Speaker Preset parameter adjustment
• The Driver Alignment preset menu enables delay to be
applied to individual amplier outputs.
• The Polarity preset menu enables the polarity of individual
amplier outputs to be reversed.
• The Limiter preset menu enables signal limiting to be
applied to individual amplier outputs. Clip limiting, peak
limiting and RMS limiting can be individually or collectively
engaged. The Peak limiter can be set to either automatic
or custom parameter values. The RMS limiter has default
parameter values that can be adjusted but has no automatic
option.
Note: In automatic mode, the peak limiter parameters adjust
automatically in response to Crossover & Gain high-pass lter
settings.
• The Output Mode preset menu enables individual amplier
outputs to be switched off or congured for Lo-Z, Hi-Z or
Lo-Z BTL modes. In Hi-Z modes, a high-pass lter can also
be congured and applied to the output. The number of
outputs available will depend on the amplier model, input
setup and zone setup. For example, a two output amplier
will have two outputs available if Lo-Z mode is selected but
only one output available if Hi-Z mode is selected.
Note: In Lo-Z BTL (bridge-tied load) mode, two amplier output
channels are combined to create a single, double power output
channel.
Note: Use of a high-pass lter with Hi-Z mode loudspeakers is useful
to avoid the possibility of distortion caused by low frequency line
transformer saturation. Begin with the default lter setting of 70Hz.
If low frequency distortion is still audible, increase the frequency
setting one step at a time until the distortion is no longer audible.
