The Gate/Expander
Typically, a gate is used to turn off a channel when there is no signal to reduce the
overall noise level of the mix. When the signal drops below a certain level determined
by the threshold control, it is turned off. When the signal comes back up and crosses the
threshold, the level returns to normal. One problem with using a gate is that if the threshold
is set too low, ambient sounds will cause the gate to turn on and off, which can be audible,
and if the threshold is set too high, as a sound fades it will suddenly drop out, resulting in an
unatural fade.
Downward expansion can help solve this problem. When the signal level falls below the
threshold, it is slightly attenuated. The further the signal falls below the threshold, the more
it is attenuated. The expander in the SQ•2 automatically adjusts the ratio of the expansion
based on the type of program that it sees.
The Squeez Series™ of processors are powerful and tough. They are designed to
withstand the punishing rigors of the road and continue to perform day after day, year
after year.
Here’s a quick glance at the features packed into the SQ•2:
• 2-channel compressor/gate with smooth, musical sound
• Automatic Soft Knee/Hard Knee curves depending on the compression setting
• Adjustable AIR Filter to enhance the high frequencies after compression
• Soft Gate/Expander for imperceptible gating
• Individual Threshold, Ratio, Attack, and Release controls on each channel
• Output gain compensation control on each channel to add gain back to the compressed signal
• Auto Attack/Release button with indicator on each channel
• Individual IN/OUT button with indicator for each channel
• Precision 8-segment gain reduction meters
• Balanced/unbalanced 1/4" TRS and XLR line input and output jacks
• Side Chain connections
• Selectable line voltage
