|At Winter NAMM show 2011 in Anaheim, California, beyerdynamic launched its new Opus 910 wireless flagship. Designed for touring and fixed installation applications, the Opus 910 professional UHF wireless system offers a wide selection of receivers, transmitters and interchangeable microphone heads, plus an extensive range of accessories and the option for PC control for advanced system set-up.
Offering an automatic channel targeting function (ACT). the receivers cover a UHF bandwidth of 72 MHz with up to 2880 selectable frequencies per range Different units provide a choice of frequency ranges between 502 MHz and 790 MHz. Three receivers (single, dual and quad channel) are available, each offering 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 can be accessedvia a jog wheel. The colour LCD is easily readable from any angle and shows relevant 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.
Two ergonomically designed handheld transmitters are 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 impact of intermodulation products to provie optimum HF performance in large multi-channel systems and difficult environmental conditions.
The handheld transmitters feature an ACT interface to detect the carrier frequency from the receiver and to 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 for more than 20 hours, while the S 910 C 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.
In order to maximise the flexibility of the Opus 910 system, both transmitters can be combined with five interchangeable beyerdynamic microphone heads. Among others the RM 510, the world’s only ribbon capsule for wireless applications. The transmitter’s four microphone gain settings provide flexibility in even the most diverse applications.
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.
Two 1.5 V AA batteries power the pocket transmitters for at least 20 hours. Optionally, the TS 910 C can be fitted with TS 900 AP rechargeable battery pack providing an operating time of more than 23 hours. The rechargeable battery pack can be recharged with the SLG 900 charging unit.
