UAX220v2 & UAX220-Mic User’s manual 5CONTENTS OF THIS PACKAGE Thank you for purchasing a Digigram UAX220v2 or UAX220-Mic USB audio device. The UAX220v2/UAX220-Mic package consists of the following components: * a UAX220v2 or UAX220-Mic * the user’s manual at hand. * a carrying case Feel free to visit our web site www.digigram.com to get more technical information, consult FAQs, and discover our complete and updated audio product line. 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 • 2 balanced analog mono line outputs∗∗, with a maximum output signal of +10 dBu • Switchable -12 dB input signal level attenuator • Switchable zero-latency direct monitoring of the inputs on the outputs via DSP 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 ¼ '' jack with knob for gain adjustment • A/D and D/A conversions up to 24 bits/48 kHz ∗ can be used with unbalanced signals ∗∗ electronically servo-balanced outputs provide automatic level adjustment to accommodate either balanced or unbalanced lines
D i g i g r a m 6 UAX220-Mic: Additional hardware features • 2 balanced∗ analog mono mic/line inputs • 2 knobs for left and right input gain adjustment, from 0 dB to 50 dB • 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). ∗ can be used with unbalanced signals
UAX220v2 & UAX220-Mic User’s manual 7HOW 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 <Start>, <Settings>, <Control panel>, <Sounds and Audio Devices>, tab ‘Hardware’. Select “USB Audio device” and click on “Properties”. The UAX will be displayed like this:
D i g i g r a m 8 Under Mac OS X Go to <System Preferences>, <Sound>. 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.
UAX220v2 & UAX220-Mic User’s manual 9CONTROLS 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 0 dB to +50 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 -12dB. 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.
D i g i g r a m 10 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 <Start>, <Settings>, <Control panel>, <Sounds and Multimedia >. 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.
UAX220v2 & UAX220-Mic User’s manual 11‘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. ‘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.
D i g i g r a m 12 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.
UAX220v2 & UAX220-Mic User’s manual 13CONFIGURATION 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.
