This fuse protects the DC power within the amplifier. Use only the correct size and rating fuse as
specified on the panel. If a fuse blows or fails and a replacement of the same size and rating is installed and it in
turn blows, the amplifier has suffered a malfunction, at this point check the output valves and replace faulty one if
required. Should the valves not be the problem the amplifier should be checked out by a qualified technician. Do
not try using a fuse of greater value. Using fuses that are too large in current rating may cause serious irrepairable
damage to the amplifier. Fuses are designed in to PROTECT, DO NOT take chances.
Use to connect an 8ohm extension cabinet, model number GS212PE.
When an extension cabinet is connected the resultant impedance will be 4 ohms and the speaker impedance
switch should be set to 4 ohms. Mismatched impedance will reduce tha amplifiers performance and in some cases
may cause damage to your amplifier.
This switches the internal impedance setting of the amplifier. When
using with the 'on board' speaker set to 8 ohms. When an 8 ohm extension cabinet is also connected, set to 4
ohms.
1/4" output jack factory connected to the 'on-board' speaker. With no
extencion cabinet connected ensure that switch (5) is set to 8 ohms.
This socket is provided to allow a signal to be fed directly to the power amplifier from
an effects unit or other pre amplifier. Connection at this point disconnects the internal pre- amplifier. Nominal
level 0dBu.
This socket provides an output from the pre-amplifier, post FX loop and may be used
to drive other power amplifiers, FX units or mixing desks. Nominal level 0dBu.
This is factory set to suit the valves fitted (5881). Should you wish to use EL34 valves the bias
switch should be re-set accordingly.
This is a 5 pin 180 DIN socket for connection of the dedicated footswitch FS4 as
supplied with the amplifier. FS4 is a four way switch for remote on both channels and reverb.
This control adjusts the signal level returning from an external FX unit and allows the
correct mix to be achieved. This may also be used to provide additional pre amp gain for both channels when the
switch is deployed in the insert mode regardless of whether an effect unit is connected or not.
This is provided to recieve the output of an external FX unit being driven from the send
socket (14)
For normal amplifier operation without FX this should be set to 'BYPASS' mode position.
When the whole of the amplifier signal is required to be directed to an external effect, such as a Graphic Eq the
switch should be set to ' INSERT' mode. The 'SIDE CHAIN' mode allows the connection of FX units such as
delays, flangers etc, where a direct signal path is maintained to avoid the normal loss of dynamics through FX
processors. When using this mode any FX unit should if possible be set to 'EFFECT ONLY' mode.
This provides an output from the pre-amplifier to drive effects units in conjunction with
(12) & (13). Nominal level 0dBu.
This socket provides an output from the pre-amplifier for
sending to an external FX processor. Processors fitted here operate in a 'side chain' mode and should be set for
effect only operation if possible. Nominal level 0dBu
