Your RAM BT V2 unit is set up to produce the full spectrum of sound from its woofer and
tweeter horn combination. The lower frequencies seek out the oor of the room they are
playing and travel along the oor and walls. The tweeter horn is more directional. Hence
when setting up your system its more important to make sure that the tweeter horns are
not blocked by any furniture and are located / aimed at ear level to the listening audience.
Woofer aiming is not as critical as explained previously due to the nature of the woofer
sounds able to travel through various paths even when blocked.
It is therefore recommended that when setting up your system you set up your speak-
ers on speaker stands, such as the Rockville model RVES05 (not included) so that the
tweeter sounds will radiate above the listening crowd. This will guarantee optimum sound
dispersion and achieve clear vocal sound reproduction.
The placement of your microphone is critical in avoiding feedback through your RAM BT
unit. Never set up your microphone in front of the speaker. Always set up your micro-
phone behind the speaker. When approaching the speaker to make any adjustments, we
recommend approaching the speaker from the rear and not walking directly towards the
front of the speaker.
Unlike a PA setup which face the crowd, stage monitors are set up to face the performer
on stage and to direct the sound towards them. This presents a particular problem as
now feed back may occur. To avoid stage monitor feedback the following precautions
should be taken.
Setting Up Your RAM BT V2 Professional Sound System
How To Avoid Irritating Feedback
Stage Monitor Setup

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
exibility 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.

A. Mic input port accepts XLR type connectors and is designed to suit a wide range of
unbalanced signals. We recommend using professional balanced dynamic, condenser or
ribbon mics as they are least likely to be affected by interference. Low cost, high imped-
ance mics can be used, however the level of background noise is higher since an unbal-
anced circuit is far more susceptible to interference.
