It is engineered to connect pre-polarized electret condenser microphones—specifically those configured with a special 3-pin connector (LEMO-compatible SE pinout)—directly to standard, balanced studio and live sound equipment that provides regular 12V to 48V phantom power.\u003c\/p\u003e\n\u003cp data-path-to-node=\"2\"\u003eThe \"P-4\" designation specifies its factory input jack configuration: a specialized 3-pin lockable socket. This makes it an essential utility tool for adapting high-end lavalier and headset microphones (like the MKE 1, MKE 2-4, and HSP 4) away from their usual wireless bodypack transmitters and converting them into wired, balanced XLR microphones.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"4\"\u003eKey Operational and Engineering Attributes\u003c\/h3\u003e\n\u003cul data-path-to-node=\"5\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,0,0\"\u003e\u003cb data-path-to-node=\"5,0,0\" data-index-in-node=\"0\"\u003eActive Signal \u0026amp; Impedance Conversion:\u003c\/b\u003e The internal circuitry steps down high-voltage studio phantom power (12V - 48V) to the lower bias voltage required by miniature capsule elements.
