Answer:
The amplifier accepts 6 mono mic inputs, 2 auxiliary inputs, stereo L/R feeds, and line inputs, delivering output to 4Ω, 8Ω, 70V, or 100V speaker lines per zone. It powers via standard 220–240V AC mains or 24V DC using two external 12V car batteries (they are not included).
The Hitune TZA-4000EM features extensive multi-source input connectivity and versatile speaker terminal options designed for commercial audio infrastructures:
Input Impedance & Sensitivity:
- 6 × Mono Microphone inputs: 0.6 mV / 4.7 kΩ
- 2 × Auxiliary inputs: 100 mV / 470 kΩ
- Stereo Left/Right inputs: 200 mV / 100 kΩ
- Line Left/Right inputs: 1 V / 50 kΩ
- Preamplifier output: 200 mV / 600 Ω; Line output: 1 V / 1 kΩ
Loudspeaker Taps (per Zone):
- Low-impedance direct taps: 4 Ω and 8 Ω
- Distributed constant-voltage taps: 70 V and 100 V line transformers
Power Redundancy:
The unit supports dual-source electrical operation. It runs on primary AC mains at 220–240V (50/60 Hz, 700VA consumption) or auxiliary 24V DC battery backup via two 12V automotive-grade batteries (they are not included), drawing up to 9A under full DC load.
