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 inputs from your amplifier to the appropriate outputs on the HP 500 SE amplifier.
4. Connect your loudspeakers to your power 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.
6. The stand by/power rotary switch for the HP 500 SE is located on the front panel (see Chapter
4, Operation)
7. Check that the volume control is not set at maximum before playing music through the
amplifier.
8.
Switch on the mains power, the push-button-switch is located on the rear panel
of the power supply.
The preamplifier needs approx. 4 minutes warm up time. In the warm up
time the output is shorted to ground to avoid disturbances.
When switching the mode switch from normal to - 6 dB gain operation, the
output is muted for approx 2 minutes.
If you switch from high to low or vice versa the muting time will start
again
9. Switch on the other components.
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.
