beyerdynamic reveals new wireless system and headphones
German audio specialist beyerdynamic revealed its new wireless Opus 910 professional UHF wireless system, designed for use on tour or in fixed installations.
Available for the system are a selection of receivers, transmitters and interchangeable microphones, plus a range of accessories and the option for PC control for advanced system set- up. The receiver offers a UHF bandwidth of 72MHz with up to 2,880 selectable frequencies per frequency range, plus an automatic channel targeting function (ACT). The system is offered in different frequency ranges between 502MHz and 790MHz.
Three receivers are available (single, dual and quad channel), each offering 2,880 freely selectable UHF frequencies per frequency range and a number of pre-programmed frequency groups. All receivers are fitted with an internal switching power supply (100-240V), while the dual and quad channel receivers each contain an integrated antenna splitter.
The two handheld transmitters feature a 36MHz UHF bandwidth to reduce the number and strength of intermodulation products. Both transmitters can be combined with five interchangeable beyerdynamic microphone heads.
The TS 910 M and TS 910 C pocket transmitters have been designed for use with clip-on lavaliere and headset microphones as well as electric guitars. The four-pin mini XLR threaded plug can be used to connect either microphones or instruments and the input signal can be optimised using the transmitter’s gain control. An onboard MT/GT setting lets users 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 36MHz UHF bandwidth.
Also unveiled at NAMM was beyerdynamic’s DT 1350 professional monitoring headphone featuring Tesla technology. The over-ear headphones feature ambient noise reduction and a maximum sound pressure level of 129dB. It also has removable, soft ear cushions, a flexible headband, and the ear cups swivel 90-degrees allowing ‘single-ear’ monitoring.
The manufacturer reports the Tesla sound transducers help achieve almost lossless magnetic flux. The Tesla principle sees the magnet mounted as a ring around the coil, allowing more energy to be directed to the membrane. Especially noteworthy is the ring shaped magnet, which allows our engineers to place a drill-hole directly behind the centre of the membrane in order to minimise disruptive resonances. The use of a special, multilayer membrane effectively suppresses unwanted partial vibrations and resultant distortion.
