Outputs Setup Menu
The Outputs Setup Menu provides the ability to
change how the C2800 Output 1, Output 2 and
Headphones function.
Output Mode
The Outputs on the C2800 can be independently
congured to operate in one of several modes.
• Switched (Default) - The Output is set to allow
toggling by using the Front Panel OUTPUT 1
and 2 Buttons, or by using the OUTPUT 1 and
2 Buttons on the Remote Control.
• Unswitched - The Output is set to On, and
toggling is disabled.
• Bi-Amped (Fixed) - This mode is a variant of
Unswitched that is exclusive to Output 1 and
enables the Bi-Amp Circuitry in Fixed Mode.
• Bi-Amped (Split) - This mode is the same as
Bi-Amped (Fixed) but Bi-Amp Circuitry is in
Split Mode.
Output Trim Level
Adjusts the level of Output 1 relative to the Main
Output. This setting is always active, and is useful
for bi-amping.
Bi-Amp Circuitry
The C2800 has internal, adjustable crossover. The
C2800’s crossover tailors the output frequency
range of each amplier section to the attached
loudspeaker. In Fixed Mode, simply set the
Center to the loudspeaker’s Crossover Point, then
frequencies above the Crossover Point will be
sent to the MAIN Output and frequencies below
the Crossover Point will be sent to Output 1. In
Split Mode, the lter’s corner frequencies can be
independently congured. As an example, the
High Pass Outputs could be sent to a vacuum tube
amplier, and the Low Pass Outputs could be sent
to a solid-state amplier. This adjustable crossover
allows you to optimize the performance of your
ampliers to your speaker’s specications and
to your listening preferences. A direct feed can
also be connected to each amplier section, thus
bypassing the internal crossover.
