Chapter 8: dbx 160 Compressor/Limiter

dbx 160 Controls

The minimal controls on the UAD dbx 160 make it very simple to operate.

Threshold

Knob

The Threshold knob defines the level at which the onset of
compression occurs. Incoming signals that exceed the
Threshold level are compressed. Signals below the Thresh-
old are unaffected.

The available range is from –55 dB to 0 dB. The numbers on the graphical in-
terface indicate volts, as on the original hardware.

As the Threshold control is decreased and more compression occurs, output
level is typically reduced. Adjust the Output Gain control to increase the out-
put to compensate if desired.

Below

When the input signal is below the compression threshold value, the Below
LED illuminates. No compression is occurring when Below is lit.

Above

The Above LED illuminates when the input signal has exceeded the Threshold
value, indicating that compression is occurring. The higher the signal is above
the Threshold, the brighter the LED glows.

Compression

The Compression parameter determines the ratio for the
compressor. Less compression occurs at lower values. The
available range is continuous, from 1.00:1 to Infinity:1.

Note:

For compression to occur, signals must exceed the

Threshold value.

At values above approximately 10:1, the compressor behaves more like a
peak-limiter. See

“The LA-2 captures one of the earliest Teletronix examples.

This exceedingly rare unit preceded the LA-2A by a few years and incredibly,
still has the original T4A fully intact. The LA-2 provides the slowest response
and a unique “mellowed” sound due to 50 years of luminescent panel aging
