5 Troubleshooting
Symptom Possible Explanation
There is no sound after switching
the amplifier on (sound worked
previously).
The volume may have been set to minimum,
or the amplifier may have been muted (on a
desktop amplifier) before the amplifier was
switched off.
The default volume, bass or treble
settings have changed (when
switching the amplifier on).
If a power failure occurs when the amplifier is
on, the volume, bass and treble settings are
saved and become the new defaults.
Unexpected behaviour occurs
after the digital zone connections
are changed.
The Amplifier’s zone settings are not reset
until all power is removed from the amplifier.
Alternatively use the Reset Amplifier function
on the unit’s C-Bus Status tab in Toolkit.
The wrong amplifier is responding
to source changes.
The “Use Matrix Switcher auto assigned
zone” option may not be enabled. This
option is in the amplifier’s Zoning tab in
Toolkit. After changing the status of this
option (on a live network), use the Reset
Amplifier function on the C-Bus Status tab.
The matrix switcher no longer
responds to button presses.
Turn the matrix switcher off for several
seconds, then on. Use the power switch on
the rear of the matrix switcher, next to the
power cord socket.
The matrix switcher does not
power up.
The fuse may need replacing. Remove the
power cord from the power outlet before
replacing the fuse.
A mains circuit breaker trips when
amplifiers are powered up.
This may occur if more than five amplifier
power supplies are connected to the same
circuit, due to a high inrush current.
