3. SETTING UP
3.1. Connecting the amplifier
1.
In your own interest, please observe the Safety Precautions and positioning advice
(Chapter 2)
2. Before connecting your OCTAVE amplifier up, switch off all the other equipment that you intend
to connect to it. This will avoid a source of possible problems when you plug these components
in.
3. Connect the outputs from your preamplifier to the appropriate inputs on the RE 280 MK2 ampli-
fier. Make sure that switch 2 (on the rear panel next to the power amplifier inputs) is in the cor-
rect position.
4. Connect your loudspeakers to your RE 280 MK2 amplifier, making sure that you observe the
correct polarity (positive on the amplifier to positive on the speakers).
5. Check that the amplifier is switched off before connecting the power cable to the
wall
socket.
Before connecting the optional outboard Black Box, ensure that it is switched off.
(see Chapter 8, Black Box)
6. The power switch for the RE 280 MK2 is located on the front panel (see Chapter 4, Operation)
There is no muting or standby facility.
When you switch on, the warm-up LED next to the power switch illuminates. The unit is ready
for use after about two minutes.
7. Check that the volume control is not set at maximum before playing music through the amplifier.
8. Switch the other components on in any order.
3.2. Running in
All OCTAVE equipment is subject to a 48-hour soak test at the factory to burn in the tubes. The
tubes are preselected for use in each particular model.
The sound quality of tube equipment improves throughout the initial running-in period of up
to three months
.
During this time, daily use is beneficial (even at high levels) but not a requirement. Continuous
operation does very little to help reduce the running-in time and is therefore
not recommended.
Power amplifiers should not be left in burn in mode for longer than 4 to 5 hours. The burn in facility
is intended for use only to burn in new output tubes. (See ‘Replacing the tubes’). OCTAVE tubes
fitted to our amplifiers or supplied as replacements do not need to be burned in.
