System Errors

When a system error occurs, the LINK, CONDUCT, and ERROR indicators ﬂash simulta-

neously in a repeating patttern. You can determine the type of error by counting the num-

ber of ﬂashes. There’s a two second pause between each series of ﬂashes, as shown in the

following illustration.

ACU16-C

NetworkAmp Manager

cannot control and

monitor all power

amps?

Make sure that all power amps are powered up.

Make sure that each power amp is assigned an exclusive amp ID.

Check the RS-485 cable connection between each power amp. If a cable is not

connected properly, or a cable is faulty, power amps further down the line will not

be detected.

Speaker output sounds

out of phase?

Check your Euro-block connector wiring at the ACU16-C and power amps.

NHB32-C

The LOCK indicator

ﬂashes continuously?

This means that the NHB32-C cannot lock to the currently selected wordclock

source. Check and correct the source, or select another.

The PATCH number

ﬂashes continuously?

This indicates that a patch other than the one recalled or stored last is selected.

Recall the patch, or select the patch that was last recalled or stored in order to

stop it ﬂashing.
