Ótima qualidade e equalização eficiente. Analisador de espectro só mede o volume de áudio, não por faixa de equalização. Bonito equipamento. Review: It Works. - Of course, this is not the best of the home equalizer I have owned. This is the cheapest of them as I paid a lot more for the other ones. Simply, it does its job and I like it. Too many bands to adjust compare to my old ones (I still have one of them in use), therefore it is just a matter of practice to get used to that many controls to adjust. The spectrum analyzer is just an indicator of the input level not by frequencies but the overall sound, that is why it moves all the bars the same way always but it really responds to the overall sound input level. Another thing, most of the superior equalizers for sale, are more suitable for PA systems not necessarily for your home system but this one is. Even some people criticized the instruction manual, I don't need any kind of instructions to set up an equalizer to my home system, it is so basic. Recommended product for those who don't want to spend a lot of money and have some kind of experience in setting home stereo equipment instinctively, no instructions. ## Features - PRECISE AUDIO CONTROL:- Dual 21-band equalizer (42 bands total) allows detailed sound shaping across 20-20,000 Hz, ideal for tailoring music, movies, or live performances to your preferences. - VERSATILE CONNECTIVITY:- Features RCA stereo inputs for DVD, tape, tuner, or aux-MP3, plus a front-panel 3.5mm input for iPod/MP3 players, ensuring compatibility with various audio sources. - VISUAL MONITORING:- Blue LED sliders and dual VU meters provide real-time feedback for accurate adjustments, while the multi-color LED display adds a professional aesthetic to your setup. - RACK-MOUNTABLE DESIGN:- Lightweight at 6 lbs with removable 19” rack brackets, this equalizer integrates seamlessly into home theater, DJ, or studio racks for a clean, organized look. - HIGH-QUALITY PERFORMANCE:- Delivers clear audio with an 80dB signal-to-noise ratio, minimizing distortion and maximizing sound clarity for both casual listeners and audio professionals. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00LZDVIMK | | Best Sellers Rank | #144,588 in Electronics ( See Top 100 in Electronics ) #14 in Home Audio Graphic Equalizers | | Item model number | REQ42-S | | Manufacturer | Audiosavings | | Product Dimensions | 48.26 x 30.48 x 15.24 cm; 1.7 kg | ## Images ![Rockville REQ42-S Silver 19" Rack Mount 2x21 Band Equalizer w/Spectrum Analyzer - Image 1](https://m.media-amazon.com/images/I/612xv49X-zL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Equalizador Rockville *by L***. on 4 July 2025* Chegou muito bem embalado dos EUA.
