External USB sound card

The Andrea USB-SA-1 adds a 5.1 channel digital audio interface to any desktop or laptop through a standard USB 2.0 connection. It delivers CD-quality 48 KHz sample rates and a 40 dB signal-to-noise ratio for clearer playback and recording. The thumb-drive sized housing measures 5.0 in x 4.0 in x 1.0 in and weighs 0.032 kilograms for easy transport.

Bundled PureAudio software suite

The included Andrea PureAudio Voice Solutions software enables the hardware noise-reduction technology on Windows 98 SE, 2000, XP and Vista. Mac OS 9 and 10 are supported for basic audio functions without the software package. A power and data LED on the unit confirms active operation and driver communication.

Check your headset and OS compatibility

The 3.5 mm microphone input expects a 2.2k Ohm, 5 VDC powered microphone while the speaker output drives 8 to 32 Ohm mono or 16 to 32 Ohm stereo headsets. Verify that your current headset matches those impedance and power requirements before ordering. Users on Windows versions newer than Vista or on macOS releases beyond OS 10 should confirm driver availability separately.

Questions about this item

Will the 3.5 mm microphone jack need a specific headset impedance to work reliably?

The microphone input provides 5 VDC through a 2.2 kOhm load and accepts a 3.5 mm tip connection; headsets from 16 to 32 Ohms stereo or 8 to 32 Ohms mono are supported.

At 48 KHz sampling, what is the first limitation during long recording sessions?

The signal-to-noise ratio is specified at 40 dB, so background hiss becomes the limiting factor before sample-rate headroom does.

How much heat or fan noise does the USB adapter produce when left on all day?

The thumb-drive-sized unit has no fan and draws power only from the USB 2.0 port, so it runs silently with negligible warmth.
