AC power supplier that cleans 100 VAC commercial power supply.

Due to the widespread use of digital equipment, it is possible to suppress the degradation of playback sound by cutting off various noise signals that flow into the 100 VAC commercial power supply.

The U ・ BROS-22 uses a series filter method as a noise cut method.
In this method, a filter consisting of a coil and a capacitor is installed in series with the AC line to eliminate noise signals. In addition, the series filter method is mainly operated in the high-frequency signal region. According to the results of hearing tests, the series filter method cuts the band above 100 VAC / 60 Hz.

The power line for analog audio equipment at the Line 5 AC outlet consists of two low-resistance / high-current choke coils with a built-in low-pass filter that provides 0 attenuation at 50Hz/60Hz, - 3 dB attenuation at 500 Hz, and sharp cut-off at higher frequencies.
The power line for digital audio equipment at the Route 3 AC outlet has a built-in low-pass filter that cuts out high-frequency noise signals.

The AC outlet of the Line 5 for analog audio equipment and the Route 3 for digital audio equipment can be turned ON/OFF independently by the sub power switch installed on the front panel.
The master power switch on the left side of the panel allows you to simultaneously turn on / off the power for a total of eight AC outlets.
The ON/OFF status of these power supplies is indicated by the pilot lamp above the power switch located on the front panel.

The total capacity available from each AC outlet is 1000 VA instantly and 500 VA continuously.
