However, a straight 240V: 12V: 12V does not work and required some extra turns to be hand wound to achieve the open circuit voltage of 18V: 18V. A straight 240V: 18V: 18V winding gives too high an open circuit voltage. Once this bifilar winding of about 46 turns was added to the 12V: 12V to make 18V: 18V open circuit everything works well. The unit provides excellent performance at a good price. The morale is to make sure you have a unit for a working voltage of 240V. The units are available with alternative input voltages.

But it is well made and probably not need of repair for a long while to come. **Q: Can I route this straight from my computer, and equalize any noise output coming from there?** A: No. No. No. You need to find where the hum or noise is coming from. Trying to eq it out is extremely poor audio practice. Thete are lots of things to try inclcludibg lifting AC ground, chassis grounds, etc. Hum is sctually a 60hz feedback loop somewhere. Other noise is probably because you have outputs on equipment too high. Remember, no matter the equipment the higher you set an output the more you've amplified internal noise. People don't thing of a mixer ad an amplifier but it actually is. Your taking the millivolt mic signal and adding gain(amplification) to it. The best practice here is to get your much input to overload then back off till it no longer distorts. This is the beginning of the audio chain. This sets the ultimate noise level. A snare drum much is a good place to start. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***T on 9 May 2017* Once the 115V transformer was changed for one working from 240V it is fine.

Only one thing I wish they put the on-off button on the front not the back, but as the owners manual states, when not in use it uses such a small amount of power that it can be left on at all times. ## Frequently Bought Together - EMB Professional Sound System EB631EQ Graphic Equalizer - Rockville RX230 2-Way Stereo/3-Way Mono Crossover, XLR Input/Output, Adjustable Frequencies, Low-Cut Filter, Compact Design, for DJs and Live Sound Engineers --- ## 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.co.uk/products/329599292-professional-sound-system-eb631eq-graphic-equalizer](https://www.desertcart.co.uk/products/329599292-professional-sound-system-eb631eq-graphic-equalizer) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
