2 All models feature an XLRbalanced input, with adjustable input sensitivityfrom -12dB to 0dB. A parallel male XLRconnector enables convenient amplifier linkingin multiple amplifier installations. Automaticthermal protection circuitry is provided and an idling circuit protects against thermalrunaway. A two-speed fan helps ensurereliability, switching to high-speed when theamplifier is under heavy load. A switchable high-pass filter helps provide driver protection fromexcessive low frequencies. Front panel LEDsindicate output levels of -40dB, -10dB andclipping, as well as protection circuit ground-lift switch is provided to isolate signalground from chassis ground.

3 The outputs are4 , 70V, or 100V (output transformer variesdepending on country). The units can bepowered by 100-120 VAC/220-240 VAC(depending on country requirements), or24 VDC, enabling the unit to be used as part ofa portable PA system, or connection to astandby Power supply for emergencyoperation.
