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" ## 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? - 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.id/products/379615144-nobsound-music-spectrum-15-level-indicator-vu-meter-screen-amplifier](https://www.desertcart.id/products/379615144-nobsound-music-spectrum-15-level-indicator-vu-meter-screen-amplifier) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-09-08*
