I use it to power two passive Dolby height speakers on my 9.2 Dolby Atmos Denon AV Reciever. **Q: Does this need a pre-amp, or can it be connected to a DAC?** A: I've got this connected to a Project Pre Box S2 DAC which is connected to my PCs. This works well for me. **Q: which model would be best for AE 100 series, max 75w, min impedance 6 ohms plugged into an applemac mini** A: TPA3116 - only 19V power supply, so less than 50w into 6 ohm. - and no tone control. TB10A probably better, esp if you need tone control. The 24v power supply gives more ability to turn up the bass. Allan Hendry. MonoPulse. **Q: Anyone have problems with background noise from the v1.0g. i play a lot of classical as well as rock. i was hoping for complete silence when its on.** A: No problem with mine regarding noise. I would check your cables, try a different source-maybe your unit has a fault? ## Frequently Bought Together - Fosi Audio V1.0G 2 Channel Class D Mini Stereo Amplifier for Home Speakers TPA3116 50W x 2 with Power Supply - FosPower Banana Plugs 2 Pairs / 4 pcs, Closed Screw 24K Gold Plated Banana Speaker Plug Connectors for Speaker Wire, Wall Plate, Home Theater, Audio/Video Receiver, Amplifiers and Sound Systems - Amazon Basics 16-Gauge Speaker Wire Cable, 50 feet, Transparent --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/66282134-v1-0g-2-channel-amplifier-stereo-audio-amp-mini-hi](https://www.desertcart.jp/products/66282134-v1-0g-2-channel-amplifier-stereo-audio-amp-mini-hi) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-05*
