Powering Up
Ios
is activated by depressing the On/Off button situated to the
left of the control panel. The power indicator LED will glow
steadily.
Always activate
Ios
before the power amplifiers and de-
activate after they have been switched off.
After switching off, the indicator will extinguish.
Due to the nature of the circuit topology, there is a short period
immediately after switching on when the quiescent current has
not stabilised. This condition results in reduced output from the
pre-amp.
This Rega amplifier circuit has been carefully designed to work
with a minimal “ warm up” period. Some manufacturers and
retailers may recommend leaving amplifiers permanently
switched on, Rega cannot condone such practise in these
environmentally sensitive times.
We would recommend that your Rega amplifier is always
switched off after use. Full sound quality is attained after less
than ten minutes (a process speeded up by playing music!)
