It accepts Bluetooth audio and wired sources, offers True Wireless Stereo (TWS) pairing to create left\/right channels from two modules, and tolerates a wide voltage range for battery and mains-adapter setups. The board is intended for hobbyists and installers who want high-efficiency Class D amplification with modern connectivity in a small footprint.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the ZK-1001B connect to my devices?\u003c\/h3\u003e\n\u003cp\u003eThe board supports Bluetooth wireless streaming plus several wired inputs so you can use it with phones, laptops, MP3 players, or a USB thumb drive. Inputs are selectable and the USB socket can accept a flash drive or act as a USB sound card depending on how you configure the source.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eBluetooth wireless streaming for phones and tablets\u003c\/li\u003e\n  \u003cli\u003e3.5mm AUX line-in for older devices or mixers\u003c\/li\u003e\n  \u003cli\u003eUSB input supporting flash drives and USB audio modes\u003c\/li\u003e\n  \u003cli\u003eWiring terminals for speaker outputs and power (DC7–24V)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat audio performance and power can I expect?\u003c\/h3\u003e\n\u003cp\u003ePowered by the TPA3116D2 Class D amplifier chip, this board offers efficient amplification and clean output suited to bookshelf or compact PA speakers. The specification lists a 100W peak output — real continuous output depends on supply voltage, speaker impedance, and cooling — but the board is built to deliver strong, low-distortion sound for its size.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTPA3116D2-based Class D amplification for efficiency\u003c\/li\u003e\n  \u003cli\u003ePeak output rating of 100W (dependent on voltage and impedance)\u003c\/li\u003e\n  \u003cli\u003eWorks with typical 4Ω–8Ω speaker drivers\u003c\/li\u003e\n  \u003cli\u003eRequires adequate cooling for sustained high-power use\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I use the TWS feature and multi-board setups?\u003c\/h3\u003e\n\u003cp\u003eTWS mode pairs two identical ZK-1001B boards so one plays the left channel and the other plays the right, creating a stereo field from two mono amplifiers. Pairing is handled by the multifunction control — a short press initiates sync — making it simple to set up without extra wiring for stereo separation.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eQuick-press multifunction knob to initiate TWS sync\u003c\/li\u003e\n  \u003cli\u003eOnce paired, boards act as left and right channels wirelessly\u003c\/li\u003e\n  \u003cli\u003eUse two identical units for best channel balance\u003c\/li\u003e\n  \u003cli\u003eMaintain stable Bluetooth conditions during pairing\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat protections and installation details should I know?\u003c\/h3\u003e\n\u003cp\u003eThe ZK-1001B includes multiple protective circuits to help prevent damage during improper use, and it supports a broad input voltage to suit portable and fixed systems. Proper wiring, a correct voltage supply, and ventilation ensure reliable operation and avoid triggering protection modes.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eOver-voltage and under-voltage protection to guard supply faults\u003c\/li\u003e\n  \u003cli\u003eOver-temperature and short-circuit protections for safety\u003c\/li\u003e\n  \u003cli\u003eWide DC7–24V input for battery packs or external adapters\u003c\/li\u003e\n  \u003cli\u003eFollow polarity and grounding best practices when wiring\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: The Wuzhi Audio ZK-1001B is aimed at audio tinkerers, small-scale OEMs, and hobbyists building compact powered speakers, portable boomboxes, or desktop stereo pairs. Choose this board if you want efficient Class D power, Bluetooth with TWS stereo capability, multiple input methods, and built-in safety features — provided you can supply appropriate voltage, ensure cooling, and wire speakers correctly.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What voltage does the amp board require?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It accepts DC7–24V; use a stable supply sized for your speaker load and desired output.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can two boards create stereo sound?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes—use the TWS function to pair two ZK-1001B boards for left and right channels.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Wuzhi Audio","offers":[{"title":"Default Title","offer_id":48413298753693,"sku":"B0FF24K2BT","price":37.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/9596\/1757\/files\/wuzhi-audio-zk-1001b-front-view.jpg?v=1781259960","url":"https:\/\/nexoltic.com\/products\/wuzhi-audio-zk-1001b-mono-bluetooth-amplifier-board-100w","provider":"Nexoltic","version":"1.0","type":"link"}
