5SIGNAL indicator
Lights up green when the corresponding channel’s out-
put level exceeds 2 Vrms (equivalent to 1/2 W into an 8 Ω load, or 1 W into a 4 Ω load).
6Volume control knobs
Each control knob adjusts the volume of the corresponding channel, in 31 steps from -∞ dB to 0 dB.
*If you wish to lock in the knob settings, you can fasten the supplied security cover over the knobs so that the settings will not be disturbed.
● How to install the security cover
(1)Use the supplied hex wrench to remove the four attachment screws from the amplifier.
(2)Adjust the security cover to the position of screw holes. Fasten it into place using the same screws.
7Air intakes
The amplifier uses forced-air cooling. The cooling fans draw air in from the front and exhaust it through the rear. Please be sure that you do not block the air intakes or exhaust vents.
*The fans do not come on at initial power-on, but will switch on automatically when the temperature of the heat sink rises above 50°C (122°F). The fan speed will then vary automatically as the temperature changes.
