Detailed Parameters
Section 4
Flatten/Restore
This parameter either flattens the PEQ or restores the PEQ to its original shape.
Type
This parameter selects the PEQ band type. Types include:
• Bell - All bands are bell-shaped.
• HShelf - One band is a high shelf, while all others are bell.
• LShelf - One band is a low shelf, while all others are bell.
• LHShelf - One band is a low shelf, one is a high shelf, and all 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 level (gain) of the selected parametric EQ.
Q (1-4) 0.20 to 16 dB
Sets the Q or Bandwidth of the selected Parametric EQ.
The following figure shows the constant Q parametric filter.
S (1 and 4, shelf type filters only) 3, 4.5, 6, 9, and 12 dB/Octave
Sets the slope rate when using a low or high shelf type filter.
4.9 Compressor/Limiter
The DriveRack 260 also offers Compression and Limiting 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,
providing a more even mix. The Limiters are located
on each output channel and have been strategically placed for speaker and amplifier protection. 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 follows 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 compressor. 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
