• The
Driver Alignment
preset menu enables delay to be
applied to individual amplifier outputs.
• The
Polarity
preset menu enables the polarity of individual
amplifier outputs to be reversed.
• The
Limiter
preset menu enables signal limiting to be
applied to individual amplifier 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 filter
settings.
• The
Output Mode
preset menu enables individual amplifier
outputs to be switched off or configured for Lo-Z, Hi-Z or
Lo-Z BTL modes. In Hi-Z modes, a high-pass filter can also
be configured and applied to the output. The number of
outputs available will depend on the amplifier model, input
setup and zone setup. For example, a two output amplifier
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 amplifier output
channels are combined to create a single, double power output
channel.
Note: Use of a high-pass filter with Hi-Z mode loudspeakers is useful
to avoid the possibility of distortion caused by low frequency line
transformer saturation. Begin with the default filter 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.
