At the NAMM show in Anaheim/USA (January 13 to 16, 2011) German audio specialist beyerdynamic celebrates the launch of its new wireless flagship Opus 910. Designed for use either on tour or in fixed installations, the Opus 910 professional UHF wireless system offers the highest levels of reliability, audio and transmission quality and a package of features that is unique in its class.

A wide selection of receivers (single, double and quad channels), transmitters and interchangeable microphone heads are available for the system, plus an extensive range of accessories and the option for PC control for advanced system set-up. The receiver offers UHF bandwidth of 72 MHz and up to 2880 selectable frequencies per frequency range plus an automatic channel targeting function (ACT), making the system both future-proof and highly flexible, regardless of the venue it is used in. For the US, the system is offered in different frequency ranges between 482 MHz and 698 MHz.


Three receivers (single, dual and quad channel) are available, each offering 2880 freely selectable UHF frequencies per frequency range and a number of pre-programmed frequency groups to ease the set up of multi-channel systems.

The front panel of the receiver has a volume-controlled headphone output for monitoring individual receiver channels. All other system settings, such as squelch or the output level of the receiver are made centrally by the optimized jog wheel. The color LCD is easily readable from any angle and shows important system information such as frequency, group/channel, user name, field strength, audio level and remaining battery capacity of the transmitter. All receivers are fitted with an internal switching power supply (100-240 V), while the dual and quad channel receivers each contain an integrated antenna splitter.

Handheld Transmitters & Interchangeable Microphone Heads

There are two ergonomically designed handheld transmitters available for use with the Opus 910 wireless system each with different frequency ranges. The handheld transmitters feature a 36 MHz UHF bandwidth to reduce the number and strength of intermodulation products, guaranteeing optimum HF performance even in large multi-channel systems and difficult environmental conditions.

The handheld transmitters are equipped with an ACT interface to detect the carrier frequency from the receiver and set up the transmitter automatically. They also have a noiseless on/off switch and LCD showing channel/group and remaining battery capacity. Two 1.5 V AA alkaline batteries power the S 910 M (with metal housing) for over 20 hours, whilst the S 910 C (with plastic housing) has integrated charging contacts and is delivered with built-in rechargeable batteries (2 x Mignon AA NiMH) which provide an operating time of over 23 hours. The transmitter’s four microphone gain settings provide a high degree of flexibility in even the most diverse applications.

In order to maximize the flexibility of the Opus 910 system, both transmitters can be combined with five top quality interchangeable beyerdynamic microphone heads. Among others the RM 510, the world’s only ribbon capsule for wireless applications which delivers fantastic, unobtrusive vocal sound even on the loudest stages. The transmitter’s four microphone gain settings provide a high degree of flexibility in even the most diverse applications.

Pocket Transmitters

The TS 910 M (with metal housing) and TS 910 C (with plastic housing) pocket transmitters have been designed for use with clip-on lavaliere and headset microphones as well as electric guitars. The 4-pin mini XLR threaded plug can be used to connect either microphones or instruments and the input signal can be optimised using the receiver’s gain control. An onboard MT/GT setting lets you switch between microphones and instruments: in GT (guitar) mode, the gain control is inactive; in MT mode it is active. As with the handheld transmitters, the pocket transmitters also have a 36 MHz UHF bandwidth

The TS 910 C is fitted with two built-in rechargeable batteries (2 x Mignon AA NiMH) providing an operating time of over 23 hours. The batteries can be recharged using the SLG 900 battery charger with two charging compartments. Two 1.5 V AA batteries power the S 910 M for at least 20 hours.

The Opus 910 UHF wireless system is available as of February 2011. For more information please visit our website at www.beyerdynamic.com.
