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.
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.
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 the C-Bus Toolkit
software.
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 the C-Bus Toolkit software. After
changing the status of this option (on a
live network), use the Reset Amplifier
function on the C-Bus Status tab.
