Introduction

Thanks for choosing the Alesis M1Active 520/620 studio monitor. Alesis has a long history of making best-selling,high performance studio monitors and the M1Active 520/620 series builds upon everything we’ve learned from the past.

Our M1Active line of speakers (including the M1Active 520 and its “bigger brother,” the M1Active 620) were engineered from the ground up to be the perfect studio monitor. The biamplified design, active crossover, and carefully matched woofer/tweeter combination ensures perfectly accurate and uncolored playback of your music. These speakers are like a “sound microscope” that will allow you to hear every nuance of your mix and help you make better mixes.

We’ve made this quick start guide as short as possible, but please read it carefully. It teach you how to get the most out of your M1Active monitors.

We hope your new M1Active 520/620s will serve you well for many years.

Sincerely,

The People of Alesis

Front Panel

1. Power Switch/Clip Light- This bar turns blue when the M1Active 520/620 is powered up (the power switch is found on the top of the speaker) and the bar turns red when the speaker is being overloaded.

2. Acoustic Waveguide- Besides giving the speaker its devilishly good looks, our distinctive silver acoustical waveguide helps spread the tweeter’s high frequency sound evenly across your control room.

3. Tweeter- Our silk dome tweeter is designed to handle all frequencies above 3 kHz. This driver was carefully selected because of its ability to match the woofer and provide crystal clear sound withoutear-fatiguingharshness.

4. Woofer- Theultra-light,super-stiffmaterial found in our woofer cone helps the M1Active 520/620 deliver punchy bass and solid midrange (even at loud levels) without distortion.

Back Panel

1. TRS Input – This ¼” input accepts balanced “TRS” or unbalanced “TS” cables from your mixer, computer, or any other line level source. Both types of cabling will work, but we recommend balanced TRS (or XLR) cables since they give you better performance and lower noise (especially if you’re using longer cables).

2. XLR Input – This jack functions exactly the same way as the TRS input (see above), but it uses balanced XLR cabling.

3. Gain – This knob sets the input gain of the speaker. Use this knob to set a comfortable loudness level for monitoring.

4. Rear Port – The rear port augments the bass generated by the woofer to increase the low frequency SPL over that ofnon-portedspeakers.

Make sure this hole is not obstructed

since this will adversely affect bass response.

5.Acoustic Space Switch – This switch compensates for placement near walls and corners. Please see section titled “About the Acoustic Space Switch” for more on these settings.

6.Hi Boost – This switch allows you to tailor the speaker’s high frequency response to your control room. Please see the section “About theHi-BoostSwitch” for more about these settings.

Both XLR and TRS connectors have been provided for your convenience, but please use only one connection at a time to avoid overloading the inputs.

7. Mid Boost – This2-positionswitch provides a 2.5 dBwide-bandboost in the midrange at 1.8kHz. This has the effect of moving the soundstage “forward” closer to the mix position. Some engineers prefer to have this boost if the speakers are positioned farther than a few feet away. We recommend you try either the boosted “+” or bypassed “0” settings for a few mixes and select whichever one makes your mixes translate better.

8. Lo – Thishigh-passfilter switch lets you pick the point at which the speaker will roll off low frequencies. Many subwoofers roll off frequencies above 80 Hz, so if you want to use your M1Active 520/620 speakers with a subwoofer, set this switch to “80.” If you do not have a subwoofer, leave this set to the lowest number to let the M1Active 520/620 play its full range of sound.

Alternatively, you may want to hear how your mix will translate on smaller speakers (such as a TV, or radio). Set this switch to 80Hz or 100Hz (if you have a subwoofer, turn it off) and you’ll get a sense of how your mix will sound on smaller speakers with reduced bass output.

9.AC Voltage Selector – This2-positionswitch sets the AC input voltage for the speaker. US users should set this switch to“100-120V”whereas UK and most European users will need to set this to“220-240V.”

10.AC Input – This jack accepts standard3-prongIEC power cables. Make sure your AC Voltage Selector (see item #9 above) is set to the correct voltage for your country.

About the Acoustic Space Switch

The bass response of a speaker is greatly affected by the speaker’s proximity to walls. You’ll notice a buildup in bass frequencies as a speaker moves closer to a wall and even more buildup as the speaker moves closer to a corner. This happens because low frequencies radiate in all directions from the speaker cabinet and are reflected off your walls back into your control room. When this happens, the reflected sound mixes with the direct sound of the speaker itself resulting in “reinforced” bass.

Unlike bass frequencies, midrange and high frequency sounds are much more “directional” and only radiate forward. Because of this, the Acoustic Space Switch only deals with bass frequencies—thereis no need for high frequency compensation near walls.

We know that most home and project studios are set up under less than ideal conditions, so we’ve added the Acoustic Space Switch to help you optimize your speakers to your room.

If your speakers are farther than about 3 feet away from the walls of your studio, leave this switch set to the default “0” setting. This “full space” setting outputs bass normally.

If the speaker is up against a wall, set the Acoustic Space Switch to “2.” This setting is known as “half-space”and compensates for boosted bass due to your speakers being placed near one wall.

Finally, if your speaker is positioned in a corner, set this switch to “4.” This is known as a “quarter-space”setting and compensates for placement next to two walls.
