VoiceLift Pro Microphone Features
• Lightweight microphones — The microphones are made of lightweight and
impact-resistant polycarbonate material. The VLP 302 pendant microphone can be
worn comfortably around the neck or clipped to clothing. The VLH 302 can be used for
multiple presenters and as a student pass-around microphone.
• Built-in DSP — The receiver has an integrated digital signal processor (DSP) that
maximizes sound quality and intelligibility.
• Two microphones per classroom — An installed VoiceLift System supports up to
two microphones in each classroom and can be used by instructors and students.
• Power switch — The VLP 302 pendant microphone has an easily accessible switch
on the side to mute the sound and power the microphone on and off. The VLH has a
sliding switch which toggles the microphone on and off.
• Volume buttons — Volume buttons on the VLP 302 are conveniently located, enabling
the presenter to easily raise and lower the volume during use. Volume buttons on the
VLH 302 are hidden within the battery compartment.
• Instant alert e-mail messaging — The VoiceLift receiver can be configured to allow
the teacher to send e-mail alerts, if needed, by pressing the VLP microphone Volume
buttons (see DRelays 1 and 2 on page 12 and Setting up VLP 302 Instant
Alerts on page 16 for details).
• Auxiliary microphone input (VLP 302) allows use of an optional lavalier or headset
microphone.
• Auxiliary audio input (VLH 302) for an external audio source, such as an MP3 player.

outputs a balanced mono line level signal (-10 dBV) to the PoleVault switcher.
CPoleVault switcher — The PVS 407D PoleVault switcher functions as an amplifier
for the VoiceLift System. It amplifies the audio signal from the VLR 302 receiver and
sends it to the speakers. The switcher powers speakers placed throughout the room to
improve the signal-to-noise ratio of the voice to at least +15 dB.

LED indicators when the microphone is charging:
LED Color Indication
Red – steady Battery charging
Green – steady Battery fully charged
Red and green – alternate blinking Incompatible, faulty or failed battery detected. Replace battery.
BMicrophone acoustic audio input ports — The microphone receives voice audio through
these two acoustical ports. Do not block these ports while the microphone is in use.

VoiceLift Pro Microphones User Guide • VLM Kit Installation and Operation 8
CAuxiliary microphone input (Audio In) — Connect an auxiliary lavalier microphone
into this 3.5 mm mono auxiliary mic input jack. When an external lavalier microphone is
connected, the built in microphone elements in the VLP 302 are disabled.
DFunction button — When this button is pressed and held for two seconds, the
microphone signals the receiver to toggle Relay 2 to its opposite state.
NOTE: The status LED flashes amber for 5 seconds, indicating that the relay has
been toggled.
Also, when this button is pressed simultaneously with the Power button, it initiates Link
(pairing) mode.
ESpring clip — Use this clip to attach the VLP 302 to clothing or to a lanyard (included)
(see step 4 on page 13 for instructions).
The lanyard lock is used to retain proper position of the microphone when clipped to
the lanyard. The breakaway clasps help to release the lanyard from around the neck if
it is pulled tightly. Place this clasp at the back of your neck when wearing the pendant
microphone.
FMicrophone identification label recess — Place the appropriate provided sticker in
this space to identify the microphone user (see step 3 on page 13).
GPower and mute button (Off/Mute/On) — Press and hold the Power button (for
three seconds) to power the microphone on or off.
With the device on, press and release this button momentarily to mute or unmute the
microphone.
HI Volume buttons — Raise or lower the microphone volume.
Pressing and holding both of these buttons simultaneously for 3 seconds sends a signal
to the receiver to close its Relay 1 port. This is typically used to trigger an alert (see
Setting up VLP 302 Instant Alerts on page 16).
JCharging contacts — These make contact with the contacts in the charging station
when placed into the VLC 302. A full charge can take up to 5 hours.

Installing the VLC 302 Charger and Charging the Microphones
The VLC 302 charges the microphone battery. It is powered by an external wall power
supply (provided). The microphone battery requires up to 5 hours to charge fully. It is safe
to charge for extended periods, but Extron recommends storing the microphone out of the
charger with the battery removed.
NOTES:
• The charging station is to be used with NiMH rechargeable batteries only.
• Fully charge the supplied batteries before first use.
Follow these steps to connect the charger and
charge the microphones.
1. Connect the 5 VDC, 2.6 A wall charger
from a 110-130 VAC (U.S.) or a
100-240 VAC (international), 50-60 Hz
power source, to the mini B USB adapter.
2. Connect the USB mini plug end of the
adapter to the USB mini jack located on the
back of the VLC 302 (see 2at right).
3. To install the battery, remove the microphone battery
cover as follows:
• VLP 302: Unscrew the two rear panel screws
located on either side of the rear clip.
• VLH 302: Slide the battery cover downward
until it stops, then lift the cover up and off the
microphone.
Insert the battery, aligning the + and – poles as
indicated inside the compartment.
CAUTION: Use only NiMH rechargeable batteries provided by Extron when charging
the microphone. Use of any rechargeable battery other than the type provided by
Extron may cause explosion, chemical leakage, and injury.
ATTENTION : Utilisez uniquement les piles rechargeables de type NiMH fournies par
Extron, lorsque vous rechargez le microphone. L’utilisation d’une pile rechargeable
différente du type fourni par Extron peut présenter un risque d’explosion, de fuite de
substances chimiques, ou de blessure.
ATTENTION: Be sure to replace the battery with the correct type and to dispose of
used batteries appropriately.
ATTENTION: Assurez vous de remplacer les piles par le bon modèle et de jeter les
piles usagées de façon appropriée.

Installing the VLR 302 Receiver
The VLR 302 receiver outputs audio signals from the microphones as one balanced mono
line level signal to the 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.
Connect the VLR 302 to the PVS 407D PoleVault switcher as shown below. For mounting
options and instructions, see Step 1 — Mount the VLR 302 Receiver on page 19.

USB cable for device configuration and firwmare updates only.
CRJ-45 output connector — Connect the PVS 407D to this RJ-45 connector, using a
shielded RJ-45 cable as shown below.
NOTE: The receiver is powered by the PVS switcher. This connection also allows
for communication between the switcher and the receiver, to send configuration
commands and receive relay status information.

DRelays 1 and 2 (normally open/unlatched) — Wire this 4-pole captive screw connector
for relays 1 and 2 (see Setting up VLP 302 Instant Alerts on page 16).
• Relay 1 is triggered to close (latched) for 5 seconds when both volume buttons on
the microphone are pressed simultaneously for 3 seconds. The relay reverts back to
normally open once the 5 seconds has expired. Microphones must be configured
as "teacher" microphones to trigger relays.
• Relay 2 is triggered to close when the Function button on the microphone
(configured as "teacher") is pressed for 2 seconds. The relay stays closed (latched)
until the Function button is pressed and held again for 2 seconds.
