dbx 160A COMPRESSOR / LIMITER

QUICK SETUP

To get your unit up and running as quickly as possible, do the following steps . For more detailed information, refer to the

specified pages .

• Unpack and Inspect the 160A Package.

• Set Levels and Controls as Needed.

• Connect the 160A to Your System.

INSPECTION

Verify that the 160A package contains the following:

• 160A Unit

• AC Power Cord

• Operation Manual (including Registration Card)

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

"Hard Knee" curve popularized by the original dbx 160, 161 and 162.

• True RMS Level Detection™ -- 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 "0" 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 600Ω 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.
