levels and will only be dropped back when damaging signals are present.
Pre-emphasis for broadcast applications
By inserting a pre-emphasis filter network in the detector path of a 1066 processing pre-emphasized
audio, higher levels can be run within the headroom limitations of the broadcast chain.
Anticipated compression
By feeding the program directly to the 1066’s sidechain input and sending the audio signal through a
delay line before the audio input, the unit can “anticipate” the need for a gain change. With some experi-
mentation the effect can be that of “zero,” attack time at any given frequency. Additional signal delays
beyond this “zero” time will then cause the compressor to finish reducing the gain before the leading
edge of the loud passage even enters the signal input. This will suppress the program material preced-
ing this loud passage. The 1066 will then begin to recover from compression (release) before the loud
passage has dropped back down toward the set threshold. This will cause the output level to surge high-
er as the note or passage should be decaying.
Hookups and Cabling: The 1066 is designed for nominal -10 dBV or +4 dBu levels. The 1066 can be
used with either balanced or unbalanced sources and the outputs can be used with either balanced or
unbalanced loads, provided the proper cabling is used.
A balanced line is defined as two-conductor shielded cable with the two center conductors carrying the
same signal but of opposite polarity when referenced to ground. An unbalanced line is generally a sin-
gle-conductor shielded cable with the center conductor carrying the signal and the shield at ground
potential.

Tie pin 3 to the ground for unity gain in/out of the 1066 when using unbalanced input connections to
balanced output connections or balanced input connections to unbalanced output connections. To
do otherwise won’t hurt the unit but will result in unmatched input to output levels, and the level con-
trol will not be properly calibrated.
The following cable wiring diagrams may to assist you with input and output connections for both bal-
anced and unbalanced connectors.
