the LED will be continuously red. If the amplifier has over heated and the LED has turned red
refer to section 5.2 Thermal.

Input sensitivity can be adjusted with the ten position rotary switch recessed in the rear panel
by using a flat bladed screwdriver. The control has an 18dB range in 2dB steps and accurately
sets the SPL level for a known input signal level. With the switch set at the 0dB position, 0dBu
of pink noise will produce 96dB SPL at 1 meter.
