The Receiver

The brain of every wireless system, the receiver, is designed to receive the RF signal from the transmit- ter, convert it back into an audio signal, and output it to a PA system or audio device for mixing, record- ing, and amplification.

All Sennheiser wireless EM rack-mountable receivers employ True Diversity technology to ensure stable, uninterrupted wireless reception free from signal dropouts. In a True Diversity setup, a receiver features two independent receiver sections, each with its own antenna (rather than a single receiver module with a single antenna). By means of a comparison circuit, the receiver simultaneously checks both receiver sections many times a second and seamlessly selects the section with the strongest signal. This helps maintain a stable, high-quality signal, significantly reducing the possibility of dropouts. A True Diversity receiver typically costs more to design and manufacture than other “antenna switching” diversity systems, however Sennheiser has always been committed to bringing you the very best.

Another quality which distinguishes evolution wireless G3 receivers is their robust metal construction. In order to protect the sophisticated electronics inside and to provide professional road worthiness, evolu- tion receivers are housed in metal, rather than in the plastic shells used in many other wireless systems. The benefits are obvious: exceptional durability and dependability, even in the roughest conditions.

Fixed receivers

There are three basic types of wireless receivers:

1) The fixed (rack-mount) receiver

The most common version, evolution fixed receivers (EM100G3, EM300G3, and EM500G3) are com- pact, half-rack sized units which can be mounted, along with optional AM2 front-mounted antennas, into a standard 19” equipment rack using the optional GA3 rack adapter.

2) Portable (camera-mount) receivers

Portable receivers are used specifically for film, television, and video applica- tions in which a performer or newscaster is using a wireless transmitter and there is a need to send this back to a video camera or recording device. The EK100G3 is an example of a portable receiver. Portable camera-mount receiv- ers are compact, lightweight, battery powered, and can be mounted directly onto a wide variety of motion-picture or video cameras which have a stan- dard shoe mount for accessories.
