FEATURES

UAX220v2/UAX220-Mic is a stereo audio interface for USB ports (compatible with USB ports 1.1 and 2.0). It is powered via USB, and does not require any driver installation (as it is compatible with the USB Audio specification 1.0).

Main hardware features

• 2 balanced analog mono line inputs *, with a maximum input signal of +22 dBu for UAX220v2, +10 dBu for UAX220-Mic
• 2 balanced analog mono line outputs **, with a maximum output signal of +10 dBu
• Switchable -12 dB input signal level attenuator for UAX220v2, -20 dB for UAX220-Mic
• Switchable zero-latency direct hardware monitoring of the inputs on the outputs

Note: the input monitoring is mixed on the output with the sounds played by the application.

• Possibility to switch the input monitoring to mono mode "left channel + right channel"
• Possibility to record both inputs mixed
• 1 stereo headphone output on female 14 " jack with knob for gain adjustment
  • A/D and D/A conversions up to 24 bits/48 kHz

UAX220-Mic: Additional hardware features

• 2 balanced * analog mono mic/line inputs with a maximum input level of +10 dBu
• 2 knobs for left and right input gain adjustment, from +20 dB to +55 dB with switchable -20 dB input attenuation
  • Left and right 48 V phantom power switches for static microphones

Software features

UAX220v2 and UAX220-Mic comply with the USB Audio specification. Therefore, and depending on the operating system used, they are compatible with WDM DirectSound, ALSA, and CoreAudio. Furthermore, it is possible to use a third-party ASIO driver (Asio4all, Ploytec).

HARDWARE REQUIREMENTS

• A USB port (standard 1.1 or higher)
• Minimum Apple Macintosh configuration: PowerMac G3, G4 or G5 with 128 MB RAM
• Minimum PC configuration: Pentium III (or equivalent), 256 MB RAM.

Supported operating systems

• Windows XP
• Mac OS X
• Linux

HARDWARE INSTALLATION

Connect the UAX220v2/UAX220-Mic to the USB port (USB 1.1 or 2.0) of your computer. It will then automatically be detected by the operating system and its driver will also be automatically installed.

Note: If you have several USB peripherals connected to your computer, they may consume more energy than the USB port can provide. In this case, disconnect some of these peripherals.

SOFTWARE INSTALLATION

Your UAX220v2/UAX220-Mic does not require any driver installation, because it meets the USB Audio 1.0 standard, which is supported by your operating system (Windows XP, Mac OS X, Linux).

HOW TO CHECK THE INSTALLATION

Once the UAX220v2/UAX220-Mic is connected to the USB port of your computer, you can check the accessibility of its inputs/outputs as described hereafter.

Under Windows

Go to , , , , tab 'Hardware'. Select "USB Audio device" and click on "Properties".

The UAX will be displayed like this:

MIDI music playback Default device: Microsoft GS Wavetable SW Synth Volume... About... Use only default devices OK Cancel Apply

Under Mac OS X

Go to , . The UAX will be displayed as follows.

Under Linux

The parameters of the UAX220v2/UAX-Mic are accessible from the audio application of your choice.

CONTROLS

UAX220v2 and UAX220-Mic feature switches and faders for manual controls as well as adjustments via software.

Manual controls

- 48V (UAX220-Mic)

These two switches (one per input channel) allow enabling/disabling the 48 V phantom power for condenser microphones. This power supply is activated on a channel when the corresponding LED is lit.

• In1 and In2: (UAX220-Mic)

These two knobs allow adjusting the analog gain on each input, from +20 dB to +55 dB. The “Peak” LEDs light up when the input level is too high.

- Pad

This switch permits to attenuate the analog input signal level by -12 dB for UAX220v2, -20 dB for UAX220-Mic. The attenuation is active when the corresponding LED is lit.

• 1+2

This switch allows adding up the left and right input channels. The summation is active when the corresponding LED is lit. The signal arising from the summation is then available on the left and right channels to be recorded, and/or to be sent to the outputs, if the monitoring is activated.

- Monitoring On

This switch allows sending the input monitoring signal to the outputs (modified by the various input adjustments)

- Monitoring Mono

This switch allows monitoring on the summation of left and right channels on the outputs. The summation is active when the corresponding LED is lit.

Digital recording of the stream played

With “Monitoring Mono” activated and the “Monitoring On” disabled, the UAX allows to record the played stream without passing through the analog inputs/outputs. This makes it possible, for example, to record an Internet broadcast using an application such as Windows Media Player.

• Headphones out level adjustment

The knob marked with a headphones symbol allows adjusting the audio level on the headphones output. This setting does not affect the line outputs.

Software controls

Control Panel under Windows

To control the levels of your UAX220v2 or UAX220-Mic, use the Volume Control application. To open this application, double-click onto the loudspeaker icon in the Windows task bar. In case this icon is not displayed in the task bar, go to , , , .

On the 'Volume' tab, check the box "Show volume icon in the task bar".

The UAX220v2/UAX220-Mic offers Volume and Mute controls for the outputs. These controls are not available for the inputs.

Properties Mixer device: UAX220-Mic Adjust volume for ○ Playback ○ Recording ○ Other Show the following volume controls: ✓ Speaker ✓ Wave □ SW Synth □ CD Player OK Cancel

'Loudspeaker' volume control

The fader ‘Loudspeaker’ modifies the analog output gain of the UAX220v2/UAX220-Mic. The applied gain varies from -60 dBr to +10 dBr, by steps of 1 dB. These controls are applied to both line and headphones outputs.

The check box 'All mute' in the loudspeaker section allows muting/unmuting the outputs of your UAX220v2/UAX220-Mic.

Speaker Options Help Speaker Balance: Volume: Mute all Wave Balance: Volume: Mute UAX220-Mic

'Wave sounds' volume control

The volume and mute controls are applied to the audio stream read by the application. Therefore it is a digital gain adjustment.

Mac OS volume Control Panel

The fader 'Output volume' modifies the output level of the D/A converters of UAX220v2/UAX220-Mic.

The 'Mute' checkbox next to the volume control allows to mute/unmute the UAX220v2/UAX220-Mic outputs.

CONFIGURATION

UAX Manager

The UAX Manager application (available on the Digigram web site) allows UAX220v2/UAX220-Mic to

• either work at a fixed frequency (32 kHz, 44,1 kHz or 48 kHz), or at the frequency defined by the application
  • to process the samples at 16 or 24 bits.

Default factory setting is: frequency fixed at 48 kHz, 24-bit sample resolution.

In the “sampling frequency set by audio application” mode, if the frequency of the application is other than 32 kHz, 44,1 kHz or 48 kHz, then the UAX works at 48 kHz and sample rate conversion is performed by the audio layers of the operating system.

In the “Frequency fixed” mode, sample rate conversion is performed by the audio layers of the operating system if the frequency of the application and the frequency of the UAX are different.
