MEYER SOUND MPS-488e Power Supply (48V DC)

The Meyer Sound MPS-488e external power supply delivers DC power and balanced audio to up to eight Meyer Sound MM-4XP loudspeakers. The single-space 19-inch rack MPS-488e receives eight channels of balanced audio from its XLR female input connectors and routes the audio, along with 48 V of DC power, to its eight output connectors. Input channels feature toggle switches that route inputs to corresponding channel outputs only, or to adjacent, contiguous channel outputs. For example, channel input 1 could be routed to channel outputs 1 and 2 and channel input 3 could be routed to channel outputs 3 and 4. Another example would be to route channel input 1 to channel outputs 1–4 and channel input 5 to channel outputs 5–8. The power supply's eight channel outputs are available as either 5-pin Phoenix connectors on the Meyer Sound MPS-488p model, or 5-pin SwitchCraft EN3 connectors on the Meyer Sound MPS-488e model.

The Meyer Sound MPS-488e front panel has two LEDs per output channel that provide useful feedback on the status of the system. The voltage LEDs indicate when voltage is present for each output channel. The load current LEDs indicate when a loudspeaker is connected to an output channel and glow brighter as the signal level increases.
