2-6 CrossPoint 450 Plus and MAV Plus Switchers • Installation
The captive screw audio connector can easily be inadvertently plugged
partially into one receptacle and partially into an adjacent receptacle. This
misconnection could damage the audio circuits. Ensure that the connector
is plugged fully and only into the desired input or output.
• If the stripped section of wire is longer than 3/16 inch, the exposed wires may
touch, causing a short circuit between them.
• If the stripped section of wire is shorter than 3/16 inch, wires can be easily
pulled out even if tightly fastened by the captive screws.
connections for the switcher from existing audio cables. A mono audio connector
consists of the tip and sleeve. A stereo audio connector consists of the tip, ring
and sleeve. The ring, tip, and sleeve wires are also shown on the captive screw
audio connector diagrams: figure 2-3, figure 2-4, figure 2-6, and figure 2-7.

The audio level for each input can be individually set via the front panel or
via Ethernet or RS-232/RS-422 control to ensure that the level on the output
does not vary from input to input. See chapter 3, "Operation", chapter 4,
"Programmer's Guide", chapter 5, "Matrix Software", and chapter 6, "HTML
Operation" for details.
Connections for balanced and unbalanced audio outputs — These 3.5 mm,
5-pole (stereo audio BMEs) or 3-pole (mono audio BMEs) captive screw
connectors output the selected unamplified, line level audio. Connect audio
devices, such as an audio amplifier or powered speakers.
See figure 2-6 to properly wire an output connector for the stereo audio BME.

For unbalanced audio, connect the sleeve(s) to the ground contact. DO
NOT connect the sleeve(s) to the negative (-) contacts).
