connectors. Left and right audio can use the R and B BNC connectors shown to
the left (labeled R Audio and L Audio). Audio can also use the 6-pin Phoenix®
brand of captive screw connector shown at the bottom of each input and output.
Audio connections can be made using the Phoenix
terminals in the following ways:
• Unbalanced High Impedance Stereo Tip, Ring, Ground
(Left & Right)
• Balanced High Impedance Stereo Tip, Ring (Left &
Right)
• Balanced 600 ohm Impedance Stereo Tip, Ring (Left &
Right)
Right and left audio ports are available on both BNC connectors and on
6-terminal screw Phoenix connectors. BNC audio outputs are available only
when using Composite Video or S-Video sources. When using the BNC input
ports for audio, any unselected audio port will be terminated at 75 ohms. Verify
that this termination will not damage the output.
An audio level attenuator is located to the right of each bottom BNC input
channel connector. The attenuators are used to adjust only the audio levels
going to the Phoenix connector output, and not those going to the BNC outputs.
Because attenuators can only decrease (not increase) the audio levels, initial
adjustments should be made with the attenuators set to the maximum
(clockwise) position.
The captive connectors are located on the rear panel, just below the BNC
connectors, and are labeled "R" (right) and "L" (left) for each channel. When
wiring these Phoenix connectors and inserting them into the System 8/10 P
switcher, remember that the screw heads must face downward. Use the
following diagrams to wire the connectors for your audio inputs and outputs.
