Rear Panel Section - RedPlate ShredPlate Operation Manual

RedPlate ShredPlate Operations Guide
IEC Module – contains the main power switch, power cord inlet connector and the fuse drawer
which doubles as the voltage selector on export models. To access the fuse(s) use a small flat
blade screwdriver in the notch at the bottom of the power cord inlet connector, the drawer snaps
out in a rearward direction. The ShredPlate can accept both the larger (3AG footprint) or smaller
European (5mm X 20mm) fuses. A time delay variety (SLO-BLO) is recommended. When the
export version becomes available, the fuse drawer can be rotated for voltage selection, make sure
the correct value fuse is located on the same side of the fuse drawer as the desired selection
arrow. Line up the appropriate arrow on the fuse drawer with the arrow on the bottom right of the
module for the proper VAC selection.
Standby Switch – This switch allows the tubes to warm up before operating the amplifier. Wait
1 minute after power on to move it up to the operate position. For improved tube life and
performance do not leave the amplifier in Standby position for longer than 20 minutes (better to just
leave it in operate mode during performance intermissions).
100 WATT / 50 WATT Switch – This switch changes the output tube by lifting the center pair of
output tubes (V8 & V9) enough to be irrelevant. The impedance selector does not have to be
changed in 50 watt mode.
Bias adjustment and bias test point – Allows external access for bias adjustment (see bias
procedure in the Maintenance section).
LINE OUT – A line level signal jack derived from the speaker output which contains the whole
tone of the amplifier.
Speaker Jacks – The MAIN and EXT jacks are wired in parallel. The MAIN jack must be used
first because it has a protection device. ALWAYS HAVE A SPEAKER CONNECTED TO AVOID
PERMANENT AMPLIFIER AND OUTPUT TUBE DAMAGE.
Impedance Selector Ω - Set this to the total impedance of all attached speakers.
Depth Control – Works within the presence circuit to adjust the contour of negative
feedback, higher settings allow more low bass to come through. The control has no effect
when the front panel Presence control is rotated to the bypass position.
Master2 Control – When engaged with the footswitch it is Identical to the front panel Master
Control. Useful for setting a solo volume boost.
SEND and RETURN Jacks – The send jack connects to the input of an external effects device
and the return jack connects to the output of an external effects device. The return jack interrupts
the signal path so the external effects unit must mix the wet and dry signals.
Footswitch Jack - This is a standard 180 degree 5 pin DIN jack for footswitch connection. If a
replacement cable is needed, make sure all 5 wires are supported. The pinout is conveniently
located on the rear panel for use with automated switcher conversion boxes.
