Electro-Voice boasts a rich tradition in the development and manufacture of microphones. With the R300, EV is writing a new chapter in this success story. The R300 is a new wireless microphone system that represents exceptional value for money.

Thanks to features such as One-Touch ClearScan and EZsync, the R300 can be configured for use more swiftly and easily than other wireless systems in its price category; moreover, the production quality and feature set of the R300 – its rack-mountable receiver, its sturdy metal bodypack and handheld transmitters, and its remote-mountable antennae – are on a level and scale normally reserved for expensive professional systems.

This combination of performance quality, professional features and robustness make the R300 the ideal choice for a wide variety of wireless applications, from the capturing of vocals and musical instruments in live performance to use by presenters and MCs to reinforce the spoken word. Separate packages are available for handheld, headworn and lapel microphones.

R300 receiver

With its elegant design and solid construction, the R300 is equally suitable for use as a table-top device or mounted in a 19-inch rack. Thanks to its simple, intuitive operation and easy-to-read display, it represents the ultimate in user friendliness. For professional installations, rack-mounting kits and front-mount antenna cables are available as well as the APD4+ antenna splitter, which provides antenna and power feeds facilitating the simultaneous use of up to four receivers in one rack.

BP-300 body pack

The new, all-metal BP-300 body-pack transmitter is not only robust but compact and easy to use. Capable of running for up to 14 hours on two AA batteries, the BP-300 is even suitable for prolonged venues. The BP-300's Mute function mutes the audio without killing the RF signal, thereby preventing noise entering the system whilst at the same time preserving the audio channel. Two preconfigured bodypack systems are available: one with a lapel- and the other a headworn microphone. The body pack's TA4 connector allows it to be used also in combination with other Electro-Voice lapel- and headworn microphones.

HT-300 handheld transmitter

The HT-300 handheld transmitter comes in a solid metal chassis. As well as being robust, it sits beautifully in the hand. The transmitter's PL22 dynamic microphone capsule makes it the perfect all-round solution for both vocals and the spoken word. The PL22's cardioid pick-up pattern effectively eliminates background noise and reduces the risk of feedback as well as allowing experienced vocalists to make creative use of phenomena such as the proximity effect to enhance their performance.


Tried and tested by top acts and in thousands of installations worldwide, Electro-Voice's ClearScan system scans all 32 of the R300's preset channels before selecting the clearest – all at the push of a button! In an increasingly congested RF environment, ClearScan provides the assurance of interference-free operation as well as maximizing the potential range of the system.


Matching the R300's transmitter and receiver frequencies can also be accomplished at the push of a button. EZsync uses infrared technology to set the transmitter to the correct frequency, confirming operation in one easy step. The failsafe configuration of a wireless system has never been easier.
