Rockville RCS650-6 650-Watt 6 Zone 70v Commercial/Restaurant Amplifier/BluetoothRockville is proud to introduce the new RCS series of products. The RCS650-6 is a 650 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 RCS650-6 outputs 650 watts at 70 volt or 780 Watts at 100 volt and the power can be split up into 6 zones. (Most professionals recommend you not exceed 90% of the amp power, so we recommend your speakers watts not to be more than 600 in total on the taps). Each zone can output up to 200 watts and all zones should not exceed 650 watts. If you want all 650 watts into a single zone you can use the direct outputs. If you want to use multiple zones, then you can use the zone outputs. For example, you can have zone 1 with 200 watts, zone 2 with 200 watts, zone 3 with 100 watts, zone 4 with 50 watts, zone 6 with 50 watts. This would total 600 watts which is less than the 650 watts the amp can produce and it's also not more than the 200 watts output each zone can produce.
