INTRODUCTION

Thanks for choosing the Alesis M1Active 320 USB desktop monitors – the perfect audio monitoring solution for desktop based audio systems.

Our M1Active line of speakers 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.

In addition to their superior speaker design, the M1Active 320 USB monitors feature a USB1.1 2in/2out computer audio interface. Simply plug the speakers into your computer and you are ready to go. Play audio from your computer or record into your computer from external sound devices connected to the inputs on the rear of the speakers – no additional audio devices necessary!

We’ve made this quick start guide as short as possible, but please read it carefully in order to get the most out of your monitors.

We hope your new M1Active 320 USB monitors will serve you well for many years.

Sincerely,

The People of Alesis

1.POWER – Use the included power cable to connect the speakers to a live power source. Make sure your AC Voltage Selector (see item #2 below) is set to the correct voltage for your country.

2.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.

3.OUTPUT TO LEFT SPEAKER – This is the audio connection to the left speaker. Use the included 1/8” cable to connect the right speaker to the left speaker.

4.USB (1.1) – Use the supplied USB cable to connect the speaker system to your computer. Note that the M1Active 320 USB speakers arePlug-and-Playso there is no additional driver installation necessary; the speakers should be ready to use as soon as they are plugged in.

5.1/8” STEREO INPUT – Use a 1/8” stereo cable (not included) to connect external sound sources to this input.

6.1/4” TS INPUTS – Use 1/4” TS cables (not included) to connect external sound sources to these inputs.

If you experience problems when connecting the speakers through a USB hub, we recommend connecting the speakers directly to your computer.

All three input options are mixed together as a stereo pair when recording your external sources into your computer.

7.RCA INPUTS – Use a stereo RCA cable (not included) to connect external sound sources to these inputs.

8.BASS BOOST – This2-positionswitch allows you to boost the speakers’ bass frequencies.

SPEAKER PLACEMENT

The placement of your speakers has a huge impact on how well they will perform in your studio.

Although nearfield studio monitors are designed to be more forgiving when it comes to placement, you should do your best to make sure they form an equilateral triangle relative to your head. In other words, make sure that each speaker is equally distant from both your head as well as the other speaker. Once each speaker has been placed, rotate the speakers slightly so that the drivers are pointing toward the engineer.

Take a look at the diagram on the right. Notice that the distance from the engineer’s head to each speaker is the same as the distance between the left and right speakers. Also note that the speakers are turned slightly so that the drivers are facing the engineer.

This is an ideal setup but if it is not practical (or possible) to do this, try to match this setup as closely as possible.

length sides.

SPEAKER HEIGHT

The ideal height for M1Active 320 USB speakers is so that the speaker is parallel to the ground and that the midpoint of the woofer and tweeter is at ear-height.

The diagram below demonstrates the ideal placement height of the speakers relative to the engineer. Notice that the engineer’s ears are directly between the woofer and tweeter.

WOOFER/TWEETER MIDPOINT

If possible, use speaker stands and move the monitors off of your desk (or meter bridge, if you are using a mixer). This usually results in better imaging since the monitor is decoupled from your desk and there is less chance reflected sound from the desk (or mixer) reaching your ears and smearing the imaging of your studio monitors.

CONFIGURATION UNDER WINDOWS

The M1Active 320 USB speakers are plug-and-playunder Windows XP/Vista so there is no special driver installation necessary. Simply power on the speakers, connect them to your computer’s USB port and all the necessary drivers will be automatically installed.

When you first plug the speakers into your computer, you will see a few messages similar to the one shown on the left. Allow the process to complete.

Once the process has completed, you will see the message displayed on the left. Your speakers are now ready to use.

You may choose to use the M1Active 320 USB speakers as the default audio output for your computer. To access your computer’s default audio preferences, go to Start Control Panel Sounds and Audio Devices and click on the

Audio tab.

You will see the screen displayed on the right.

To select the speakers as the default playback device, choose USB Audio CODEC underSound Playback.

To select the speakers as the default recording device, choose USB Audio CODEC underSound Recording.

Tip: While in Sounds and Audio Devices, we recommend turning off Windows system sounds so they do not interfere with your audio while in the middle of a session. You can do this by clicking on theSounds tab and selectingNo Sounds under the Sound Schemepull-downmenu.

ABOUT LATENCY & THIRD-PARTYASIO DRIVERS

“Latency” is the delay between the moment when audio is generated and the moment when you actually hear it. Higher latency means a longer delay.

The M1Active 320 USB speakers feature zero latency direct monitoring so you don’t have to worry about latency when monitoring input sources connected to the rear of the speakers. However, latency may become an issue when using software synths and instruments.

Generally, you want to keep latency as low as possible while still allowing your equipment to operate without glitches. Latency and buffering is usually adjusted in your software’s Preferences settings.

If you still experience too much latency or “lag” when using software synths and instruments, you might want to download one of the free and widely available ASIO (Audio Stream Input/Output) drivers from the Internet. In general, ASIO drivers may perform better and with lower latency since they create a more efficient communication between audio devices and software. You may download and install the free ASIO4ALL driver (PC) by visiting www.asio4all.com.

CONFIGURATION UNDER MAC OSX

The M1Active 320 USB speakers are plug-and-playunder Mac OSX so there is no special driver installation necessary. Simply power on the speakers, connect them to your computer’s USB port and the speakers should be ready to use immediately.

You may choose to use the M1Active 320 USB speakers as the default audio output for your computer. To access your computer’s default audio preferences, go to Applications Utilities anddouble-clickAudio MIDI Setup.

Under the Audio Devices tab, select

USB Audio CODEC as the default system input and output.

CONFIGURING YOUR DAW

Below are some tips on configuring your DAW to work with the speakers.

PLAYBACK

You may need to make sure that the speakers are enabled as an audio output device in your DAW, if you have not set them to be the default system audio output. This is usually done in the application’s Preferences dialog.

RECORDING

As you may have noticed, there are several inputs on the rear panel of the left speaker. These inputs allow you to record external sound sources directly into your computer. Note that the three sets of inputs are summed together before entering your computer as a stereo track. Therefore, it’s important to ensure that the volume of the input signal does not clip when using multiple external devices simultaneously.

To record from the inputs, make sure that the speakers are enabled as an audio input device in your DAW. This is usually done in the application’s Preferences dialog.

IMPORTANT: Make sure that software monitoring is turned off when recording from external sound sources. Otherwise, you may get feedback and distortion. To turn off monitoring on the recording channel, you can simply mute the channel in your software.
