QUADRA/FX REAR PANEL CONTROLS & CONNECTIONS
Despite the Quadra/FX’s sophistication, it is easy to interface the unit with other equipment. All inputs and outputs are
located on the rear panel. Standard ¼” inputs and outputs make patching simple.
Note: For best audio quality, always use high-quality cables.
The Quadra/FX is designed for line level or instrument operation. We don’t recommend plugging microphones directly
into the processor. Instead, either use a preamp, a mixer, or an amp’s preamp section to first boost the mic’s level,
then use the effects loop output or reverb send. High signal level from a preamp or effects loop assures an optimum
signal-to-noise ratio in the Quadra/FX, keeping hiss and distortion to a minimum.

POWER JACK INPUT
An external AC adapter powers the Quadra/FX. Plug the adapter into this jack and then into a power outlet.
Use only the adapter that came with the Quadra/FX. If the adapter ever becomes damaged, immediately
discontinue use.

MIDI IN & MIDI OUT
Use the MIDI In jack for receiving program change, continuous controller, note, and system exclusive
messages. It enables you to “talk” to the Quadra/FX from an external source such as an X-11, an X-15
Ultrafoot, an outboard sequencer, or a computer equipped with MIDI ports and associated software.
Use the MIDI Out jack for performing a MIDI data dump. It connects to any external device capable of
recording MIDI data and allows the Quadra/FX to off-load the contents of its memory. The MIDI Out jack does
not act as a MIDI Thru, so the Quadra/FX should be placed at the end of your MIDI chain.

OUTPUTS #1–4
All four Outputs are single-ended (unbalanced) ¼” jacks with low impedance. The use of each output jack is
determined by a preset’s internal routing. For example, Cascade and Stereo Routings do not use Outputs #3
