Sennheiser Lanza at IBC 2012 the digital system 9000

The IBC fair in Amsterdam has been the place chosen by Sennheiser to present the Digital 9000, an all-digital wireless system that can transmit completely uncompressed audio, free of artifacts and with excellent dynamics. The Digital 9000 includes EM receiver 9046, SKM transmitters 9000 handheld and/or SK 9000 pocket, and a complete range of accessories.

At the IBC fair, Sennheiser has presented Digital 9000, a digital wireless system that can transmit completely uncompressed audio, free of artifacts and with excellent dynamics. Aimed at broadcast professionals, musical theaters and high-profile live audio events, Digital 9000 sets a new benchmark in digital wireless transmission. The system, including EM receiver 9046, and SKM transmitters 9000 handheld and SK 9000 pocket, and a complete set of accessories, has been meticulously designed for the highest channel charges in today's increasingly dense frequency environment.

Kevin Jungk, Sennheiser Wireless Microphone Portfolio Manager, has manifested: “This system is a masterpiece, both digitally and wirelessly. Delivers unprecedented sound quality and ease of use. For example, Users will no longer have to calculate and bypass intermodulation frequencies but can conveniently place their transmit frequencies on an equidistant network “.

Ideal for the most diverse environments

The innovative digital wireless system is equipped with two transmission modes to meet any need and environment. High Definition mode (HD) will transmit completely uncompressed audio, artifact free, as if using a high quality wired microphone. Long Range mode (LR) It has been designed for difficult transmission environments with many sources of interference. Ensure maximum range with Sennheiser's patented digital audio codec. “This refined codec ensures audio quality that is superior to that of an FM system”, in explored Kevin Jungk. “These two modes make the Digital 9000 the most versatile digital wireless system on the market, and the one best adapted to the needs on the ground.”

Built-in ease of use

Plus IR synchronization between receivers and transmitters and a loop antenna for creating larger receiving systems, the Digital 9000 offers a number of unique features. First of all, the system does not generate intermodulation products – the high linearity of the entire system, from transmitters to antennas and receivers, and a special transmitter design make laborious intermodulation calculations a thing of the past. Transmission frequencies can simply be set on an equally spaced network.

The receiver also automatically measures the RF cable loss between the receiver and the amplifier and adjusts the gain accordingly.. “This makes the RF wireless system easier to operate for users with less RF knowledge.”, Kevin Jungk pointed out.

Optimal control

A large screen with clearly located controls is at the heart of the EM receiver 9046. Three display modes ensure that the RF or sound engineer has an optimal view of important parameters in live situations and can change settings quickly through an intuitive icon-based menu. Channels can be controlled through the headphone output, either individually or in any number can be heard together.

The EM receiver 9046 Modular is a central computer with capacity for eight internal receivers. The receiving system covers the UHF range of 470 a 798 MHz (328 MHz bandwidth). To easily integrate the system into an existing infrastructure, User can choose between transformer balanced analog or digital AES3 audio output modules, or a mix of both.

System tuning is facilitated by a built-in graphical spectrum analyzer to explore the RF landscape, and an RF level recorder for reception control and optimization of antenna positions. The receiver will also suggest the best transmission mode for the environment you are working in., and an appropriate gain will be automatically set to counteract RF cable losses. System antenna drives can be controlled via receiver, which is useful for installations with remote antenna positions.

The multi-channel receiver and transmitters can optionally use encrypted data transmission with randomly generated proprietary keys. This will protect a radio link against hijacking and threading.

The receiver stores up to ten complete system configurations so configurations can be easily recalled and repeated.

Powerful sound

A wide selection of four series microphone heads 9000 specific, in addition to all the wireless evolution G3 and capsules of the series 2000 will provide only the right sound for the SKM handheld transmitter 9000. The SKM handheld transmitter 9000 It is compatible with all G3 series wireless microphone heads and 2000, including Neumann KK capsules 204 y KK 205. This means that an artist's preferred sound can be easily transferred to the new system.. In addition to these capsules, The portable unit can be equipped with four Series capsules 9000 specific.

“The series 9000 would not have been complete without the sound of our most successful live capsule, and I am happy that the M.D. 9235 dynamic cardioid be part of our new digital system”, in internal Jungk Jungk. The rock 'n sound’ roll del MD 9235 is complemented by the transparency of the three permanently polarized condenser microphone heads, the M.E. 9002 (omni), the M.E. 9004 (cardioide) and the E.M. 9005 (super-cardioide). The condenser heads have low pop sensitivity and have extremely low handling noise due to the snowflake-shaped rubber suspensions above and below the actual capsules..

The robust SKM 9000 comes with a switching bandwidth of 88 MHz, and is available in black and nickel. Switch command mix versions are also available to facilitate communication between broadcast units or artists and their teams. How handheld devices transmit digitally, They do not use an expander and are free from the associated noise, ensuring purity of sound.

Versatile and light

The SK pocket transmitter 9000 It is easy to hide and easy to place; comes in a magnesium casing that combines maximum robustness with reduced weight. The transmitter can be used with any clip-on or headset microphone with a 3-pin Lemo connector and has a line input for guitars or other instruments. “How the system is capable of delivering wired audio, We've added a three-step guitar cable emulation to round out the perfect instrument sound”, in explored Kevin Jungk.

El S.K 9000 It is available in four different frequency ranges (switching bandwidth 88 MHz). A command switch is available as an accessory for communication between the equipment and the artists/journalists.

Selective and reliable

To protect the Digital 9000 against unwanted frequencies and interference, the AB antenna amplifier 9000 has been equipped with eight highly selective filters to allow only a specific frequency window to pass. Undesirable signals are thus blocked before the first active component, adding to the excellent overall system reliability. The filter can be adjusted manually on the amplifier or remotely via the antenna cable on the receiver.

El AB 9000 provides a maximum gain of 17 dB and is available as a stand-alone amplifier or integrated into the omni-directional antenna A 9000 and on the AD directional antenna 9000. Two amplifier versions (470 a 638 MHz and 630 a 798 MHz) cover the UHF range of the receiver.

Power supply

series transmitters 9000 operate on environmentally friendly rechargeable lithium-ion battery packs, with remaining operating time accurately displayed on both handheld and pocket transmitters, as well as in the receiver. ElSKM 9000 It is powered via the BA rechargeable battery pack 60, that powers the transmitter during 5,5 hours. El S.K 9000 pocket is powered by the BA 61, which has a duration of 6,5 hours. Operation with standard batteries is also possible.

The L charger 60 will recharge two BA 60 or BA 61 in any combination. It reaches the 70% charging in one hour and a full charge after three hours, with charging status indicated by three-color LEDs. Up to four chargers can be daisy-chained and powered through a single power supply.

Spectrum-efficient wireless connection

“In summary, Digital 9000 It is a meticulously designed cordless tool . Spectrum is a scarce resource, therefore, All parts of the system have been designed for the highest frequency efficiency. We have put a lot of effort into allocating the highest possible data rate for real sound transmission, ensuring the unparalleled audio performance of the Digital 9000. Because audio is what this is all about “, Kevin Jungk concluded.
