Section 4
Type 4 - Butterworth (BW), Bessel (BS) and Linkwitz-Riley(L-R)
Selects the desired crossover filter type.
Low Slope 4 - 6-24dB/Octave (BW, Bessel) 12-24dB/Octave (L-R)
Sets the Lowpass slope of the crossover filter.
High Slope 4 - 6-24dB/Octave (BW, Bessel) 12-24dB/Octave (L-R)
Sets the Highpass slope of the crossover filter.
In addition to the pre-crossover EQ options within the signal path, the 240 and 241 DriveRack™
units also offer a 4-band parametric EQ after the crossover section. The parameters for the Post-
crossover EQ are as follows and are user adjustable:
PEQ On/Off (per crossover band)
Turns the PEQ band on and off per XOVER band.
The following figure shows the constant Q parametric filter.
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. L-Bell/H-Bell 2. L-Bell/H-Shelf 3. L-
Shelf/H-Bell and L-Shelf/H-Shelf.
Band (1-4) Frequency 20 to 20k
Selects the frequency of the selected band of the parametric EQ.
Q/S (1,4) 0.2 to 16.0 (bell) or 3 to 12 (shelf)
Adjusts the Q/S of the selected band of the parametric EQ. This parameter is only used in out-
puts 1 and 4.
Q (2-3) 0.20 to 16 dB
Sets the Q for outputs 2 and 3.
The 240 and 241 DriveRack™ units also offer compressing or limiting capabilities. Furthermore,
within the configuration menu, compression or limiting can be assigned to similar bands (ie:
highs with highs or lows with lows). The parameters for the Compressor/Limiter are as follows
and are user adjustable:
4.7 Compressor/Limiter (DYN)
4.6 Post-CROSSOVER PEQ (EQ)
