NOTE: No other warranty, written or oral is authorized for dbx products. This warranty gives you specific legal rights, and you may also have other rights which vary from state to state. Some states do not allow the exclusion of limitations of incidental or consequential damages or limitations on how long an implied warranty lasts, so the above exclusion and limitations may not apply to you. 2 Introduction ® Connecting the 1066 to your system To connect the 1066 to your system, refer to the following steps: · Turn off all equipment before making any connections. · Mount the 1066 in a rack Install the 1066 in a rack with the rack screws provided. It can be mounted above or below anything that does not generate excessive heat. Ambient temperatures should not exceed 113° F (45° C) when equipment is in use. Although the unit is shielded against radio frequency and electromagnetic interference, extremely high fields of RF and EMI should be avoided. · Make audio connections via XLR, 1/4" TRS, or 1/4" TS plugs. Both types of connectors for the inputs and outputs can be used for balanced or unbalanced connections. The use of more than one connector at a time for the input/output pair could unbalance balanced lines, cause phase cancellations, short a conductor to ground, or cause damage to other equipment connected to the 1066. · Apply power to the 1066 Connect the AC power cord to the AC power receptacle on the back of the unit. Route the AC power cord to a convenient power outlet away from audio lines. The unit may be turned on and off via the 1066 power switch or from a master equipment power switch.

In stereo mode, Channel 1 is the master and Channel 2 is the slave. Each of the Channel 2 controls and switch functions will be overriden and controlled by the Channel 1 controls and switches, except the Sidechain Monitor, Sidechain Enable, Contour, and Bypass switches. Also, Channel 2's Expander/Gate, Compressor Threshold, and PeakStopPlusTM Threshold meters will be disabled, while both channels' Gain Reduction meters will identically indicate the amount of gain reduction occurring. It is important to note that while Channel 1 is the master as far as the controls go, both channels have equal precedence as far as signal processing is concerned. The dbx 1066 uses True RMS Power SummingTM, an extremely accurate and musical way to combine detector outputs in a stereo situation. The switch will light to indicate that the 1066 is in the Stereo Link mode. Expander/Gate Threshold Control - This control sets the level below which gating/expansion occurs. It has an effective control range of -60 dB to +15 dB. When it is fully counter clockwise to the "off" position, no gating or expansion occurs. Expander/Gate Threshold Below (-) LED - This LED illuminates when the signal is below the level set by the EXPANDER/GATE THRESHOLD control and indicates that expansion or gating is occurring. Expander/Gate Threshold Above (+) LED - This LED illuminates when the signal is above the level set by the EXPANDER/GATE THRESHOLD control and indicates that no expansion or gating is occurring. Expander/Gate Ratio Control - This control sets the expansion ratio and varies from 1:1 to 8:1. It is important to note that as the signal passes below the threshold, the input/output gain relationship does not transition sharply form unity gain (where no expansion is occurring) to the ratio set by the EXPANDER RATIO control. The 1066's expander utilizes a soft-knee OverEasy® threshold circuit ...
