UniAmp Power Amplifier Module , Model 700
5. RESET
One of the eight Preset memories acts as a “default”
memory, referred to as the “preferential preset” by
WinControl. Users are recommended to store a known
base configuration in this Preset, and to protect it via
WinControl. This Preset may be reloaded by a long (>
1 sec) press on the Reset & Preset Control button (but
see note on previous page regarding early U-16 serial
numbers).
Resetting the UniAmp 700 may also be carried out via
WinControl; see the WinControl Help files for more
information.
6. OTHER
STATUS LED
The bi-colour Status LED has several functions:
1. To indicate that power is being applied to the unit,
the LED shows green for normal operation.
2. To indicate a fault state. The conditions for a fault
state are defined as part of the WinControl settings
file. If the conditions are met, the LED illuminates
red and an error indication is also communicated
via WinControl.
3. To confirm which Preset is being loaded (see
Recalling Presets, Section 4).
4. Unit identification: if the LED is set (in software) to
duplicate the functions of the LED on the front of
the enclosure, it will also confirm unit identity when
requested by WinControl.

CIRCUIT BREAKER
The amplifier module’s mains on/off switch is also a
resettable 6.3 A circuit breaker. If the module draws
current in excess of the rating from the AC mains (as
may happen in a fault condition), the circuit breaker
will trip, disconnecting the power. The fault condition
should be identified and rectified before attempting
to reset the breaker. Note that under extreme fault
conditions, it may not be possible to reset the breaker.
There are no user-replaceable fuses within the Target
System amplifier module.
COOLING
Loudspeaker enclosures equipped with the UniAmp
700 include fan-assisted cooling of the electronic
assembly. The direction of airflow is from intakes
at the front of the enclosure, with exhaust through
slots in the connector panel. The fan is automatic
and is controlled via a “whisper algorithm” via the
DSP section, which adjusts the fan speed according
to temperature and input signal level. Care should be
taken in installation not to restrict the airflow.
