Owner's Manual

CONGRATULATIONS on your purchase of Carvin’s RX800, RX1200 or RX1200R mixer!
The "
R" version is a non-powered rack model designed for use with your own power amps while
the
RX800 and RX1200 models include built-in high power amplifiers for direct hook-up to your
speakers. Please read this manual carefully to take advantage of the many features of your mixer.
SUPERB SOUND is derived from the extremely low distortion, high "Headroom" design. A
state-of-the art, low noise, high headroom, balanced XLR preamp for each channel features a
common mode rejection of better than 78 dB, which means that any possible noise that may
come over your cables is virtually eliminated. Even the balanced XLR output connectors guard
your system from cable noise for professional recordings or external power amp connections.
Distortion is nearly non-existent with THD below .1%, which guarantees the purity of your sound.
Hear the difference - your sound will not seem "sterile" or "processed". It will be dynamically
open and transparent just like it was meant to be!
LIGHT WEIGHT and EASY TO USE controls are logically laid out, making the RX Series
simple to use - quick adjustments can be made easily. Its compact size and weight of 30 lbs.
makes it the lightest, most powerful mixer of its kind. No other competitor in the industry offers
a higher performance to weight ratio!
4 HIGH CURRENT AMPLIFIERS deliver 300 watts RMS each. A total of 600 watts is
delivered to your main speakers, plus two 300 watt amps to drive your stage monitors for a total
of 1200 watts. Speaker outputs feature both Twist-Lok and 1/4” jacks, delivering full power into
4 ohms, making these mixers more powerful than most amplifiers rated at 2 ohms. A peak indi-
cator for every amp and a protect LED gives you a visual monitor.
A HIGH CURRENT POWER SUPPLY is provided by a beefy toroid transformer to assure
continuous high amperage DC voltage to all three power amplifiers, eliminating "overload" or shut-
down. 20,000 mfd capacitors offer a large power reservoir for bass thumping output.
The
RX1200R features a 125k Hz switching power supply for operating your mixer at any volt-
age from 90 VAC to 240VAC. Like a laptop computer, you can go anywhere in the world and not
worry about power adapters.
2 INDEPENDENT 24-Bit STEREO DSP EFFECTS allow you to independently
assign each channel to your choice of simultaneous effects. You can dedicate chorus/rev to the
acoustic guitar channel and reverb to the vocals, etc. Both effects are assignable to your stage
monitors so you can hear yourself with full effects. The effects processors feature 256 effects
each, including reverbs, choruses, flanging and echoes, with parameters fully adjustable for;
damping, decay
, depth, speed, regeneration and time.
ACTIVE 3 BAND CHANNEL EQ provides easy adjustment for the tone you want. The
LO frequency controls start at 20 Hz and continue through 80 Hz for a solid non-flabby bass. A
simple adjustment with the MID control gives you the best sound for vocals or guitar in the ver
y
important 750Hz frequency range. The 11.5k Hz HI treble control adds sparkle to your top-end
without adding harshness. Both the LO and HI are "shelving", which means they are effective
from 20Hz up to 20k Hz.
FOUR 7 BAND EQUALIZERS provide precise adjustments to fine tune your overall sound
and to help control feedback. Unlike one stereo graphic equalizer
, four independent 7 bands give
you total control over each power amp output.

DISTORTION-FREE LIMITERS
The purpose of a limiter is to hold down peaks so the amp won’t distort even with
extra hot input signals (this protects your expensive speakers). In addition, limiters
can increase your amp’s average output by 3 db or more. Part of Carvin’s design
uses the more expensive, distortion-free linear “opto isolators”. Unlike amps that use
FET controlled limiters which can inject small amounts of distortion, our limiters keep
your sound pure and uncolored!
ENGINEERED TO LAST Every RX Series mixer is housed in a rugged rein-
forced steel rackmountable chassis. Continuous full power is assured from a 370 sq
inch, high-grade 6063-T5-aluminum heat sink cooled by a quiet variable speed fan.
You’ll never have to worry about protect or power reduction modes. Hidden deep in
the heart of these mixers is the “SMT” Surface Mount Technology construction that
utilizes surface mounted components to prevent parts from shaking or vibrating
loose. Sealed controls and switches guard against the outside elements while heavy-
duty connectors provide a positive connection to your cables. Fire retardant FR-4
military spec circuit boards feature double-sided copper construction to guard
against noise and radio frequencies (RF). Precision 1% tolerances guarantee that
your settings will be accurate every time. The RX Series is professionally made in the
USA for years of service!
