AmpConnect ISC

In addition to the audio interface, AmpConnect ISC also provides microphone power, drives speakers and headphones, and includes impedance measurement circuits. Further features include automated control of signal routing, input gain and instrument configuration. Especially useful is complete integration peak level detection and automatic input gain control. When used with SoundCheck the input gain is automatically optimised for every acquisition.

AmpConnect’s simple setup and compact package make it ideal for production line applications. The digital I/O ports can be used for communicating with relay boards, lighted pass/fail indicators, footswitches and other devices. The front panel can be disabled, locked out, and the instrument controlled exclusively via SoundCheck to ensure that the hardware is always configured correctly. Furthermore, automated output signal routing and dual microphone inputs allows AmpConnect to be configured to alternate between two test stations, maximising throughput.

It also offers excellent functionality for the R&D lab. The two independently configurable signal routing options enable virtually any test to be realised – for example, they can be used for measuring impedance using the internal reference loads (and Listen’s patent-pending high accuracy single channel impedance measurement method), connecting the output of the power amp back to the soundcard for calibration, or sending reference or DUT signals to the outputs.

Features include:

• All components for testing loudspeakers, headphones and microphones in a single unit with just one USB connection to the computer
• True plug and play operation and fully integrated with SoundCheck
• Automated control via SoundCheck or manual control via the front panel interface.
• Rugged and rack-mountable for demanding production environments
• Excellent ground loop immunity compared to discrete components
• Clear indications (software and LED) that microphone, DUT, and power amplifier levels are all operating within the maximum dynamic range
• Unique patent-pending high accuracy single channel impedance measurement
• CE Marked (please request CE Marked version at the time of order)
