5.
Connect a balanced or unbalanced analog audio output device (such as a DSP device or an amplifier) to the 5-pole captive
screw Audio Out connector (see
figure 1 , K on the previous page) for 2-Ch audio from the selected input. This connector is
configurable via VCS or SIS as two discrete mono outputs or as one stereo output (see “Audio Wiring” for details).
6.
If the MGP 641 will be connected to a computer or to a host controller for remote control, connect an RS-232 cable from
the host to the Tx, Rx, and G pins (the remaining two pins are not used) of the 5-pole Remote RS-232 rear panel connector
(see
figure 1
,
L
), or to the front panel USB mini-B Config port (see figure 2,
A
). The default protocol for the RS-232 port is
9600 baud, 1 stop bit, no parity, and 8 data bits, with no flow control.
Alternatively, connect an RJ-45 network cable to the rear panel LAN port for remote configuration and control.
7.
Connect power to the MGP by plugging a standard IEC power cord (provided) from a 100 to 240 VAC, 50-60 Hz power
source into the AC power connector (see
figure 1
,
A
).
8.
Apply power to all other devices.
Audio Wiring
Wire the audio output connectors as
shown at right. Use the supplied tie wrap
to strap the audio cable to the extended
tail of the connector.
ATTENTION:
•
For unbalanced outputs, do not connect wires to the “-” poles.
•
Pour les sorties asymétriques, ne connectez pas de câbles aux pôles « - » .
NOTE: The length of exposed wires is important. The ideal length is 3/16 inch (5 mm).
