Section 5: Features and Operation
11. SUB ON control – If a subwoofer is connected to the SUB Output "A", and
the "A" speakers are being monitored, this control allows you to quickly
and easily listen to "A" speakers with and without a subwoofer. When the
subwoofer is included in the system, Bass Management Crossover filters
are applied that route low frequency signals below the crossover frequency
to the subwoofer and signals above the crossover frequency to the Left
and Right speakers. When the SUB control is illuminated, the subwoofer
is heard. When the control is not illuminated, the subwoofer is muted and
the Left and Right speakers play a full range signal. Subwoofer Level and
Bass Management crossover are set using MSC1 Control Center software.
Three Bass Management crossover frequencies are provided and the MSC1
ships with an 80 Hz Bass Management crossover selected and subwoofer
gain set to 0 dB (no additional boost or attenuation). (See the MSC1 Control
Center Software User's Guide.)
Note: If your subwoofer has a crossover frequency control, the control should be set to
the highest available frequency.
Note: The SUB control will flash repeatedly instead of illuminating steadily when
Speaker Output B is selected because a connected subwoofer can be heard only when
Speaker Output A is selected
12. MUTE control – When illuminated, mutes all output signal from the MSC1,
including the headphone output.
