Flexible, reliable and future-proof with superior audio quality
04. January 2011
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, transmitters and interchangeable microphones heads are available for the system as of March 2011, plus an extensive range of accessories and the option for PC control for advanced system set-up. The receivers's UHF bandwidth of 72 MHz offers 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. The system is offered in different frequency ranges between 502 MHz and 790 MHz. (Further frequency ranges on request.)
Three receivers (single, double 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 optimised jog wheel. The colour 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.
There are two ergonomically designed handheld transmitters available. 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.
Interchangeable Microphone Heads
In order to maximise the flexibilty of the Opus 910 system, both handheld transmitters can be combined with five top quality interchangeable microphone heads:
- RM 510 - Ribbon, Cardioid
An absolute highlight. The RM 510 microphone head is the world's only ribbon capsule with cardioid polar pattern and delivers fantastic, unobtrusive vocal sound, typical for all beyerdynamic ribbon microphones, even on the loudest stages.
- CM 930 - True Condenser, Cardioid
A top class vocal microphone. Because vocal microphones are typically used at close distance, the close miking effect has been compensated to achieve completely neutral transmission of even the most delicate vocal nuances. The subtle treble boost ensures a sound pattern that is open and detailed without ever becoming obtrusive.
- DM 960 - Dynamic, Hypercardioid
An exceptionally powerful microphone with a distinctive close miking effect, which moves singers firmly into the foreground. The hypercardioid polar pattern ensures maximum gain-before-feedback.
- DM 969 - Dynamic, Supercardioid
A reliable all-rounder for both vocals and speech: excellent sound, extremely robust and high gain-before-feedback.
- EM 981 - Electret Condenser, Cardioid
The EM 981 capsule delivers a high level of clarity in conferences, addresses, reports and live radio and television broadcasts.
The TS 910 M (with metal housing) and TS 910 (with plastic housing) pocket transmitters have been designed for use with clip-on lavalier and headset microphones as well as electric guitart and bass 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 transmitters' gain control. As with the handhelds, the pocket transmitters also have a 36 MHz UHF bandwidth.
Switching Bandwidth and Intermodulation
You may be wondering why our transmitters have a frequency range of 36 MHz, even though our receivers are equipped with a range that is twice as big at 72 MHz. The answer is simple – to ensure optimum HF performance even in large multi-channel systems and difficult environmental conditions.
Our decision to reduce the frequency range in our transmitters reduces the number and strength of unwanted intermodulation products, which in turn reduces the likelihood of possible "interfering frequencies". This allows more systems to be operated in parallel and free of interference within the predefined bandwidth. This is especially beneficial in difficult wireless environments, for example in the vicinity of DVB-T (Digital Video Broadcasting Terrestrial) transmitters.
The pre-programmed, interference-free frequencies of the receiver are matched to the frequency range of the transmitter, offering group and channel spacing ideally suited for multi-channel operation.
Receivers are available in the frequency ranges:
- 502-574 MHz
- 574-646 MHz
- 646-718 MHz, and
- 718-790 MHz.
Transmitters are available in the frequency ranges:
- 502-538 MHz and 538-574 MHz
- 574-610 MHz and 610-646 MHz
- 646-682 MHz and 682-718 MHz
- 718-754 MHz and 754-790 MHz
