This processor employs cathode followers to improve your audio system. It outputs the same voltage as it receives. The voltage gain approaches 1. It also adds tube audio quality to digital audio, reduces work load of a receiver (or an amplifier), and makes speakers sound warmer and more finer.
This processor can be connected in various configurations. It is to be installed between an audio source and a receiver (or an amplifer). The audio sources can be a solid state CD/DVD player, MP3 player, iPod, electric guitar, or computer audio output.
Dual power supply voltages are available on this unit, 115VAC for North America, 230VAC for Asia and Europe. The unit is preset at factory for using with 115VAC.
The 6N8P tubes can be replaced with 6SN7.
