Link Switches
Link switches determine how Channel Inputs are routed to
Channel Outputs. When a Channel Input's Link switch is
OFF (set to the down position), the input is only routed to its
corresponding output: for example, Channel Input 1 routed
to Channel Output 1. When a Link switch is ON (set to the
up position), the input is routed to its corresponding output
and the next adjacent output: for example, Channel Input 1
routed to Channel Output 1 and Channel Output 2. If multi-
ple, adjacent Link switches are enabled, the input is routed
to each adjacent output: for example, Channel Input 1
routed to Channel Outputs 1, 2, and 3.
MPS-488HP Link Switches
NOTE:
Channel Inputs are inactive when the
Link switch for the preceding Channel Input is
enabled. Connections should not be made to inactive
Channel Inputs.
Routing Audio Inputs with the Link Switches
The following examples illustrate several common routing
applications for the MPS-488HP.
Routing One Input to Eight Outputs
To route one Channel Input to eight Channel Outputs:
■
Set all Link switches to ON.

Routing Two Inputs to Four Outputs Each
To route two Channel Inputs to four Channel Outputs each:

to ON.

Outputs:

Input Impedance for Linked Channel Inputs
On
When a Link switch is enabled, the Channel Input's unbuf-
fered source signal is transmitted in parallel to each linked
Channel Output. This causes the Channel Input's imped-
ance (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
■
1
1
4 Channel Outputs, 2500 ohms input impedance
■
8 Channel Outputs, 1250 ohms input impedance
