Description
 
Full-scale power level meter incorporating legible large-sized meter.

The output of the music signal which comes out from power amplifier is detected, it points in two meter according to a right-and-left channel, and a Direct reading is possible per watt.

It is connectable with DA-A15direct-current and DA-A10direct-current type power amplifier.

When combining with a rack, the convenient rack-mounted panel is adopted, and the carrying handle is also equipped standardly.
