Product Overview

EX201 DSP Digital 2.1-Channel Amplifier Board
EX201 DSP digital 2.1-channel amplifier board integrates a high-performance 32-bit DSP processor, with ADC and DAC supporting 48kHz input and output sampling rates for high-fidelity audio reproduction.
Audio Decoding Algorithms: Supports MP2, MP3, MP4, and WAV audio decoding; encoding support includes MP2/MP3 and IMA-ADPCM to accommodate various audio source formats.
Music Effects Processing: Noise reduction, 3D stereo surround, wide soundstage expansion, high-frequency excitation, PEQ equalizer, DRC dynamic limiter, and phase delay adjustment; supports PC-based online tuning and OTA firmware upgrades for optimal acoustic matching.
Microphone Effects Processing: Noise reduction, reverberation, PEQ equalizer, voice changing, frequency shifting, and anti-howling processing to enhance vocal clarity and singing experience.
Input Support: Dual microphone inputs, onboard Bluetooth audio decoding, USB lossless soundcard input, 3.5mm AUX analog input, and USB drive playback for versatile application scenarios.
Output Power: 2.1-channel output configuration; left/right channels drive 4Ω loads at 50W × 2; subwoofer channel drives 2Ω loads at 100W, suitable for desktop audio systems and compact KTV setups.
Dual-Mode Bluetooth V5.3, backward compatible with V4.2 and V2.1+EDR, supporting Bluetooth Piconet and Scatternet networking; maximum transmit power 10dBm, with support for A2DP/AVRCP/HFP/OPP/HID/SPP/PBAP/GATT/SM protocols.
Power Requirements: Wide voltage input range 6V–24V DC; standard power output requires 24V supply with 3–10A current capacity to ensure stable high-power dynamic performance.
Default Bluetooth Name: EIFFELTON MX201
