Connecting to an External Meyer Sound Power Supply
In this section:

UP-4slim loudspeakers require an external Meyer Sound IntelligentDC power supply. The MPS-488HPP is a 19-inch (1RU) unit that distributes DC power and balanced audio to UP-4slim speakers or other Meyer Sound IntelligentDC loudspeakers. Composite multi-conductor cables (e.g., Belden® 1502) can deliver both DC power and balanced audio. The MPS-488HP can connect to Meyer Sound’s RMS remote monitoring system. The MPS-488HP receives eight channels of balanced audio from its XLR female Channel Inputs. It routes the audio, along with 48 V of DC power, to its eight Channel Outputs. The MPS-488HP can drive up to eight UP-4slim loudspeakers.

The MPS-482HP is a 1RU, half-rack-width unit with two input channels and two output channels that is ideal for applications requiring a small channel count.

To connect UP-4slim loudspeakers to the MPS-488HP, use Phoenix 5-pin male to Phoenix 5-pin female cables.

Tip

See meyersound.com for more details about Meyer Sound IntelligentDC power supplies.

Cable lengths up to 150 feet for DC power are possible when using 18-AWG wire, with just 1 dB of loss in peak SPL. Longer cable runs are possible for moderate applications that do not drive the loudspeakers to maximum output, or for installations with heavier gauge wires. The use of composite multiconductor cables (such as Belden 1502 or equivalent) allows a single cable to carry both DC power and balanced audio to the UP-4slims.

Procedure. To connect UP-4slim loudspeakers to an MPS-488HP:

  1. Power off the MPS-488HP.

  2. Use balanced XLR cables to connect audio sources from a mixer or processor to the MPS-488HP Channel Inputs.

  3. Use the MPS-488HP Link switches to route Channel Inputs to the desired Channel Outputs.

    Tip

    See the MPS-488HP Operating Instructions.

  4. Connect the UP-4slim loudspeakers to the MPS-488HP Channel Outputs, as shown in the figure below.

    Use composite cables (such as Belden 1502 or equivalent) wired for both DC power and balanced audio and outfitted with the appropriate connectors.

    Tip

    It is possible to use a 2-conductor cable for DC power and a 3-conductor cable for balanced audio with both cables attached to a single Phoenix connector on each end. This approach supports use of a larger gauge DC cable, which allows longer cable runs (see Long Cable Runs with Separate Cable for DC Power and Audio).

    Caution

    Make sure UP-4slim loudspeaker cables are wired correctly. For details about assembling loudspeaker cables, see Phoenix Cable Assembly.

  5. Power on the MPS-488HP and monitor the LEDs on the front panel to verify connections. For information about the MPS-488HP LEDs, refer to the MPS-488HP Operating Instructions.

  6. Check the LEDs on the UP-4slim rear panels and verify they are green (ready to reproduce audio).

  7. Enable output from the audio sources (from the mixer or processor) connected to the MPS-488HP.
