Thermal cut-out and DC protection
If the amplifier reaches a temperature liable to cause internal
electronic damage, a thermal protection sensor will shut the unit
off. If this occurs, there will be no sound emitted from the speakers.
The unit should be turned off for at least 10 minutes to allow for
cooling. After this period, the amplifier should automatically reset and
continue to work normally. If it does not, turn the unit off for a longer
period, allowing complete cooling of the amplifier before retrying.
The thermal cutout should only occur with continuous high level
driving of a difficult load. If it occurs under normal conditions, there
could be a problem with insufficient airflow around the heat sinks or a
fault with the loudspeakers. In this case it is advisable to contact your
Rega dealer.
One of the design requirements of the AETHOS was to keep the
capacitors in the signal path to a minimum to prevent unnecessary
sound degradation. In order to achieve this requirement, the outputs
of both the pre-amplifier and power amplifier (speaker) are DC
coupled. A servo control is applied to the pre-amplifier. In the unlikely
event of a circuit failure causing any one of the above outputs to
produce an excessive DC voltage, the DC protection will activate
within milliseconds, protecting any connected device.
Operating temperature and short circuit protection
The recommended ambient operating temperature is 5 °C to 35 °C.
Allow adequate air circulation around the heat sinks on the left and
right hand sides, as these are the heat sinks for the power amplifier
and will run hot with high listening levels. This unit is intended for use
in moderate climates.
If in the event that the speaker leads are shorted, the fold back
short circuit protection will protect the output stage from excessive
currents. This protection circuit is not placed in the audio signal path
and therefore does not affect sound quality.
Warning:
To reduce the risk of fire, electric shock or product damage,
do not expose the unit to rain, moisture, dripping or splashing and
ensure that no objects filled with liquids, such as vases, shall be
placed upon it. Do not remove the case covers. There are no user
serviceable parts inside.
No naked flame sources, such as lighted candles, should be placed on
the apparatus.
Remote control
The Solaris system remote (supplied) is a system remote handset. It
allows you to operate all the various remote controllable functions
of this and many other Rega products (batteries included - 2 x AAA
Alkaline).
