Tempo Semiconductor TSCS42xx Audio HAT Board for Raspberry Pi Tempo Semiconductor, Inc. Applications The TSCS42xx Audio HAT Board enables any Raspberry Pi single-board computer to be transformed into a fully customizable complete audio solution for a wide variety of applications. Here are some of just a few of the possible use-cases for the TSCS42xx Audio Codec HAT when combined with your Raspberry Pi computer: Wired or Wireless multi-room streaming audio player / Smart Speaker / Voice Activated Assitant Mini Soundbar for placement above or below computer monitors Arcade table project with high quality, immersive audio Internet radio player with high quality stereo audio Gaming Headphone Amplifier Features The FIRST and ONLY Audio Codec HAT board for Raspberry Pi with an integrated DSP that is easily adjust- able using the TSCS42xx ALSA GUI and flash savable Full driver support in Raspbian* / NOOBS* / Linux Compatible with VLC / OSMC / RuneAudio / Volumio / Moode / PiCorePlayer / PiMusicBox / OpenELEC / etc. Standard terminal screw connects offer a standard method of connecting speakers Stereo analog line level input via 3.5mm jack (J11 Aux) Integrated Pop & Click-Free Capless, Ground-Center Referenced HP Driver via 3.5mm jack (J10 Headset) High-quality digital audio capture, processing and playback supporting up to 96kHz / 32-bit Linear PCM native input via digital audio inputs or via 32-bit stereo ADCs and 32-bit stereo DACs Compatible with Raspberry Pi 2B, 3B and new 3B+ Raspberry Pi board & TSCS42xx Audio HAT board powered via single Micro USB port (on HAT board) Hardware and software volume control from your Raspberry Pi or using joystick on HAT board Plug-and-play compatibility for ease of use Fully HAT CompliantTechnical Details Tempo Semiconductor TSCS42xx - Low-Power Audio Codec - 96kHz / 32-bit with integrated 24-bit signal processing engine Speaker Amplifier: Maximum power output of 2 x 3W* (RMS) into 4 Ohms at 10% THD+N, 2 x 1.5W* (RMS) into 8 Ohms at 10% THD+N (*with an appropriate power supply) Fully integrated hardware volume mixing via ALSAMIX or any ALSA compatible application The additional Hardware-based DSP Audio Processing features inside the TSCS42xx Codec DSP engine can be controlled via the I2C interface from the Broadcom SOC using the Tempo Semiconductor supplied, open- source ALSA compatible application GUI (or via command line controls): Two independent banks of stereo 6-band Parametric EQs or configurable biquad filters (such as High-Pass, Low-Pass, Band-Pass, All-Pass, etc) Wideband, Stereo DRC (Dynamic Range Compressor) Pro-Style, Stereo, 3-band Compressor / Limiter / Expander with independent Time & Frequency Domain adjustments Configurable Psychoacoustic Bass Enhancement Configurable High-Frequency Content Restoration Enhancement 3D Stereo Enhancement for surround encoded 2 channel content Integrated EEPROM for automatic Raspberry Pi device-tree driver configuration Total harmonic distortion (THD+N) of 0.05% at 1W, 1kHz, into 4 Ohms. HP Output signal-to-noise ratio (SNR) of 124 dB A-Wtd (using a digital silence output) / 102dB DNR End-to-end, 28-bit digital audio path with 384kHz upsampling prior to signal processing Note: *User is required to add the TSC42xx driver module to the rootfs that comes with both the Raspbian and NOOBS SD Card images. Detailed directions can be found on the above link. This board powers both the HAT board as well as the Raspberry Pi from a single power supply with a Micro USB cable. A universal AC/DC adapter with +5VDC output and 3A output current capability (or higher) with a USB Micro connector (like the standard Raspberry Pi 3 +5V, 2.5A Power Supply available from Mouser - but with a higher current capability) is required for proper opera- tion.
