Active Loudspeaker Monitor User Guide
English EX66 • User Guide EX66 Features English Introduction Congratulations on your purchase of M-Audio’s EX66 reference monitor. Recording engineers and music producers around the world rely on M-Audio reference monitors to ensure their mixes are accurate. The EX series active monitors from M-Audio improve upon that reputation as a top-of-the-line solution for the most demanding applications.
What’s with the Two Silver Woofers? � Bass-Reflex Port The EX66 uses a midwoofer-tweeter-midwoofer (MTM) vertical array configuration to provide an extraordinarily versatile sound radiation pattern (degrees of arc for the sound wave, vertically and horizontally). Consider the following: conventional 2-way speakers in a stereo setup require that you listen to them in a fairly narrow “sweet spot” (where you position yourself at the apex of an isosceles triangle with the speakers).
Setting up your EX66 Monitors Important - The EX66 works best in the vertical position. If you place the speaker horizontally, you will lose many of the benefits of the MTM design and the sound image will deteriorate. They’re only speakers, so how hard can it be... right? Depending on your experience with vertical array speakers, it may not be that simple. The following section can give you useful information on how to get the best acoustic response out of your EX66 monitoring setup.
Finally, because of the EX66’s wide horizontal radiation pattern, you do not need to “toe in” the speakers. Having the speakers point straight, rather than turned in toward the listener, should provide the proper ratio of center-fill to soundstage width. The XLR and 1⁄4” TRS inputs are summed, so you can use both inputs at the same time. Important - If you’re using an XLR plug, make sure you feed it into the “XLR” � input in the “Analog” portion of the EX66 rear panel—and NOT the AES/EBU input.
EX66 • User Guide Now that you’ve connected your audio signal input, you can power on your EX66 monitors using the following procedure: 1) Connect the supplied AC power cord to the IEC connector �� . 2) Plug the other end of theAC power cord into a grounded outlet that is configured to correspond with the Voltage Selector switch �� . 3) Turn the Volume knob �� all the way down. 4) Flip the Power switch �� to the On position.
5) High Frequency Adjustments Did You Know? The High Freq switch �� allows you to make your EX66 monitors sound more “bright” or more “dark,” depending on your preference. Technically speaking, the three-position switch activates a gain/attenuation circuit in the tweeter channel. It offers 2dB of boost or cut starting at the 2.56kHz crossover point—similar in concept to the high-frequency adjustment function found in the classic BBC monitors.
EX66 • User Guide Protecting Your Ears In order to safeguard your EX66 from accidental damage, we’ve built in some protection mechanisms. As a musician, composer, or engineer, your hearing is one of your most valuable assets. So we’d like to advise you about protecting yourself from high sound pressure levels (SPLs), which can lead to hearing loss.
