Description:
Rockville is proud to introduce our new RCS series of products. The RCS350-6 is a 350 Watt 6-zone rack mountable digital hybrid amplifier/receiver. This amplifier is capable of 70 volt, 100 volt, 8-ohm, and 4-ohm applications. This makes it perfect for use in a Restaurant/Bar/Café/Lounge/School/Conference room or any other setting where many speakers are needed.
This model offers 350 watts at 70 volt or 100 volt and the power can be split up into 6 zones. (Most professionals recommend you not exceed 80% of the amp power, so we recommend your speakers watt not to be more than 300 in total on the taps). Each zone can have the power split as your please. For example you can put all 300 watts into one zone with one volume control. Or you can have zone 1 with 100 watts, zone 2 with 100 watts and the rest of the zones with 25 watts each. Just add the total watts up to be under 350 and you are OK. No complex wiring required like with 8 ohm systems.
With 3 mic inputs; each with echo control, you can use this amplifier for announcements, speeches or even Karaoke night! This model also includes a chime button so you can create a chime sound before making announcements. The RCS series features Bluetooth audio streaming so you can play your favorite music or access a playlist right from your phone! This amp also features both USB and SD inputs allowing you to play audio stored on a USB thumb drive or SD Card. There are also 2-line inputs that allow you to plug in another audio device such as an MP3 player, CD player, TV, etc. This is our new and improved version that now has optical input so you can connect this to a digital source like a television or projector.
Individual volume knobs for each of the 6 zones and volume knobs for each of the 3 mic inputs gives you full control over your system.
The built-in clipping limiter function protects your speakers and the amp from overheating. For further protection there is also a cooling system in this amplifier that will keep the components running cool making the amplifier durable and reliable.
This is our new and improved version with euro-block speaker terminals that make it super easy to install the wires even if the receiver is hidden in a corner. The terminals are detachable and once you connect your speaker wire to the terminal it just clicks into the receiver.
Our goal with the RCS series was to make it possible for anyone to install 70 volt systems on their own without spending thousands of dollars on a contractor. This model makes it a breeze to connect many speakers and multiple external sources. We intentionally use common plugs like RCA and 1/4" on our model to make this more universal and user friendly. With our unique design you can feel confident in your DIY ability when installing our commercial system!
What is 70 volt ?
70 volt systems are the number one choice for any application where you want to install multiple speakers. With 70 volt there are a lot of advantages over 8-ohm systems. One of the main advantages is the simplicity of the wiring as well as how easy it is to match up speakers with the amplifier. For example, with this 350 watt / 70 volt amplifier, you can install speakers that total close to 300 watts. It does not matter if it is 20 speakers that are 15 watts each or 40 speakers that are tapped at 7.5 watts each. You always want your 70 volt amp to have at least 15 or 20% more power than the combined watts your speakers are tapped at. When we say the word tap, what we are referring to are the selectors that many speakers in 70 volt have on them. For example, some speakers might have selectable options of 1.5w, 3w, 5w, 10w. What this does is limit how many watts the built-in transformer on the speaker will allow the speaker to get from the amplifier. What this allows for is full customization of your sound for your space. In a restaurant for example you can tap your dining room speakers at 5 watts, the speakers by the bar area at 10 watts, the ones in the hallway at 3 watts and the speakers in the bathrooms at 1.5 watts. Another great feature with 70 volt is you can mix and match any 70 volt speakers whether they are ceiling speakers, wall mounted speakers, subwoofers, etc.
70 volt systems allow you to run very long lines of speaker wire without signal loss. This makes it ideal when running long speaker leads.
The wiring is simple. You just wire all the positive terminals of the speakers to the positive 70 volt terminals of the amplifier. The negative terminals on the speaker simply get wired to the negative terminals on the amp. You do not have to worry about impedance. The power is constant.
If you want an easy to use feature-rich 70 volt amplifier with a ton of power and 6 zones the Rockville RCS350-6 is your best choice!

About JBL

JBL traces its roots to 1946, when pioneering audio engineer James Bullough Lansing founded the company in Los Angeles, California, initially as James B. Lansing Sound, Incorporated. A veteran of loudspeaker design from earlier ventures like the Lansing Manufacturing Company and collaborations on Hollywood's first practical cinema systems, Lansing infused JBL with his relentless pursuit of acoustic clarity and fidelity. Though he passed away in 1949 amid financial strains, the brand endured under new leadership, accelerating in 1969 with acquisition by Harman International—now under Samsung—fueling global expansion and innovation.

JBL excels across professional and consumer audio realms, renowned for its loudspeakers that dominate studios, touring rigs, cinemas, and home setups. Iconic models like the D-130 woofer, Paragon stereophonic system, and L-100 Century defined eras of high-output sound, while modern lines span portable Bluetooth speakers, wireless headphones, soundbars, and pro monitors. The brand prioritizes robust transducers, advanced horns, and diamond-surround tech over niche components like turntables, DACs, or cables.

Positioned as a mid-tier powerhouse with pro-grade heritage, JBL commands respect among discerning buyers for delivering punchy, reliable performance at accessible prices, bridging live-event energy and home listening without high-end esoterica. Its vintage icons draw collectors, yet contemporary ubiquity in arenas and everyday gear cements market dominance for those valuing scale and excitement over boutique refinement.
