Features and Specifications

DECORA style high-quality auto transformer provides advantages of excellent frequency response, low insertion loss and reliable performance for volume control applications in 25 and 70 volt systems. Attenuation is accomplished in ten make before break steps plus positive off position (no stop between maximum and off position to prevent switch damage). The Attenuator features removable input/output terminal blocks, Two in, two out and two optional for through output for daisy chain option. An attractive alternative to Commercial series attenuators mounts into most single gang E.O boxes. UL Listed White, Almond and Ivory Plastic Plates with Matching Skirted Knobs in DECORA® Style

Power Rating:

The Internal Volume Controls (2) are rated at

100W so the speaker(s) connected to it needs the transformer setting to be equal to or less than the rated watts of each MVC. You can have multiple speakers connected to one MVC but total wattage must 80% or less than the rated Wattage of the each of the internal 100 Watt Volume Controls.

Picking the right Distribution Amplifier:

0 0dB Speaker off

To start with the Amplifier must have a 70Volt output. It must have an output power rating equal to or greater than the total wattage of the system once you have calculated what each speaker should be set to and the total sum of those settings. If you had four speakers at 5 watts each (20 total) and one speaker set to 10 watts (20 + 10 = 30) your amplifier must be rated at least 30 watts minimum. If you had five speakers at 10 watts each (50 total) and another 5 five speakers at 5 watts each (25 + 50 = 75) you would need a amplifier rated at a minimum 75 watts.

Some companies recommend the total should be closer to 80% of the minimum rating of the amplifier. It is also a good idea to install an amplifier with more than enough power in case you want to add more speakers later.

Key Point: The Power rating of the amplifier is determined by the transformer settings, not the attenuator Rating, The rated power of the Attenuator is based upon the minimum setting of the transformer taps which have to be equal to or less than the rated wattage of the respective MVC Attenuator
