IMPORTANT SAFETY INSTRUCTIONS
• To reduce risk of electric shock, never open the unit. There are no user serviceable parts, refer
service to an authorized Rockville service center.
• Do not expose this unit to any kind of moisture.
• Please ensure that the unit is situated in a properly ventilated area.
• Make sure the unit is placed on a level and stable surface.
• Active/Powered DJ/PA Speaker With Built-in Bluetooth
• 2 Wireless Microphones
• Built-in Rechargeable Battery
• Power Cable
• Remote Control
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 speakers
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.
Setting Up Your RAM BT V2 Professional Sound System

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 microphone
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.
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 pattern 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.

Because mixers feature two volume controls (channel and master), when
connecting one via the XLR line in port, the procedure is slightly different. The
RAM-BTv2 Line Level should be set to 50%. Set the mixer master volume to 50%
and make the adjustments in step 3 on the mixer channel level control. If after
making these adjustments the signal still isn’t strong enough, you can additionally
boost the signal by turning up the Line Level control.
When adjusting the Mic Volume control, you must speak into the micophone and
adjust the level control as needed. This is because adjustments to the mic input
are a matter of mic volume in relation to the music volume and not necessarily a
clipping issue.
It is best practice to set your input level controls (gains) in this manner:
1. Unplug all inputs except for the one you wish to set the
gain for. In this instance, the Line In RCA inputs.
2. Set the line level input device volume (smart phone,
tablet, MP3 player, etc.) to 60%.
3. Slowly turn up the level on the selected
input (in this case, the Line Level).
As soon as the clip indicator LED goes on
or you hear any distortion – turn it down
one or two notches.

Troubleshooting
PROBLEM
No sound/
distorted sound
Poor Mic sound
Not enough bass
Mic feedback
Buzzing sound
1. Make sure you are using the Mic In port.
2. If using wireless mics, check the batteries, the volume settings,
and make sure the antennas are fully extended.
Add a subwoofer to your setup – PA speakers do not play deep
frequencies as well as a subwoofer. Regardless of brand or model, if
you want deep thumping bass you must add a subwoofer.
Point the mics away from the speaker. Make sure the mics are
behind the speaker, not in front of it (see page 4).
Make sure you are using a proper cable. For ¼˝ cables, there are
3 types: instrument, TS (unbalanced), and TRS (balanced). Check
the requirements of the connected gear and the input of the
speaker and make sure you are using the appropriate cable.
1. Check that all appropriate cables are plugged in correctly.
2. Check the Volume settings.
3. Be sure your microphone is on.
4. If using a mixing console, make sure fader and balance are set
to center positions and levels are increased.
