The TOA PM-660U is a desktop paging microphone designed for business and IT environments requiring clear voice transmission. This unidirectional, moving coil microphone offers a balanced 600 Ohm impedance, suitable for integration into professional audio systems. It features a push-to-talk switch with a locking lever, providing control over audio output. The microphone's frequency response ranges from 100 Hz to 10 kHz, optimized for speech clarity. Connectivity is provided via a 2.5-meter (98.43-inch) unterminated 4-conductor (2-shielded) cable, allowing for custom termination based on system requirements. The PM-660U is intended for applications such as public address, intercom, and announcement systems where a dedicated, desk-mounted microphone with a controlled talk function is needed. Its robust construction, featuring a zinc-plated steel wire head and ABS resin main unit, ensures durability in regular operational use.
The PM-660U connects via a 2.5-meter (98.43-inch) unterminated 4-conductor (2-shielded) cable. This design requires custom termination by the installer to integrate with existing audio systems.
The microphone has a rated impedance of 600 Ohms, and it is balanced. This specification is important for compatibility with professional audio inputs.
