A Harman International Company
The compressor shall be a single channel unit, with
an audio frequency response of 20—20kHz +0, -
0.5dB, an electronically floating balanced input
impedance of not less than 38kΩ with a maximum
input level of not less than +24dBu and 1⁄4” TRS
and XLR input connectors. The output impedance
of the electronically floating balanced output shall
be no more than 32Ω (balanced or unbalanced) with
a maximum output level of not less than +24dBu,
into a balanced load with a minimum impedance of
not less than 600Ω, and +21dBu into and unbal-
anced load with a minimum impedance of not less
than 600Ω. It shall use an XLR connector. The out-
put impedance of the separate, 1⁄4" TRS unbalanced
output shall be no more than 21Ω with a maximum
output level of not less than +24dBm. Total har-
monic distortion shall be no more than 0.2% in typ-
ical operation with any amount of compression up
to 40dB. The unit shall have an output noise level
of not more than -90dBu and a dynamic range of
not less than 113dB. Output level shall be gain adjustable from -20dB to +20dB from nom-
inal gain via front panel gain controls and all outputs shall be capable of driving a short cir-
cuit indefinitely with maximum input applied. The compressor attack and release times shall
be program dependent. The compression threshold shall range from -40dB to +20dB, and
the compression ratio shall be variable from 1:1 through Infinity:1 through negative com-
pression to -1:1. The unit shall have a detector input, with a 1⁄4" TRS jack capable of bal-
anced or unbalanced operation. The front panel shall have the following controls and switch-
es:, Bypass switch, Master/Slave switch, Compressor Threshold, OverEasy or Hard Knee
selector switch, Compression Ratio, Output Gain, and Display Selector switch. The follow-
ing LEDs for metering and status indication shall exist: Bypass, Slave, Threshold (3 LEDs),
Input/ Output Display Selected (2 LEDs), Input/Output Level (19 LEDs) and Gain Reduction
(12 LEDs). The unit shall have a 1⁄4" TRS jack at the rear panel, allowing stereo strapping
with a second unit of the same design for stereo operation with true RMS summing of input
levels There shall also be a calibration control for the level meter, at the rear panel. The unit
shall incorporate a detachable IEC mains cable and the power requirement shall be 90—
130VAC 50/60Hz or 200—250VAC 50/60Hz. Dimensions shall be 1.75" x 19" x 6.5"
(4.45cm x 48.2cm x 16.51cm). The net weight shall be 4.41lbs (1.99 kg) and the shipping
weight shall be 6.62 lbs (2.99kg). The unit shall be a dbx 160A Compressor/Limiter.
