AmpConnect 621 Demo Video
In this short video, sales engineer Les Quindipan gives a brief overview and demonstration of the new AmpConnect 621 multichannel, high-resolution audio interface.
New AmpConnect 621 Multichannel, Multifunction Audio Interface
AmpConnect 621
The new AmpConnect 621 is Listen’s next generation multichannel, multifunction, high resolution audio test interface. It is ideal for any application where more than 2 channels are needed, for example, automotive audio, voice-activated device measurements, sound power measurements and measuring devices with multiple speakers such as soundbars and smartphones. With a sample rate of up to 192kHz, it is also a great choice for measuring high resolution devices such as headphones and hearables. Additionally, it includes all the functionality required for audio testing in just one unit, including an amplifier, microphone power supply, line outputs and digital I/O.
AmpConnect 621 features 6 inputs, 2 line outputs and one amplifier output. All inputs offer microphone power (SCM, IEPE and pre-polarized), to accommodate many types of couplers, accelerometers and reference microphones – even the new Brüel and Kjær 5128 high resolution head and torso simulator. Full TEDS support for microphones and accelerometers simplifies setup and calibration by importing the data at the click of a button. The 2 line level outputs plus a separate 50W amplifier route the output signal to any sources, powered or needing amplification, (e.g. artificial mouth, speakers, headphones, automotive head units). Impedance measurements using the amplifier output, along with output voltage monitoring, are performed entirely internally and do not require using any of the 6 external input channels, leaving them open for other measurements. This, along with digital I/O, simplifies operation as signals are all routed internally with no additional cabling required. The device connects to the computer with a single USB cable; the only additional cables required are those connecting your microphones and DUTs. This all-in-one approach offers excellent ground loop immunity in comparison to discrete components.
The interface has no control knobs on the front; control is entirely through the SoundCheck software interface. This minimizes errors by making it impossible for settings to be accidentally changed. For example, in a production environment, the only way the operator can adjust the settings is by modifying the test sequence, and access to this can be restricted via operator access rights. This helps OEMs ensure test integrity when requiring contract manufacturers or offshore manufacturing facilities to run their test sequences. This is also advantageous for protecting against accidental changes in a laboratory, particularly when multiple people are accessing the same piece of equipment. The front panel features visual indicators for power, input and output level, amplifier channel and level so that overloads, etc. can be clearly identified.
Test deployment is fast with full plug and play functionality. Channel configuration is fully automatic when the AmpConnect 621 is connected to the SoundCheck computer – the user just needs to adjust driver selection and sampling rate if different from the default values. Calibration data is read from TEDS microphones in SoundCheck’s calibration editor, or easily imported from a calibration file. When setting up multiple systems, the AmpConnect only needs to be configured once, and the setup can be duplicated to other test stations; there is no need to re-configure AmpConnect 621 each time.
AmpConnect 621 offers the option to use WASAPI-exclusive mode with Windows 10 audio devices in addition to the more commonly used ASIO drivers. This advanced communication protocol allows SoundCheck to bypass the Windows audio mixer, sending audio streams directly to the device. This results in lower latency and ensures that there is no sample rate conversion behind the scenes. It also enables SoundCheck to put an exclusive lock on the audio interface so that a measurement cannot be disrupted by system sounds which is valuable in highly automated settings. Multiple WASAPI devices can be used simultaneously, and WASAPI and ASIO devices can be combined to increase channel availability.
Like Listen’s other hardware products, AmpConnect 621 is built to last in production environments. The 17” wide x 2-Units (3.5”) high x 11.5” deep rack-mountable unit is rugged with a new fingerprint-resistant matte finish.

SoundCheck® 19 offers new features for multi-channel and room acoustics, as well as many usability upgrades including:
- Multichannel RTA: The single-channel RTA is replaced with a new multi-channel version, which enables viewing of multiple signal paths simultaneously for a convenient view of many measurements across a wide range of applications. Spectrum settings are configured independently for each channel for complete measurement flexibility.
- Room Acoustics RT60 (optional module): This module offers extremely fast and accurate measurement of the reverberation time and clarity of any room or space with calibrated signal paths.
- WASAPI-Exclusive Mode: SoundCheck can now operate in WASAPI-exclusive mode. This delivers lower latency, ensures that sample rate conversion from the built-in Windows audio engine will not occur, and enables SoundCheck to ‘lock’ the audio interface to avoid measurement disruption by system sounds.
- AmpConnect 621 Control: SoundCheck 19 supports AmpConnect 621, Listen’s new high resolution multichannel audio interface. Set-up and configuration is extremely simple and fast with full plug-and-play functionality and TEDS support for automatic identification, configuration and calibration of microphones and accelerometers.
- Diagnostic Window: Warning dialog windows can now be suppressed when running a sequence, instead logging the errors, warnings, and information in a separate diagnostic window. This avoids sequence interruption by dialog windows in unattended or highly automated situations.
- USB Controller Knob Compatibility: SoundCheck communicates with the Drok USB Controller Knob to simulate the feel of a manual analog signal generator. Used in conjunction with other virtual instruments such as the RTA, spectrum analyzer and distortion meter, this offers a rapid way to identify defects by observing the response while manually fine-tuning the signal generator.

SoundCheck® 19 Released: New Features for Multichannel Measurements
SoundCheck® 19, the new release of Listen, Inc.’s flagship audio test and measurement system, offers additional functionality for multichannel measurements, including a new Multi-channel RTA, WASAPI-exclusive mode, and AmpConnect 621 control. Additionally, the inclusion of room acoustics measurements offers increased capability for those looking to evaluate devices in real-world situations. Many of these features also add value on the production line, minimizing setup time, reducing the chance of user-error, and ensuring smoother operation in automated situations.
In this release, the original ANSI S1.11-2004 Class 0 standard compliant, single-channel RTA has been enhanced to show multiple channels simultaneously. Settings for these can be configured independently, e.g. adding different weighting curves, and the power-averaged response displayed. This presents a convenient view of many measurements across a wide range of applications including overlaying left and right earphone responses to check for fit and seal, microphone array captures (e.g. in-vehicle cabin measurements), real time adjustment of active noise cancellation filter, and more. For maximum flexibility, spectrum settings are set independently for each channel, and all multi-channel RTA functionality can also be used within a test sequence for automation.
The optional RT60 Room Acoustics module enables measurement of the reverberation time and clarity of any room or space with fully calibrated signal paths. This is useful for quantifying how speakers will interact with the acoustics of a particular type of room. It can also help identify problems with room acoustics so that the floor, ceiling and walls can be treated accordingly. SoundCheck uses a continuous sine sweep with the Log TSR algorithm to obtain the impulse response. The reverberation decay curve is calculated from the backwards integrated impulse response. This method, conforming to ISO 3382-1:2009, offers extremely fast measurements, requires just one measurement at each location, and minimizes the effect of noise and distortion on the measurement.
Another enhancement is the option to use WASAPI-exclusive mode with Windows 10 audio devices. This advanced interface offers superior communication with audio devices, allowing SoundCheck to bypass the Windows audio engine, and send audio streams directly to the device. This delivers lower latency and ensures that sample rate conversion from the built-in Windows audio engine will not occur. It also enables SoundCheck to put an exclusive lock on the audio interface so that a measurement cannot be disrupted by system sounds. The ability to use multiple WASAPI devices simultaneously offers significant advantages for multichannel applications, particularly where the channel count requires multiple audio interfaces. WASAPI and ASIO devices can be combined to increase channel availability.
SoundCheck 19 supports AmpConnect 621, Listen’s new high resolution (up to 192kHz) multichannel audio interface. AmpConnect 621 has no front panel controls; it is exclusively configured via the SoundCheck 19 software. Set-up and configuration is extremely simple and fast with full plug-and-play functionality and TEDS support for automatic identification, configuration and calibration of microphones and accelerometers. The absence of front panel knobs also provides an added level of test integrity by ensuring that settings cannot be inadvertently adjusted outside of your test configuration. SoundCheck 19 with AmpConnect 621 is a simple and cost-effective solution for automotive measurements with a 6-microphone array, sound power measurements, or for measuring devices with multiple speakers such as smartphones or sound bars.
Also new is a diagnostic window which enables suppression of warning dialog windows when running a sequence, logging any errors, warnings, and information in a separate file. This is useful when Soundcheck is run in unattended or in highly automated situations (for example, on a production line) where dialog windows would interrupt the execution of a sequence. It also facilitates troubleshooting as the log is easily shared via email. SoundCheck also now allows the Drok USB Controller Knob to be used to adjust the SoundCheck Signal Generator, simulating the feel and control of operation of a traditional manual analog signal generator. Used with other virtual instruments such as the RTA, spectrum analyzer and distortion meter, this offers a rapid way to identify defects by observing the response while manually fine-tuning the signal generator.
