THERMAL CUT-OUT & 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
Elicit-
R
was to keep the capacitors in the
signal path to a minimum to prevent unnecessary sound degradation at this crucial
line level stage. In order to achieve this requirement the output of both the pre and
power amplifier 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.
