This slim little board has a class D amplifier onboard that can drive 2 channels of 4-8 ohm impedance speakers at 20W each. Power it with 5-12VDC using the onboard DC power jack and plug stereo line level into the 3.5mm stereo headphone jack and jam out with ease. Since it's class D, its completely cool-running, no heat sinks are required and it's extremely efficient - up to 93% efficiency makes it great for portable or battery powered rigs.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003eWe like the MAX9744 amplifier at the heart of this board because its very easy to use, but it also has \u003cem\u003eboth analog and digital \u003c\/em\u003evolume control capability.

We also include 3 x 2pin and 1 x 3pin terminal blocks, a 470uF power filter capacitor and 1KΩ trim pot. To use this board, a little soldering is required to attach the terminal blocks and other components, but its fairly easy and expect it should take less than 15 minutes. \u003ca href=\"http:\/\/learn.adafruit.com\/adafruit-20w-stereo-audio-amplifier-class-d-max9744\" target=\"_blank\"\u003eCheck out our detailed tutorial for assembly instructions and overall usage\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003eNote: The terminal blocks included with your product may be blue or black.\u003c\/p\u003e","published_at":"2020-04-27T20:32:44-04:00","created_at":"2019-11-05T15:36:39-05:00","vendor":"Adafruit","type":"Adafruit","tags":[],"price":1990,"price_min":1990,"price_max":1990,"available":true,"price_varies":false,"compare_at_price":1995,"compare_at_price_min":1995,"compare_at_price_max":1995,"compare_at_price_varies":false,"variants":[{"id":31088792535158,"title":"Default Title","option1":"Default Title","option2":null,"option3":null,"sku":"K474","requires_shipping":true,"taxable":true,"featured_image":null,"available":true,"name":"Adafruit Stereo 20W Class D Audio Amplifier - MAX9744","public_title":null,"options":["Default Title"],"price":1990,"weight":0,"compare_at_price":1995,"inventory_quantity":30,"inventory_management":"shopify","inventory_policy":"continue","barcode":"","requires_selling_plan":false,"selling_plan_allocations":[]}],"images":["\/\/cdn.shopify.com\/s\/files\/1\/1749\/9663\/products\/1752-00.jpg?v=1572986199"],"featured_image":"\/\/cdn.shopify.com\/s\/files\/1\/1749\/9663\/products\/1752-00.jpg?v=1572986199","options":["Title"],"media":[{"alt":null,"id":5545436741750,"position":1,"preview_image":{"aspect_ratio":1.332,"height":728,"width":970,"src":"https:\/\/cdn.shopify.com\/s\/files\/1\/1749\/9663\/products\/1752-00.jpg?v=1572986199"},"aspect_ratio":1.332,"height":728,"media_type":"image","src":"https:\/\/cdn.shopify.com\/s\/files\/1\/1749\/9663\/products\/1752-00.jpg?v=1572986199","width":970}],"requires_selling_plan":false,"selling_plan_groups":[],"content":"\u003cp\u003ePump up the volume with this 20W stereo amplifier!
