Introduction

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/cafe/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’ watts not to be more than 270 – 280 in total on the taps.) Each zone can have the power split as you please. For example, you can put all 270 – 280 watts into one zone with one volume control. You can also have zone 1 with 100 watts, zone 2 with 60 watts, and the rest of the zones with 120 watts. Just add the total watts up to be under 270 – 280 and you are OK. No complex wiring required like with 8-ohm systems.

With 3 mic inputs; 2 of which have echo control (Mic 2 and Mic 3), 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.

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.

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 280 watts. It does not matter if it is 12 speakers that are 20 watts each or 25 speakers that are tapped at 10 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.

Setup

Selecting Output Wire and Connectors

It is recommended you use high quality 16 AWG, 2 or 4 conductor, heavy gauge, CL2 or CL3 rated, 100% Oxygen-Free Copper (OFC) speaker wire. CL2 and CL3 ratings refer to the cable jacket’s fire resistance and the voltage capacity of the wire. While both cables have the same flame resistance capability, the CL2 cable can handle voltage spikes of up to 150 volts while the CL3 can handle up to 300 volts. When using the 70V/100V speaker zone output screw connectors, use terminal forks up to 10 AWG (recommended) or bare wire. Below is a chart to help you select the appropriate size wire based on the amp to speaker distance.

CAUTION: Never use shielded cable for output wiring.
CAUTION: For low impedance loads only.
CAUTION: Check local code requirements before installing in-ceiling or in- wall speaker wires. We recommend you use CL2 or CL3 rated, Oxygen-Free Copper (OFC) speaker wire.

The RCS350-6 features one RCA line output. We recommend you use high quality RCA cables such as the Rockville RNRTR10, RNRMR, or RCDR series.

Selecting Input cables

There are three ‘1/4″ balanced TRS mic inputs and two RCA inputs on the RCS350-6. We recommend you use high quality 1/4″ TRS cables such as Rockville’s RCXMB, RCXFB, or RCTR series. For recommended RCA cables see the Selecting Output Wire and Connec-tors section above.

Rack Mounting

This unit should be on the bottom of the rack or above any equipment that does not produce heat. Be sure to provide at least 1 RU (Rack Unit, 1.75″) of space above and below. Preferably, the side wall should be at least 2″ from the sides of the amplifier and the back of the rack should be open. This will ensure a source of cool air to all sides of the amplifier.

Connections

The RCS350-6’s 70V and 100V connections can be set up in a variety of ways. Please note that utilizing direct speaker connections and speaker zone connections simultaneously is not recommended and will cause damage to the amplifier and the speakers.

Multi-Zone 70V Speaker Output (Screw Connectors)

You may connect any number of 70-volt speakers to each zone as long as the total output for any one zone does not exceed 100 watts and the overall total output of the zones does not exceed 350 watts. As with the direct outputs, best practice is to allow for about 10 – 20% “head room” or extra power. So, the total output power of the speakers connected to any one zone should not exceed 80 – 90 watts, and the total power output of all the zones combined should not exceed 270 -280 watts.

Muliti-Zone Connection Example

WARNING: Do not use Direct Output (binding post) and Zone Output (screw connector) at the same time. Doing so will cause permanent damage to the amp.
WARNING: When using the multi-zone connections, do not use 8-ohm or 4-ohm speakers. Only use speakers with built-in 70-volt transformers.

70V/100V Direct Speaker (Binding Post Terminals)

You may connect any number of speakers to the 70 or 100-volt direct speaker output binding posts as long as the total wattage does not exceed 350 watts. Best practice is to allow for about 10 – 20% “head room” or extra power to handle any unusual amp requirements such as a deep bass note or a booming finale.

WARNING: Do not use 70-volt and 100-volt connections at the same time. Doing so will cause permanent damage to the amp.
WARNING : Do not use 8-ohm or 4-ohm speakers. Only use speakers with built in 70-volt or 100-volt transformers.

4 to 16-Ohm Direct Speaker Output (Binding Post Terminals)

You can connect two speakers to this terminal as long as the final impedance does not fall below 4 ohms. Although it is possible to connect more than two speakers to these terminals, it is not recommended. Please consult a professional if you intend to do so as incorrect installation could lead to irreparable damage to your amp and speakers.

WARNING: Total impedance 0 CAUTION: We recommend you of your speakers must not be consult a professional if you plan less than 4 ohms. on wiring more than 2 speakers to the 4 to 16-ohm output.
WARNING: Do not use Direct Output (binding post) and Zone Output (screw connector) at the same time. Doing so will cause permanent damage to the amp.

In-Wall Volume Controls

Although the RCS350-6 offers individual zone volume controls, there may be occasions when you may want to adjust the volume of a specific zone without having to return to the amplifier. In-wall volume controls are the perfect solution and they are relatively easy to set up. Below is a general wiring guide to assist you in the installation of in-wall volume controls. As with any installation that requires running wires through your walls, be sure to check local code requirements.

A typical in-wall volume control consists of a face plate with a volume control knob on the front side and a step down transformer with in/out connections on the back side. Keep in mind that these volume controls come in a range of wattage ratings. The control you use must match the wattage of your speakers. You can use a higher rated control for lower wattage speakers, but you cannot use a lower rated control for higher wattage speakers.

In Wall Volume Control Installation

This example shows connections for one zone. You can connect volume controls to any of the 6 zones. Using high quality 16 AWG, 2 or 4 conductor, heavy gauge, CL2 or CL3 rated, 100% Oxygen-Free Copper (OFC) speaker wire, connect the desired zone output’s +/- screw terminals to the IN+ and IN- terminals on the volume control. Next, connect the +/- speaker wires from your speakers to the SP- and SP+ terminals on the volume control. Make sure to observe proper polarity on all connections.

Please note, wall controller wattage rating must match the wattage of the connected speakers.

CAUTION: Check local code requirements before installing in-ceiling or in-wall speaker wires. We recommend you use CL2 or CL3 rated, Oxygen-Free Copper (OFC) speaker wire.
