No electronics. No power. No distortion. Just a 2-way switch and a potentiometer.Huh? Why would you want such a thing? Well, if you've ever wanted to use one of our DACs with powered monitors, Sys puts the volume control right at hand. Same goes for using two sources with one of our headphone amps—use Sys to switch between a DAC and a phono preamp, for example. And, you don't have to use Sys with our gear at all. It's a simple, high-quality, passive preamp that works with pretty much any line-level source.Designed and Assembled in USA By “designed and assembled in USA" this is what we mean: the vast majority of the total production cost of SYS—chassis, boards, assembly, etc—goes to US companies manufacturing in the US. Our chassis are made minutes from our facility. Our PCBs are done just over the hill from us, or done in NorCal. You get the picture.2-Year Warranty SYS is covered by a limited warranty that covers parts and labor for two years. That’s 2x the warranty of most of the products in this price range. Review: Très bon produit Review: 車のオーディオに使用してます 純正や社外品のオーディオ（ヘッドユニット）を使用せずに、ストリーミングオーディオやネットフリックスの音声をアクティブクロスオーバーネットワーク、パワーアンプを経由し、スピーカーから出力するために、アッテネーター兼セレクターとして購入しました。 確かにいわゆるプリアンプ的な存在ではありますが、電源レスで1ミリも信号の増幅をしていないのにパッシブという名をつけたところでアンプを名乗っていいのか甚だ疑問ですが、 こまけーことを言うタイプの人はたぶん買わない商品なので言いません（言ってる）。 アメリカよりDHLで届いたので、為替や送料の影響はあるにせよ、価格に対してもう少し質感が欲しいところです。 ## Features - It's a 2-input passive preamp that adds no distortion, and gives you complete volume control. - Works with pretty much any line-level source. - It's just a 2-way switch and a volume knob. That's all. - Designed and assembled in the USA from high quality components. - For those times when you want to switch sources without unhooking one and rehooking up another. Hook them both up to SYS and have full control over which one you're listening to and at what volume. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BCMKH2ZT | | Amplifier Type | Passive | | Best Sellers Rank | #165,799 in Electronics ( See Top 100 in Electronics ) #532 in Home Audio Amplifiers | | Brand | Schiit | | Built-In Media | SYS | | Color | Black | | Compatible Devices | Monitors | | Connector Type | RCA | | Customer Reviews | 4.7 4.7 out of 5 stars (107) | | Enclosure Material | Metal | | Manufacturer | Schiit | | Mfr Part Number | SCH-13B-FA | | Model Name | SYS | | Output Channel Quantity | 2 | | Power Source | Passive | | Unit Count | 1 Count | ## Product Details - **Brand:** Schiit - **Colour:** Black - **Compatible devices:** Monitors - **Material:** Metal - **Model name:** SYS ## Images ![SYS Passive Preamp Volume Control and 2-Input Switch (Black) - Image 1](https://m.media-amazon.com/images/I/81HHvGN+ppL.jpg) ## Questions & Answers **Q: Does the loudness decrease evenly (log taper) or does it stay flat for most of the range and then abruptly go soft at the low end?** A: No abrupt volume change. **Q: will this up the line level from my cell phone to my home amps RCA input to play thru my stereo speakers?** A: Nope, it’s a complete straight pass through, zero power. I love mine, although I do wish the volume knob was a bit larger. **Q: I have the output in mill-volts range, and want it to upped to line level which can be fed to the amp. Can this act as phono amp?** A: Of course not **Q: will the switch degrade the sonic? I'm using 10AWG speaker wire, and etc. will this be the weakest section of my audiophile system?** A: I have huge gear hanging off of this (sunfire) and cannot tell any difference between channels when switching. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by S***E on 17 January 2026* Très bon produit ### ⭐⭐⭐⭐ Review *by 満***様 on 22 September 2024* 車のオーディオに使用してます 純正や社外品のオーディオ（ヘッドユニット）を使用せずに、ストリーミングオーディオやネットフリックスの音声をアクティブクロスオーバーネットワーク、パワーアンプを経由し、スピーカーから出力するために、アッテネーター兼セレクターとして購入しました。 確かにいわゆるプリアンプ的な存在ではありますが、電源レスで1ミリも信号の増幅をしていないのにパッシブという名をつけたところでアンプを名乗っていいのか甚だ疑問ですが、 こまけーことを言うタイプの人はたぶん買わない商品なので言いません（言ってる）。 アメリカよりDHLで届いたので、為替や送料の影響はあるにせよ、価格に対してもう少し質感が欲しいところです。 ### ⭐⭐⭐⭐⭐ Review *by J***G on 18 November 2025* I use this to switch between bookshelf speakers powered by a Marantz 1060 integrated receiver, and floor speakers powered by a separate power amp, with the Marantz as the preamp. This makes it impossible to run both speakers at the same time, which would damage my equipment. It's a little pricey comparatively, but not really, because it's very well made and will obviously last as long as my other high quality equipment. It looks good and feels solid, and there is no noise or interference at all...like it should be. ## Frequently Bought Together - Schiit SYS Passive Preamp Volume Control and 2-Input Switch (Black) - Monoprice 1.5ft Premium 2 RCA Plug/2 RCA Plug M/M 22AWG Cable - Black - CESS-163-4i Low Noise 12 Gauge Premium RCA Audio Line Patch Cable (4 Inches) --- ## 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.in/products/528016061-sys-passive-preamp-volume-control-and-2-input-switch-black](https://www.desertcart.in/products/528016061-sys-passive-preamp-volume-control-and-2-input-switch-black) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-05-20*
