Connecting the VLC 302 Charger and Charging the Microphones

LED

NOTE: The charging station is to be used with NiMH rechargeable batteries only.

To connect the charger and charge the microphone(s):

1. Connect the 5 VDC, 2.6 A wall charger (with USB Mini-B adapter) to a

110-130 VAC (US) or a 100-240 VAC (international), 50-60 Hz power source.

2. Connect the USB mini plug end of the adapter to the USB mini jack located on

the back of the VLC 302.

NOTE: The charger can also be powered by a USB source using a mini

USB cable.

3. If required, unscrew and remove the microphone battery cover to install the

battery. Insert the battery, aligning the + and – poles as indicated inside the

compartment.

4. Insert the microphone into one of the charger slots. The microphone LED turns

red to indicate charging, and green when the microphone is fully charged.

NOTE: Microphones can be left to charge for extended periods.

CAUTION: Do not replace the batteries with an incorrect type. Use only

rechargeable batteries specified or provided by Extron, or alkaline batteries.

ATTENTION:

• Do not attempt to charge alkaline batteries.

• Be sure to replace the battery with the correct type and to dispose of

used batteries appropriately.

Installing the VLR 302EB Receiver

The VLR 302EB Receiver outputs audio signals transmitted from the microphones as one balanced mono line level signal.

Connect and set up the VLR 302EB as shown below.

NOTE: For mounting instructions, see the VoiceLift Pro eBUS User Guide.

eBUS connector - Connect an Extron IPCP Pro control processor to this four-pole captive

screw connector.

NOTE: The VLR 302EB requires an eBUS connection with an Extron IPCP Pro

processor for power and communication. If not connected to an IPCP Pro processor,

the VLR 302EB will not output audio.

Extron STP20-2/1000 or STP20-2P/1000 cable is recommended for eBUS connections.

Connect a 4-pole captive screw connector to each end of the cable, wiring both ends as

shown below.

Setting eBUS IDs

Up to eight eBUS devices can be connected to one control processor. Each device connected to the same IPCP Pro control

processor must have a unique BUS ID, which is set using the BUS ID DIP switches (see

, above).

NOTE: If two or more devices have the same eBUS ID, address conicts may cause one or more of the devices to not be

recognized by the IPCPPro control processor.

Various combinations of the six DIP switches (being set to On or Off) provide 64 eBUS IDs (see the VoiceLift Pro eBUS User Guide

for a table showing the DIP switch settings for all 64 possible addresses). Default address is 26.

NOTES:

• Any address can be used except address 0 (binary: 000000), which is reserved as the address of the controller.

• Switch 1 (on the left) is the highest value (32, the most signicant bit).

• Switch 6 (on the right) is the lowest value (1, the least signicant bit).

• Up = On = 1, Down = Off = 0

NOTE: Take into consideration the available power from the IPCP Pro processor. The VLR 302EB requires 4W of power.

DIP switches - Use these DIP switches to assign an eBUS ID to the devices connected to the IP Link control processor.

Each device connected to the control processor must have a unique eBUS ID (see “Setting eBUS IDs” below).

Mono audio output - Connect a balanced or unbalanced audio device (such as an amplier or mixer) to this 3-pole captive

screw connector. Wire the connector as shown below (balanced output is recommended):

5. Turn the microphone(s) on by holding the power button (

) for 3 seconds.

One of the LINK LEDs on the VLR 302EB receiver illuminates to indicate that

connection has been established.

NOTE: Each VoiceLift kit includes VLP 302/VLH 302 microphones

and VLR 302EB receivers that have already been paired. Follow the

steps on the next page to pair the microphone if necessary.

6. Speak in a normal tone of voice, adjusting the volume level (

) as necessary

(to save the volume level, see Saving the Microphone Volume Level on the

next page).

7. When nished, return the microphone to the charging station.

functional. Set the dip switch to the OFF (down) position to enable

“teacher” mode.

• In Student mode, all buttons are disabled except for power. Set

the dip switch to the ON (up) position to enable “student” mode.

3. Apply the appropriate label (provided) to identify the microphone

(see

at right).

4. To wear as a pendant microphone:

a. Open the microphone clip (see

at right).

b. Slide up the lanyard lock under the clip, then release the clip (

Saving the Microphone Volume Level

Saving the microphone level allows the microphone to power on to the stored setting. 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) auxiliary 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 auxiliary 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 auxiliary audio

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

Pairing Microphones with the VLR 302EB Receiver

Each VoiceLift kit includes microphones and a VLR 302EB receiver that have already been paired. If needed, follow the

steps below to pair microphones with a receiver.

Clear previously paired microphones from the VLR receiver

1. Ensure that the microphones are placed in the VLC 302 charger or powered off.

2. Press and hold the Reset button (

) until the Power LED ashes once (approx. 3

seconds), then immediately release and momentarily press the Reset button again (for

<1 second) within 1 second.

Both LINK LEDs (

) blink to conrm pairing has been cleared.

Pair new microphones

Follow these steps to pair each microphone, one at a time, to the VLR 302EB receiver.

NOTE: All paired microphones should be fully charged and turned off before pairing new microphones.

1. Press and hold the LINK button on the VLR 302EB receiver (see

in the image above) for 4 seconds to start pairing mode.

If LINK slots are available, one of the LINK LEDs (see

in the image above) blinks to indicate that pairing mode has started.

NOTES:

• Once initiated, the VLR receiver pairing mode is enabled for 30 seconds, and users must set the microphones to

pairing mode (see step 2) within the allocated time. Repeat the process if the 30 second pairing window time has

been exceeded or if pairing was not successful.

• Receiver Pairing/Discovery mode can also be enabled remotely from a control system that has been congured to

control the VLR receiver. See the VoiceLift Pro eBUS User Guide for details.

2. Follow the steps below for your microphone model:

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

NOTE: The VLP microphone must be in “TEACHER”

mode in order to pair.

While powered off, press and hold the Function (

) and

Power (

) buttons simultaneously for 4 seconds until the

status LED blinks red and green, indicating pairing mode has

started.

• VLH 302: Power the VLH 302 handheld microphone on.

Press and hold the LINK button, located beneath the battery

cover (see

at right), for 4 seconds until the status LED

blinks red and green, indicating pairing mode has started.

NOTE: The receiver assigns the microphone to the rst available LINK slot. The LINK LED on the

VLR receiver will illuminate solid green when the microphone has been paired successfully.

3. Once a microphone has been paired, test the audio by speaking into the microphone, then power the

microphone off. Repeat from step 1 for each microphone being paired.

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

Microphones, on the previous page.
