Extron electronics AVDA 6 MX DUAL User Manual page 2

Models and Features
Extron's Audio/Video
Distribution Amplifier models
include two or more of the
features listed at the top of the
table to the right. A "•",
2 or 4 is used in the table to
indicate which features apply
to a particular model and how
many, if more than one. For
example, the model SVDA 6
MX DUAL has 2 - one input,
six output stereo audio
distribution amplifiers. All
models are housed in metal
enclosures and include 100-240 volt universal switchable power supplies.
Installing Captive Screw type Audio Connectors
Three methods of wiring the audio connectors for input and output are listed and shown
below. Input examples are across the top, output examples are below them.
• Unbalanced High Impedance (High Z) Stereo Tip, Ring, Ground (Left & Right)
• Balanced High Impedance (High Z) Stereo Tip, Ring (Left & Right)
• Balanced 600 ý input Impedance Stereo Tip, Ring (Left & Right)

Tip
Use the picture to the left when making connections for the Audio Distribu-
Sleeve
tion Amplifier from existing audio cables. The round audio connectors are
shown with the top one (tip and sleeve only) for unbalanced audio and the
Tip (+)
Ring (-)
bottom one (tip, ring and sleeve) for balanced audio. The "ring", "tip" and
"sleeve" markings are also used on the captive screw audio connector
Sleeve
diagrams above. Together, these examples may be used as a guide for
making audio cables.
___ If using the Unbalanced Output example shown above (shaded
background), connect the sleeve(s) to Ground (Gnd).
Connecting it to a negative (-) terminal will damage audio
output circuits.
___ There is no physical way to prevent you from plugging an
audio connector part in one channel and part in the adjacent
channel. This could cause damage.
_ Use captive-screw audio connectors shown here. Additional
connectors may be ordered from Extron.

Operation and Installation
Rack-Mounting the Audio/Video Distribution Amplifier (A/V DA)
To rack-mount the A/V DA use the Rack-Mount Diagram below and do the following:
1. Remove feet from the case if previously installed.
2. Mount the A/V DA on the rack shelf (A) using two 4-40 x 1/8" screws in opposite
corners (under the shelf) to secure the case to the shelf. Use holes E1 and E2 or F1
and E3 for a half width case (C), E1 and E3 for a full width case (B). If necessary, use
filler panel D with front two screw holes (F1 and F2).
