Features

Front Panel

1. Tweeter: This driver outputs the audio

signal’s high frequencies.

2. Woofer: This driver outputs the audio

signal’s low frequencies.

3. Headphone Output: Connect your 1/8” (3.5

mm) stereo headphones to this output. Note

that while headphones are connected to

M1Active 330 USB, you will not be able to

hear sound out of your speakers until the

headphones are disconnected.

4. Signal Light: This light will illuminate when

the monitors are powered on.

5. Volume: This knob will be in its left-most

position when the monitors are powered off.

Turn it clockwise until it clicks to power

them on. Turn the knob further to adjust the volume on both monitors.

Rear Panel

6. Bass Reflex Port: These ports discharge

very-low-frequency signals to enhance the

monitor’s overall bass response. Make sure

these ports are not obstructed.

7. Input from Right Speaker: This is the

audio connection from the right monitor.

Use the included 1/8” (3.5 mm) TS cable to

connect this input to the output to the left

speaker on the other monitor.

8. Output to Left Speaker: This is the audio

connection to the left monitor. Use the

included 1/8” (3.5 mm) TS cable to connect

this output to the input from the right

speaker on the other monitor.

9. Power Input: Use the included power cable to connect this input to a power outlet.

10. Inputs: Connect your line-level audio interface, turntable, mixer, etc. to any of these three inputs.

• the 1/8” (3.5 mm) input, using a standard 1/8” (3.5 mm) TRS stereo cable

• the two 1/4” (6.35 mm) inputs, using standard 1/4” (6.35 mm) TRS or TS cables

• the two RCA inputs, using a standard RCA stereo cable

Note: During the first 2-3 hours of playing music (or other sound sources), M1Active 330 USB speakers

will go through a "break-in" period. During this time, their components will improve in sound quality,

allowing them to deliver their best performance.

11. USB Port: Use a standard USB cable (included) to connect this USB port to your computer. The

monitors should be ready to use as soon as they are connected; no additional drivers are necessary.

12. Bass Boost: Use this switch to turn the monitors’ enhanced bass response on or off.

Operation

Computer Setup

The M1Active 330 USB monitors are plug-and-play, so there is no special driver installation necessary. Simply

power on the monitors, connect them to your computer’s USB port and all of the necessary drivers will be

automatically installed. To enable your M1Active 330 USB monitors to receive audio from your computer, follow the

instructions below for your computer’s operating system.

Latency (Windows only)

“Latency” is the time it takes for your computer’s soundcard to process incoming data and output a sound.

The lower your latency is, the faster your computer will respond to commands and output sound. If you

experience too much latency, we recommend the free ASIO4ALL (Audio Stream Input/Output) driver for

Windows at asio4all.com. ASIO drivers generally perform better than the computer’s built-in drivers and

with lower latency since they create a more efficient communication between audio devices and software.

1. Download and install the free ASIO4ALL driver from asio4all.com. This will allow for low-latency

performance.

2. Double click the installer file (.exe). Follow the on-screen prompts to install the included low-latency

ASIO4ALL driver.

Placement

Place your monitors 3–5 feet (1–1.5 meters) apart from each

other and from you so that they form an equilateral triangle with

your position when viewed from above. Angle them slightly

inward so that the drivers face you.

In general, we recommend placing them at least 3 feet

(approximately 1 meter) away from the nearest wall and other flat

surfaces.

Tips:

Make sure your studio and monitors are equidistant from the

walls on either side of it. This helps ensure proper symmetry of

your stereo signal.

If possible, set up your studio and monitors in the “front” third of

the room. This helps prevent the reflections of peak frequencies

from building up.

If possible, place your monitors on speaker stands instead of

directly on your desk. Desks tend to resonate sympathetically at

low frequencies and may adversely affect the monitors’ bass

response. If you cannot use speaker stands, try placing the

monitors on isolation pads to acoustically “decouple” the

monitors from the desk.

Use other sound-absorbent materials (carpeting, foam, etc.) to

prevent reflections in the room.

Height

Position the monitors so that they are parallel to the ground and

that your ears are between the midpoint of the woofer and the

tweeter.

Orientation

If possible, place the monitors in their upright position; avoid

laying them on their sides. The woofer and tweeter are vertically

aligned and will provide the best performance when the monitors

are upright. Placing them on their sides may create strong

reflections from nearby surfaces resulting in spectrally

unbalanced sound.

If your monitors must be oriented horizontally due to space or

line-of-sight considerations, place them so that their tweeters are

on the “inside” to improve imaging.
