Dual-Zone Commercial Facilities and Split Indoor/Outdoor Installations
The Ahuja TZA-7000 is engineered for commercial, industrial, and institutional premises requiring independent acoustic control across two segregated zones. With a dual-channel design delivering 350W + 350W RMS (up to 500W + 500W Max), system engineers can balance sound pressure levels separately between internal spaces (such as workshops, office corridors, or dining halls) and external areas (such as loading bays, parking zones, or perimeter grounds).
Each zone features dedicated Zone On/Off controls and independent low-impedance (4Ω, 8Ω) as well as high-impedance (70V, 100V) line-matching output taps. This flexibility allows facility managers to drive high-fidelity box speakers indoors while running distributed 100V horn speaker arrays over long cable runs outdoors without impedance mismatching or signal degradation.
Places of Worship, Auditoriums, and Multi-Room Conference Venues
In large gathering environments such as houses of worship, community halls, lecture theaters, and auditoriums, public address clarity and speech intelligibility are paramount. The TZA-7000 supports Mono operation to drive two separate loudspeaker clusters simultaneously from shared input sources, accommodating speech delivery across primary sanctuaries and overflow courtyards.
- Extensive Microphone Connectivity: Features 6 Mono Mic inputs (0.6mV/4.7kΩ) and 2 Mono Aux inputs (100mV/470kΩ) for podium microphones, roving vocal mics, and instrument feeds.
- Acoustic Optimization: Equipped with responsive Bass (±10dB at 100Hz) and Treble (±10dB at 10kHz) tone controls, alongside a ≤2 dB output regulation from no-load to full-load at 1kHz.
- Audio Archiving: Dedicated preamplifier output (200mV/600Ω) enables direct feeds to recording consoles for archiving sermons, proceedings, or meetings without disturbing live speaker levels.
Horn Driver Protection in High-Ambient Industrial and Public Alert Systems
Facilities utilizing outdoor horn drivers and acoustic paging units benefit from the amplifier's integrated Box Speaker / Driver Unit selector switches. Switching to the Driver Unit mode automatically defeats low-frequency bass boost, safeguarding horn driver diaphragms from excessive mechanical excursion and thermal stress caused by low-end rumble.
DJ Programmes and Commercial Music Playback
The TZA-7000 provides a dedicated Stereo music operation mode tailored for DJ setups, commercial event sound reinforcement, and high-output background music systems. It accepts Stereo L/R inputs (200mV/100kΩ) and Line L/R inputs (1V/50kΩ) from media players, DJ mixers, or signal processors. Visual monitoring is maintained in real time via the integrated front-panel LED Bar Graph signal display.
Mission-Critical PA with Uninterrupted Battery Backup
For high-reliability safety and industrial installations requiring continuous communication during utility power outages, the TZA-7000 features dual-power operational support. The amplifier runs on standard AC mains (220–240V 50/60Hz, 1100VA) and incorporates instant, automatic changeover to 36V DC operation via 3 × 12V car batteries (they are not included), drawing 13A under full DC load. Equipment protection is reinforced by a built-in resettable circuit breaker against short-circuit and overload conditions.
System Expansion and Booster Amplifier Interfacing
For expansive industrial campuses requiring more than 700W total amplification, each zone of the TZA-7000 includes dedicated Line Input and Line Output (1V/1kΩ) jacks. This enables audio engineers to slave external booster power amplifiers or loop in external multi-channel audio mixers without requiring external signal splitters.
