Composite video input connectors

— Connect composite video

sources to these female BNC connectors.

The MAV 62 switchers do not alter the video signal in
any way. The signal output by the switcher is in the
same format as the input.

Connections for balanced and unbalanced audio inputs

Each input has a 3.5 mm, 5-pole captive
screw connector for balanced or
unbalanced stereo audio input.
Connectors are included with each MAV
switcher, but you must supply the audio
cable. See figure 2-4 to wire a connector
for the appropriate input type and
impedance level. High impedance is
generally over 800 ohms.

CAUTION

The captive screw connector can easily be
inadvertently plugged partially into one receptacle
and partially into an adjacent receptacle. This
misconnection could damage the audio output
circuits. Exercise care to ensure the captive screw
connector is plugged into the desired input or
output.

When making connections for the switcher from existing
audio cables, see figure 2-5. 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 2-4 and figure 2-6.

The audio level for each input can be individually set, via the
front panel or RS-232, to ensure that the level on the output does
not vary from input to input. See chapter 3, Operation, and
chapter 4, RS-232/Remote Control, for details.

Connections for audio outputs

— These 3.5 mm, 5-pole captive

screw connectors output the selected unamplified, line level
audio. Connect audio devices, such as an amplifier or powered
speakers. See figure 2-6 to properly wire an output connector.

CAUTION

Connect the sleeve to ground (Gnd). Connecting
the sleeve to a negative (-) terminal will damage the
audio output circuits.

By default, the audio output follows the video switch. Audio
breakaway, commanded via the RS-232 link, allows the user to
select from any one of the audio input sources. See chapter 4,
RS-232/Remote Control for details on the RS-232 connection
