Audio Testing Hardware
Listen’s SoundCheck software works with any professional quality soundcard and most brands of audio testing accessories for flexibility in your system configuration.
To simplify hardware selection, and to offer tight integration with the software, Listen also offers its own test hardware. Listen’s own hardware was developed specifically to meet the needs of the audio test market, including all the functionality that you need for audio test, and eliminating unnecessary functionality. True plug and play integration accelerates startup and configuration, and its often multifunctional nature reduces the number of hardware items that you need, simplifying setup and system footprint.
Audio Testing Hardware
Audio Interfaces
Listen’s multi-function audio interfaces optimize your measurements with features including:
- High-resolution measurements with a low noise floor, flat frequency response, and sampling rates up to 192 kHz
- SCM and IEPE power to avoid an additional microphone power supply
- Fast and automatic configuration with TEDS compatibility and automatic signal path calibration
- Exclusive software control to eliminate accidental level adjustment and maintain test integrity
- Robust, error-free cabling with a single USB connection to the computer, internal signal routing, and BNC inputs
- Advanced software-hardware integration features such as autoranging to maximize SNR.
AudioConnect 2
Our low-cost, portable interface is ideal for headphone testing and cost-sensitive production line applications. It features two inputs, two outputs and a headphone output. The USB connection to the computer also provides power, making it ideal for field applications.
AmpConnect 621
The 6-in, 2-out interface is packed with functionality with 6 inputs, 2 line outputs and one amplifier output to power speakers and artificial mouths. Impedance measurement and digital I/O are also included. This interface is ideal for automotive applications with a 6 microphone array, speaker testing, and any measurement where an artificial mouth or speaker is needed, e.g. smart device testing.
AudioConnect 8×8
Our newest 8-in, 8-out interface excels for high channel-count applications. Multiple units can be connected for synchronous expansion up to 32 input and output channels, and S/PIDIF I/O allows an additional two channels for mixed analog/digital signals.
Other Hardware
SC Amp Audio Test Amplifier
SC Amp is the world’s only dedicated audio test amplifier. It has low distortion and a low noise floor, and features integrated impedance measurement, fixed gain to reduce calibration errors, and DC voltage offset support.
SoundConnect 2 Microphone Power Supply
SoundConnect 2 is a 2-channel microphone power supply and conditioning amplifier. It powers SCM/electret or IEPE microphones or accelerometers, and is also available with a 200V polarization option. It offers low self-noise, a wide frequency response, adjustable gain control, and user-selectable filters.
SCM Measurement Microphones
SCM measurement microphones are robust, ¼” free field measurement microphones designed for high performance at a competitive price. They are accurate, stable, and offer excellent directional response in both the near and far-field. They are available in two lengths.
Bluetooth Interfaces
R&D and production-grade Bluetooth interfaces connect Bluetooth devices to SoundCheck with full control over Bluetooth protocol settings including CODEC selection and transmitter power. This enables precise, repeatable testing under controlled conditions and makes it easy to compare characteristics like frequency response across different compression algorithms or sample rates.
The MDT-4000 Audio Measurement Turntable
The MDT-4000 audio measurement turntable seamlessly integrates with SoundCheck for rapid, streamlined testing. It is accurate, fast, and quiet, with many safety and usability features to facilitate setup and operation.
