Home Theatre (HT) Mode
Enable HT Mode to set a separate gain setting for a selected input. The HT mode of
each input is saved in non volatile memory so even after a power outage this
programming is stored inside the preamplifier. Each time that source is selected the
level will jump to the programmed level and you use the HT processors level control to
set the volume - which also controls the other channels such as rear channels, etc...
If your HT processor already had its levels set for the same amplifiers directly
connected to the HT Processor then using level 24 (unity gain) on the preamplifier will
maintain proper surround channel vs main channel levels. If you are installing a new
processor or making other changes in the system then you should set the preamplifier
to an HT mode for that processor input BEFORE you set your surround levels. That way
the system levels will be correct each time that input is selected. The volume could
simply be set manually to the desired level each time you use that input. The HT
feature is just a handy way to make the level jump automatically to the same volume
each time that input is selected.
NOTE: In some systems switching to an unused input will cause a small amount of hum
at the speakers. This is because with no input connected the signal path is ’hanging in
the breeze’ picking up whatever noise is floating by. For unused inputs HT mode can
be engaged and set to volume level 1 or mute. Then when selected the level is so low
that there will be no hum.
Tape Loop
After connecting a tape deck or a digital processor to the Tape inputs and outputs,
enable the Tape Loop feature and select the type of device you’re using in the
settings (TAPE for analog and PROCESSOR for digital).
Output Settings
Use this function to offset the sensitivity of your outputs - generally used for bi-amping
purposes.
Input Settings
Use this function to offset the sensitivity of your Inputs and maintain an
equal gain level from all your sources.
System Settings
Date & Clock - set the correct time & date
Display - set display brightness and customize the interval the device would be
inactive before the display dims (0-60s).
