Section 5: Features and Operation
5.
SPEAKER SELECT
switch – Determines which set of Speaker Outputs ("A" or
"B") are active. When the button is in the up position, speakers connected to
Output A and a connected subwoofer are active. When it is depressed (in the
down position), speakers connected to B OUTPUT SPEAKER are active.
Note: The processing functions of the MSC1 (Room Mode Correction, EQ, and
subwoofer capabilities) are only applied to "A" Speaker Outputs. Flat, unprocessed
signal is routed to the "B" Speaker Outputs.
6. INPUT SELECT switches 1 & 2 – Determine which
of the three stereo input signals (A, B, or C) is being
monitored. To monitor sources connected to inputs A
or B, make sure INPUT SELECT switch 2 is in the
UP position and then use the INPUT SELECT switch
1 to choose Input A (up) or Input B (down). To monitor
Input C, depress INPUT SELECT switch 2 . When INPUT SELECT Switch 2 is
pressed, the position of the INPUT SELECT Switch 1 has no effect.
7. INPUT TRIM Control – Can be used to add or reduce system gain once the
MSC1 VOLUME control is operating in a comfortable range. If the CLIP LED
(see #8 below) illuminates frequently or steadily, reduce the setting of the INPUT
TRIM control by turning it counter-clockwise.
When you first use the MSC1, we recommend you take a moment to set the
INPUT TRIM control using this procedure.
1. Set the INPUT TRIM control to minimum (full counter-clockwise)
2. Set the MSC1 VOLUME control to the 12:00 position.
3. Press "Play" on the device connected to the selected input ("A", "B", or "C")
4. While listening to program material, adjust the INPUT TRIM control to
achieve a comfortable listening level.
5. If the red CLIP LED illuminates, reduce the setting of the INPUT
TRIM control.
6. Listen to each connected device and adjust the INPUT TRIM control
to a setting that works best for all connected equipment. To achieve best
balance of all sources, adjust the individual output level controls on
connected equipment.
The INPUT TRIM Control can be readjusted whenever required.
