【正品现货】美奇MACKIE SM450V2 12寸2声道有源音箱 The SRM350v2 retains the best of the original SRM design, including its signature Mackie Active architecture and renowned rugged durability. But with ultra-efficient switching power supplies, a lightweight neodymium woofer, an all-new compression driver and Class-D Fast Recovery amplification (165W LF/30W HF), the SRM350v2 packs way more power, clarity and punch. And its wide dispersion, outstanding bass extension and ultra-low distortion mean the SRM350v2 delivers pure studio monitor performance at full-on loudspeaker levels. Features 2-way bi-amplified, optimized Active loudspeaker system High-output, titanium dome compression driver 10-inch Neodymium long-throw low frequency transducer 165-Watt class-D, Fast Recovery Low Frequency amp; 30-Watt High Frequency amp Ultra-wide, smooth dispersion via HF waveguide Built-in phase accurate 24dB Linkwitz-Riley electronic crossover Electronic time correction, phase alignment and EQ for studio quality sound Mic/line input and pass-thru connector Lightweight for ultimate portability (26 lbs) Flyable, Pole mountable, Floor wedge-able The SRM Stands for Sound Reinforcement Monitor Over a decade ago, Greg Mackie and a dedicated team of engineers set out to create a portable loudspeaker that could deliver studio monitor sound quality. Unlike a relatively small, acoustically controlled studio where the sweet spot is well defined, live venues vary greatly, and most are far from acoustically balanced. Despite the challenges, after two years of extensive research and development, the first Sound Reinforcement Monitor was born—a loudspeaker that truly lived up to its name. The SRM350v2 continues the SRM350’s tradition of studio monitor sound quality—and trumps it—to deliver sound that makes any venue seem like a well-tuned studio. Ultra-Wide Dispersion Undoubtedly you’ve been to a show where the sound is all over the map—stand in front of the band, it sounds okay, but move a little to your left or right and all of a sudden you’ve got mud in your ears. When the SRM350v2 loudspeakers are on stage, no matter where you stand, you hear sound with impeccable stereo imaging, depth of field and definition—at full-on loudspeaker levels. This is due to the SRM350v2’s wide dispersion pattern, which is achieved through its High Frequency waveguide. Professional Grade Transducers The SRM350v2 has sounds even better than the original, in part, because of it’s premium transducers. The new 10-inch neodymium woofer has less mass and quicker response providing incredibly punchy response from such a small loudspeaker. Not to mention it is much lighter than a traditional ceramic magnet based transducer. Additionally, its titanium compression driver provides sparkle and clarity beyond the original design keeping its characteristic sound in-line with its big brother, the SRM450v2. The acoustic gurus out at EAW spent months and months tweaking these custom designed transducers so that the SRM350v2 would deliver the best sound possible in a small format box. Super low distortion thanks to Mackie’s own Class-D, Fast Recovery Amplification With its combination of Class D topology and Fast Recovery circuitry, the SRM350v2 operates with incredible efficiency, and delivers much more power and clarity. With this Class D Fast Recovery amplification, as we’ve lovingly (and creatively) dubbed the technology, the SRM350v2 handles maximum volume—and associated heat—with ease, so there’s no unwanted noise, and no thermal problems. Even after hours of sustained use at near-peak levels, your sound remains clean and your SRM350v2 keeps cool. Read more. Legendary Active Electronics In a passive loudspeaker setup, an external amplifier is connected to a passive crossover inside the speaker, which distributes frequencies to the transducers. Because power amps and transducers vary widely in sound and quality, trying to match the right power amp with the right speaker can be challenging, especially if you’re not a professional acoustic technician—or rolling in cash so you can hire one. Mackie\'s proven Active design does all the work for you. With the SRM350v2, you get a complete loudspeaker system, with complex electronics and carefully chosen components, all precisely tuned and tweaked to work together. The result is a loudspeaker with phenomenal sound quality and power, that’s completely plug-and-play—no EQ needed. Learn what’s inside. Built-in Protection Circuitry for Long Life Mackie knows that our Active loudspeakers are pushed hard—often to, or beyond, the limit. That’s why they have reliable protection circuitry built in to every one. The SRM350v2 employs a built-in limiter for less distortion at peak levels. And thanks to the advanced technology of its power supply and Class-D amp topology, the SRM350v2 is greater than 90 percent efficient—more of the power from your outlet goes straight to the transducer, without the power supply and amp giving off loads of heat. Less heat means better performance, and longer life. Versatile, Portable, Tough—And They Look Good, Too When designing the SRM350v2, Mackie considered every angle. From every angle is just how you can position it, too—pole-mount it from the bottom, fly it vertically or horizontally via its optional hanging bracket, or use it as a wedge monitor. With all this flexibility, it’s the most versatile portable Active loudspeaker around. And now moving it into place is easier than ever. Weighing in at just 26 pounds—now that’s light!—you’ll have more than enough strength left over to deliver an electrifying performance after loading in. Plus, the SRM350v2 retains its rugged, Mackie built-like-a-tank durability, thanks to the polypropylene cabinet—now in a tasty hue of Midnight Blue. So not only do you get a portable loudspeaker that sounds phenomenal, you get one that’s tough and portable for the road, and handsome enough for the show.
