However, this kind of speakers usually doesn't have a volume controller, which means a pre-amplifier is needed.Active monitor speakers are mostly placed on the desk and used for near field listening.

It has a high quality potentiometer for this purpose. It will convert an RCA input to a balanced, XLR, output. But it would probably be more cost effective, and space saving, to purchase RCA to XLR cables if that’s all you want to do. **Q: Does this preamp output +4dBu or -10dbV?** A: Hello. This is a fully passive preamp with no amplification function. **Q: Is the case (including front panel) made of metal?** A: Yes, all metal. It is a ver solid unit. **Q: Can i use this between an amp (Topping MX3) and powered speakers to protect the speakers amp?** A: No. It would make more sense to use the headphone output and find a splitter to connect it to your powered speakers. ## Frequently Bought Together - Nobsound Mini Fully-Balanced/Single-Ended Passive Preamp; Hi-Fi Pre-Amplifier; XLR/RCA Volume Controller for Active Monitor Speakers (Black) - Cable Matters 2-Pack Premium Short XLR to XLR Cables - 3ft, Male to Female Microphone Cable, Oxygen-Free Copper (OFC) Mic Cord, Black - VANDESAIL XLR Cables, 3ft 2 Pack Microphone Cable, XLR Male to Female Balanced Microphone Cord 3 pin, 3 Foot Short mic Cord Oxygen-Free Copper (OFC) Nylon Braided --- ## 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.ph/products/37158569-mini-fully-balanced-single-ended-passive-preamp-hi-fi-pre](https://www.desertcart.ph/products/37158569-mini-fully-balanced-single-ended-passive-preamp-hi-fi-pre) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-07-18*
