PRECAUTIONS

•Power loss may increase as the total speaker impedance gets lower with a number of speaker hookups. Use the largest speaker cable in wire gauge to reduce power loss.

•Switch off the power amplifiers before connecting the speakers or other peripherals.

•Avoid the followings all the time to protect the speakers from damage.

*Turning on and off mixing consoles and other peripherals may cause shock noise when the amplifiers and subwoofer processor are on.

*Shock noise resulting from the connection/ disconnection of inputs/outputs with any powered-up equipment

*Pop noise from microphones without appropriate use of breath-pop screen and/or high-pass filter

*Click noise caused by switching on or off the phantom power for microphones

*Continuous operation at very low frequency from an oscillator, synthesizer or program sources

*High frequency noise developed by fast- forward or fast-rewind operation of a tapedeck

*Out of tune noise in FM broadcast

*Feed-back from microphones or electronics musical instruments.

•Match the polarities of all the speakers by observing the connectors and wire colors when using two or more speakers.

•Read “PROTECTION CIRCUITS” on page 8. Turn down the volume control of the amplifier immediately if the sound suddenly decreases.

•You should use the WS-AT350 Subwoofer all the time with Subwoofer Processor WS-SP2A. The WS- SP2A processes the signal to protect the speakers from damage due to an excessive input signal.
