LDR3 Passive Preamp
$1,195.00The 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 The LDR3 has been replaced by the LDR3.V2.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.

The encoder module is normally included as part of the OLED display assembly which you can purchase here, but we also offer it as a stand-alone item in can you need a replacement for any reason.
Since inception, all Tortuga Audio preamp controllers and other preamp products have utilized a rotary encoder with integral push button as a means for manually controlling the preamp device. While limited in control functionality as compared to using an infrared remote control, the encoder has typically provided a means to control volume, power on/off, mute/unmute, channel balance, and even select between audio input sources.
