The IC is also a sound processor that includes all of the functions required to process the audio signal for TV \u0026amp; Mini Compo, such as Tone control, Volume, Mute, Balance, Loudness, 3 Stereo inputs selector, 1 Stereo output, and 1 Subwoofer out are all built into a single chip to provide Audio system having the highest audio performance and reliability. If a system wants subwoofer signal output, a traditional solution needs a lot of discrete components and OPAMPs to consist of a low pass filter; the PT2033, only needs 2 external capacitors. The PT2033 combines the low pass filter inside the audio processor and the user may determine low pass corner frequency by the capacitance. A broader supply range emphasizes support to every application.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eWide operation range (VDD from 4V to 10V)\u003c\/li\u003e\n\u003cli\u003eControlled by I²C interface\u003c\/li\u003e\n\u003cli\u003e3 Stereo Inputs with gain selection.\u003c\/li\u003e\n\u003cli\u003eScrew Terminals for Easy Inputs and Outputs connections\u003c\/li\u003e\n\u003cli\u003eHeader Connector for Power Supply Input\u003c\/li\u003e\n\u003cli\u003eInput gain range, from 0dB to +11.25dB, 3.75dB per step\u003c\/li\u003e\n\u003cli\u003e2 channels master volume: from 0 dB to -78.75dB, 1.25dB per step\u003c\/li\u003e\n\u003cli\u003eBuilt In channel mixer and lowpass filter for subwoofer output\u003c\/li\u003e\n\u003cli\u003eSubwoofer output volume: from 0dB to -37.5dB, 1.25dB per step\u003c\/li\u003e\n\u003cli\u003eTone control (Bass and Treble): from -14dB to +14dB, 2dB per step\u003c\/li\u003e\n\u003cli\u003eLow harmonic distortion (0.002%, Vo=200mVrms)\u003c\/li\u003e\n\u003cli\u003eLow noise and DC offset\u003c\/li\u003e\n\u003cli\u003eOn Board Power LED\u003c\/li\u003e\n\u003cli\u003e4 x 3MM Mounting Holes\u003c\/li\u003e\n\u003cli\u003ePCB Dimensions 65.41 x 43.18 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eConnections\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCN1: Pin 1 = Audio Input Left 1, Pin 2 = Audio Input Left 2, Pin 3 = Audio Input Left 3, Pin 4 = GND\u003c\/li\u003e\n\u003cli\u003eCN2: Pin 1 = Audio Input Right 1, Pin 2 = Audio Input Right 2, Pin 3 = Audio Input Right 3, Pin 4 = GND\u003c\/li\u003e\n\u003cli\u003eCN3: Pin 1 = Audio Output Left Channel, Pin 2 = GND\u003c\/li\u003e\n\u003cli\u003eCN4: Pin 1 = Audio Output Right Channel, Pin 2 = GND\u003c\/li\u003e\n\u003cli\u003eCN5: Pin 1 = Audio Output Subwoofer, Pin 2 = GND\u003c\/li\u003e\n\u003cli\u003eCN6: Pin 1 NC, Pin 2 = SCL-I2C, Pin 3 = SDA-I2C, Pin 4 = GND\u003c\/li\u003e\n\u003cli\u003eCN7: Pin 1,2 = VDD , Pin 3,4 = GND\u003c\/li\u003e\n\u003cli\u003eD1: Power LED\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"dotfry","offers":[{"title":"Default Title","offer_id":47197148283052,"sku":"A129","price":29.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/6436\/7532\/files\/A129.jpg?v=1789303908","url":"https:\/\/dotfry.com\/products\/2-1-channel-audio-processor-with-subwoofer-output","provider":"dotfry","version":"1.0","type":"link"}
