Section 5: Features and Operation
Note: If the Subwoofer has Left and Right inputs, connect the MSC1 SUB "A" Output
to either the Left or Right Subwoofer input. Set the Subwoofer crossover control to the
highest available frequency. If the Subwoofer has a LFE (Low-Frequency Effects) input
or a direct input, connect the MSC1 SUB "A" output to this input. The SUBWOOFER
OUTPUT is derived from the sum of the Left and Right "A" SPEAKER OUTPUTS.
5. INPUTS ("A", "B", and "C") – Allow connection of up to three signal sources:
two pairs of balanced 6.5mm (1/4 inch) TRS connectors, labeled A and B,
for the connection of professional (+4 dBu) equipment, plus one unbalanced
pair of PHONO (RCA) connectors, labeled C, for the connection of consumer
(-10 dBV) equipment.
6. HEADPHONE OUTPUT – Connect a standard pair of stereo headphones to
this 6.5mm (1/4 inch) stereo jack for private monitoring of the MSC1 output.
Note: For private monitoring of the MSC1 signal over headphones with all speakers off,
turn the main MSC1 VOLUME control to its fully counterclockwise ("-∞") position and
use the dedicated HEADPHONE VOLUME control to set the desired listening level.
7. RMC MIC IN – Connect the supplied microphone here when performing an
RMC calibration. For more information, see the MSC1 Control Center Software
User's Guide.
8. RMC MIC OUT – Used to connect your MSC1 to the audio input of your
computer's audio interface or soundcard when performing an RMC calibration.
For more information, see the MSC1 Control Center Software User's Guide.
9. LEVEL PAD – When depressed, increases the level of the signal being sent
from the RMC MIC OUT jack (see #8 above) by 8 dB. For more information,
