Color: White (paintable) RockvilIe is proud to introduce the first commercial amplifier in our new RCS series of products. The RC60-1 is a 60 Watt single zone rack mountable digital hybrid amplifier/receiver. This amplifier is capable of 70 volt, 100 volt, 8 ohm, and 4 ohm applications. The RockvilIe CCL5T is a great choice for any restaurant, office, school, retail store, or any other commercial application. This speaker will sound great for all your PA announcements, and background music. There are 3 inputs so you can select how loud you want them to play. What is 70 volt 0 volt systems are the number one choice for applications where you want to install many 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, you can buy one 70V amplifier with 150 watts and you can install speakers that total around 120 watts. It does not matter if it is 24 speakers that are 5 watts each or 48 speakers that are tapped at 2.5 watts each. You always want your 70 volt amp to have at least 15 to 20% more power than the combined watts your speakers are tapped at.
