Product Features

Seven balanced XLR inputs per channel.
Two balanced XLR main outputs per channel.
Two balanced XLR record outputs per channel.
One balanced XLR "bypass" input per channel for use in home theater
installations.
All inputs and outputs can be used with single-ended RCA terminated
interconnects by using XLR/RCA adapters (one male stereo pair and
one female stereo pair supplied).
Independent Listen and Record functions on each input permit
simultaneous listening and recording from any two selected inputs.
Each input can be individually adjusted for R/L balance, mono/stereo,
absolute phase, input impedance, and gain, exclusively independent
of every other input. Individually adjusted input settings are
automatically memorized and recalled when returning to that input.
Built-in "pink noise" generator facilitates break-in of preamplifier
components and interconnected associated components.
Six-function hand-held IR remote control with separate IR sensor/
display unit for remote IR reception and volume level indication.
Chassis and all chassis components precision machined from 6061
aluminum plate provide maximum mechanical resonance control.
Introduction / Product Features
All operational functions are under microprocessor control. Within five
milliseconds of any function selected, the microprocessor reverts to a
non-clocking "sleep" mode which eliminates any possibility of digital
noise contamination.
Transformer-coupled inputs and main outputs provide maximum
immunity from RF contamination and system ground loops and enhance
compatibility with a wide variety of interconnected components.

Power Supply Features

Separate power supply provides a stable, low noise DC power source
utilizing reliable, long-life sealed lead-calcium batteries.
Microprocessor controlled charge-management system ensures optimum
battery operation under all conditions. The microprocessor is normally
in non-clocking "sleep" mode, except when servicing a short-term
operational command.
Two separate power supply outputs for powering additional
companion units such as an optional phono equalizer.
Front panel AC/DC mode switch disconnects AC power when DC
mode (pure battery) operation is selected.
Chassis and all chassis components precision machined from 6061
aluminum plate provide maximum mechanical resonance control.
