Cold air is sucked through the ventilation hole in the front panel and the heat is taken out from the rear
panel. In order to ensure good heat dissipation, please use the equipment in an environment of 0°C~40°C
and ensure that the front and rear panels are unobstructed for clear airflow.
If the temperature exceeds 85 degrees, the output voltage will be reduced so avoid excessive rises in
temperature. If the temperature continues rise up to 90 degrees, the power amplifier will be shut down.
When the temperature drops down to a safe temperature, the equipment will restart automatically.
After prolonged use dust may build up and this can reduce the cooling efficiency. As regular maintenance
always keep vents and fans free from excess dust.
The grounding end of the power cord must be grounded,
otherwise there is a risk of electric shock!
The power cord must have sufficient current capacity, AC power supply voltage and frequency
must be in range of ±10% of the nominal value.
Test signal: Pink Noise, bandwidth limited from 22 Hz to 22 kHz
1/8 power is typical of program material with occasional clipping. Refer to these figures for
most applications.
1/3 power represents program material with extremely heavy clipping.
