Public Address Amplifier and Audio Mixer Compatibility
The Ahuja ACM-96 desktop paging microphone is engineered for direct electrical integration with standard commercial public address (PA) amplifiers, preamplifiers, booster units, and audio mixers. Designed around a 600 Ohm nominal impedance rating, the dynamic transducer matches standard medium-impedance dynamic microphone input stages across single-zone and distributed sound systems without requiring intermediate impedance matching transformers.
Because the unit utilizes a high-performance unidirectional dynamic cartridge, it operates as a passive acoustic transducer that requires no external phantom power or line-level preamplification at the console end. This architecture ensures universal compatibility with mono and multi-channel PA mixer amplifiers, commercial background music/paging controllers, and integrated commercial sound consoles equipped with dynamic microphone input channels.
Input Termination and Cabling Architecture
Hardware connectivity is established through the factory-supplied 6-meter twin-core shielded low-noise cable. Terminated with a standardized 6.3 mm (1/4") mono phone plug, the assembly allows direct plug-and-play connection into standard 6.35 mm microphone input jacks commonly found on commercial amplifier front and rear panels.
The 6-meter cable length and twin-core shielded construction provide effective rejection against electromagnetic interference (EMI) and radio frequency interference (RFI), maintaining signal integrity across dispatch desks, reception counters, security control stations, and industrial podiums where routing proximity to electrical conduits and office automation equipment is necessary.
Acoustic and Electrical Matching Parameters
The ACM-96 delivers a sensitivity rating of 2.0 mV/Pa coupled with an operational frequency response spanning 50 Hz to 10,000 Hz. This frequency curve is tailored specifically for the speech intelligibility bandwidth, ensuring seamless integration with standard speech-band equalization, high-pass filtering, and limiter/compressor circuits on industrial paging processors.

Paging Control and Single-Zone Integration
Designed as a single-zone desktop solution, the unit integrates high-reliability operating switches directly onto its heavy-duty aluminium die-cast top base:
- Momentary Press-to-Talk Operation: Enables quick, momentary live announcements with immediate release muting.
- Lockable TALK Switch: Allows hands-free continuous operation for extended addresses, briefings, or long dispatch transmissions.
- Integrated LED Indicators: Provides clear operational status verification during active microphone transmission.
