      Smart Active Monitor (SAM) provides remarkably accurate monitoring

      These days, it's not unusual for an engineer to work in a small, less-than-perfect acoustical environment. Genelec's Smart Active Monitor (SAM) technology takes this into account by allowing the 7380A active subwoofer to automatically calibrate its level, timing, and equalization to your room, ensuring that you hear the original nuances of your source accurately, without color or distortion. By using the highly-intuitive Genelec Loudspeaker Manager (GLM) software, you can control your entire network, giving you a highly-flexible computer-controlled system of monitors and subwoofers.

      Smooth, controlled bass from Laminar Spiral Enclosure (LSE)

      Developed by Genelec's award-winning R & D team in Finland, the 7380A active subwoofer's radically innovative Laminar Spiral Enclosure (LSE) design dramatically alters how high-level, low frequency acoustic energy is delivered to any critical listening space. The result of LSE technology is the elimination of port turbulence-caused acoustic non-linearities, which means a smooth-sounding flow of low-frequency energy from the 7380A's rigid tuned enclosure.

      Protected by Genelec's Intelligent Signal Sensing (ISS) power management system

      Thanks to Genelec's Intelligent Signal Sensing (ISS) power management system, you never have to remember to shut down your 7380A active subwoofer again. ISS constantly checks for input signal. After a while, if ISS doesn't detect anything, it switches your 7380A over to a low-power sleep state, safeguarding your gear and sparing you the wasted electricity.

      What Genelec Says...

      Delivering high SPL and extended LF response, the 7380A offers power, clarity and flexibility in equal measures.

      High SPL, low distortion

      Providing a level of performance normally associated with much larger enclosures, the 7380A subwoofer offers both high power and high SPL, with an extended low-distortion LF response and flexible bass management options. Comprehensive connectivity ensures that the 7380A is equally at home in stereo or multichannel environments, making it perfect for music, post, film or broadcast applications that demand powerful, dependable LF reproduction in a surprisingly compact form factor.

      Configure, calibrate and control

      The 7380A works closely with our GLM software, which allows all monitors and subwoofers in a system to be configured, calibrated and controlled. Offering access to advanced system auto-calibration and management, GLM’s powerful room compensation features enable the 7380A to be optimised for a wide range of acoustic environments, and permits both centralised and distributed bass management modes to be employed.

      Active crossover operating at low signal levels.

      Audio electronic crossovers allow the audio signal to be split into separate frequency bands that are separately routed to individual power amplifiers, which are then connected to specific transducers optimised for a particular frequency band. Active crossovers come in both digital and analogue varieties. Genelec digital active crossovers include additional signal processing, such as driver protection, delay, and equalisation. Genelec analogue active crossover filters contain electronic components that are operated at low signal levels suitable for power amplifier inputs. This is in contrast to passive crossovers that operate at the high signal levels of the power amplifier's outputs, having to handle high currents and, in some cases, high voltages. In a typical two-way system the active crossover needs two power amplifiers — one for the woofer and one for the tweeter. Using the active approach enables frequency response adjustments and optimisation of the full loudspeaker system, placed in various room environments, without expensive external equalisers. The end result is a simpler, more reliable, efficient, consistent and precise active loudspeaker system.

      The active crossover design offers multiple benefits:

      • The frequency response becomes independent of any dynamic changes in the driver's electrical characteristics or the drive level.
      • There is increased flexibility and precision for adjusting and fine-tuning each output frequency response for the specific drivers used.
      • Each driver has its own signal processing and power amplifier. This isolates each driver from the drive signals handled by the other drivers, reducing inter-modulation distortion and overdriving problems.
      • The ability to compensate for sensitivity variations between drivers.
      • The possibility to compensate for frequency and phase response anomalies associated with a driver’s characteristics within the intended pass-band.
      • The flat frequency response of a high-quality active loudspeaker is a result of the combined effect of the crossover filter response, power amplifier responses and driver responses in a loudspeaker enclosure.

      Bass Management System handles multichannel low frequency content.

      The principle of bass management is that the bass content of the main channels and the Low Frequency Effect (LFE) channel are directed and reproduced only by loudspeakers capable of handling them, whether they are main system loudspeakers or one or more subwoofer(s). In stereo reproduction, signals from 20 Hz to 20 kHz need to be replayed. Large multi-way monitoring systems will reproduce such a wide bandwidth evenly. With multichannel audio, professional and consumer audio systems must also be able to reproduce audio between 20 Hz and 20 kHz for each channel. To achieve this, main monitors, subwoofers and crossover electronics should work together. A Bass Management system uses either analogue electronic circuitry or software based filtering which will filter low frequency information from the main channels and route that information to one, or more, subwoofer feed. The dedicated LFE channel can also be monitored via that subwoofer and added to the low frequencies of the other main channels. Therefore, the Bass Management’s basic and main goal is to ensure that the entire audio bandwidth of all channels can be accurately monitored.

      The benefits of the Bass Management System:

      • The subwoofer extends the system frequency response down the lower limit of the audible range
      • Monitor can produce a higher maximum sound level when not reproducing low frequencies
      • Optimized low frequency reproduction by selecting adequate subwoofer location; monitors can also be placed more freely
      • Subwoofer’s output are aligned in level and phase with monitors allowing flat and accurate reproduction down to 19 Hz and across the crossover point
      • LFE channel output level (0 or +10 dB re. main channels) can be selected for accurate reproduction depending on the source type
      • The ability to bypass the subwoofer allows to evaluate the audible impact of the subwoofer

      Intelligent Signal Sensing (ISS™) for power consumption reduction in stand-by mode.

      Introduced early 2013, Genelec’s Intelligent Signal-Sensing technology has been developed to meet with both European Union ErP Directives and Genelec's own ambitious sustainability standards. The Intelligent Signal Sensing, ISS™ circuitry tracks the signal input of the loudspeaker and detects if it is in use. If the ISS circuit does not find any audio on the input for a period of time, it sets the loudspeaker to a low-power sleep state and the loudspeaker will consume less than 0.5 watts. When an input signal is detected, the loudspeaker immediately turns itself on. Additionally an ‘ISS Disable’ switch is located on each product’s back plate next to the other room response controls. First, when the mains power switch of the loudspeaker is set to 'ON', the ISS™ auto-start function (low-power sleep state on/off) of the loudspeaker is active. If this function is not desired, the ISS™ function can be disabled by setting the 'ISS Disable' switch on the back panel to 'ON' position. In this mode, the monitor is only powered on and off using the mains power switch. Note that the mains power switch will always turn the monitor off completely.

      Highly efficient Laminar Spiral Enclosure (LSE™) provides accurate low frequency reproduction.

      The demands placed on subwoofers over the last years have increased substantially to the point where traditional design concepts are no longer valid. For Genelec, in order to achieve the absolute best performance possible, bold initiatives must be taken. Drawing on years of acoustic research and knowledge, Genelec's engineering group accepted the challenges placed upon them in the beginning of the 21st Century. The totally unique, curvilinear shape of the LSE™ Series Active Subwoofer enclosure is the revolutionary patented result of their efforts. All of the Genelec LSE™ series subwoofers feature this innovative Laminar Spiral Enclosure™ (LSE™) bass reflex cabinet. It provides excellent laminar flow characteristics with minimal turbulence noise and enables an optimal packing of a very long reflex tube into a small space. The learnings from the LSE Technology are also utilized in the reflex port design of our aluminium enclosure products. The spiral-shaped design yields an extremely rigid enclosure exterior while also forming the subwoofer's integral port. The fact that one is part of the other means that air flow in and out of the enclosure's interior through the port is totally unrestricted. This results in an extraordinarily accurate and responsive low-frequency system with measured second and third harmonic distortion levels typically better than 30 dB below the fundamental. When combined with Genelec stereo and multichannel bass management active electronics, the LSE™ Series Subwoofers provide a low-frequency listening experience like no other. The result is a product range with impeccable technical performance: The Genelec LSE subwoofer range is unique, complete, functional, different from any other products on the market, and consistent.

      Each transducer is driven by its own optimised amplifier.

      Audio electronic crossovers allow to split the audio signal into separate frequency bands that can be separately routed to individual power amplifiers, which are then connected to specific transducers optimised for a particular frequency band. In a typical 2-way loudspeaker system, the active crossover needs two power amplifiers — one for the woofer and one for the tweeter. The power amplifiers are connected directly to the drivers of an active loudspeaker, resulting in the power amplifier’s load becoming much simpler and well known. Each driver-specific power amplifier has only a limited frequency range to amplify (the power amplifier is placed after the active crossover) and this adds to the ease of design.

      The active design principle offers multiple benefits:

      • The power amplifiers are directly connected to the speaker drivers, maximising the control exerted by the power amplifier’s damping on the driver’s voice coil, reducing the consequences of dynamic changes in the driver electrical characteristics. This may improve the transient response of the system.
      • There is a reduction in the power amplifier output requirement. With no energy lost in the passive crossover filter components, the amplifier power output requirements are reduced considerably (by up to 1/2 in some cases) without any reduction in the acoustic power output of the loudspeaker system. This can reduce costs and increase audio quality and system reliability.
      • No loss between amplifier and driver units results in maximum acoustic efficiency.
      • Active technology can achieve superior sound output vs. size vs. low frequency cut-off performance.
      • All loudspeakers are delivered as a factory aligned system (amplifiers, crossover electronics and enclosure-driver systems).

      Sophisticated drive unit protection circuitry for safe operation.

      When working in critical audio production environments it is essential that monitoring systems remain reliable and functional at all times. One of the main reasons behind Genelec’s excellent success in broadcasting environments is the reliability of our products and a key element behind the reliability is the internal protection circuitry found in all products since 1978. The protection circuitry prevents driver failures by detecting signal levels, and in case of sudden peaks or constantly too high levels, taking the signal level down automatically. Of course this feature does not affect the sound quality in any way when working within the specifications of the loudspeaker, but only prevents inadequate input signals from breaking the loudspeaker.

      Protection circuitry features and benefits:

      • Reduces the output level when required, (e.g. when driver voice coil temperature reaches the safe limit), which highly improves system reliability.
      • Appropriate protection circuitry design in every loudspeaker and subwoofer enables the maximisation of system output sound level.

      Precise room response compensation for optimizing in-room performance.

      The interaction between room acoustic and loudspeaker radiation is complex. Each room changes somewhat the monitor’s response in a unique way, e.g. reflective vs. damped rooms, or placement against a wall vs. on a stand away from the walls. All Genelec loudspeaker systems feature room response adjustments to compensate for the room influences and retrieve a flat frequency response at the listening position.

      Smart Active Monitor (SAM™) Systems

      Genelec SAM Systems offer a comprehensive, solution-oriented, intelligently networked product range which all feature Genelec Loudspeaker Manager (GLM™) software and its automatic calibration system called AutoCal™. Genelec AutoCal provides the industry’s first integrated process for complete automated measurement, analysis, and adjustment of every monitor on the GLM control network. The system measures the response in the listening area and applies relevant compensation in the low and low-mid frequencies to minimise the detrimental room acoustic anomalies as well as the differences between various listening positions. AutoCal also aligns relative levels, time-of-flight, as well as adjusts correct crossover phase (called AutoPhase) for all subwoofers on the network. glm2 screenchots The Acoustic Response Editor provides accurate graphical display of the measured response, filter compensation and the resulting system response for each monitor, with full manual control of acoustic settings.
