CROWN PZM - 30GPB pressure zone microphones (2 mics) w/ 2 PX-T Phantom Power Modules

These are a nearly sequential pair of Crown PZM-30GPE, they also have two PX-T Phantom Power Interface Modules. This removes the need for the separate pwer boxes --> Description below. They are fully functioning and the "very good" condition is relative to the fact that they are vintage, and well used. There are cosmetic scratches, nothing deep, and some fuzz from the case is stuck to the bottoms a bit, and the PX-T PPIM have the residue from the original stickers with their serial nuimbers on them. For ~40 years of age they work great! Here is what I found when looking up their serial numbers: Your serial numbers (002844 and 002846) are consecutive, sequential matches (separated by just one unit between them on the factory line). During the initial production run spanning 1980 to 1985, Crown's Elkhart, Indiana facility was hand-assembling these in batches. Reaching the mid-2000s serial range for the specialized export market variants securely places their assembly date right around late 1983. Crown PX-T Phantom Power Interface Module: This genuine vintage module safely regulates standard 12V–48V phantom power from modern audio interfaces down to the specific voltage required by vintage PZM capsules. It serves as a plug-and-play inline power converter that completely eliminates the need for rare, clunky external battery supply boxes.
