LDR volume control
Learn about how LDRs work and how they are used in audio volume control.
LDR calibration
Tortuga Audio preamp owners can initiate self-calibration of their installed LDRs on demand in order to maintain optimal performance and initialize any new replacement LDR.
LDR input & output impedance
Tortuga Audio's LDR preamp attenuators & controllers have the unique ability for users to change their input impedance to optimize their performance.
LDR adjustable impedance
Tortuga Audio LDR stepped attenuators allow for user adjustment of input impedance from 1k-100k to optimize preamp performance.
LDR diagnosis & replacement
LDRs can fail yet are easily identifiable and replaceable with socketed plug-in LDR modules.
