RedPlate RP50R Operations Guide
LINE OUT – A line level signal jack derived from the speaker output which contains the whole
tone of the amplifier.
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.
Reverb Control - Sets the amount of reverberation effect, takes the reverb out of circuit when
rotated to zero (there will be a slight volume and tone change).
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.
Fat/ Humbucker / Single coil Switch – Sets the amount of bass gain in the input of the clean
preamp stage, useful for matching the amplifier to the guitar type.
The RP50R comes complete with a footswitch and a footswitch cable. The cable used is a
regular MIDI cable and is readily available in any length at most music stores.
TWEED – When engaged (lit) the guitar input is routed to the Tweed channel. The footswitch
button does not work when the Blackface Channel's volume control is pulled because it overrides
the footswitch.
DRIVE – Character Boost feature. When lit, the Drive section of the amplifier is active, not lit,
means the section is bypassed. The footswitch button does not work when the Drive section's Gain
control is rotated to zero because it is a duplicate function.
BOOST – Girth Boost feature, it, adds volume and tone by doing a partial tone stack lift on the
Blackface channel or a full tone control lift on the Tweed channel. The footswitch button does not
work when the Blackface channel is active and the Blackface preamp's Bass control is rotated to
zero (because it is a duplicate function).
MID – Girth Boost feature. If the Tweed channel's tone control is pulled (Brownface mode) the
MID button is the equivalent of pushing in the control knob to the normal Tweed mode. The MID
button has no effect on the Tweed channel if the Tone control is not pulled. On the Blackface
channel the MID button increases the size of the treble capacitor for more upper midrange.
