wide range of configurations
X-Eight consoles are supplied with either 24, 32, 40, or 48 mono
input channels, plus four full-featured stereo line-input channels—
which can also serve as effect-returns.These standard configurations
include Master and Group modules—all other inputs may be
ordered as mono-mic/line or stereo-line, in four-channel blocks.
microprocessor-based muting system
The X-Eight RT’s straightforward microprocessor-based muting
system was co-developed with JL Cooper, and combines muting
flexibility with ease of operation. Eight manual-mute groups are
provided, each with a dedicated activation-switch, any number of
which may be activated at one-time.The system includes 128 MIDI-
based sequential scene mutes that can work alone, or in conjunction
with the manual mute groups. Scene mutes can be controlled via
external MIDI signals, and each of the 128 mute scenes may be pre-
set to issue a MIDI program-change command to an external device.

features
The X-Eight RT console is designed specifically for sound contract-
ing, industrial, rental, and installation applications. A live perfor-
mance, front-of-house console suitable for veterans and beginners
alike, the X-Eight RT includes identical four-band eq on all mono
and stereo input channels. Auxiliary sends 5/6 and 7/8 may be
switched between mono or stereo operation. Signal monitoring is
provided on all input and output fader channels, assisting the
operator in setting correct gain structure throughout the console.
Stereo full-facility input channels are used for effect-returns on all
faders. Independent recording output and tape monitoring facilities
are provided that will not interfere with live-performance produc-
tion, and which may also be used as special-effects outputs and
additional line-input facilities for theatrical applications. A micro-
processor-based muting system is provided on both inputs and
outputs, and may be operated manually or in sequential-mode.
sound fundamentals
Even in the most demanding environments, the sonic performance
of the X-Eight RT is sure to please discriminating sound engineers
and audiences alike. The X-Eight’s circuitry delivers both extended
headroom and low-noise: exclusively employing the latest-genera-
tion of integrated circuits and studio-grade proprietary-design
microphone pre-amplifiers.The X-Eight RT console exhibits excep-
tional phase-shift performance, revealing less than +/-30 degrees-
of-shift from input to output—significantly better results than most
consoles, regardless of price.
built to defy murphy’s law
X-Eight RT consoles are manufactured to the same exacting
quality-standards as all Crest Audio console products. Each input
channel has its own discrete vertically-mounted circuit board, for
greater impact resistance and serviceability. All circuit boards
employ plate-through double-sided glass epoxy construction—
providing greater strength and integrity. The console’s road-worthy
external frame is fabricated from 14-gauge galvanized steel.
X-Series power supplies utilize amplifier-engineering technology to
deliver stable voltages and long-term reliability, and provide built-in
facilities for a redundant back-up supply—ensuring that the show
will always go on.
