This is a Light Dependant Resistor 3 Input passive preamp kit.Providing the very best in audio quality, far surpassing other forms of attenuation. You might as well have the best. The kit comprises a assembled control circuit board, a assembled stereo LDR circuit board containing facility for 3 RCA stereo inputs made up of 8 NSL32SR2 matched LDR's and a stereo output , a 500k Bournes potentiometer, a switch and full instructions are provided on email. The kit comes unwired, there are connector blocks for all connections, that just require a small screwdriver, and you will need cable to wire the kit up. The kit is easy to wire up, the instructions carry all the information you need, we also provide 24/7 email help.

LDR's when matched are the best method of achieving a passive attenuator. We supply the NSL32SR2s LDR which is a selected LDR. The attenuator simply stated is a volume control of very high quality, as there are no switches or switch contacts wiping to distort audio quality, rather nothing more than light activates a variable resistor. The LDR board is now provided with trim pots that enable precise left right balance Image of pot shows the linear 500k, we supply the audio taper 500k Bournes potentiometer

Unsupplied: 12 volt Power Supply, screwdriver and cable. let us know if you require the RCA blocks pictured in the final image, as most kit constructors prefer to wire the LDR board rather than fit them.
