Detailed Parameters
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 oth-
ers are bell and 4. LHShelf - One shelf is High and one is Low, and the others are bell.
Band (1-4) Frequency 20Hz to 20kHz
Selects the frequency of the selected band of the parametric EQ.
Level (1-4) -12dB to 12dB
Sets the peak level of the selected parametric EQ.
Q (1-4) 0.20 to 16 dB
Sets the Q or Bandwidth of the selected Parametric EQ.
The 260 DriveRack also offers Compression and Limiter modules. The Compressor is a full
bandwidth Stereo Compressor inserted 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 output channel and have been strategically placed for speaker and amplifier protec-
tion. Note that Compressor/Limiter threshold metering can be observed in the Meter section by
pressing and holding the Utility button. The parameters for the Compressor/Limiter are as fol-
lows and are user adjustable.
COMPRESSOR
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 com-
pressor 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.
