Here are some pics of our latest passive preamp, the LDR3.V2. Singled-ended 3 inputs plus 2 parallel outputs. Linear regulated wall-wart PS (115 VAC main only).
It's a re-release of our earlier LDR3 but with updated external look, dual displays, and our latest V2.1 preamp controller board which is out best ever.
Features include auto-calibration of the LDRs (no more drift problems) and also adjustable/switchable input impedance.
Choice of silver or black brushed aluminum bamboo, or custom wood front panels. Sharp looking unit with awesome sound you can only get with LDR technology.
