1.1       Purpose and Function
VR75 Series Video/Audio Receivers are developed and manufactured by Advanced
Microwave Products (AMP) and distributed by Dyplex Communications (Dyplex).

Receivers are designed for color or monochrome video and audio surveillance.  Receivers
are best operated with AMP’s VT15, VT30, and VT50 Series Transmitters but are
compatible with most other video transmitters on the market.

1.2       Capabilities
AMP Receivers are designed for harsh environments and feature robust packaging and
connectors.  Compact package sizes provide versatility in unit placement and system
applications.

AMP Receivers require no tuning or adjustments.  All units operate directly with any
standard video monitor.  Power requirements are +9 to +16 Vdc and can be derived from
batteries, simple power supplies, or vehicle power.

Whip or “rubber duck” antennas are adequate for many receiver applications.  A variety
of standard and high performance antennas are available through Dyplex.

AMP Transmitters and Receivers are standard equipped with video inversion, selectable
via a slide switch, for a basic level of security.

VR75 Series Receivers are standard equipped for video-only reception.  Up to two audio
subcarriers may be specified for applications requiring audio reception.

VR75 Series Receivers are available with many options allowing customization to
specific applications.  Most common options include frequency selection (full band
selection), dual L/S-band selection, PAL video, and up to two audio subcarriers.

If our standard products and options do not satisfy your requirements, please contact us.
Our experienced design team welcomes your custom specifications.
