Belden 1502 Cable
The Belden 1502 multiconductor cable is an effective, con-
venient way to connect an Ashby loudspeaker system. DC
power and balanced audio use dedicated conductors in a
single cable jacket. Table 4 shows the wiring conventions.
The thicker red and black wires (18 AWG) are for DC
•
power.
The blue, white, and shield drain wires for audio.

Using Separate Cables for DC Power and
Audio
If your installation does not allow using Belden 1502 multi-
conductor cable, or requires cable runs longer than 150 ft,
use separate cables for DC power and balanced audio (see
"Cable Length and Gauge" on page 12). Use a high-quality,
balanced cable for audio. Attach the separate cables to the
Phoenix connector as shown in Figure 4.
Note the orientation of the connector while assembling the
cable. This view shows the screws facing you.
CAUTION: It is very important to verify and
measure the cabling before applying power.

ON/STATUS LED

The LED on the Ashby connector panel is primarily intended
for use at the factory and before installation since it cannot be
seen when a loudspeaker is installed.
CAUTION: Avoid "hot plugging" by inserting
the Phoenix connector into the Ashby loud-
speaker with live 48 V present (MPS Power Supply
powered ON).
The MPS Power Supply can supply basic information about
Voltage and Load Current on its front panel LEDs. The Volt-
age and Load Current LEDs verify whether each channel out-
put has voltage and whether the connected loudspeakers are
receiving DC power and audio.
For more information, refer to the specific MPS Power Supply
Operating Instructions for your power supply model.
If you require more information about the status of the loud-
speakers connected to the MPS Power Supply, we recom-
mend using RMS (Remote Monitoring System), available on
some MPS Power Supply models.
The On/Status LED on the Ashby connector panel indicates
the loudspeaker's operational status with three colors:
Normal: Green
•
Limiting: Yellow
•
Clipping: Red
•
Normal
When powering on the Ashby loudspeaker, the On/Status
LED indicates the following startup events:
1. Multiple colors flash during its power-on sequence.
2. When it turns solid green, the power-on sequence has
completed and the loudspeaker is ready.
