Link Switch Routing Examples

The following examples illustrate the routing applications for 
the Link switch.

Routing One Input to Two Outputs

To route one input to both channel outputs:

Set Link switch to ON.

Routing Each Input to its Corresponding Output

To route each input to its corresponding channel output:

Set Link switch to OFF.

Input Impedance for Linked Channel Inputs

When the Link switch is enabled, channel 1 input’s 
unbuffered source signal is transmitted in parallel to both 
channel 1 and 2 outputs. This selection causes the channel 
input’s impedance (normally 10 kOhms for one loudspeaker) 
to be reduced for each linked output. For example:

1 channel output, 10 kOhm input impedance

2 channel outputs, 5 kOhm input impedance

To avoid distortion when linking channel inputs, make 
sure the source device can drive the total load 

impedance of the linked loudspeakers. Most source devices 
are capable of driving loads no smaller than 10 times their 
output impedance. To drive two loudspeakers linked from a 
single channel input, the source device should have an 
output impedance of less than 500 ohms.

Channel Outputs

The MPS-482HP’s two channel outputs deliver DC power 
(48 V DC) and balanced audio to two loudspeakers. The 
channel outputs are available as Phoenix 5-pin male 
connectors.

NOTE: 

For information about cable 

requirements for your loudspeaker, refer to its 

operating instructions. For information on cables and 
cable accessories available from Meyer Sound, see 
Appendix A, “MPS-482HP Cable Accessories.”

TIP: 

A single composite cable (such as Belden 

1502 or equivalent) wired for both DC power 

and balanced audio can be used to connect 
loudspeakers to channel outputs.

CAUTION: 

Make sure loudspeaker cables are 

wired correctly. For details about assembling 

loudspeaker cables, refer to Appendix B, “Assembling 
Loudspeaker Cables.”

NOTE: 

HMS-15 loudspeakers require power 

from two contiguous channels of the MPS-

482HP. If audio signal is present on both channels 
connected to an HMS-15, the signal is summed 
internally.
