Mini input jack may be bad. How do I return for replacement? purchased 9/2/22** A: Try a new supply for cable to usb ie another high power charger. **Q: Can this amplify a video signal to allow splitting on multiple viewing screens ?** A: No. It is for audio only (and in my opinion, doesn't even do that well). You need a device that is specifically for video, like this: https://www.amazon.com/MT-VIKI-Splitter-Composite-Distribution-Amplifier/dp/B0882RHYTW/ This will take a composite video input, amplify it, and provide multiple outputs. It also does the same for the associated audio inputs. **Q: What are the exact dimensions of the power connector? The connector has 2 dimensions, the outer diameter and the inner pin diameter (5.5 mm x?)** A: I don't know. My Mini Stereo Line Level Amp stopped working the second week I owned it. I recommend buying something else. **Q: Will it give a full 2 volt line out RCA signal** A: So long as the input level is sufficient to create a 2V output signal, the answer is yes. If the input signal is not of sufficient amplitude it will/can not. ## Frequently Bought Together - Douk Audio L1 Mini Stereo Line Level Booster Amplifier Audio Preamp with 20dB Gain and Volume Control - Monoprice 1.5ft Premium 2 RCA Plug/2 RCA Plug M/M 22AWG Cable - Black - AtNeDcVh Mini Small Stereo Audio preamplifier, Headphone Amplifier, Gain 20dB Phono Turntable Phonograph preamp, Dual op amp NE5532 with RCA 3.5mm Input to RCA 3.5mm Output --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/243819127-douk-audio-l1-mini-stereo-line-level-booster-amplifier-audio](https://www.desertcart.tn/products/243819127-douk-audio-l1-mini-stereo-line-level-booster-amplifier-audio) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-11*
