About the 540P

The Azur 540P is a stereo moving-magnet (MM) phono preamplifier designed to connect a turntable to a line-level input. It uses discrete-transistor input stages and a single-ended Class A gain stage with passive RIAA equalization. The 540P is MM-only; the related Azur 640P is a different model and adds moving-coil capability.
