handled with ease. Signals are automatically routed to appropriate sections of the
console for each recording operation. One of the key features of the MX2488 , but
not found on many P.A. "recording" consoles is an independant control room
monitor mixer with buss/tape sourve selection. This section makes buss
interconnects (for overdubbing) and sub-group effects routing extremely easy.
One of the most important considerations when analyzinga recording console
is the quality of the input pre-amps and equalization capabilities. CARVIN refused
to cut corners in these areas. Equivalent input noise is -128dB utilizing an ultra-
low noise differential mic pre-amp. THD is typically less than .03% @ 40dB gain,
0dBv from 20Hz to 20kHz. This quality spec is preserved throughout the console by
carefull attention to grounding & gain structure. Each channel features three
band continuously variable parametric equalization with bypass switching. This
is a high performance, extremely quiet and musical sounding equalizer. It will
handle the most critical of EQ needs making it a very effective tool i n
compensating microphone responses for various mixes.
Each input of the MX2488 console features an input "Gain" control for both the
line & mic inputs, four auxiliary mixing busses with pre/post switching, muting,
soloing, and odd/even pan controls for sub-group routing. Each channel's volume
control is a 100mm smooth operating "slider" type control for precise control of
signal processing imaginable.
The ouput sections of the MX2488 features independent control room
monitoring, made possible by the (2) Track Faders and "Pan" controls provided on
each output channel. A "Tape" switch is provided at each output channel to allow
the tape playback signal to feed the cue and control room mixes. This means that
valuable input channels do not have to be used to return tape playback signals
when doing overdubs.

Some of the quality components used throughout the consoles include the
professional signal connectors (3 pin & 1/4") and highly reliable ITT Schadow
switches. Large professional VU meters are accurately driven by a well damped
circuit and are easy to read. Long throw 100mm faders have a precise 15% audio
taper for smooth fade-outs. They feature integral dust shields for smooth
operation and long life. The rotary pots are optimally damped for smooth reliable
operation. All of the knobs have easy to read pointers and are color coded b y
function.
Construction of the MX2488 is modular, with individual circuit boards used
for each channel and master strip. Virtually all hand wiring has been eliminated
through the use of highly reliable circuit board and computer type ribbon cable.
All circuits are engineered for lowest possible noise and extreme reliability. A n
internal heavy duty power supply spares the expence and inconveniece of a
separate outboard supply and is located in such a way that system noise is not
affected. Tight voltage regulation helps keep crosstalk low while current limiting
protects the supply from accidental shorts. AC power is supplied to the mixer by
way of a standard detachable international line cord with safety ground. The
chassis is made of precision formed steel with long life pem-nut fasteners and a
durable epoxy finish. One inch thick solid oak ends and a padded hand rest add to
the good looks and overall aethetics of the MX2488 console.
