dspInstrument spDAQ Balanced - 2 Channel Measurement Front End

The dspInstrument spDAQb™ is a 2 channel USB bus-powered data acquisition front end optimized for balanced audio measurements. It has industry-leading signal/noise performance and distortion performance since it relies on state-of-the-art audio data converters. However, unlike audio soundcards, each input and output level is stable and calibrated for accurate measurements. The sampling rate can be as high as 192k.

The input gain can be selected independently for each channel.

Two balanced audio outputs are available with selectable gain.

The dspInstrument spDAQb is intended to be used with a host computer using USB3 as a power source. From the host computer point of view, the dspInstrument spDAQb looks like a USB Audio Class 2 sound card. An external Windows application and DLL manages the special control settings for level, calibration, and other settings. This Windows DLL allows you to integrate control settings seamlessly into your custom application. The UAC2 driver supports both Windows Multimedia Extensions (MME) and ASIO (Steinberg Audio Stream Input/Output).

MSRP is $750.
