Launched at prolight+sound show 2006, Frankfurt, Genelec also showcased its 8200 and 7200 DSP Series Monitors at 121st AES convention in San Francisco. Built on the solid foundation of Genelec’s 8000 MDE and 7000 LSE Series products, the Genelec 8200 Series bi-amplified active monitors and 7200 Series active subwoofers are designed for users who want a network speaker system that can be set up, measured, analysed and calibrated quickly. A direct result of years of in-the-field acoustical research and testing with key customers as well as analysis in Genelec’s R&D facilities, the 8200/7200 DSP Series Monitors employ the company’s proprietary DSP (Digital Signal Processing), GLM (Genelec Loudspeaker Manager software) and AutoCal (Automated Calibration software) technologies yielding a robust and reliable speaker system that maximizes ease of integration into the end-user’s studio environment.
Genelec has utilized sophisticated digital signal processing in the 8200 Bi-amplified monitors and 7200 Subwoofers to allow for all standard AES/EBU formats of digital audio. The 8200/7200 Series will accept sampling rates ranging from 32 kHz to 192 kHz. The 8200 Series will also accept traditional analogue signals and perform with all the features and benefits of Genelec 8000 Series products.
The Genelec Loudspeaker Manager (GLM) software is a sophisticated computer program (Windows XP or Mac OS X platforms) providing connectivity/control for all loudspeakers on the GLM Control Network. As many as 25 of the 8200 loudspeakers and 5 of the 7200 subwoofers are definable and controllable via standard CAT5 cabling. GLM allows multiple custom User Setups with all settings and functions able to be stored in GLM setup or directly to each loudspeaker. An intuitive Wizard guides the user through complete cabling connections and speaker labeling. Rapid Cabling setups for the most common system configurations, as well as Manual Cabling setups for customized system configurations, are available. The user may also customize groups for both channels and speakers. Solo/Mute functions are available, too. Volume can be controlled via computer, third party USB device or custom console. In addition, there is Video Display compensation for inherent video delays in digital video devices.
Genelec’s automated system calibration software, AutoCal, supplies an integrated process for complete automated measurement, analysis and adjustment of every speaker on the network to correctly integrate and maximize each speaker within the mixing environment. Employing self-generated test signals and a Genelec 8200A calibration microphone (included), AutoCal calibrates the correct acoustical alignments for all the loudspeakers and subwoofers on the GLM Control Network. AutoCal uses a sine wave sweep (chirp) generated by each loudspeaker and subwoofer. This sweep is recorded using the microphone, over one or more positions, and the impulse response calculated. AutoCal then determines the correct acoustical settings for each loudspeaker and subwoofer to obtain flat frequency response at the listening position, or, over an area, equal timing arrival from all loudspeakers to the primary listening position as well as proper alignment of the subwoofer(s) in terms of output level and crossover phase.
included measuring microphoneSinglePoint and MultiPoint microphone positions provide measurement for one-, two- or three-position mixing environments. When AutoCal has optimized the Room Response Control settings, the results can be saved into the System Setup file. Further adjustment is then possible using the Acoustical Settings Editor. The Interactive Response Editor provides accurate graphical display of the measured response, filter compensation and resulting system response for each loudspeaker on the network. The 8200 Series Bi-amplified Monitors can utilize four notch filters and four shelving filters while the 7200 Series Subwoofers utilize four notch filters, plus Bass Roll Off controls.
The DSP Series is comprised of two bi-amplified active monitors. The 8240A utilizes a 6.5-inch woofer and 3/4-inch tweeter set into Genelec’s Advanced Directivity Controlled Waveguide (DCW). The free-field frequency response is 48 Hz to 20 kHz (±1.0 db). Peak SPL per pair is 115 dB driven by a pair of 90 Watt amplifiers for each driver. The 8250A has an 8-inch woofer and 1-inch tweeter set into the DCW with a free-field frequency response of 38 Hz to 20 kHz (±1 db). Peak SPL per pair is 120 dB driven by 150 Watt LF, and 120 Watt HF amplifiers. Both models are fully compatible with the GLM and proprietary Genelec loudspeaker control network, as well as the 7260A, 7270A and 7271A Active Subwoofers, and can also be used independently of the network. All drivers are magnetically shielded.
The 7260A subwoofer features a single 10-inch proprietary driver with a 120 Watt power amplifier, frequency response of 19 Hz – 85 Hz (± 3 dB), and ability to deliver SPLs of 108 dB @ 1 meter. The 7270A incorporates a single 12-inch proprietary driver with a 250 Watt power amplifier, frequency response of 19 Hz – 85 Hz (± 3 dB), and ability to deliver SPLs of 112 dB @ 1 meter. The 7271A features dual 12-inch proprietary drivers with a 500 Watt power amplifier, frequency response of 19 Hz – 85 Hz (± 3 dB), and ability to deliver SPLs of 118 dB @ 1 meter. All models are designed for precise monitoring of 24-bit/192 kHz AES/EBU digital audio signals. They are fully compatible with the GLM/proprietary Genelec loudspeaker control network and 8240A and 8250A DSP loudspeakers.
