The Pyle PDWM1904 Single-Channel Wireless System with Headset & Lavalier Microphones features UHF (Ultra-High Frequency) wireless operation, selectable frequencies, and is designed for uses in lectures, performances and similar applications. The system includes a bodypack transmitter, headset and lavalier mics, UHF receiver, a 1/4" cable, and a power supply.

UHF wireless systems work by generating radio waves and forwarding the signal between the microphone transmitter and receiver unit. With a larger range than VHF systems, you'll have an easier time using your system in places with heavy RF activity such as busy cities.

Headset and Lavalier Microphones Included

Headset and lavalier microphones are both included, each with 3.5mm locking connectors for connection to the bodypack transmitter (Please note that only one mic can be used at a time)

Selectable Frequency

PLL-Synthesized control technique - 8 selectable UHF channels

Front-Panel Control

Located on the face of the unit are the adjustable volume control knob, RF and AF indicators, power indicator, antennas, power switch, and channel frequency display

RF Signal Indicator

The RF (Radio Frequency) indicator LED lights when the receiver is successfully obtaining a signal from the transmitter

AF Signal Indicator

The AF (Audio Frequency) indicator LED is lit when the wireless system is successfully receiving an audio signal

Operation Range

Transmitters will work at a distance of up to 164' (50m) from the receiver

Simultaneous Output Use

Unbalanced 1/4" phone plug and balanced XLR output connectors may be used simultaneously to different external devices

Multiple System Use

Multiple UHF systems can be used in the same area without interference. Each system must be set at a different frequency to allow clear transmission

Low Battery Warning

A red light on the transmitter signals less than one hour of battery life remains

What's in the Box

1/4" cable, AC/DC power adapter, bodypack transmitter, headset and lavalier mics, and receiver

Do you need separate speakers for this item?
Asked by: Gee T.
I'm not sure. We did buy speakers to go along with it. We use it with our computer to make the voice on our TV louder. We use Monitor Speakers MS16 by Berhinger. I don't seem them here any longer

are there different frequencies where we could use 2 in rooms adjacent to each other?
Asked by: Joe B.
Sorry Joe, I don't know. We use it in one room only. I purchased this one on the recommendation of our media services folks who knew exactly what I wanted to accomplish with it. We do use it weekly and like it very much.
