Part No. SW0616 Rev. D 0/09 ©2003-2009 LOUD Technologies Inc. All Rights Reserved. INTRODUCTION Thank you for choosing LOUD Technologies' Mackie active sound reinforcement speakers. The SRM50v is a redesigned version of our popular SRM50 active loudspeaker. With its newly designed Class-D Fast-Recovery amplifiers, high-output compression driver and new 10" neodymium woofer, it produces an even smoother sound than the original. SRM means Sound Reinforcement Monitor, and the SRM50v truly produces a studio quality sound in a sound reinforcement speaker. Our design goal was to build a sound reinforcement speaker with: 1. High precision, high output, and accurate playback. . Very wide, smooth dispersion of mid and high frequencies. . Ergonomically correct physical design for easy transport and set up. Through the combined resources of our top-notch mechanical and analog engineers, and our experienced transducer engineers at EAW, we were able to achieve our design goals in every aspect. The result is a sound reinforcement system equally at home in a concert setting, in the studio, impromptu concerts on the studio roof, in the cinema, or in a home theater. · The low-frequency amplifier also has a Dynamic Bass Boost circuit. Our ears are more sensitive to bass frequencies at high volume levels than at softer volumes. This unique circuit automatically reduces the low frequencies below 70 Hz as the volume of the speakers goes up. This results in improved efficiency for the low-frequency amplifier because it is not wasting power trying to reproduce frequencies we hear better at loud volumes. Instead, the power is used for the frequencies where it is needed, resulting in a louder sound. Warning: Although the amplifiers have these protection circuits, you must still make sure the LIMIT light is not blinking continuously. If it is, turn down your mixer faders, or preamplifier gain, or turn down the SRM50v LEVEL control. TheCrossover The built-in electronic crossover is a dB/octave Linkwitz-Riley design. Although more expensive than other crossover designs, the benefits provided by the LinkwitzRiley design have been well documented. These benefits include: · Absolutely flat frequency response throughout the bandpass, without the characteristic ripple near the crossover point exhibited by other designs. · The sharp dB per octave roll-off of the filters ensures that the transducers aren't reproducing frequencies outside of their capabilities. · The acoustic sum of the two driver responses is unity at the crossover frequency, resulting in perfect power response. · Our heroic engineers have worked carefully to ensure that the SRM50v also provides perfect phase response. This diligence has yielded phenomenal accuracy, even if you are standing 0 feet away.
