Setup Guide — MDA 5V, 5SV, 5A RCA

The Extron® MDA 5 series of mini distribution amplifiers distribute buffered
composite video (MDA 5V), buffered S-video (MDA 5SV), and amplified stereo audio
(MDA 5A RCA). Unless otherwise stated, these instructions apply to all three of the
amplifiers.

Step 1

Turn all the equipment off and disconnect all cables.

Step 2

Mount the unit in a convenient location, in a rack, under a desk, or on a projector mounting system. Follow the
instructions included with the appropriate mounting kit.

Step 3

Connect the external 12 VDC power supply (provided) to the 2-pole, captive screw power
connector (b). When power is applied to the unit, the front panel LED (a) lights green.

Step 4

For the MDA 5V:

Connect a video source to the video input (c), using composite video (BNC) connectors.

For the MDA 5SV:

Connect a video source to the video input (c), using S-video (4-pin mini DIN) connectors.

For the MDA 5A RCA:

Connect an audio source to the audio inputs (c), using unbalanced stereo to RCA connectors. Left channel input goes to
the upper input; right channel input goes to the lower input.

Voltage polarity is important. Identify the negative lead by the ridges on the side (see figure

at right).

Always use a power supply specified by Extron for this unit. Use of an unauthorized power

supply voids all regulatory compliance certification and may cause damage to the supply
and the distribution amplifier.

Step 5 (optional)

For the MDA 5V:

Connect the video loop feed (d) to a local monitor, using composite video connectors.

For the MDA 5SV:

Connect a video loop feed (d) to a local monitor, using S-video connectors.

Step 6

For the MDA 5V and MDA 5SV models:

If a terminated device was connected to the loop feed in step 5, set the High Z/75 Ohm switch (f) to High Z (up
position, as shown in the figure at right). If no device or an unterminated device was connected to the loop feed
in step 5, set the switch to 75 Ohm (down position).

Step 7

For the MDA 5V:

Connect up to five display composite video devices to the outputs (g), using composite video connectors.

For the MDA 5SV:

Connect up to five display S-video devices to the outputs (g), using S-video connectors.

For the MDA 5A RCA:

Connect up to five stereo audio devices to the audio outputs (h), using the RCA connectors (left channel top; right channel
bottom).
