Those are gain knobs. You wanna crank your receiver up to about 80% volume and then turn the gain knobs up to get maximum volume and sound without clipping. Using the gain knobs for volume increases distortion to speakers. With my set up my receiver goes to a 3 channel eq/ crossover with dedicated subout. Then that runs to 3 different amplifiers. A basic quick set up is my receiver is cranked to 80%max then I adjust my eq for gain on it using built in meter for maximum volume without clipping EQ then move on to Amp. Besides my sub amp my other two set somewhere between 12 and 22 gain. The amps peak power is not determined by how high you crank gain. But those are not volume knobs. **Q: What about the power source? is it autovolt?** A: no **Q: Does anyone know the true rms on rpa16?** A: What’s written in the specs is pretty accurate. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very good for the price.

While the sound quality comes no where close to top brands, if you just a hobbyist musician simply wanting something powerful but on a budget, this isn’t the absolute worst brand to consider in my opinion. I bought this amp (RPA12) because I needed a more powerful amp than what I currently to properly drive the subs (which are also 18-inch Rockvilles) of my PA system. When I connected the RPA12 to my subs, it definitely provided much powerful deep end with the X-over switch set to the lowest frequency setting. However, the issue I had is that when I tried to set the gain anywhere past the 10 o’clock position, it clipped…even with my mixer set at 0 db. For me, this wasn’t that big of an issue because I was still getting enough low end on my overall PA volume. Plus, I really couldn’t find another amp with these specs at this price range; especially one that included a crossover switch. It’s just incredibly disappointing not being able to fully crank this amp to see how much rumble I could potentially get from my subs. I did notice another reviewer had a similar issue. So just beware with this model line of amps. You might not get the power output you’re expecting. Update: since my original review, I discovered the 1/4” input jack on one of my 18 subs shorted out. This is why I was getting the clipping signal at such a low db setting. The Speakon jack still worked so I just hooked it up from there and I had a ton of power coming from the amp at that point. So I would definitely recommend this amp to anyone who wants a massive amount of power but stay within a budget. ## Frequently Bought Together - Rockville RPA12 5000W Peak/1400W RMS 2 Channel Power Amplifier, High Output, Bridgeable, LED Indicators, for Pro DJs and Live Sound - Yuyaokk 2Pack 25 ft Speakon to 1/4" Male Speaker Cables, Professional 12 Gauge AWG Wire Audio Amplifier Connection Cord, DJ/PA Wire with Twist Lock. - Rockville (2) RSG12 12 3-Way 1000 Watt 8-Ohm Passive DJ/Pro Audio PA Speaker --- ## 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.jp/products/112239165-rockville-rpa12-2-channel-professional-dj-rack-mount-power-amplifier](https://www.desertcart.jp/products/112239165-rockville-rpa12-2-channel-professional-dj-rack-mount-power-amplifier) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-30*
