ACU16-C Power Amp Control System

This example shows how up to 32 Yamaha PCxxxxN series power ampliﬁers can be con-

nected to a single ACU16-C for remote control and monitoring via NetworkAmp Manager.

PCxxxxN Series Amp ID Setting

Up to 32 PCxxxxN series power ampliﬁers, each with an exclusive ID from

0 to 31, can be connected to a single ACU16-C. The ID is set using the

power ampliﬁer’s rear panel AMP ID DIP switch, which consists of six indi-

vidual switches, ﬁve for setting the ID, one for turning on and off termina-

tion (marked “T”). The ﬁve switches are individually numbered. IDs are set

using a combination of switches to achieve the required ID. For example, to

set ID #7, you’d set switches 4, 2, and 1 to the ON position (i.e., 4+2+1=7). To set ID #25,

you’d set switches 16, 8, and 1 to the ON position (i.e., 16+8+1=25). To set ID #0, all

switches should be set to OFF. On the last power ampliﬁer in the RS-485 daisy-chain, the

“T” switch should be set to ON to enable termination.
