To choose the appropriate tap setting for the Rockville CT80 8" 70V Subwoofer, you need to consider the total wattage of your speaker system and the power output of your amplifier. The tap setting determines how many watts the built-in transformer will allow the subwoofer to receive from the amplifier.
Here's a step-by-step guide to selecting the tap setting:
1. Determine the total wattage of your speaker system: Add up the wattage of all the speakers in your system that will be connected to the amplifier.
2. Ensure your amplifier has sufficient power: Your 70-volt amplifier should have at least 15% to 20% more power than the combined watts of your speakers. For example, if your speakers total 175 watts, you should have an amplifier with at least 200 watts.
3. Set the tap setting on the CT80-SUB: The CT80-SUB has tap settings for 70-volt and 100-volt input. For 70-volt input, the taps are set at 10, 20, and 40 watts. For 100-volt input, the taps are set at 15, 25, and 55 watts. Choose the tap setting that matches the power output of your amplifier and provides enough power for your subwoofer.
4. Customize the sound for different areas: One of the advantages of 70-volt speakers is the ability to customize the sound for different areas. For example, in a restaurant, you can tap the dining room speakers at 20 watts, the outside seating area speakers at 40 watts, and the hallway and bathroom speakers at 10 watts.
Remember to always refer to the instruction guide and consult with technical support if you have any specific questions or concerns about setting up your 70-volt speaker system with the Rockville CT80-SUB subwoofer.
