UniAmp Power Amplifier Module , Model 1214
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.
Resetting the UniAmp 1214 may also be carried out
via WinControl; see the WinControl Help files for
more information.

The bi-colour Status LED has several functions:
1. To indicate that the unit’s power supply is
functional, the LED shows green for normal
operation. Note that the presence of mains voltage
is indicated by a neon lamp that is integrated into
the mains switch.
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.
CooLING
The UniAmp 1214 depends on convection cooling. To
ensure trouble free operation of the unit you must:
1. Always ensure that the unit is installed in
compliance with the “Important Safety
Instructions” found in Section 1 of this document.
2. Always ensure that the ventilation openings
are not blocked or covered and are free
from obstruction.
3. Where possible avoid installing the unit in such
a way that the amplifier module is in direct sun
light. Failure to follow this advise might result in
a significant increase of chassis temperature and
may result in the amplifiers thermal protection
being activated.
