Each channel Power Module is completely independent and includes separate RCA input and 5-way speaker output binding posts, vacuum tube, rectifier & filter capacitors, electronic components, protection and output power devices, etc. Important: Do not apply power until you have read and understand this section!

The input impedance is a very compliant 47K Ohms which accepts a wide range of signals without undue loading.
