• Make sure that the microphones are fully seated in the charging station to ensure proper charging.

ATTENTION:

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 controller amplifier, PVS switcher or connected audio amplifier. In dual microphone systems, the signals from the two microphones are mixed at the receiver and then output to the connected audio amplifier.

Feedback Suppression

This feature activates signal processing to automatically suppress audio feedback. Feedback suppression can be enabled using SIS commands or through the PCS software application. When using PCS, the feature may be enabled from within the PVCA 452 or PVS 407D configuration screen or via direct USB connection to the VLR 302.

The feedback suppressor automatically inserts notch filters at the frequencies where feedback is detected. Filters are held for 60 minutes (default). However, filter hold time can be adjusted through SIS commands (see SIS Configuration and Control on page 25 for command and adjustment range).

Connections

Connect the VLR 302 to the PVCA 452 controller amplifier or PVS 407D PoleVault switcher as shown on the next page. For mounting options and instructions, see Step 1 — Mount the VLR 302 Receiver on page 18.

Pairing the Microphones with the VLR 302

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 LEDs (see Ⓐ at right) illuminates if the microphone is paired.

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

• Once you have determined which microphones are paired, turn them off.

Pair New Microphones

Follow the steps in this section to pair microphones to the VLR 302 receiver.

NOTES:

• All paired microphones must be turned off before pairing new microphones.
• 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 paired history (see Resetting the VLR 302 on page 30 for reset options).

• Clearing the paired history removes microphone Link information from the VLR 302. All microphones must be paired again, including any microphone that was previously paired.

• Press and hold the Link button on the VLR 302 receiver (see B above) for 4 seconds to start pairing mode. If a Link slot is 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 via SIS comands.
  Commands can be sent to the receiver through direct USB connection or through PVCA 452 and PVS switcher connection.

• If both Link 1 and Link 2 LEDs blink when initiating pairing mode on the VLR 302, this means that both Link slots are currently occupied and paired to microphones.

• 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" mode (DIP switch in the down position) in order to pair (see ② on page 13).

Then, press and hold the Power and Function buttons (see A and B at right) simultaneously for 4 seconds until the microphone status LED blinks red and green, indicating pairing mode has started.

• For the VLH 302:

Ensure that the microphone is powered on.

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

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

NOTE: 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.

1. After pairing the microphones, verify that they have been set up properly as shown in Setting up the Microphones on page 13.

Setting up VLP 302 Instant Alerts

Instant alerts can be triggered using VLP 302 pendant microphones set to teacher mode. Press and hold both volume buttons simultaneously for 3 seconds to send a command to close the normally open relay (relay 1) on the receiver for a duration of 5 seconds. When relay 1 is closed, the status LED on the VLP microphone lights red to indicate the triggered state.

When connected to the PVCA 452, the relay state can be monitored and set up to trigger an action via Global Configurator software. This relay can also be integrated with various life alert systems or connected to a control processor, such as an Extron MediaLink MLC controller, to trigger an action (for example, sending an e-mail). After the 5 second pulse, the relay toggles back to the open state.

NOTE: The MLC can be configured using Global Configurator software (see the Global Configurator help file for configuration details).

Tips for Using the Microphones

• Speak in a normal tone of voice. When the microphone is set up properly, voice audio is amplified just above ambient room noise.
• Mute or turn the microphone off while having private conversations.
• Return the microphones to the charging station when not in use. Verify that the microphones are fully seated in the VLC 302 charger to ensure batteries are charged.
• If you are experiencing intermittent audio problems, check the batteries and replace them if necessary. NiMH and alkaline batteries are supported.

f. On the microphone, lower the volume to an appropriate level:

• The level of your speaking voice should be enhanced, but not loud enough to sound like a paging system.
• Check the LEDs on the PVS switcher. The green Normal LED should light when you speak, with the red Peak LED blinking occasionally. Level indicators for the PVCA 452 can be found in PCS software.

Level set too high. Lower input gain.

Level has been properly adjusted.

Signal threshold -20 dBV (-18 dBu)

NOTE: The microphone audio should be slightly audible to the person speaking into it. Have another person listen for the audio levels and check for sound quality.

1. Test any optional devices that have been installed.

SIS Configuration and Control

This section provides information on how to configure the VoiceLift system using Extron Simple Instruction Set (SIS) commands. It provides a list and descriptions of the available commands. Topics include:

• Overview
• Host to Receiver Communication
• Commands and Responses
  • Command and Response Table for SIS Commands

NOTE: The VoiceLift System can also be configured using the Extron Product Configuration Software (PCS). For full details about using PCS, see the PlenumVault Digital Systems Installation Guide or the PVS 407D PoleVault Digital Switcher User Guide available online at www.extron.com; or see the PCS help file, embedded in the PCS software.

Overview

The VLR 302 receiver can be controlled via a host computer that is connected to the USB control port on the VLR 302 receiver. Commands can be sent from the computer using a communication software program such as Extron DataViewer. SIS commands are available for various functions, such as obtaining information and status for the VLR 302 ports, controlling relay functions, pairing, and resetting the VLR 302.

Host to Receiver Communications

SIS commands consist of one or more characters per field. No special characters are required to begin or end a command sequence. When the VLR 302 recognizes a valid command, it executes the command and sends a response to the host device. All responses from the receiver to the host end the character string with a carriage return and a line feed (CR/LF = ←). A string is one or more characters.

Error Response

When the VLR 302 receives a valid SIS command, it executes the command and sends a response to the host device. If the receiver is unable to execute the command because the command is invalid or contains invalid parameters, it returns the following error response to the host:

E13 - Invalid value (the number is out of range)

Timeout

A pause of 10 seconds or longer between command characters results in a timeout. The command operation is aborted with no other indication.

Commands and Responses

Using the Command and Response Table

The Command and Response Table for SIS Commands on page 27 lists the following:

• Valid ASCII command codes
  • The receiver responses to the host
• A description of the command function, or the results of executing the command

The ASCII to hexadecimal conversion table below is for use with the command and response table:

Resetting the VLR 302

Follow the steps below to reset the VLR 302 receiver using the front panel Reset button (see A on page 11). The VLR 302 may also be reset using the Product Configuration Software (see the help file for the VLR 302 module within PCS).

NOTE: All paired microphones must be turned off in order to properly reset the VLR 302 receiver.

Reset Mode 1

This mode resets the unit to its base factory firmware.

Hold down the Reset button while the switcher is being powered up. The receiver boots to its base factory firmware. Any firmware that has been loaded over the base firmware is ignored.

Reset Mode 2

This mode resets 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.
3. Both Link 1 and Link 2 LEDs blink one time, simultaneously, to confirm that the pairing history has been cleared. Unsolicited response "Pair00" is sent.

Reset Mode 3

This mode is an absolute factory reset. It will reset the unit to factory default settings, and also clear pairing and usage data.

1. Hold down the Reset button for about six seconds until the Power LED blinks two times.
2. Release and press the Reset button momentarily (for less than one second) within one second.

Front panel LEDs cycle, and all settings (including pairing history) are cleared from the unit. This reset is the same as sending the 'ZXXX' SIS command.
