Filter:
Select any of the five independent filters to use.
Type:
Choices are: Parametric, Notch, Allpass1, Allpass2, Horn EQ,
Parametric: Frequency, BW (in oct), Level
Notch: Frequency, BW (in oct). Notch has a fixed attenuation on minus infinity and the BW is defined 3 dB from unity.
All Pass1: Frequency
All Pass2: Frequency and Bandwidth
Horn EQ: Turnover Frequency and Level
LPF6 and HPF6: Frequency
LPF12 and HPF12: Frequency and Q
Low and High Shelf: Frequency and Level
Bandpass: Center Frequency and Bandwidth
DYNAMICS:
Inputs A and B or outputs
Threshold:
The threshold is adjustable in .5 dB steps from
Ratio:
The ratio determines how strong the limiting becomes once the threshold is crossed. Values of 1:1 (no compression) to 20:1 are possible. Ratios of 10:1 and above should be selected for speaker protection.
Attack:
The attack function sets the amount of time for the compressor to respond once the threshold has been crossed. Specifying this value allows the user to determine whether the compressor responds as a peak or RMS unit as very short attack times consider only peaks while times above 50 ms average these peaks and result in RMS response. We recommend attack times of between 50 ms - 100 ms be used when setting the limiters to protect the speakers from being overdriven by the power amps. It is the average power long term that causes speaker burn out. The transient peaks usually cause little damage if kept inside the speaker’s band limits.
