Section 4: Setting Up Your MSC1

Power Connections

Connect the MSC1 power adaptor to the POWER Connector on the
rear of the MSC1. Plug the power adaptor into a suitable available
power source. To minimize the potential for "ground-related" noise, we
recommend connecting MSC1 to the same power source as the audio
equipment and computers connected to the MSC1.

Audio Connections

The MSC1 Monitor System Controller is equipped with balanced
(1/4 inch) TRS (Tip-Ring-Sleeve) output connectors for the connection of two
stereo speaker systems (labeled "A" and "B"), plus a dedicated balanced 6.5mm
(1/4 inch) TRS connector for the connection of a subwoofer to system A.
In addition, three pairs of input connectors are provided: two pairs of balanced
6.5mm (1/4 inch) TRS connectors, labeled A and B, and one unbalanced pair
of PHONO (RCA) connectors, labeled C, allowing the MSC1 to be used with
a wide variety of professional computer audio interfaces, soundcards, mixing
consoles and audio production equipment, as well as consumer audio products
with unbalanced outputs such as personal music players, receivers and audio
visual equipment. Finally, a stereo 6.5mm (1/4 inch) stereo headphone output
with dedicated front-panel volume control allows you to send a headphone feed
to a performer or monitor audio using headphones in the control room.
.
Note: Two additional rear-panel stereo 3.5mm (1/8 inch) audio connectors, labeled
"RMC MIC IN" and "RMC MIC OUT," are used only during RMC calibration.
See page 14 in this manual for more information.
Note: To avoid audible noise, make audio connections with speakers and MSC1
powered off.
The following illustration shows various suggested MSC1 audio interconnections.
The use of balanced cabling is recommended when connecting the MSC1 to
equipment with balanced inputs and outputs as it ensures the best possible
signal-to-noise performance. Additionally, use of unbalanced cable in systems
with balanced inputs and outputs can reduce system gain by as much as 6 dB.
Confirm the settings of controls on connected speakers and subwoofer:
• Speaker and subwoofer volume controls should be set to maximum setting.
• If the Subwoofer includes a crossover control, it should be set to the highest
available frequency.
• Speaker tone controls may be used, but we recommend these are bypassed
prior to RMC calibration and restored according to taste, after RMC calibration
(See MSC1 Control Center Software User's Guide).
