Answer:
The amplifier accommodates 4 dynamic microphones and 1 auxiliary audio source, with outputs for low-impedance (4Ω, 8Ω, 16Ω) speakers and 100V high-impedance distributed line systems.
The Hi Tune 60W PA Mixer Amplifier provides versatile interfacing options for standard public address peripherals:
- Microphone Inputs: 4 × 6.5 mm jack inputs rated at 0.65mV / 4.7kΩ for low-impedance dynamic microphones.
- Auxiliary Input: 1 × Aux input rated at 100mV / 470kΩ for external media players, tuners, or mixers.
- Loudspeaker Taps: Low-impedance taps at 4Ω, 8Ω, and 16Ω for direct voice-coil speaker connections, alongside a 100V line terminal for distributed line-matching transformer (LMT) ceiling or column speakers.
- Pre-amplifier Output: 1 × line-level output (200mV / 600Ω) dedicated to driving booster power amplifiers or feeding external recording equipment.
- Tone Shaping: Cut-type Bass (-10 dB at 100 Hz) and Treble (-10 dB at 10 kHz) controls.
