1. Choose a microphone with high directivity, i.e. cardioid or hyper-cardioid polar
pattern.
2. Never point the microphone directly down in front of the speaker. Holding the micro
phone in normal position will allow you to be closer to the stage monitor with out feed
back.
3. See illustration below as to position of microphones when mounted in stand.
Cardioid polar patter microphones should always be at a 90 degree angle to the axis of
the stage monitor. Hyper Cardioid polar pattern microphones should be positioned at
an acute angle to the sage monitor.
You may choose to add a feedback eliminating processor to your system for additional
flexibility on stage.
There is really only one volume control on the RAM BT unit, that is the knob marked
MASTER.
The Mic In Balanced volume controls as well as the wireless mic volume controls are
matching devices to match the preamp voltages of the microphones with your RAM BT
unit. Never turn these up to maximum unless indicated by the instructions below. With a
properly matched signal your system will produce less distortion, be subject to less feed-
back, and will produce louder, cleaner and clearer sound. Use the Master control as your
volume once all inputs are matched properly.
