Setting Up Your RAM BT V2 Professional Sound System

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 floor of the room they are playing and travel along the floor 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.

How To Avoid Irritating Feedback

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.

Stage Monitor Setup

Unlike a PA setup that 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 feedback may occur. To avoid stage monitor feedback the following precautions should be taken.

  1. Choose a microphone with high directivity, i.e. cardioid or hyper-cardioid polar
  2. Never point the microphone directly down in front of the speaker. Holding the microphone in a normal position will allow you to be closer to the stage monitor without feedback.
  3. See the illustration below as to the position of microphones when mounted in a 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.

Setting Level Controls

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 (smartphone, 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.

PLEASE NOTE

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.

Wireless Speaker Linking

The RAM-BT v2 features True Wireless Stereo (TWS) Bluetooth linking. This means you can purchase 2 of these speakers and link them together to play in stereo wirelessly.

  1. Make sure both RAM-BTv2 unit’s power switches are in the ON position and that they are within 32 feet of each other.
  2. Press the Mode button on both of the units to enter Bluetooth mode. The LCD screens should show that the speakers are not connected via Bluetooth or to another speaker.
  3. Press the SCAN/TWS button on one of the units for 3 seconds (3a). If pairing is suc­cessful the unit’s LCD screen will read “BLUETOOTH BT-A Connected” (3b). This is the primary and all functions will be controlled by this unit.
  4. The secondary unit’s LCD screen will read “BLUETOOTH BT-B Connected”.
  5. Once the speakers are connected, go to your phone’s Bluetooth interface and select ‘ROCKVILLE” from the list of devices. If the connection is successful, you will hear the same audio from both units. You are now ready to enjoy the true wireless stereo sound!

PLEASE NOTEOnce the units are in TWS mode, the primary (left) unit becomes the master unit and will control all functions.

APPLICATION USES

Microphone Presentations

Your RAM-BT v2 features ultra-low noise Mic input via an XLR port and VI TRS stereo jack.

  1. Make sure the Power switch is in the OFF position.
  2. Plug your microphone into the XLR/1/4″ combo jack.
  3. Switch on the RAM-BT v2 unit.
  4. Refer to the ‘Setting Level Controls’ section of this manual for instructions on how to properly adjust the Mic Volume controls.

Always stand behind the Power Gig when making your microphone adjustments to avoid feedback distortion.

Talk over Feature

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.

Line Input

You can use the Line In XLR input to connect a mixer or the RCA inputs to connect an additional stereo signal source such as a smartphone, tablet, MP3 player, CD player, etc.

  1. Make sure the Power switch is in the OFF position.
  2. Connect the mixer to the XLR input or line-level signal source to the RCA inputs (never use both at once).
  3. Switch on the RAM-13T v2 unit.
  4. Refer to the ‘Setting Level Controls’ section of this manual for instructions on how to properly adjust the Line In level control (gains).

Wireless Microphone Set-Up

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 the ON position.
  2. Keep both Mic A Volume and Mic B Volume and Channel B wireless Mic Volume at Min position.
  3. Press the VHF power on button (red indicator LED should be on).
  4. Switch on one microphone. It should automatically connect to the corresponding channel and the LED for that channel should light up.
  5. Repeat steps 1 through 5 for the second microphone.
  6. Use the Mic A / Mic B volume controls to adjust each microphone’s volume.

Record Function

You can record the input from any mic or line input source to a USB or SD card.

  1. Make sure there is a USB or SD card inserted and that your input source is ready.
