CHAPTER 3: POWERING MM-10XP SUBWOOFERS WITH THE MPS-488HP

THE MPS-488HP REAR PANEL

The MPS-488HP rear panel includes an AC Input connector,
eight Channel Inputs for receiving source audio, eight Chan-
nel Outputs for delivering DC power and balanced audio,
and seven Link switches for routing audio from inputs to
outputs.

AC Input

The MPS-488HP has a PowerCon twist-lock AC Input con-
nector (line, neutral/line, earth). The connector can accept
different power cord types for outlets used throughout the
world. Make sure to use the correct power cord for the AC
power in your area. The MPS-488HP operates at an AC volt-
age range of 100–240 V at 50–60 Hz.

Channel Inputs

Up to eight channels of balanced audio are received from the
MPS-488HP’s eight Channel Inputs. The inputs are equipped
with XLR female connectors (pin 1, ground; pin 2, signal pos-
itive; pin 3, signal negative). Make sure to use standard bal-
anced XLR cables with all three pins connected on both ends.
Channel Inputs default to being routed to their correspond-
ing Channel Outputs but can also be routed to adjacent out-
puts with the Link switches, though this affects their input
impedance (see “Input Impedance for Linked Channel
Inputs” on page 15).

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.
NOTE: Channel Inputs are inactive when the
Link switch for their 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-488HPp.
Routing One Input to Eight Outputs
To route one Channel Input to eight Channel Outputs:
■Set all Link switches to ON.
