Surround Sound Processor. Professional Integration Features All XTRA Series amplifiers have an ultra low inrush current draw to prevent power circuit overload that occurs when multiple amplifiers are switched on simultaneously. This feature eliminates the need for power sequencing in systems with multiple amplifiers in large centralized equipment racks, and prevents other equipment from experiencing power interruption from associated power surges. These amplifiers also feature very low thermal dissipation under full load, to keep racks and equipment cabinets cool. XTRA Series amplifiers accept balanced and unbalanced input signals and include recessed, detented level controls located on the rear panel to prevent tampering. These controls allow for adjusting audio system gain structure, or setting individual levels for each zone. Additionally, the XTRA Series includes multiple protection circuits that momentarily activate when an abnormal condition, such as overheating, is detected. An advanced, automatic clip limiter protects speakers from clipping distortion.

3 Features to watts rms output power for high or low impedance speaker systems The XTRA Series is designed for a wide variety of applications, from classrooms and boardrooms to multi-purpose rooms, auditoriums, and open spaces. They deliver ample power for distributed voice reinforcement speaker systems with a large number of high impedance speakers, or large, high-powered program speaker systems. Professional grade signal-to-noise and THD+N performance The XTRA Series delivers professional grade performance with at least db signal-tonoise ratio and.% THD+N or less. Convection cooled, fanless operation XTRA Series amplifiers do not require internal fans or vents for cooling, ensuring quiet, reliable operation. They generate substantially less heat than similar power amplifier designs, making them ideal for rack-mount applications. Patented CDRS - Class D Ripple Suppression CDRS is an Patented technology that provides a smooth, clean audio waveform and an improvement in signal fidelity over conventional Class D amplifier designs. CDRS eliminates the high frequency switching ripple characteristic of Class D amplifiers, a source of RF emissions which can interfere with sensitive A/V equipment such as wireless microphones. ENERGY STAR qualified and UL verified The XTRA Series is a family of ENERGY STAR qualified amplifiers and energy efficient products that conserve energy and reduce costs. Each XTRA series amplifier has earned the Energy Efficiency Certification from UL Environment to verify that stringent ENERGY STAR qualifications have been met. Auto power-down with fast power-up XTRA Series amplifiers meet ENERGY STAR. qualification requirements with an auto power-down feature that automatically places the amplifier into standby after 5 minutes of inactivity, dramatically reducing power consumption. They quickly return to full power status in less than one second upon signal detection. Power factor correction The XTRA Series features power factor correction technology that smooths out the high peak currents of the amplifier s current draw, minimizing the presence of high frequency harmonics on the AC power line, and therefore preventing audible artifacts from being transmitted to other audio equipment in the system. Automatic clip limiter Detects actual onset of clipping by comparing input and output waveforms. Gain is automatically reduced with a slow attack and fast release to eliminate clipping. This advanced limiter design protects the speakers from clipping distortion and offers superior sonic characteristics compared to limiters that use signal compression. Multiple protection circuits Activate during output shorts, thermal overload, or DC faults to prevent damage to the amplifier and speakers. Remote standby port Enables the XTRA Series amplifiers to be remotely powered down when not in use, reducing operating cost. Ultra low inrush current - no need for power sequencing Allows multiple XTRA Series amplifiers to be powered on simultaneously without overloading power circuits. This eliminates the need for power sequencing. Rear panel recessed, detented level controls Provide attenuation of input signals for adjusting audio system gain staging as well as multizone applications. They are located on the rear panel to prevent users from tampering with level adjustments. Small rack-mountable U enclosure With the capability to deliver full-sized amplifier power in one quarter to one half the size of many comparable power amplifiers, the XTRA Series reduces rack space requirements for many installations.

4 Cost of Ownership XTRA Series power amplifiers are engineered for efficiency to help integrators and their clients save money in many ways. XTRA Series amplifiers consume less power and cost less to operate than conventional amplifiers. They also generate much less heat than conventional amplifiers, which can further lower energy costs since less rack and room cooling would be needed. Additionally, XTRA Series amplifiers weigh less and therefore incur lower shipping fees. Comparing an XPA, with an efficient Class D design, to a conventional Class AB amplifier, used in many applications, demonstrates the advantages the XTRA Series provides. OPERATIONAL EFFICIENCY AND REDUCED POWER CONSUMPTION With an energy efficient power supply, Class D amplification, and automatic power-down, the XPA uses far less energy than a conventional Class AB amplifier. Operating at / power, the XPA is 5% efficient while a conventional amplifier with the same output power is only % efficient. This translates to wasted energy. POWER IN / POWER OUT XPA Conventional Amplifier watts 7 watts 5 watts watts The conventional amplifier does not have a standby mode and consumes 7 watts in idle mode when not amplifying a signal. The XPA, however, draws just watts in idle, then goes into standby, drawing only. watts. When factored over a year of service, the numbers really add up. The conventional amplifier would consume 57% more energy! In a four amplifier system where XTRA Series amplifiers replace conventional amplifiers, the facility operator saves. megawatt-hours of consumption annually, translating to a yearly savings of over $7. EFFICIENCY 5% % Efficiency, / output at ohms: The XPA sends more of the input power to the outputs than the conventional amplifier, which wastes more energy as heat. XPA POWER CONSUMPTION 5,9 W-hrs 5,5 W-hrs hours / year at / power, 7 hours at idle or standby Conventional Amplifier 57% more Annual power consumption at ohms: Low idle power consumption and auto power-down allow the XTRA series amplifiers to draw less power than conventional amplifiers. REDUCED SHIPPING COSTS The XTRA Series amplifiers weigh as little as one-fourth as much as competitive models. They employ lightweight, energy efficient power supplies and do not require fans or heavy toroidal transformers. For this reason, they are also housed in much smaller enclosures. These factors translate to savings in shipping costs for the XTRA Series. For example, the XPA features an enclosure one-quarter the size of a competitive U, 9 inch ( cm) wide model, and is also one-fourth the weight. As a result, the estimated cost to ship the XPA by ground, from our headquarters in Southern California to the midwestern U.S., is nearly 5% less than the cost to ship the competitive model. PRODUCT WEIGHT GROUND SHIPPING XPA Conventional Amplifier.5 lbs (. kg) lbs ( kg) $.5 $. Shipping costs from the U.S. West Coast to the U.S. Midwest: This example demonstrates how the advantages of the XTRA Series lightweight Class D design result in lower shipping expenses.

5 Cost of Ownership THERMAL EFFICIENCY Convection cooled XTRA Series amplifiers generate little heat and do not require fans. In comparison, competitive power amplifiers typically produce enough heat to require internal fans and forced air ventilation in a rack. In a small A/V control room with a full rack of amplifiers, all running continuously around the clock, it is likely that the ambient temperature will have to be maintained through air conditioning. XTRA Series amplifiers run much cooler than conventional amplifiers, and can be installed in credenzas and other spaces where amplifiers normally would not be placed due to limited air circulation. They can be sufficiently cooled by the ambient temperature and air flow within the room, substantially reducing the need for forced air circulation. AT / POWER IDLE (OR IDLE IF N/A) XPA at / Power XPA watts watts. watts 7. BTU/hr BTU/hr BTU/hr Conventional Amplifier.5 watts 7. watts BTU/hr 9 BTU/hr NO 7. watts 9 BTU/hr Thermal dissipation: The convection cooled XTRA Series dissipates much less heat into racks and equipment rooms to keep cooling costs down. Conventional Amplifier at / Power Over the course of a year, the conventional amplifier will waste as much as,7,59 BTUs while the XPA will waste as little as,57 BTUs. In a four amplifier system where XTRA Series amplifiers replace conventional amplifiers, the facility heat load is lower by a difference of,99,79 BTUs annually. IR photography demonstrates how cool the XTRA Series operates compared to similar power amplifiers, lowering energy costs associated with cooling equipment racks. SPACE EFFICIENT SMALL ENCLOSURE With smaller enclosures and less heat generated, installation of XTRA Series amplifiers will require less rack space than other amplifiers. The XPA, for example, fits within a rack space one-fourth the enclosure size of a competitive model. Furthermore, many amplifiers have vents on the upper and lower panels, and require adequate space above or below for ventilation. Because the XPA runs cool and does not require ventilation, up to four of them can fit into the same space required for a competitive model. The U, half rack width XPA versus a competitive U, full rack amplifier allows more amplification to be installed in smaller spaces to save installation equipment costs.

7 HEADER_CATEGORY_ALL_PAGES header_main CDRS - Class D Ripple Suppression CDRS is a patented technology from that dramatically improves signal fidelity over conventional Class D amplifier designs. It delivers a smooth, clean audio waveform by eliminating the high frequency switching ripple characteristic of Class D amplifiers. This ripple is also a source of RF emissions, which can interfere with sensitive A/V equipment such as wireless microphones. Elimination of Switching Ripple Improves Audio Performance The switching ripple at the audio output distorts the audio waveform and may impact audio performance. As a result, the switching ripple can compromise the capability of a Class D amplifier to deliver natural sound reproduction. s advanced Class D design incorporates patented CDRS technology, providing pure, high fidelity audio output. Reduced EMI Emissions Conventional Class D amplifier designs emit significant amounts of EMI - electromagnetic interference emissions that often impact sensitive nearby electronic equipment. s CDRS technology eliminates EMI interference problems and produces a clean, ripple-free output. To learn more about this technology, download the white paper at Tek T Trig d M Pos:.s CH.V M 5. µs CH - 9.9kHz In a conventional Class D amplifier the switching ripple is present on the output audio waveform as a superimposed high frequency ripple.

20 Amplifier Technology White Papers offers a collection of white papers written by engineers that discuss the technologies behind XTRA Series amplifiers. Download these and more at Class D Amplifier with Ripple Steering Class D amplifiers are used for their high efficiency, but they have some undesirable characteristics, one of these being the residual switching frequency ripple. This paper shows a method of switching frequency ripple reduction by means of ripple steering. With this technique a second output is constructed, into which the switching ripple is steered, substantially relieving the main output from a major artifact of Class D operation. Power Supply Regulation in Audio Power Amplifiers Audio power amplifiers have typically been supplied power by the simplest possible means, usually an offline supply with no line or load regulation, most commonly based on a line frequency transformer. Even modern amplifiers utilizing switchmode power supplies are usually designed without line or load regulation. The exception has been made for high-end audiophile amplifiers. The pros and cons of a regulated power supply are investigated. Power Factor Correction in Audio Applications Switched-mode power supplies are increasingly common in audio power amplifiers, and are desired for their relatively small size and weight, as well as high efficiency. This article provides an introduction to power factor correction, which substantially reduces AC harmonics and prevents noise impact on other A/V products in the system.
