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.

W These instructions provide a quick setup guide for experienced installers.

Installation and service must be performed by authorized personnel only.

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.

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

at right).

C 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 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.

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).
