Configuration
• The
Output Mode
preset menu enables individual amplifier
outputs to be switched off or configured for Lo-Z or Hi-Z
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 (
Diagram 4r)
.
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.
•
Driver Alignment
in the preset menu will allow for delay to
be set between driver passbands ( Diagram 4o) .

• The
Polarity
preset menu enables the polarity of individual
amplifier outputs to be reversed ( Diagram 4p) .

• 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 (
Diagram 4q)
.
Note: In automatic mode, the peak limiter parameters adjust
automatically in response to Crossover & Gain high-pass filter
settings.
