CHAPTER 3: POWERING LOUDSPEAKERS WITH THE MPS-482HP
NOTE:
For information about cable
requirements for your loudspeaker, refer to its
operating instructions. For information about cables
and cable accessories available from Meyer Sound,
see Appendix A, "MPS-482HP Cable Accessories."
For information about cable assembly, refer to
Appendix B, "Assembling Loudspeaker Cables."
CAUTION:
Make sure loudspeaker cables are
wired correctly. For details about assembling
loudspeaker cables, refer to Appendix B, "Assembling
Loudspeaker Cables."
To power loudspeakers with the MPS-482HP:
1. Power off the MPS-482HP.
2. Connect audio sources (from a mixer or processor) to
the MPS-482HP channel inputs. Use balanced XLR
cables or a 3-conductor cable for balanced audio fitted
into the 6-pin Phoenix connector.
3. Use the MPS-482HP Link switch to route channel inputs
to the desired channel outputs (see "Link Switch" on
page 12).
4. Connect the loudspeakers to the MPS-482HP 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, you can use two
separate cables for loudspeaker connections: a
2-conductor cable for DC power and a 3-conductor
cable for balanced audio, both attached to a single
Phoenix connector on each cable end. This approach
allows you to use a larger gauge for the DC cable so
you can achieve longer cable runs.
Phoenix Connector with Separate Cables
NOTE:
HMS-15 loudspeakers require power
from both channels of the MPS-482HP. 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.
CAUTION:
Make sure loudspeaker cables are
wired correctly. For details about assembling
loudspeaker cables, refer to Appendix B,
"Assembling Loudspeaker Cables."
5. Power on the MPS-482HP and monitor the LEDs on its
front panel to verify the connections (see "Fuse, Voltage,
and Load Current LEDs (1–2)" on page 11).
6. Check loudspeaker LEDs to verify whether the
loudspeakers are ready to reproduce audio.
7. Enable output from the audio sources (from the mixer or
processor) connected to the MPS-482HP.
