Product Features

Three balanced XLR inputs per channel plus three unbalanced (RCA)
inputs per channel.
Preamp Out in both balanced XLR output and unbalanced (RCA)
outputs per channel.
Tape input and output jacks allow tape recording from any source and
monitoring of tape recorder output.
Rear panel handles assist moving and transport of unit.
Chassis and all chassis components, precision machined from 6061
aluminum plate, reduce distortion resulting from mechanical resonance
and thermal instabilities.
All operational functions under microprocessor control. Within five
seconds of any function selected, the microprocessor reverts to a non-
clocking "sleep" mode which eliminates any possibility of digital noise
contamination.
Non-multiplexed, zero electrical noise generating numerical display
indicates volume level over entire range of 99.5 decibels.
'Display off after five seconds' option available for non-intrusive, low
light listening environments.
Introduction / Product Features
Dual range volume control allows large volume level changes when
knob is rotated abruptly, yet permits precise small volume level changes
when knob is rotated slowly.
Optional plug-in phono cards (installed internally) convert Line Input 1
to high performance phono inputs. Four gain and input loading options
standard for moving magnet and moving coil cartridge types.
Full electronic and thermal protection modes guard against output
overloads and short circuits.
High current preamp outputs (balanced XLR and unbalanced RCA)
allow simultaneous driving of external power amplifiers for subwoofers,
vertical bi-amping, etc.
All inputs are transformer-coupled to provide maximum immunity from
RF contamination and system ground loops and enhance compatibility
with a wide variety of interconnected components.
Speaker outputs are fully balanced to provide maximum sonic
performance and immunity from RF contamination due to high output
common mode noise rejection.
Optical encoder type volume control maintains quiet, trouble-free
performance and accuracy over entire lifetime of product.
Six-function hand-held IR remote control.
