Troubleshooting
This section contains troubleshooting hints which should
help you locate a problem. Systematically check the inputs
and outputs. Since this is a two zone system, double check
the problem by confirming it on the other zone. Please refer
to Section One for an illustration of the front and rear
panels.
Summary.
Check AC Power switch. Reset switch off/on. If unit operates
only momentarily, service is required (DC fault).
No Sound.
Switch on but meters not illuminated. Check AC cord/AC
service. A lamp plugged into the accessory outlet should
light when the Power Switch is “On”. If AC service is good
and switch is “On”, problem is with MPS 2300. Refer to
Authorized Service personnel.
Switch on and meters illuminated. Check Master Volume
control, make sure it is at the proper setting. Check meters
while selecting a source which has an input indicator
flashing.
Meters illuminated but input indicators not flashinq.
Problem may be with source equipment or connections
(See below).
If meters are active. Check speaker connections and
speakers.
If no meter action. Check Pre Out/Amp In jumpers or
external signal processor if connected.. If jumpers
disconnected, reconnect. If jumpers are in place check
music and page volume controls and refer to following
sections. If signal processing equipment is in line
(equalizer, etc.), disconnect and replace jumpers. If sound
comes back problem is with signal processing equipment
or connections. Refer as necessary to Set-Up sections. If
still no sound (page and music) refer to service personnel.
Check remote control if connected. Check input gains and
sensitivity settings.
Very Faint Sound.
