Congratulations on the purchase of your new MAC 1

T-Rex grants a 2-year warranty against defective parts or workmanship.
In the event of a defect, please contact the nearest T-Rex dealer.

The MAC 1 is an analogous programmable switching/line mixer module that is designed for use in stereo or
mono guitar and bass rigs.
The module provides total control over modern and vintage pedals, midi and non-midi processors/effects, amp
selection, channel switching and VCA-control.
MAC I is in principle divided into 4 separate sections. These sections will remain separate until connected via
cables on the rear panel.

1) The Loop section:

MAC 1 offers 8 serial loops (6 in mono - 2 in stereo).
The audio path contains no active circuitry to insure no loss of tone and complete transparency to your
sound.
All loops can be switched on/off independently in every possible conguration.
Use the Loop section for simple in/out switching of your vintage-stomp boxes, preamps, EQ-units, compressors
etc. and/or as an amp selection control for multi amp set-ups for switching between up to 8 different amps.

2) The Line Mix section:

Contains 2 parallel stereo loops that are 100% programmable from 0 (fully dry) to 127 (max effects).
Use the FX line mixer to blend the signal from effects processors, chorus units, delay, reverb and similar time
based effects with the direct signal.
Both line mixers can be real time controlled with an expression pedal.

3) A/B switching:

The A/B switching is used to control footswitch able devices like a channel switching preamp,
combo/head.

4) VCA-control:

The VCA-control is an active volume control that enables you to control your overall stereo/mono volume
with an expression pedal via your MIDI board.

If you are fed up with dancing ballet on top of a tangled mess of pedals and cables in order to change sounds,
the MAC 1 provides you with a rst class opportunity to clean up the stage area in front of you.
Tug your stomp boxes away in your rack and get a clean, shorter signal path avoiding unnecessary cable lengths
causing signal loss, “thin” sound and excessive noise.
Each loop is controlled by a gold plated relay and is the perfect place to connect your stomp boxes and effects
processors in their natural order.
