ATOMIC AMPS REACTOR 50/50 MANUAL
2
THE ATOMIC REACTOR 50/50 STEREO POWER AMP is a rackmount, 2 × 50W
amplier 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” amplier, created with the stage or studio
guitarist in mind. It is also ideal for acousc guitars, vocals, electronic
instruments, and any other applicaon where a high quality stereo
amplier is needed. The 50/50 delivers full-rated power over a full-
frequency response, with high headroom and very low distoron. In other
words, this is an amp without an opinion; it amplies but does not alter the
character of the sound.
Each channel of the 50/50 is a fully independent 50W amplier 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 ne adjustments on-the-
y and even allow the unit’s channels to operate with two dierent 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 tradional 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.
