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.

Your RAM BT features two ultra-low noise Mic/Line inputs via XLR & 1/4˝
TRS stereo jacks.
1. Make sure the RAM BT unit power switch is in OFF position.
2. Plug in your microphone.
3. Keep Master Volume at Min position.
4. Turn Input 1 Level to Min position.
5. Switch on the RAM BT unit.
6. Slowly turn Input 1 Level clockwise until you achieve appropriate volume setting
Proper function is achieved when you hear audible distortion. The above adjustment
matched the microphone preamp to the input volume of the RAM BT unit.
7. Now turn up the Master Volume to necessary volume by rotating clockwise.
Always stand behind the RAM BT unit when making your microphone adjustments to
avoid feedback distortion.
Set up microphone #1 as instructed above. Using same set up instructions, insert mi-
crophone #2 into ultra-low noise 1/4˝ TRS input which features its own separate Volume
control. Use this Volume control to increase the microphone level and balance the inputs
between the two microphones before attempting to adjust the Master Volume.

Your RAM BT unit comes with two wireless microphones. To connect the microphones to
the unit follow these steps:
1. Make sure the RAM BT unit power switch is in ON position.
2. Keep Master Volume at Min position.
3. Keep both Mic A Volume and Mic B Volume and Channel B wireless Mic Volume
at Min position.
4. Press the VHF power on button (red indicator LED should be on).
5. Switch on one microphone. It should automatically connect to the corresponding
channel and the LED for that channel should light up.
6. Repeat steps 1 through 5 for the second microphone.
7. Use the Mic A / Mic B volume controls to adjust each microphone’s volume.
8. Now turn up the Master Volume to necessary volume by rotating clockwise.

When setting up for larger venues, a mixing console becomes a critical piece of equip-
ment for appropriately mixing signals from multiple inputs such as singers, speakers,
effects devices, musicians and of course allows for multiple speaker utilization.
To connect a mixing console begin by.
1. Make sure the RAM BT unit’s power switches are in the OFF position.
2. Turn Master Volume to 0 position (both units).
3. Turn Input 1 Level to 0 position (both units).
4. Connect the LEFT OUTPUT of mixer to the Mic In connection of your Left
RAM BT unit.
5. Connect the RIGHT OUTPUT of mixer to the Mic In connection of your Right
RAM BT unit.
6. Switch ON your RAM BT units.
7. Slowly raise the level of the mixer output to the 0dB level position.
8. Slowly turn Input 1 Level clockwise until you achieve appropriate volume setting
Proper function is achieved when you hear audible distortion. The above adjustment
matched the mixer preamp to the input volume of the RAM BT units.
9. Turn Master Volume up to achieve proper volume (both units).

You can use the Line Input function when you wish to hook up an additional stereo signal
source: Mixers, Keyboards, CD players, DVD music players, MP3 players etc. can be
plugged directly in to the RCA jacks labeled LINE INPUT.
To connect a mixer, keyboard, CD, DVD music player or MP3 player.
1. Make sure the RAM BT unit power switch is in OFF position.
2. Turn Master Volume to 0 position.
3. Turn Line/MP3 Level control to 0 position.
4. Connect the music source unit to the RCA jacks marked Line Input.
5. Use the push button (located next to RCA jacks) to select between Line input
or MP3 input.
6. Switch ON your Power Gig unit.
7. Slowly turn the Line/MP3 Level control clockwise until you hear audible distortion,
then turn it down slightly. This indicates the maximum input voltage gain is
matched and set properly.
8. Turn Master Volume up to achieve proper volume.

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.
B. Line input port accepts unbalanced 1/4˝ TRS plugs.

In the ON position the TALK OVER function gives the microphone priority over all other
features so that the microphone’s volume level will be higher. When the TALK OVER
function is in the OFF position, the microphone can be used in conjunction with any other
feature (Bluetooth, MP3, SD, etc.) at the same sound level.
