The Extron MDA 5A RCA is a compact, one input, five output stereo audio distribution amplifier. It accepts unbalanced stereo audio on one pair of RCA connectors and outputs the amplified signal on five pairs of RCA connectors.

The MDA 5A RCA is rack or under-desk mountable and comes with an external power supply. Its small size makes it the ideal solution for easy integration into both new and existing AV systems including boardrooms, training facilities, home theater, command and control centers, and rental and staging environments.

Features

• Input: One pair of female RCA connectors

• Outputs: Five pairs of female RCA connectors

• Accepts and distributes unbalanced stereo audio on RCA jacks

• Unity audio gain

• Rack, under-desk, and projector-mountable, four per rack

• External universal energy efficient power supply included, replacement part # 70-775-01 — Provides worldwide compatibility, low power consumption, and reduced operating costs.
