Description:
This is a high quality Full balanced Audio Input selction system that Switches Between any one out of the 4 Balanced Audio Sources Connected, to the Amp / PreAmp. The switching is done with the help of 8 high quality DPDT silver contact Relays (2 per channel). No electronic component is used in the audio path, thus the audio signal remains 100% pure and untouched. The Switching Board is provided with PBT Screw Terminal Blocks . The input XLR terminals on the back panel of the Device can be easily connected to these PBT Terminals with the help of shielded patch cables. The desired input is selected easily by rotating the band switch , which in turn can be mounted to the amplifier's/ preamp's front panel. The band switch PCB features 4 LED's that light up individually as per the input selected

Mounting:
The input selection Relay board can be directly mounted as close as possible to the back panel of the Amplifier / Preamplifer Chassis. This is adviced so that minimum length of patch cable is used and any sorts of interference is also avoided. The input selection switch is of a rotary kind, that is mounted on the front panel of the amplifier / preamplifier.The rotary switch pcb is connected to the selection board by a jumper cable ( provided).This Pcb also features 4 LED's , for which holes have to be made on the front panel.
