FS4) 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 HOD has one
power section rated at 666 Watts RMS with two Neutrik
combi speakon out-puts. The Power section has a minimum
load of 4 ohms.
