4 Way Audio Input selector board for Bulk Head tiffany style RCA  

Highlights:

• Switches easily between 4 stereo audio signals.
• The Audio Signals are routed unaltered in any way right from the Input terminals to the Amplifier Board ,no electronic parts are used in the Audio Signal Path.
• Fully independent Power ground and Signal Ground 
• Specially designed Board For Bulk Head Tiffany Style Rca Sockets.
• No patch cables are required for the input signals as the RCA sockets are directly mounted to the PCB.
• High Quality Parts Used throughout. 
• Signal Selector switch can be independently mounted on the front panel.

Part Details :

• 4 High quality HUIKE Silver Contact Relays.
• ELNA Capacitors
• FR4 grade glass-reinforced epoxy 2.0mm thick board with Gold immersion , high grade Black soldermasking and 2OZ copper foil thickness. 
• High quality long life band switch.

Description:
This is a high quality Stereo Audio Input selction system that routes any one out of the 4 audio Inputs connected, to the Amplifier's input. The switching is done with the help of 4 high quality DPDT silver contact Relays (1 per channel), these relays route the connected audio signal to the Amplifier/Preamp board's input input as these are turned on with the help of a band switch. No electronic component is used in the audio path, thus the audio signal remains 100% pure and untouched. The Board ihas been specially developed to work with the bulk head type RCA sockets as found only on very high end branded audio devices. The RCA sockets can be directly soldered on to this board and easily mounted on the back panel with the RCA socket nuts only. The desired input is selected easily by simply rotating the band switch , which in turn cand be mounted to the amplifier's/ preamp's front panel. . The band switch PCB featured 4 LED's that light up individually for each input selected.

Mounting:
This input selection board is designed to work with the bulk head RCA sockets . The Relay Board can be directly mounted on to the devices's back panel with the help of the RCA oscket nuts. All the 8 nuts are first removed and this board is inserted into the back panel predrilled holes from the inside of the chassis. Once the board is its place along with the insulating washers the nuts are tightened back on to all the 8 induvidual RCA sockets from the outside of the chassis.The input selection switch is of a rotary kind, that is mounted on the front panel of the amplifier / preamplifier very easily just by drilling a hole for the rotary switch .The rotary switch pcb is connected to the selection board by any 5p jumper cable.This Pcb also features 4 LED's , for which holes have to be made on the front panel.
