Crossover
· FTRL: Choose the type of low frequency filter (high pass). Types can be Buttwrth (Butterworth), Link-
Ri (Linkwitz-Riley) or Bessel.
· FRQL: Filter cut-off frequency of low frequency crossover point (high pass). Ranges from 20 to
20,000Hz in either 1Hz steps or 1/36 octave steps. Select frequency resolution in the
System Menu
.
· SLPL: Filter Slope of low frequency crossover point (high pass). Ranges from 6 to 48dB/octave in 6dB/
octave steps. If the selected Filter Type is Linkwitz Riley, the available slopes are 12 / 24 / 36 / 48 dB/
octave.
· FTRH: Choose the type of high frequency filter (low pass). Types can be Buttwrth (Butterworth), Link-
Ri (Linkwitz-Riley) or Bessel..
· FRQH: Filter cut-off frequency of high frequency crossover point (low pass). Ranges from 20 to
20,000Hz in either 1Hz steps or 1/36 octave steps. Select frequency resolution in the
System Menu
.
· SLPH: Filter Slope of high frequency crossover point (low pass). Ranges from 6 to 48dB/octave in 6dB/
octave steps. If the selected Filter Type is Linkwitz Riley, the available slopes are 12 / 24 / 36 / 48 dB/
octave.
Compressor
· THRESH: Compressor Threshold. Ranges from -20 to +20dBu in 0.5dB steps.
· ATTACK: Attack time. Ranges from 0.3 to 1ms in 0.1ms steps; from 1 to 100ms in 1ms steps.
· RELEASE: Release time. Can be set at 2X, 4X, 8X, 16X or 32X the attack time.
· RATIO: Set compression ratio, 1:1 to 40:1 (Limit).
