Preamplifier Rear Panel
A INPUTS 1-7 (Female XLR): Seven (7) XLR fully balanced or single-
ended inputs (via supplied XLR/RCA adapters) are provided for line
level signals only. Each INPUT connector conforms to a Pin #1 ground,
Pin #2 negative, Pin # 3 positive standard. Both positive and negative
terminals of each INPUT connector are isolated from ground by several
megohms which eliminates the possibility of ground loops and restores
maximum common mode rejection ratio.
B BYPASS INPUT (Female XLR): Accepts balanced or single-ended inputs
(via supplied XLR/RCA adapters) from home theater surround processor
front left and front right outputs.
C MAIN OUTPUTS 1 & 2 (male XLR): Provides parallel XLR fully balanced
or single-ended outputs (via supplied XLR/RCA adapters). Each OUTPUT
connector conforms to a Pin #1 ground, Pin #2 negative, Pin #3 positive
standard. Both positive and negative terminals of each OUTPUT connec-
tor are isolated from ground by several megohms which eliminates the
possibility of ground loops and restores maximum common mode
rejection ratio. Balanced output signals are always provided regardless of
input (single-ended or balanced) signal configuration.
D REC OUTPUTS 1 & 2 (male XLR): Provides parallel XLR fully balanced
or single-ended outputs (via supplied XLR/RCA adapters). Each OUTPUT
connector conforms to a Pin #1 ground, Pin #2 negative, Pin #3 positive
standard. REC OUTPUTS are ground referenced and buffered from any
selected input. Balanced output signals are always provided regardless of
input (single-ended or balanced) signal configuration.
E POWER SUPPLY INPUT (male XLR): Interconnects the Preamplifier to
the Power Supply via the supplied DC power cable. Caution: Use only
the supplied DC power cable and companion Power Supply.
Power Supply Rear Panel
1 RS232 DATA IN/OUT (DB-25 female connector): Provides power and
signal data to the remote sensor/display unit.
2 POWER SUPPLY OUTPUTS A & B (XLR female connectors): Parallel DC
power and signal data outputs for preamplifier and optional companion
units such as phono equalizer, etc.
3 AC POWER INLET: Verify that the voltage indicated on the rear panel
corresponds to the AC mains of your service area.
