7、ence Amplifier. Like other Phonic MAR series power amplifiers MAR 2/4/6, this unit is designed to provide a good combination of power, audio clarity, reliability and durability. Especially, optimized for studio monitoring applications and moderate-power live performance setups, the amps main feature

8、s include: ? 150 watts per channel into 4 ohms, 100 watts per channel into 8 ohms ? Front panel LED Indicators for Protect, Clip otherwise the speakers components could be damaged. 8. Ground Lift Switch This switch allows the circuit and chassis grounds to be separated in case on a ground conflict.

9、In normal use the switch should be in the Ground On position. Lifting the ground (Floating position) may resolve the ground conflict, but which means that circuit grounding depends on other connected components. Deficiencies in other components grounding will affect the sound and a serious electric

10、fault with the amplifier could damage other components in the system. For the best combination of safety and performance,it is highly recommended to keep the switch in the “Ground On” position, 9. Binding Post Output Ch1/ Ch2 These are suitable for banana plugs, spade lugs or bare wires. Spade lugs

11、and bare wires should both be screwed done tightly to exclude oxygen, and care should be taken to avoid loose strands of wire that may cause short circuits.
