Grundig GCM 319 (1960s–1970s)
The Grundig GCM 319 is a vintage microphone, most likely from the late 1960s or early 1970s. The record is fuzzy on the exact year. Sources point to "1969," "the 60's/70's," and a Grundig technical information document dated 5/73. It was made in Germany. The original box says it was "mainly designed for use with tape recorders," and notes compatibility with Grundig machines like the TK 545 and TK 745.
The GCM 319 is a cardioid condenser microphone with a metal, chrome-finished case. It has no internal battery. Power comes from the connected device, 4.5 to 20 volts through the centre pin of the attached 5-pin DIN cable. Impedance is rated at 1 kOhm. One listing calls it a "dynamic stereo table microphone" and says it came with a small tripod, instruction manual, and original box. The more consistent description across multiple sources is cardioid condenser, so the dynamic label is likely a mistake.
Surviving documentation is thin. No frequency response, sensitivity, or dimensional data has surfaced, and there is no confirmed original price. Asking prices on the secondhand market run from about €39 to €45, with one Russian listing at 2,000 rubles. Units turn up with some regularity on eBay and Reverb. A YouTube video shows a "Custom" modified example, and another compares the GCM 319 against pairs of Grundig GCM 332s, though no conclusions from that comparison are recorded.
