Can you help?** A: There is a button that says EQ , if you do not engage the EQ your in bypass mode and there will be no Equalization . So press that button , but turn the volume to a lower level , because when the the EQ is engaged the volume will bump up . And also make sure your connections are correct, stereo out to EQ in . If your not sure if your hook up is correct refer to you Stereo owners manual. **Q: I realize that this unit does not have a spectrum analyzer, but where are the dual vu meters that are listed three times in the description?** A: It has no VU meters. **Q: How does the spectrum analyzer work** A: It's fake- it doesn't represent anything other than the overall level with a completely made-up representation of frequencies. **Q: i have a sherwood receiver and yamaha speakers for outside deck,would this eq work for this?** A: Depends upon the inputs and outputs for your receiver. Also depends upon whether your receiver supports an equalizer loop. Also depends upon whether you pipe other sources into your receiver or not. Don't take this equalizer outdoors, of course. ## Frequently Bought Together - Rockville REQ42-B Black 19" Rack Mount 2 x 21 Band Equalizer - Tan QY 2RCA to 2RCA Cable 3Ft, Gold-Plated 2 RCA Male to 2 RCA Male Stereo Audio Cable for Home Theater, HDTV, Gaming Consoles, Hi-Fi Systems (3Ft/1M) - Monoprice 1.5ft Premium 2 RCA Plug/2 RCA Plug M/M 22AWG Cable - 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.pe/products/5110809-rockville-req42-b-black-19-rack-mount-2-x-21](https://www.desertcart.pe/products/5110809-rockville-req42-b-black-19-rack-mount-2-x-21) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-08-22*
