M-One/USB Owner's Manual
Zero-latency USB Condenser Microphone w/ Headphone Output
Overview
The ART M-One/USB is a Class-A FET condenser USB microphone designed to connect directly to any USB 2.0 equipped computer or laptop. The 32mm gold sputtered/center-terminated wide diaphragm capsule delivers a full 20Hz to 20kHz frequency response, rivaling standard studio condenser microphones.
The ART M-One/USB offers the added convenience of an internal 24-bit / 96kHz digital conversion direct to the USB 2.0 output, making it ideal for software-based recording solutions or Podcasting. The M-One/USB operates on both Windows and Mac platforms.
What makes the M-One/USB unique is its integrated D/A converter, functioning as its own audio interface. This converter provides computer playback to the 1/8-inch headphone output jack, featuring integrated volume and mix controls on the microphone chassis. The volume control adjusts the overall listening level in the headphones, while the mix control allows users to blend computer audio (playback mix) with the microphone input (source) for a zero-latency recording solution.

Installation and Operation
Installing the M-One/USB is a simple procedure. As the M-One/USB is USB compliant, it can be used with either a Mac running OS-X or any PC running Windows XP or later. Simply connect the microphone to a standard USB port using the included USB cable for plug-and-play functionality. Control of the M-One/USB is managed through the standard audio interface controls within the Mac OS or Windows operating system.
Since signal levels can be adjusted via operating system preferences and recording software, it is advisable to be familiar with these controls. Therefore, it is recommended to follow the enclosed instructions for either Windows XP or Mac OS-X before installing any specific M-One/USB software driver.
Any 1/8-inch TRS headphone or earbud can be connected to the headphone output. It is advised to set the playback level to zero when connecting the microphone to any USB input while headphones are connected.
Setting up the M-One/USB in Mac OS-X
- Plug in the microphone. The LED will light up, indicating it is receiving USB power. The Mac will recognize the USB audio device and automatically install a universal driver.
- To select the M-One/USB as the computer's audio input, open System Preferences from the dock or the main Apple Menu.
- Next, open the Sound preference.
- Finally, click the Input tab and Output Tab to select M-One/USB.
Setting up the M-One/USB in Windows XP
(with Service Pack 2 - other versions may vary slightly.)
- Plug in the microphone. The LED will light up, indicating it is receiving USB power. Windows XP will recognize the USB audio device and automatically install the universal drivers.
- The M-One/USB is now recognized as a Windows audio device under the name USBMIC. To set it as the default device and change computer-controlled gain, access the Control Panel.
- Access Sounds and Audio Devices through the Control Panel.
- Select M-One/USB as the Sound recording device in the Audio tab window. You may also need to select the microphone within specific pro audio programs that require multiple device selections.
- To set the microphone Gain, click the Volume button. The Wave In window allows control over computer-controlled gain, pan, and microphone mute.
- Select M-One/USB as the Output Device in the Audio Tab Window and set the level.
Powering the M-One/USB
The M-One/USB is a condenser microphone, and like all condenser microphones, it has internal electronics requiring an active power supply. Traditional studio condensers are typically powered by a Phantom Power supply from a mixing console or external pre-amp. The M-One/USB receives its power directly from the USB bus. Simply connect the microphone to the computer's USB port, and it is ready to operate. The M-One/USB features a blue power LED that illuminates when USB power is present.
Microphone Placement
A cardioid polar pattern, like that used in the M-One/USB, is generally standard for most applications. A cardioid pattern delivers optimal results for most vocal recordings and a wide range of solo instruments. It provides full frequency response from the front of the microphone and benefits from the proximity effect (increased low frequency response when the microphone is placed close to the sound source*). A cardioid pattern also offers excellent noise rejection from the sides and back (180-degree position relative to the microphone), minimizing feedback and interference from other audio sources.
*Vocalists can leverage the proximity effect to enhance their performance, adding fullness and more 'bottom end' to their voice as they move closer to the microphone. Experienced vocalists can easily integrate this into their overall microphone technique. Experimentation with mic placement during the recording process is key.
In certain applications, it is advisable to use a pop filter, such as the ART M-WS, to reduce overly prominent "P" and "B" sounds.
