RedPlate Magica Operations Guide
LINE OUT – A line level signal jack derived from the speaker output which contains the whole
tone of the amplifier.
Presence Control – The presence circuit uses global negative feedback to remove low
frequencies which frees up bandwidth for more midrange and highs. The effect of this control is
altered by the setting of the DEPTH control (See below for details). The control clicks off when
rotated to zero for no presence.
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 Presence control is rotated to the bypass position.
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.
Humbucker / Single coil/ Fat Switches – Sets the amount of bass gain in the input stage
(separate switches for both Clean and Lead channels), useful for matching the amplifier to the
guitar type.
The Magica comes complete with a 3 button footswitch and a footswitch cable. The cable used
is a regular MIDI cable and is readily available in any length at most music stores.
LEAD – Light on = Lead Channel, Light off = Clean Channel – the footswitch has no effect if
the Volume1 control on the Lead channel is rotated to zero (duplicate function).
GAIN2 – (Lead Channel) Light on = engages the Volume2 and Gain2 controls. Lead channel
footswitch MUST be on for Gain2 to operate.
Boost – (All Channels) Light on = Partial stack lift boost. See "Internal Trimpots" section to set
boost levels.
