Ada MP-1-CHANNEL User Manual page 3

Note that the connector is a 2.1mm with the center pin negative, the most common
configuration for effects pedals. There is no 9V battery in the MP‐1‐CHANNEL, and the MP‐1‐
CHANNEL will not work with a 9VDC power supply, nor will it work on a 12V power source
with less than 800mA of current.
APPLICATIONS
The MP‐1‐CHANNEL was designed for pedal boards and direct recording. You can precede it
with other pedals and effects or you can place them after the MP‐1‐CHANNEL. Most common
effects after the MP‐1‐CHANNEL are delays, cabinet simulators, and reverb. Some guitarists
will want the MP‐1‐CHANNEL to perform the function of a preamp, and will want its OUTPUT
to connect to a combo amp's power stage via a "direct insert" jack or the effects return loop
jack. This avoids a preamp plugged into another preamp situation, which is, in most cases,
undesirable. If your combo or head does not allow direct access to its power amp, you can
plug into the combo or head's input. When doing this, it is best to set the tone controls "flat"
and "drive" turned down to keep the signal clean with the master volume up. This will allow
the MP‐1‐CHANNEL to be the source of distortion, rather than sharing it with the combo or
head preamp.
For live performance, the MP‐1‐CHANNEL, along with a GCS Cabinet Simulator, can eliminate
the need for a combo or head with a guitar speaker cabinet. You can get incredible tone
through the house sound system (PA) and through full‐range stage monitors or ear monitors.
For direct recording, we recommend a cabinet simulator like one of our GCS products. This will
add the realism of a miked guitar speaker cabinet to the guitar tone coming from the MP‐1‐
CHANNEL, or your pedal board.
