The Ahuja TZA-2000 2 Zone Public Address Mixer Amplifier (ERP ref: KTI140020012JAM) is engineered for medium-sized sound installations requiring dual-zone audio management, multi-source mixing, and dependable power routing. Featuring a split power stage delivering 130W + 130W Maximum (100W + 100W RMS at 10% THD), six mono microphone inputs, dual auxiliary inputs, and independent zone switching, the amplifier is deployed across diverse industrial, commercial, and institutional architectures.
Dual-Area Places of Worship and Prayer Halls
Places of worship frequently require separate acoustic coverage for primary prayer halls and auxiliary outdoor courtyards or overflow spaces. The TZA-2000 facilitates independent speaker line routing for two distinct zones:
- Indoor and Outdoor Partitioning: Zone 1 can drive high-fidelity low-impedance (4Ω or 8Ω) speakers inside the sanctuary for natural vocal reproduction, while Zone 2 drives 100V or 70V Line Matching Transformer (LMT) column speakers across long outdoor cable runs.
- Selective Sound Distribution: Dedicated Zone On/Off controls allow facility managers to silence outdoor or auxiliary speakers during smaller services without disrupting the central mix or indoor program audio.
- Multi-Microphone Coverage: Six balanced mono microphone inputs (0.6mV/4.7kΩ) accommodate multiple altar mics, podiums, and choir feeds simultaneously.
Industrial Plants, Warehouses, and Multi-Area Factories
In manufacturing complexes and distribution facilities, acoustic environments vary significantly between operational shop floors and administrative offices. The TZA-2000 handles these varied load impedances and operational environments reliably:
- Split Floor Distribution: Deploy 100V high-impedance ceiling speakers across administrative office corridors on Zone 1, while operating high-output 70V or 100V industrial sound projection horns across high-ambient-noise shop floors on Zone 2.
- Shift Signaling and Paging: The 50Hz to 15,000Hz (±3dB) frequency response and 60dB signal-to-noise ratio ensure clear emergency announcements, operational shift bells, and routine floor paging.
- Mission-Critical DC Failover: In the event of AC mains supply interruption, the amplifier instantly switches to a 24V DC battery backup using two external 12V car batteries (they are not included), maintaining critical factory communication without operational downtime.
Auditoriums, Educational Institutions, and Training Facilities
Schools, colleges, and enterprise training centres benefit from the flexible mixing console architecture and tone contouring capabilities of the TZA-2000:
- Auditorium and Spillover Hall Routing: Deliver high-clarity speech to the main auditorium on low-impedance 4Ω/8Ω cabinet arrays while relaying the identical audio mix over 100V line speakers in foyer areas, green rooms, or secondary briefing rooms.
- AV Integration: Connect dynamic microphones across the 6 mic inputs, connect audio mixers or media players to the 2 Aux inputs (100mV/470kΩ), or interface balanced stereo playback via the dedicated Stereo L/R input (250mV/47kΩ).
- System Expansion: Utilize the integrated Preamp output (200mV/600Ω) or Line output (1V/1kΩ) to route premixed audio signals to secondary booster amplifiers or external recording systems.
