Overview:

(Continued)

Without further delay, connect up your favorite preamp and get ready to experience one of the

most commanding sounds in rack-mount history as

Recto power goes stereo for the first time in this amazing package.

NOTE: BEFORE YOU MOUNT THE 2:100 IN YOUR RACK! This is an extremely aggressive and powerful amplifier intended for use
with one of the above mentioned MESA preamplifiers in large venues. If after trying it you feel you may have chosen more amp than
you need, you may find one of the more forgiving MESA strereo power amplifiers such as the Stereo 2:50 or the Stereo Simul-
Class2:90 more suited to your style or application. Save the packing material and keep the amplifier in perfect condition and you
should be able to return it to the place of purchase for full credit toward one of the less aggressive models that might perhaps better
suit your needs. If this stunning, agressive power well suits your playing style and needs, congratulations and by all means rock on.

And now on to the controls and features of

your new 2:100. Please take some time along the way and read this operating manual,

it will prove to be quite worth while in the end and will help you to enjoy

your new amplifier to its full extent.

LEVEL CONTROLS:

Each channel of the

2:100 has its own LEVEL Control. If the amplifier is being fed by signals from a typical

pre-amp, try a setting of 2 as a starting point. If the amp is being fed by lower-level signals such as those from (minus) -20db type
effects units, etc..., you may need to raise the Levels as high as 2:00 or 3:00.

NOTE:

Remember to turn the LEVEL Control to zero on any channel not con-

nected to a speaker or load resistor! A Load must be present at all times when
either channels’ LEVEL Control is dialed to anything other than zero. Failure
to comply to this procedure can cause serious damage to your 2:100’s power
section.

PRESENCE CONTROLS:

Each channel on the

2:100 has its own “active” PRESENCE Control. These controls provide a boost

in the upper mid-range/lower Treble zone, which are the frequencies that tend to get obscurred in the energy of live performance; use

them when you need to cut through a “loud mix.”

Use these PRESENCE Controls with discretion as they can make for some ear
damaging, almost harsh sounds if set too high - especially if the TREBLE Control
on your pre-amp is dialed up extremely high.
