Music is distorting
• MAC24WP Music Input
Wallplate level is too high
• One or more Volume
Controls may be miswired or defective
1. Make sure you are feeding only a line level
audio output (not speaker level!) to the
Music Input Wallplate. Turn down the input
level adjustment on Music Input Wallplate.
2. If music still distorts, one or more volume
controls may be mis-wired or defective. To
verify, remove all volume controls from the
MAC24. Using an ohm meter on the disconnected wires coming back from the volume control to the MAC24, check to see
that the impedance between the L+ and L-,
and R+ and R- of all pairs of wires equals 6
to 9 ohms.
If, after trying all of the above, the problem
persists, call ELAN Technical Support FROM
THE JOB SITE for assistance.

4. Remove all volume controls from the
MAC24. Using an ohm meter on the disconnected wires coming back from the volume control to the MAC24, check to see
that the impedance between L+ and L-,
and R+ and R- of all pairs of wires equals 6
to 9 ohms.
