Detailed Parameters

 

 

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 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®
