Note

For information about cable requirements for loudspeakers, refer to their operating instructions. For information about cables and cable accessories available from Meyer Sound, see MPS-482HP Power Supply Cable Accesories.

Caution

Make sure loudspeaker cables are wired correctly. For details about assembling loudspeaker cables, refer to Assembling Loudspeaker Cables.

Procedure. To power loudspeakers with the MPS-482HP Power Supply:

  1. Power off the MPS-482HP Power Supply.

  2. Connect audio sources (from a mixer or processor) to the MPS-482HP Power Supply channel inputs. Use balanced XLR cables or a 3-conductor cable for balanced audio fitted into a 6-pin Phoenix connector.

  3. Use the MPS-482HP Power Supply Link switch to route input 1 to one or both channel outputs (see Link Switch).

  4. Connect the loudspeakers to the MPS-482HP Power Supply channel outputs. Use composite cables (such as Belden 1502 or equivalent) wired for both DC power and balanced audio and outfitted with the appropriate connectors.

    • When connecting loudspeakers equipped with Phoenix connectors to the MPS-482HP Power Supply, use Phoenix 5-pin female to Phoenix 5-pin female cables.

    Tip

    With the MPS-482HP Power Supply, using two separate cables for loudspeaker connections is also possible: a two-conductor cable for DC power and a three-conductor cable for balanced audio, both attached to a single Phoenix connector on each cable end. This approach enables use of larger gauge wires for the DC cable to achieve longer cable runs.

    Note

    HMS-15 loudspeakers require power from both channels of the MPS-482HP Power Supply. If audio signal is present on both channels connected to an HMS-15, the signal is summed internally.

    When connecting loudspeakers equipped with ECO-M connectors to the MPS-482HP Power Supply, use Phoenix 5-pin female to ECO-M 7-pin female cables.

  5. Power on the MPS-482HP Power Supply and monitor the LEDs on its front panel to verify the connections (see Fuse, Voltage, and Load Current LEDs (1–2).

  6. Check loudspeaker LEDs to determine whether the loudspeakers are ready to reproduce audio.

  7. Enable output from the audio source (from a mixer or processor) connected to the MPS-482HP Power Supply.
