This combination of Class D and Class H amplifier technologies helps keep distortion to a minimum while reducing the need for massive heat dissipation. In fact, to a level low enough to eliminate the need for heavy heatsinks. The advantage of this unique combination of two-tier and Class D amplification has reduced extraneous heat to the point that EF500Ps can easily be used in any orientation (close to walls, floors and in close arrays with multiple cabinets). Competitive active loudspeakers, with large finned heatsinks, need to be operated vertically and with plenty of clearance (to ensure proper heat dissipation and ventilation). Since you have more versatility in regards to the orientation of the enclosure, the EF500P becomes ideal for flying in large clusters and in point-source concert sound systems. Yorkvilles designers took extra care making sure that in tight clusters overheating would not be an issue. Taking advantage of the design process, an opportunity was taken to tweak the electronics for maximum overall speaker performance and protection. Solutions were borrowed from our high-end TX-Series PA systems. The limiters used, at the input and crossover stages, are a complex combination of gain reduction and sweeping filters. If the EF500P is pushed to its maximum input/output levels, advanced filtering begins rolling off unnecessary subsonic frequencies. The processing also protects individual components ensuring failure free operation (even after long term operation at close to maximum output levels). The filter has a remarkable response time, less then 70ms, allowing the system to constantly be re-tuning itself. This makes sure the output is as clean, as loud and as clear as possible at any given moment. This is achieved without negatively affecting the overall sonic quality of the cabinet. This ensures that the essential part of the mix, like the vocals or solo instruments, come out clean and clear when the cabinet is being operated at the extremes of power and woofer excursion. Extremely fast and accurate limiting is in place to protect the speaker components. As a bonus, the EF500P has a built in mixer! This allows the loudspeaker to be used directly with a microphone and/or line source. The loop output allows additional active cabinets to be driven from one source (up to a maximum of 50 EF500Ps). If desired, you can combine a pair of the EF500Ps using the mixer inputs on each cabinet and coupling the loop outputs. In this example you would have an ideal presentation system. Two microphone inputs, two line inputs (optimized for CD, Cassette or laptop computer audio source), complete within two speaker cabinets. As mentioned, our active cabinets can be linked together, the limitation is that only three mixers can be active at any one time. This allows three Mic sources and six line sources available in an array of three or more cabinets). The microphone inputs have equalization and high pass filtering designed appropriately for vocal applications. The EF500P Active Full Range Loudspeaker Using the popular élite EF508 as a base, adding 800 Watts of bi-amped power and topping-it-off with advanced signal processing, the EF500P is destined to set the new standard for active loudspeakers. The woofer amplifier, or low frequency amplifier, amp delivers over 650 Watts to the 15 inch woofer. To reduce the overall weight of the amplifier section, the woofer amplifier uses Class D switching technology. A 150 Watt, two-tier linear technology, Class H amplifier drives the 2 inch titanium diaphragm horn driver. This allows the horn to produce clean transients while keeping up with the high output of the woofer. Two-tier amplifier technology isnt typically seen in a product like this, however we found the advantages (lower weight, more efficiency, higher headroom and lower operating temperature) made it a perfect choice for powering the top end.
