Easy Connection and Quick Integration
APM2 comes with a necessary demonstration firmware, so you can use it in your audio systems directly with no need of programming. A 2 x in, 3 x out Interface extension board – APM3 is provided for easy audio connection, which offers multiple kinds of interfaces, including RCA jack, 3.5mm AUX IN jack and PH-4Pos line input connector. After connection with APM3, APM2 can be easily integrated into any projects, such as Kiosk, Speaker Equalization, Active Crossovers, Digital Car Audio System, Home Theater, Karaoke, Musical Instruments and so on. APM2 and APM3 are both in 2’’ x 2’’ compact size, making them simple to be installed in any cabinet without occupation of too much space to leave enough headroom for other components.
High Performance ADAU1701
The on board fully programmable 28-/56-bit audio DSP ADAU1701 from Analog device is competent in various signal processing applications. This process can compensate for real-world limitations of speakers, amplifiers, and listening environments, providing dramatic improvements in perceived audio quality.
Four potentiometers are provided on APM2 for real time hardware control of the whole audio system for volume, gain and cut-off frequency setting.
Supporting SigmaStudio Program and Remote Control
Different applications have unlike requirements on audio as the speakers, the environment and the preference are different. To give customers better control of audio systems, Sure Electronics has released In-circuit programmers (ICP series), with connection of which, you can program DSP with SigmaStudio or remote control the system with APP or PC UI.
We have developed an APP – Miumax for remote control, with which, you can adjust volume, gain, frequency and EQ setting. PC UI is also available for different applications as digital crossover, bass enhancement, subwoofer, and so on.
Sure Electronics has provided open-sourced files for customers to start the project quickly. Please refer to the
