Califone MB-350 owner manual Mic Input Balanced, Mic Impedance Switch, Led, Feedback Information

Mic Input (Balanced)

Use this input for a dynamic (low impedance) microphone with an XLR plug. Condenser/electret (high impedance) microphones which may need phantom (polarizing) voltage.

Mic Impedance Switch

This switch is used to compensate for mic impedance differences. It assures full amplifier output regardless of the microphone used. Note: All connections must be made with shielded cable to avoid hum, buzzing, or radio interference.

LED

There are 3 LED indicator lights behind the speaker grill to give visual assurance of power, RF and audio reception.

Feedback Information

What is Feedback? Feedback is a ringing, howling, or shrill sound that is self-generated by the sound system when using a microphone. It is the result of sound from the speakers being picked up by the microphone(s) in use and then re-amplified by the system. This can form a self-sustaining loop that can damage the sound system if allowed to continue, not to mention annoyance to persons nearby.

How to prevent feedback

ALWAYS STAND BEHIND THE SPEAKER WHEN USING A MICROPHONE. If feedback does occur, immediately reduce the volume. Always plug in the microphone before turning on the power. Reducing the “treble” control may also help.
