is a rackmount, 2 × 50W
amplifier designed for use with guitar or full range speaker cabinets. The
Reactor 50/50
was inspired by the demand for a stereo version of our
popular MB-50 “mono block” amplifier, created with the stage or studio
guitarist in mind. It is also ideal for acoustic guitars, vocals, electronic
instruments, and any other application where a high quality stereo
amplifier is needed. The 50/50 delivers full-rated power over a full-
frequency response, with high headroom and very low distortion. In other
words, this is an amp without an opinion; it amplifies but does not alter the
character of the sound.
Each channel of the 50/50 is a fully independent 50W amplifier with
independent level and presence controls, balanced and unbalanced inputs,
an XLR thru, plus two speaker jacks per side with independent selectable
impedance, allowing a range of speaker cabinets to be connected. It comes
with two 12AX7s and a stereo set of “JJ” 6L6 power tubes. The Reactor
50/50 is also capable of using EL34 tubes. Convenient frontpanel per-
channel bias controls make it possible to perform fine adjustments on-the-
fly and even allow the unit’s channels to operate with two different sets of
tubes.
The Reactor 50/50 is ideal for the modern digital guitar rig. Together
with Atomic Reactor FR Passive Cabs or Wedges (or the traditional guitar
cab(s) of your choice) it ensures that your preamp, modeler or simulator
will sound great, with plenty of power, presence, and punch. It is built to
last, with a heavy duty steel chassis and ¼” brushed aluminum faceplate.
Even as guitar tone processing technology advances, the Reactor 50/50 will
remain a valuable investment in great tone.
