22-HEAD
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 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 22-HEAD has one power section rated at 600
Watts RMS with two Neutrik combi speakon out-puts. You can either use
Speakons or Jack Speaker cables to connect to your cabinet. Each Power
section has a minimum load of 4 ohms.
