Passive design with direct insertion provides a lossless signal path for input and output signals, with no power required. Six stereo input channels allow you to connect multiple sources to a single output that feeds an amplifier or active speakers. Examples of compatible sources include TV audio, MP3 players, CD players, video games, mobile phones, tablets, computers, and record players. The six-channel audio signal selection switcher eliminates constant plugging and unplugging by uniformly connecting each source to the switcher for easy, reliable source selection. Use scenarios - Living room / home theater: route TV audio, game console, and streaming device to a single amp or active speakers. - Desktop or studio monitoring: switch between computer audio, CD player, and turntable for monitoring on speakers. - Mobile device playback: connect a smartphone or tablet to play music through a single speaker system.
