Route your audio where you need it

Plc1 Rear Sm

Four standard audio inputs and a tape loop allow for up to five audio sources. The fourth input can be internally configured as a Home Theater Bypass Input. Input display uses sequentially illuminated blue LEDs for easy identification from across the room, and an orange LED for tape monitor. Two pair of output jacks are provided for bi-amping, sub-woofers, etc.

Premium parts and construction

Audio signals are switched by highest quality relays with gold-plated contacts, then fed to a custom ALPS® Blue Velvet motorized potentiometer. Circuit boards are gold-plated and assembled with lead-free silver solder for best conductivity. Our beautifully custom machined aluminum chassis, knobs, stainless steel hardware reflect the quality of circuitry inside, and remote functions are duplicated on the front panel for maximum convenience.

Review Dagogo

Sonically, the PLC-1 draws little attention to itself. It’s such a reserved-sounding piece, I did not find myself being drawn unduly to just one segment of the frequency spectrum… The PLC-1 retrieved the vocals in a most satisfactory fashion. If a person has quite a number of older discs where vocals are prominent, then I would suggest mating the PLC-1 and D-200’s with a warmer sounding CD player, since the Channel Islands gear will bring plenty of focusing power.”
