The Hitune Bass HTZA-2000 two-zone PA mixer amplifier (KTI140020012JAH) is engineered for commercial, industrial, and institutional sound reinforcement systems where distinct audio zones and balanced multi-source mixing are required. Providing 100W RMS per zone (130W maximum per zone, 200W total rated power), the unit delivers flexible deployment options across low-impedance (4Ω, 8Ω) and high-voltage line-distributed (70V, 100V) speaker networks.
Segregated Indoor and Outdoor Sound Distribution
Facilities that encompass both enclosed rooms and open exterior spaces frequently require split acoustic power management. In standard public address architectures, driving outdoor horn speakers and indoor box or ceiling speakers on a single amplifier channel results in uneven sound pressure levels. The HTZA-2000 solves this through dedicated dual-zone controls:
- Indoor Acoustic Spaces: Zone 1 can be assigned to interior spaces utilizing the low-impedance 4Ω or 8Ω taps, or 70V/100V ceiling speakers, calibrated for clear speech intelligibility at lower ambient sound thresholds.
- Outdoor Perimeter and Courtyards: Zone 2 can independently power 70V or 100V line-matching transformer horn speakers positioned across perimeters, parking lots, or verandas at elevated volume levels without distorting or overdriving indoor zones.
Places of Worship and Congregational Venues
Houses of worship require versatile microphone connectivity and dual-coverage distribution. The HTZA-2000 facilitates simultaneous mono operation across two distinct groups of loudspeakers, making it suitable for prayer halls, sanctorums, and spillover verandas:
- Multi-Microphone Configurations: With 6 dedicated microphone inputs (0.6mV / 4.7kΩ), the unit accommodates multiple altar, pulpit, choir, and roaming microphones simultaneously.
- Acoustic Fine-Tuning: Onboard tone controls offering Bass adjustment (±10dB at 100Hz) and Treble adjustment (±10dB at 10kHz) allow technicians to tailor speech frequencies across the 50 Hz to 15,000 Hz (±3dB) frequency response range, reducing low-end reverberation in resonant sanctuaries.
- Auxiliary Chime and Media Integration: Two auxiliary inputs (100mV / 470kΩ) and a stereo L/R input (250mV / 47kΩ) support external media playback, recorded chimes, or musical instrument feeds.
Educational Campuses and Institutional Complexes
In school campuses, training centers, and administrative complexes, public address requirements split between general announcements and dedicated auditorium audio. The HTZA-2000 functions as a central audio hub where:
- Zone 1 addresses classrooms or hallways via 100V line ceiling speakers for daily announcements and bell tones.
- Zone 2 feeds the campus quadrangle, assembly grounds, or athletic courts using high-output outdoor horn speakers.
- Auxiliary and stereo inputs connect directly to media players, computer audio interfaces, or pre-recorded announcement systems for automated scheduling.
Industrial Plants with Uninterrupted DC Power Backup
Factory floors, warehouses, and distribution centers require public address equipment that remains operational during utility grid failures. The HTZA-2000 incorporates dual-supply capability, running on AC mains during regular operation and seamlessly accepting a 24V DC battery power supply (they are not included) for emergency paging and continuous plant communication.
