Installation

2. If feet were previously installed on the bottom of the MDA, remove them.

3. For furniture mounting, hold the MDA with the attached brackets against the underside of the table or other furniture. Mark the location of the screw holes of the bracket on the mounting surface.

4. For furniture mounting, drill 3/32” (2 mm) diameter pilot holes, 1/4” (6.3 mm) deep in the mounting surface at the marked screw locations.

5. For furniture mounting, insert #8 wood screws into the four pilot holes. Tighten each screw into the mounting surface until just less than 1/4” of the screw head protrudes.

6. For furniture mounting, align the mounting screws with the slots in the brackets and place the MDA against the surface, with the screws through the bracket slots.

7. For furniture mounting, slide the receiver slightly forward or back, then tighten all four screws to secure the MDA in place.

8. For projector mounting, secure the MDA to a projector mount or other surface by inserting the mounting bolt through the bracket’s slotted hole.

Do not tin the stripped power supply leads before installing the captive screw connector. Tinned wires are not as secure in the captive screw connectors and could pull out.

The two power cord wires must be kept separate while the power supply is plugged in. Remove power before continuing.

To verify the polarity before connection, plug in the power supply with no load and check the output with a voltmeter.

Extron Electronics has long been a leader in the field of signal distribution and management technologies, and its MDA series is a testament to the company’s commitment to high-quality, versatile solutions. Among the notable models in this series are the MDA 5SV, MDA 5A RCA, and MDA 5V, each designed to cater to specific signal distribution needs while ensuring optimal performance and reliability.

The MDA 5SV is a five-output distribution amplifier that supports a wide range of video signals, including composite, S-Video, and component video. This model features state-of-the-art circuitry that minimizes signal degradation, ensuring that high-quality video is maintained even over long distances. The MDA 5SV’s robust design allows it to easily handle multiple signals without introducing noise or distortion, making it an ideal choice for classrooms, conference rooms, and other professional AV setups.

Similarly, the MDA 5A RCA model focuses on providing exceptional audio and video distribution capabilities through its five RCA outputs. This unit is particularly beneficial for systems where standardized RCA connections are preferred. It boasts a simple yet effective layout, allowing for easy integration with existing video equipment. The MDA 5A RCA ensures that video signals are distributed without loss of quality, thanks to its advanced circuitry and amplifier technologies designed to maintain signal integrity.

The MDA 5V, on the other hand, is engineered for applications that require higher resolution video signals. It supports HD video formats and provides five outputs, making it a perfect fit for modern AV environments requiring full HD distribution. Like its counterparts, the MDA 5V utilizes Extron's proprietary technology to reduce video artifacts and improve overall signal clarity, thereby enhancing the viewing experience.

Common features across the MDA series include adjustable gain controls, which allow users to fine-tune the output levels according to their specific equipment requirements. The devices also feature built-in LED indicators for easy monitoring of power and signal status. Also noteworthy is their compact design, which enables efficient integration into AV racks or setups with limited space.

In summary, Extron's MDA series, encompassing the MDA 5SV, MDA 5A RCA, and MDA 5V, represents the pinnacle of video and audio distribution solutions. With their advanced technologies and robust features, these devices ensure that professionals can achieve uncompromised signal quality across varied AV applications, making them essential tools for any advanced AV installation.
