TUNABLE SPKR 2
Tunable Spkr 2 is similar to Tunable Spkr 1, offering an EQ controllable speaker sound, but with
a warmer, “analog” sound. By tuning three parametric filters, you can simulate many different
speaker cabinet sounds that are used in all styles of music.

01 — Mix
02 — Volume
See the descriptions under the Mix and Volume Parameters, in the beginning of this section.
03 — Mid1 Fc Range: 100 to 9999 Hz
Sets the center of the mid-frequency parametric. Higher values have a brighter sound.
04 — Mid1 Gain Range: -48 to +24 dB
Sets the amount of cut (negative values) or boost (positive values) applied to this mid-frequency
parametric.
05 — Mid1 Q Range: 01 to 18
This parameter is a bandwidth control that determines the width of the resonant peak at the
center of the frequency band. By raising the value, you can produce a narrower bandwidth.
06 — Mid2 Fc 09 — Mid3 Fc
07 — Mid2 Gain 10 — Mid3 Gain
08 — Mid2 Q 11 — Mid3 Q
These parameters are identical to the previous ones, but can be assigned to control different
bandwidths within the mid-range.
12 — PreEQ InputLevel Trim Range: -18 to +06 dB
This parameter allows you to adjust the input level before the EQs to eliminate the possibility of
clipping boosted signals.
13 — Speaker Output Gain Range: -48 to +24 dB
Since speaker cabinets are “lossy,” output gain is required to compensate losses in perceived
volume. Setting this gain too high will cause clipping of the output signal.
14 — Noise Gate Off Below Range: -96 to +00 dB
This parameter sets the threshold level at which the noise gate shuts off the audio.
