Telex/Electro-Voice (Ev) Model HTV VHF Transmitter
General……
The Telex/Ev HTV is a Hand Held Transmitter operating within the VHF
FCC Part 74 frequency range. ( 174.0 to 216.0 MHz )
The transmitter is especially suited for use wherever a small, reliable hand
held wireless microphone is required. Versions are available with optional
microphone capsules.
Please note that each transmitter requires a matching receiver on the same
operating frequency. Standard “off the shelf” frequencies are available. Please see
the Electro-Voice Price List for information.
The Telex Ev HTV Series features single channel crystal controlled units for the
ultimate stability and clarity as well as economy.
SETUP:
Before setting up the transmitter, it is necessary to set up the receiver or at least
check the receiver operation if the receiver has been installed previously.
Place the receiver in an area with the antennas in clear view of the transmitter
operating area. Connect the receiver audio output to the audio input of the mixer,
amplifier or other device. Turn the input to these items down at this point.
Apply power to the receiver. Note that there should be no "Carrier" or TX light on
at the receiver at this time. If there is a light on, this indicates that other users
nearby may be using the frequency or that RF interference is present on the
frequency.
TELEX Ev HTV Owners manual Page 2
If the interference is not severe, suitable operation can sometimes be made
possible by adjusting the squelch control until the light goes off. (Transmitter off)
If the light cannot be made to go off by adjusting the squelch control, then the
frequency should be changed.
Set the receiver audio output control to its midpoint (50 % of rotation).
Open the transmitter battery door and install a fresh 9 volt alkaline battery. Place
the transmitter in the position desired and turn on the power switch. The Green
battery light should flash once and go off. The carrier light at the receiver should
now be on. You are now ready to use the microphone. Place the transmitter mute
switch in the on position (up). Talk in your normal tone and volume. If the Red
light on the transmitter comes on or continues to flash as you speak, turn down the
microphone gain control until the Red light is off or only flash’s on occasion. If
the audio to the mixer or amplifier sounds distorted or clipped, try reducing the
input volume of the mixer or amplifier, or turn the volume down on the receiver.
