Flatten/Restore
This parameter either flattens the PEQ or restores the PEQ to its original shape.
Type
This parameter selects the PEQ type. Types include: 1. Bell-All parametrics are bell-shaped
2. HShelf - One shelf is High, while all others are bell 3. LShelf - One shelf is Low, while all
others are bell and 4. LHShelf - One shelf is High and one is Low, and the others are bell.
Band (1-3) Frequency 20Hz to 20kHz
Selects the frequency of the selected band of the parametric EQ.
Level (1-3) -12dB to 12dB
Sets the boost or cut level of the selected parametric EQ.
Q (1-3) 0.20 to 16 dB
Sets the Q or Bandwidth of the selected Parametric EQ.
5.6 Compressor/Limiter
The DriveRack® PA+ also offers Compression and Limiter modules. The Compressor is a full
bandwidth Stereo Compressor located prior to the Crossover. The Compressor is the perfect
tool for tightening uneven signal sources such as vocals and guitars. The Limiters are located
on each stereo output channel and have been strategically placed for speaker and amplifier
protection. Note that Compressor/Limiter threshold metering can be observed on page two
of the Utility section. The parameters for the Compressor/Limiter are as follows and are user
adjustable.

Compressor On/Off
Turns the Compressor module on and off.
OverEasy (O) Off to 10
There are ten levels of OverEasy® that can be used for the limiters. The point when the
compressor starts to compress is the “knee.” When the compressor starts to reduce the level
of a signal abruptly as it passes over the threshold, this is called “hard knee” compression.
OverEasy (soft knee as it is sometimes called) is when the volume of the sound is compressed
gradually. OverEasy compression starts to compress before the level of the signal reaches
the threshold and reaches full compression after the level has gone above the threshold.
OverEasy compression, by its very nature, sounds much smoother and more natural and will be
used for most applications. When it is gentle (natural sounding or light) compression that you
are looking for, the compressor offers VariKnee™. VariKnee gives you ten levels of OverEasy
compression to choose from (1 being almost hard knee and 10 being the most OverEasy). This
lets you choose the exact knee that is needed for the dynamic effect you are looking for.
Threshold (T) -40 to +20dBu
Threshold is the signal level at which the unit starts to compress the signal. If the level is
set to -10 dBu, than any signal greater than -10 dBu is compressed while any signal that has
