LDR

The original LDR3 has been discontinued and is no longer available for sale. The LDR3 has been replaced by the LDR3.V2. 

The LDR3 Passive Preamplifier is a passive (unity gain)  3 input, 2 output  preamp/volume controller that is fully controllable via both a front panel control knob and hand held remote (included).

The LDR3 is part of our LDRx family of passive preamps that employ digitally controlled  audio grade light dependent resistors (LDR’s) for volume control and also for switching line stage inputs.

We believe (and our customers agree with us) that our LDRx technology  renders a truer, cleaner, and more transparent sound than any other volume control technology. The result is astonishing sound at a price that doesn’t force you to choose between an excellent preamp or a new car.
