User manual ELECTRO-VOICE 605 DATASHEET

[. . . ] As a vital part of the X-Array concert sound system, the P3000's performance was proven on the biggest world tours of the time, including the Rolling Stones and AC/DC. Moving forward into the 21st century, the IRIS-Net-controlled P3000RL followed suit on the largest tours and events of the era: LIVE8, Live Earth, Metallica, Kenny Chesney, and Foo Fighters, to name a few. As direct descendants of the legendary P3000, Q Series amps take Electro-Voice's unique amplifier design philosophy to a new level of performance, power, efficiency, and value. Innovative Class-H power With Q Series' efficient Class-H design, the permanent voltage rail is designed to cover the average music signal, rather than permanently supplying the voltage for maximum output power. [. . . ] If dynamic peaks require a higher output voltage, the voltage rail is switched to the maximum. This process saves up to 50% of the power consumption found in conventional amplifier design, and results in a dramatic reduction in heat output. Q Series combines the sonic excellence and ruggedness of its Precision Series predecessors with Class-H innovation, all in a compact and affordable package. Q1212 With 2 x 1200W @ 4 Ohms / 2x 1800W @ 2 Ohms, the Q1212 offers the horsepower to challenge the legendary P3000. It provides the same power from a 2U case at modest weight, making it a perfect subwoofer or high-power top drive for Phoenix, Tour X, and ZX3/ ZX5 systems or system combinations. Q99 With 2 x 900 Watts @ 4 Ohms / 2 x 1250W @ 2 Ohms, Q99 can seriously serve as combined top & sub drive for most club-sized systems, such as Tour X or QRx. Q66 A versatile workhorse, with 2 x 600W @ 4 Ohms / 2 x 900W @ 2 Ohms. Q66 has plenty of power to drive a huge variety of speaker systems, including Sx300, ZX4, Sb122, etc. Q44 The base model, providing 2 x 450 W @ 4 Ohms / 2 x 650W @ 2 Ohms. An excellent choice for small tops and utility loudspeakers, such as ZX1, Sx Series, or EVID Series. Audio Performance While many people understand there are tremendous differences between professional loudspeakers, many also tend to think that amplifiers are only differentiated by the amount of output power they provide. Electro-Voice amplifiers serve to prove that there are also audible differences. . . Dynamic Headroom Amplifier power and distortion figures are typically specified with sine wave signals. While these technical explanations appear very complex, they are clearly audible. Take a Q Series amplifier and crank it up ­ you'll hear the difference immediately! Protection Package & Dynamic Limiter There are many good-sounding amplifiers available; however, for an amp to be considered the world's best requires unparalleled reliability in real-world applications. Q Series amplifiers benefit from decades of professional amplifier design, and all the expertise that has made EV amps the concert/touring standard is built into Q Series. Our complete protection package includes sophisticated circuits against overheating, short circuit, DC output voltage, HF oscillation, back EMF (Electromotive Force), and destructive peak current. Furthermore, Q Series amps also protect your valuable loudspeakers with built-in dynamic limiters, preventing dangerous output clipping. The limiters immediately reduce amp gain when dynamic headroom is pushed to the limits at maximum output, keeping distortion below 1% in a situation that can otherwise cause a signal to clip, which is often fatal for woofers and drivers. Maximum amp output signal Unclipped Signal Maximum output signal - input signal at input sensitivity, THD<= 0. 1% Clipped Signal Input signal 10dB above input sensitivity - clipping output can destroy loudspeakers Dynamic Limiter Signal Same 10dB above input sensitivity input signal - the dynamic limiter keeps the THD to 1% max, thus preventing the speakers from damage. Q-Series Amplifiers & Connectivity Whatever application you choose, you can be sure your Q Series amp is prepared: · Both inputs have a paralleled loop thru XLR output to route signal to other amp inputs · Besides the usual channel A & B outputs via Speakon connectors (on pin 1+/1-), output A carries the signal of channel B as well (on pin 2+ / 2-), providing an easy drive option for biamped speakers · Parallel & Bridge Mode option switches provide additional functionality with minimized cabling requirements · An additional switchable LPN (Low-Pass Notch) filter provides extra tonal fundament and kick, with protective LowCut for using smaller passive 12" or 15" cabinets without additional subwoofers Amplifiers & Speaker Systems Recommended System Setups Speakers Sx80 Sx100+ Sx250 Sx300 Sb1 22 ZX1 ZX1 + Sb1 22 ZX3 ZX4 ZX5 TX1 22FM 1 TX1 22+Tx1 1 181 TX1 152FM TX1 152+Tx1 181 TX2152 TX2181 PX2152 PX2152 (LF/HF) Px21 22 (LF/HF) PX2181 PX1 22M 1 PX1 152M QRx1 2 1 QRx1 15 QRx1 18S QRx21 2 QRx153 (LF/MH) QRx218S requires DC-One Signal Processor The above recommendations are for typical use, also depending upon cabling, number of cabinets used, etc. Q 44 Q 66 Q 99 Q1212 High Freq.
