AEV Matrix 212 MPX Audio Matrix – 2 In / 12 Out

Product overview

The AEV Matrix 212 MPX Audio Matrix is a 1U rackmount MPX distributor and switcher designed for facilities that need to route two composite MPX signals to up to twelve destinations. Each output can be assigned to either input A or input B, allowing broadcasters to build flexible distribution and changeover schemes for transmitters, STL paths or regional switching points. The unit is especially useful where reliable MPX redundancy and selective output assignment are required in a compact form factor.

Key features

• Two MPX inputs with twelve independent MPX outputs in a 1U 19″ chassis
• Per-output switching between input A and input B
• Individual output level adjustment from -6 dB to +6 dB
• Through function maintains signal pass-through even with power off
• Backup relay circuit supports predefined output assignment on power loss
• Remote switching control via rear-panel DB15 logic interface
• BNC connectors on floating chassis for MPX input and output paths
• Low distortion and compact power consumption for continuous service

Connectivity and I/O

The AEV Matrix 212 MPX provides two rear-panel BNC MPX inputs and twelve 50 ohm BNC outputs, allowing straightforward connection to composite MPX distribution paths. Each output can replicate either of the two source inputs, and the rear-panel DB15 remote connector allows external logic control of the switching state for individual outputs. In broadcast transmission systems it can be deployed alongside MPX distribution equipment and FM audio processors wherever flexible MPX routing or backup changeover is required.

In operation

In daily use the AEV Matrix 212 MPX gives engineers precise control over how composite MPX feeds are distributed to multiple destinations, whether for normal service, backup routing or selective regional switching. The per-output selection and level trimming simplify balancing and changeover tasks, while the through and backup functions help maintain continuity under fault or power-loss conditions. For broadcasters working with composite distribution plants, the Matrix 212 MPX provides a compact, purpose-built solution within the wider AEV broadcast range.
