Introduction

Rockville is proud to introduce the first commercial amplifier in our new RCS series of products. The RCS80-1 is a 60-watt, single-zone, rack-mountable digital hybrid amplifier/receiver. This amplifier is capable of 70-volt, 100-volt, 16-ohm, 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 multiple speakers are needed. With the dual mic inputs you can use this amplifier for announcements, speeches, or even for Karaoke night! The RCS80-1 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 two microphones, MP3, and line inputs allow for full and autonomous control of this amplifier. The built-in cooling system in this amplifier will keep the components 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 acontractor. This model makes it a breeze to connect many speakers and multiple external sources. We intentionally use common plugs like RCA and ¼˝ 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 60-watt  /70-volt amplifier, you can install speakers that total close to 50 watts. It does not matter if it is 10 speakers that are 5 watts each or 20 speakers that are tapped at 2.5 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.

Setup

Selecting Output Wire and ConnectorsIt 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: 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.

CAUTION: For low impedance loads only.

The RCS80-1 features one RCA line output. We recommend you use high-quality RCA cables such as the Rockville RNRTR10, RNRMR, or RCDR series.

Selecting Input cablesThere are two ¼˝ balanced TRS mic inputs and two RCA inputs on the RCS80-1. We recommend you use high quality ¼˝ TRS cables such as Rockville’s  RCXMB, RCXFB, or RCTR series. For recommended RCA cables see the Selecting Output Wire and Connectors section above.

Rack MountingThis 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 sidewall 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 RCS80-1’s 70V and 100V connections can be set up in a variety of ways. Please note that utilizing 70/100-volt connections and 4 to 16-ohm connections simultaneously is not recommended and will cause damage to the amplifier and the speakers.

70V/100V Speaker OutputYou may connect any number of speakers to the 70 or 100 volt speaker output as long as the total wattage does not exceed 60 watts. Best practice is to allow for about 10 – 20% “headroom” or extra power to handle any unusual amp requirements such as a deep bass note or a booming finale.

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

4 to 16-Ohm Speaker OutputYou 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 of your speakers must not be less than 4 ohms.! WARNING: Do not use 70/100v and 4 to 16-ohm connections at the same time. Doing so will cause permanent damage to the amp.! CAUTION: We recommend you consult a professional if you plan on wiring more than 2 speakers to the 4 to 16-ohm output.
