Summary

Important Safety Information

General Safety Precautions

Provides warnings about electrical hazards, user serviceable parts, liquid exposure, and storm precautions.

Electrical Connection and Wiring

Details mains socket connection, protective earthing, and color coding of wires for safe electrical connection.

Warranty

Connecting the 1066 to your system

Operating Controls

Front Panel Controls

Details the layout and functions of the front panel controls for the dbx 1066 unit.

Stereo Link Switch

Explains the function of the Stereo Link switch, enabling stereo operation and master/slave configuration.

Expander/Gate Threshold Control

Sets the level below which gating or expansion occurs, with a range from -60 dB to +15 dB.

Expander/Gate Ratio Control

Sets the expansion ratio, varying from 1:1 to 8:1, featuring a soft-knee OverEasy® threshold circuit.

Compressor Threshold Controls and LEDs

Sets compressor threshold and indicates signal level relative to it, including OverEasy® status.

OverEasy® Switch

Provides a smooth transition into compression, reducing artifacts and allowing faster attack times.

Compressor Ratio Control

Selects the compression ratio from 1:1 to infinity:1, with smooth transition in OverEasy® mode.

Attack Control

Sets the time for the compressor to begin acting on a signal above the threshold, from 3 dB/msec to .04 dB/msec.

Release Control

Determines how quickly the compression circuit returns the input to its original level, from 250 dB/sec to 5 dB/sec.

Output Gain Control

Adjusts the output gain of the compressor, variable from -20 dB to +20 dB.

PeakStopPlus™ Level Control

Sets the output signal reduction level to prevent transient clipping, using a two-stage limiting process.

Applications

Fattening Kick Drums and Compressing Other Drums

Techniques for tightening kick drums and compressing other drum sounds using the 1066's features.

Speaker Protection

Utilizing the 1066 for limiting to protect power amps and drivers from excessive program levels.

Preventing Digital Recording Overload

Ensuring audio input does not overload digital recorder's A/D converters by using specific 1066 settings.
