Klein+ Hummel, a 100% Sennheiser subsidiary, introduces two new subwoofers: O 810 and O 870                            Since 1967, Klein + Hummel’s active studio monitors have developed a reputation for their pioneering engineering techniques and low distortion reproduction. More recently, a profusion of developments in transmission technologies has increased the demands placed on professional monitoring systems. As a result, modern production facilities now require highquality monitoring systems that can accurately reproduce anything up to the latest 7.1 discrete high definition formats. The O 810 and O 870 meet these new demands. It is the perfect compliment to Klein + Hummel’s increasingly extensive range of monitors and can be used either as unit dedicated to reproducing the LFE channel, or as a way to provide low-frequency extension and increased maximum SPL for the main loudspeakers. “The O 810 and O 870 now make it possible to assemble flexible monitoring systems for different sized of studio, with a smooth and uniform response that ranges from less than 20 Hz to greater than 20 kHz” says Andrew Goldberg, Product manager Studio Systems. The built-in 7.1 Channel High Definition Bass Manager™ is compatible with all formats from mono through to the latest 7.1 high definition systems, such as Blu-ray and HD-DVD. Eight channels of analog, or an optional 8-channel 24-bit 192 kHz digital input card, ensure flexible interconnectivity for modern studios. Four-mode LFE channel processing ensures maximum compatibility across all formats. 4th order crossovers and flexible acoustical controls allow for seamless system integration. Built-in volume control allows for centralized system replay level adjustment independent of the source, and the electronics can be remote located to reduce cabling. The latest amplifier technologies and acoustical components have been used to ensure the most accurate sound reproduction possible. Robust drivers, a rock-solid cabinet, and carefully designed ports guarantee a tight, articulate, and distortion-free low frequency reproduction down to 18 Hz, even at high replay levels. Using the sum output, Plane Wave Bass Array™ (PWBA™) techniques can acoustically improve lateral consistency in the listening area. The O 810 and O 870 can be used in music, broadcast, and post production studios for tracking, mixing, and mastering. They may be positioned next to a wall or flush mounted into a wall, and can be mixed freely in multichannel systems with other loudspeakers from the Klein + Hummel range. An extensive range of accessories further enhance the flexibility of the system.

K+H offers clean and strong power amplification with the K8 system advantage Klein+Hummel introduces the KPA series of audio power amplifiers ideally suited to drive the largest and most demanding reinforcement applications. Power factor corrected and operating at levels as high as 6000 Watts into 2 Ohms down to models providing 1100 Watts into 8 Ohms, this series covers the full range of reinforcement needs. Unique to K+H is the ability to daisy chain amplifiers together using a single category 5 cable for both digital audio distribution and remote control and monitoring of all amplifier functions including load monitoring. The head end of the K8 digital audio distribution system may be fed with an expanding selection of inputs including the choice of Ether Sound, AES3 digital or analog. Installed sound product manager Dave Theis points out the advantage, “K8 only requires a single control connection to Ethernet or USB to monitor and control all the amplifiers in multiple equipment locations.” Any of 16 audio channels may be selected at the amplifier or switched via remote control through the K8 system from K+H. The KPA series is highly efficient and offers a powersaving standby mode putting long term ownership costs at a minimum.

K+H introduces K8-AESI16 digital audio input device Klein+Hummel expands the innovative K8 digital audio distribution system with AES3 digital audio inputs. The K8-AESI16 puts 16 audio channels from AES3 onto the K8 bus with a single rack unit box accepting any sample rate from 32 kHz up to 192 kHz. The K8 bus may then be run up to 200 meters over Category 5 cable for distribution directly to K8 enabled power amplifiers, K8 self powered speakers or to K8 analog output devices feeding other system components. According to Dave Theis, product manager for installed sound, “K8 makes Cat5 distribution of digital audio available to a wide range of system sizes in a way that does not require extensive training to implement.” K+H successfully launched the K8 system concept in Frankfurt last year as a cost effective method to distribute 16 channels of digital audio out to multiple locations with a total system latency of 0.5 milliseconds. The flexibility and compatibility of the system is now further increased with the addition of the K8-AESI16 and allows the system to be fed from any device with AES3 standard outputs.

Klein+Hummel to launch new monitor speakers At 121st AES Convention, San Francisco, Klein+Hummel introduces two new monitor speakers, the O 300 nearfield monitor and the M52 control monitor which is designed for mobile studios and all applications where space is an issue but quality monitoring still indispensable. Following the O 300 D with both, analogue and digital inputs, the O 300's model number already implies that the new speaker builds on the features of the O 300 D - actually, it provides the same acoustic and electronic qualities without the digital inputs of its sister product at a different price level. O 300 stands for a compact active reference monitor with accurate, uncolored sound, superb transient response, and ideally shaped waveguides. The speaker has been fine-tuned through extensive computer simulations and countless listening tests resulting in precise room-matching capabilities reproducing sound absent of colorations, precise bass response, picture-perfect dispersion patterns, and a stunningly real soundstage. The M 52 is the powered control monitor of choice for small studios and sound trucks. Featuring a linear frequency response, the M 52 also convinces by its size of 120 x 173 x 116 mm. The M 52 fits many applications in recording and broadcasting applications, it also works on 12V DC power supply. Optionally, the M 52 is available with digital inputs (AES/EBU and S/P-dif).
