Controls:
Gain: The gain control has a 0 to +12 dB of gain. It is used to compensate when the input level is too low. It is
recommended to keep the gain low and the input signal strong to improve Signal/Noise ratio.
Hi Response: This controls the high end roll off point of the speaker simulation. The range goes from a dark 1.5 KHz
roll off typical of subwoofers speakers, to 8 KHz, like an extended range speaker, going anything in between.
Hi Response range
Cab Size: This knob controls the theoretical size of the cabinet, as it moves the low frequency resonance up or down.
Smaller cabinets with smaller speakers tend to have a higher resonant peak than bigger stacks. The range goes from
small cabinets (1x8" style), at 180Hz up to huge 2X15" cabinet resonant frequency at 70Hz.
Cab Size Range
Resonance: This knob alters the intensity of the resonant frequency of the cabinet. Big closed back cabinets have a
very resonant peak at the low frequencies, in contrast, small open back cabinets have a mellower resonance. Note: if
the input signal contains a lot of low frequency content, maxing this control out may induce oscillation.
