oct-3oct@stepover is 0.01oct Gain: 20dB-+20dB@stepover 0.1dB
Functional of output channels
Output mute Each channel has independent mute control
Output selection Each output channel can be selected to be each input channel
Output gain Adjustable range:-60dB-+12dB, stepover 0.1dB
Output delay Each channel has independent delay control Range: 0-1000ms stepover 21us@<10ms; stepover 84us@10-20ms; stepover: 0.5ms@>20ms
Output polarity Same phase + or reversed phase-
Crossover Each channel can be set up LPF and HPF independently. Adjustable parameters:Filter types (Linkwitz-Rily/Besse/Butterworth)Frequency turning point: 20Hz-20KHz, 239 frequency point
Decay of slope: 12dB/oct, 18dB/oct, 24dB/oct, 48dB/oct
Limiter Each channel can be set up limiter indenpendently. Adjustable
parameters: Threshold value: -20dBu-+20dBu. Stepover:
0.5dBu@starting time: 0.3ms-100ms. Stepover<1ms @0.1ms,stepover>1ms@1ms
Output EQ Each output channel can be set up 15 Bands EQ. Both EQ modes,PEQ & GEQ are available. When set as PEQ the adjustable paremeters: LQ-EQ 1 (bass boost or low cut), H1-EQ15 (High boost
or High damp) are the frequency point adjustable filiter, S-dB can
choose 6dB/oct or 12dB/oct. Gain: -40dB-+20dB. Stepover: 0.1dB,
other are 13 Bands parametric EQ. Central frequency point: 20Hz-20
KHz, 239 frequency point totally. Band width: 0.01oct/3oct, stepover
is 0.01oct. When set as GEQ the function are the same as when set as PEQ. Only the frequency
Gain increased Each channel has independent Gain control from -60dB to +12dB
