Installing the VLR 302 Receiver

The VLR 302 Receiver outputs audio signals from the microphones as one balanced mono line

level signal to the PVCA 452 and PVS switcher. Connect the VLR 302 to the PVCA 452 or

PVS 407D PoleVault switcher as shown below. For mounting instructions, see the VoiceLift Pro

User Guide.

A Connect the PVCA 452 or PVS 407D to the VLR 302 output port using the included shielded

Saving the Microphone Volume Level

Saving the microphone level allows the microphone to recall the stored volume level setting when powering on. To save the

microphone volume level:

1. Adjust the volume on each microphone to the desired level.

2. Manually power down each microphone:

• For the pendant microphone, press and hold the power button until the LED turns off.

• For the handheld microphone, slide power switch to off position.

3. Wait 30 seconds before turning the microphones on or placing them in the charger.

Auxiliary Audio Connection

VLP 302

The 3.5 mm mono TS (tip/sleeve) aux audio input on the side of the VLP 302 microphone can be

used to connect an optional lavalier microphone (see the diagram below for connector wiring).

VLH 302

The aux audio input on the VLH 302 microphone can be used to connect audio devices (such as

mobile devices, MP3 players, etc.) to wirelessly transmit audio to the room speakers.

Use a 3.5 mm stereo TRS (tip/ring/sleeve) cable to connect the audio source to the aux audio input

on the side of the VLH 302 microphone (see the diagram below for connector wiring).

Pairing with the VLR 302 Receiver

Each VoiceLift kit includes VLP 302/VLH 302 microphones and VLR 302 receivers that have already been paired. If needed, follow

the steps below to pair microphones with a receiver.

Verify which Microphones are Paired

1. Ensure that the microphones are fully charged. Power each microphone on, one at a

time, to determine if the microphones are paired to the VLR 302 receiver.

NOTES:

• As each microphone is powered on, one of the VLR link slot LEDs (see A

at right) illuminates if the microphone is paired.

• Only one microphone can be paired to each LINK slot on the VLR receiver.

2. Once you have determined which microphones are paired, turn them o.

Pair New Microphones

Follow these steps to pair each microphone to the VLR 302 receiver.

NOTE: All paired microphones must be turned o before pairing new microphones.

1. Press and hold the LINK button on the VLR 302 receiver (see B in the image above) for 4 seconds to start pairing mode.

If LINK slots are available, one of the LINK LEDs blinks to indicate that pairing mode has started.

NOTES:

• Once initiated, pairing mode is enabled for 30 seconds. Users must repeat the process if they have

exceeded the 30 second pairing window or if pairing was not successful.

• Receiver Pairing/Discovery mode can also be enabled remotely using Product Configuration

Software (PCS) or SIS comands (see the VoiceLift Pro Microphone Kits User Guide). Commands

can be sent to the receiver through direct USB connection using a PVCA 452 connection or PVS

switcher connection.

• If adding a new microphone to the system (or replacing a current microphone), and both Link slots

are currently assigned, reset the VLR 302 to clear the pair history (see Clearing Pair History on

the next page).

2. Follow the steps below for your microphone model:

• For the VLP 302: Ensure that the microphone is powered off.

NOTE: The VLP microphone must be in “TEACHER” (o)

mode in order to pair.

Then, press and hold the POWER and FUNCTION buttons (see

A and B at right) simultaneously for 4 seconds until the status

LED blinks red and green, indicating pairing mode has started.

• For the VLH 302: Ensure that the microphone is powered on.

NOTE: The VLH microphone must be in “STUDENT” (on)

mode in order to pair.

Then, press and hold the LINK button, located beneath the battery cover (see C at right), for 4 seconds.

The microphone status LED changes from solid amber to alternating red and green, indicating that pairing

mode has started.

NOTES:

• The receiver assigns the microphone to the first available LINK slot.

• If the microphone is paired successfully, one of the LINK LEDs on the VLR receiver lights solid green.

3. After pairing the microphones, verify that they have been set up properly as shown in the previous section, Setting up the

Microphones on page 2. Repeat steps 1-3 for each microphone being paired.

Clearing Pair History

Follow these steps to reset the VLR 302 pairing history, if needed, using the front panel

Reset button (see A at right). The following reset mode clears pairing history, but

retains settings and usage data.

1. Hold down the Reset button for about three seconds until the Power LED blinks

once.

2. Release and press the Reset button momentarily (for less than one second) within

one second.

Both Link 1 and Link 2 LEDs blink one time, simultaneously, to conrm that the pairing

history has been cleared. Unsolicited response “Pair00” is sent.
