If you already have an amplifier or active speakers, a DAC is enough.<\/p>\n<h2>Compatibility and pitfalls to avoid<\/h2>\n<ul>\n<li><strong>External power supply required<\/strong>, not included: a 12 to 24 V DC adapter rated for 3 A, with a 5.5 \u00d7 2.5 mm plug.<\/li>\n<li><strong>Never power the Raspberry Pi through its own port<\/strong> when the DigiAMP+ is connected: the HAT takes care of it.<\/li>\n<li><strong>Pi 4 and Pi 5<\/strong> : the DigiAMP+ was designed around the Pi 3. On a Raspberry Pi 4 or a Raspberry Pi 5, connect power-hungry USB devices to a separately powered USB hub to avoid the undervoltage warning.<\/li>\n<li><strong>Only one I2S audio HAT<\/strong> at a time: it cannot be stacked with another DAC.<\/li>\n<li><strong>Passive speakers only<\/strong> : do not connect active speakers or headphones to the terminal blocks.<\/li>\n<li><strong>Black IQaudIO or green Raspberry Pi board<\/strong> : they are electrically equivalent, only the EEPROM memory differs.<\/li>\n<\/ul>\n<h2>What's in the box<\/h2>\n<p>The DigiAMP+ board and the mounting hardware (standoffs, screws and connectors), according to the official documentation. Power supply and speakers not included.<\/p>\n<h2>Recommended accessories<\/h2>\n<ul>\n<li><a href=\"https:\/\/monraspberry.com\/en\/product\/raspberry-pi-3-model-b\/\">The Raspberry Pi 3 Model B+<\/a> : the platform the DigiAMP+ was designed for, with no USB constraints.<\/li>\n<li>A SanDisk Ultra micro SD card for the system and your playback software.<\/li>\n<li><a href=\"https:\/\/monraspberry.com\/en\/product\/raspberry-pi-4-model-b-4-gb\/\">The Raspberry Pi 4 Model B 4 GB<\/a> if you also want to decode video or host your music library.<\/li>\n<\/ul>\n<h2>Uses and projects<\/h2>\n<p>Network player for bookshelf speakers, in-store sound system, internet radio, multiroom system: the DigiAMP+ turns a Raspberry Pi into a connected amp. For the software side, read our guide <a href=\"https:\/\/monraspberry.com\/en\/multimedia-streaming-system-on-raspberry-pi\/\">multimedia streaming system on Raspberry Pi<\/a>.<\/p>\n<h2>Frequently asked questions<\/h2>\n<h3>Which power supply should I choose for the DigiAMP+?<\/h3>\n<p>A 12 to 24 V DC adapter able to deliver 3 A, with a 5.5 \u00d7 2.5 mm plug. It powers both the amplifier and the Raspberry Pi.<\/p>\n<h3>Does the DigiAMP+ power the Raspberry Pi?<\/h3>\n<p>Yes, it supplies 5.1 V at 2.5 A to the Pi through the GPIO header. Do not connect a power supply to the Pi at the same time.<\/p>\n<h3>Is it compatible with the Raspberry Pi 5?<\/h3>\n<p>It fits any Pi with a 40-pin GPIO. On the Pi 4 and Pi 5, power your power-hungry USB devices through a powered hub.<\/p>\n<h3>Why is there no sound at startup?<\/h3>\n<p>The amplifier starts muted: the software re-enables it via GPIO 22.<\/p>\n<h3>Are IQaudio and Raspberry Pi the same product?<\/h3>\n<p>Yes. Raspberry Pi took over the IQaudio range; the black IQaudIO boards and the green Raspberry Pi boards are electrically equivalent.<\/p>\n<h3>Can I connect headphones?<\/h3>\n<p>No, the DigiAMP+ has no headphone output. For headphones, choose the DAC+ or the DAC Pro.<\/p>\n<p><strong>Order your DigiAMP+ amplifier on monraspberry.com<\/strong> : official, tested product, stock based in France, shipping within 24\/48 h after receipt of payment, free pickup point delivery on orders from \u20ac200, returns possible within 14 days with return authorization, and payment by Visa, Mastercard, PayPal, Apple Pay or Google Pay.<\/p>","protected":false},"excerpt":{"rendered":"<ul>\n<li>Turn your Raspberry Pi into a hi-fi amplifier for two passive speakers.<\/li>\n<li>TAS5756M, 24-bit \/ 192 kHz, up to 35 W per channel, 12 to 24 V power supply.<\/li>\n<li>HAT for any Raspberry Pi with a 40-pin GPIO, which it also powers.<\/li>\n<\/ul>","protected":false},"featured_media":27566,"template":"","meta":[],"product_brand":[393],"product_cat":[29,24,19],"product_tag":[],"class_list":["post-27523","product","type-product","status-publish","has-post-thumbnail","product_brand-raspberry-pi","product_cat-hats-raspberry-pi-3-pi-2","product_cat-hats-raspberry-pi-4","product_cat-hats-raspberry-pi-5","first","onbackorder","taxable","shipping-taxable","purchasable","product-type-simple","add-to-wishlist-after_add_to_cart"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/monraspberry.com\/en\/wp-json\/wp\/v2\/product\/27523","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/monraspberry.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/monraspberry.com\/en\/wp-json\/wp\/v2\/types\/product"}],"version-history":[{"count":1,"href":"https:\/\/monraspberry.com\/en\/wp-json\/wp\/v2\/product\/27523\/revisions"}],"predecessor-version":[{"id":33635,"href":"https:\/\/monraspberry.com\/en\/wp-json\/wp\/v2\/product\/27523\/revisions\/33635"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/monraspberry.com\/en\/wp-json\/wp\/v2\/media\/27566"}],"wp:attachment":[{"href":"https:\/\/monraspberry.com\/en\/wp-json\/wp\/v2\/media?parent=27523"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/monraspberry.com\/en\/wp-json\/wp\/v2\/product_brand?post=27523"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/monraspberry.com\/en\/wp-json\/wp\/v2\/product_cat?post=27523"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/monraspberry.com\/en\/wp-json\/wp\/v2\/product_tag?post=27523"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
