Yes. It is a finished product. You only need to connect signal input and power input. **Q: The clock is very annoying! Any way to disable it, so it only acts as a spectrum display? Thanks** A: Disconnect from headphone jack when not in use. **Q: when plugged in to a audio source, Ii have 2 or 3 bars flickering like there picking up some interference. any solutions?** A: Got something similar happening with many bands even when there is minimal audio input. The problem appears to be a poor connection between the 1/8" plug and the socket on the analyser. What I have done is remove the plug, clean it, re-insert it and check. If that doesn't immediately solve the issue, I twist the plug in the socket until I get it to a position that zero input registers nothing on the analyser. **Q: What are the unit's dimensions?** A: 7" x 2" x 1" ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent device!👌🏼 *by on Reviewed in India 7 August 2026* Works perfectly fine and as described. If you're looking for a vintage vacuum tube based crystal clear spectrum analyzer for music frequency details, go for it. Five stars for its operational accuracy 💯, charming music enhancement and controlled menu options. ### ⭐⭐⭐⭐⭐ Amazing value, but setup required *by on Reviewed in the United States 24 July 2026* This little product has a LOT of features, settings, and customizable user options. That said, they are not the most intuitive, especially given the several-dozen-page instruction booklet’s countless typos. But once you learn to interpret them, they’re easy enough to follow.Do not expect a plug-and-play product; there’s a bit of assembly and setup you’ll have to do. But all-in-all, it’s maybe 15-20 minutes altogether.Once it’s working how you want, it’s fantastic! Especially for the money when compared with those multi-colored LED ones that also function as a vinyl stand. I think this product is far superior. ### ⭐⭐⭐⭐ デスクを彩る最高の視覚演出！ただし、ガチの音楽制作現場では注意が必要。 *by on Reviewed in Japan 31 March 2026* 【購入の目的と第一印象】デスク周りの視覚的な演出として購入しました。セットアップは非常にシンプルで、ケーブルを接続するだけですぐに音に反応して動いてくれます。VFDディスプレイの質感も良く、音楽を目でも楽しめる素晴らしいインテリアグッズです。【使用感】15レベルのインジケーターが音に合わせて動く様子は見ていて飽きません。リスニング環境を楽しく彩ってくれるアイテムとしては、非常に満足度が高いです。【注意点（プロ・制作ユースの方へ）】ギタリスト・作曲家としての視点から一点注意があります。個体差もあるかもしれませんが、電源を入れるとごくわずかにノイズが発生します。普段のリスニングや趣味で使う分には全く気にならないレベルですが、レコーディングやミキシングなど、シビアな判断が求められる音楽制作現場では、この些細なノイズが致命的になる可能性があります。【総評】「音楽を視覚的に楽しみたい」という趣味の用途には文句なしでお勧めできます。しかし、制作環境に組み込もうと考えている方は、ノイズのリスクを考慮して検討した方が良いでしょう。用途を割り切って使う分には、最高のガジェットです。 ## Frequently Bought Together - Nobsound AK2515 Pro Audio Spectrum Analyzer with VFD Display, MIC Input & Advanced AGC - Precise Sound Level Meter for Musicians and Audio Enthusiasts - Amazon Basics 3.5mm Stereo Aux to 2 x RCA Audio Cable Adapters, 4 Feet/1.2 m, for Connecting Amplifiers, Speakers, with Gold-Plated Plugs, Black --- ## 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.com.sa/products/379615144-douk-audio-nobsound-music-spectrum-15-level-indicator-vu-meter](https://www.desertcart.com.sa/products/379615144-douk-audio-nobsound-music-spectrum-15-level-indicator-vu-meter) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-09-30*
