INTRODUCTION
Congratulations on purchasing the dbx 160A Compressor/Limiter. We recommend you take a moment and read through
the manual as it provides information that will assist you from system installation to operation to special applications.
Features include:
¥ OverEasy¨/Hard Knee Selection -- allows selection between our famous OverEasy compression curve and the classic
ÒHard KneeÓ curve popularized by the original dbx 160, 161 and 162.
¥ True RMS Level Detectionª -- senses the power in the program in a musical manner, much as the ear does, giving
results superior to peak or average detection.
¥ Hardwire System Bypass Button -- allows the audio to pass even if the unit is unplugged, and is also useful for compar-
ing the processed and unprocessed signal.
¥ Front Panel SLAVE Button -- couples two 160As together for stereo operation at the push of a button. Note: a 160A
unit cannot be stereo-coupled with a dbx 160XT, 160X, 160, 161 or 162 unit.
¥ True Power Summing -- When two 160A units are slaved together, the RMS energy of the signal presented to the slave
unit is summed with the RMS energy of the signal presented to the master unit to prevent phase cancellation of the two
signals from causing unmusical compressor action.
¥ LED Displays -- 19-Segment LED Display for high resolution monitoring of True RMS INPUT and OUTPUT
LEVELs; 12-Segment LED Display for GAIN REDUCTION (up to 40dB).
¥ Meter Calibration -- Input/Output meter calibration, so the 160A can be used in a variety of situations where the Т0У ref-
erence is not consistent.
¥ XLR-type Input and Output Jacks -- because the 3-pin XLR connector has been recognized as the most durable and
widely used connector for professional applications. (An optional output transformer is available.)
¥ Input and Output Jacks -- with the output capable of driving its own additional 600½ load (single-ended) in addition to
any load on the XLR output.
¥ Input Ground Lift Switch -- internally disconnects pin 1 of the input XLR jack from 160A chassis ground to eliminate
any ground loop hum problems that may arise.
¥ Detector Input -- useful for special applications including frequency conscious compression in which an external equal-
izer is used.
¥ DC-controlled Parameters -- the signal does not pass through any of the parameter controls. Instead a DC voltage con-
trols all functions; this eliminates any possibility of potentiometer noise developing over time.
