Answer:
The amplifier supports low-impedance 4Ω and 8Ω speaker loads as well as 70V and 100V constant-voltage lines. It accommodates 7 microphone inputs (0.8mV/4.7kΩ), 2 auxiliary inputs, and a dedicated 1V Line input for external mixers.
The Hitune Bass HSSA-350 PA amplifier is equipped with versatile input and output stages to interface with diverse industrial and commercial audio equipment:
- Input Channel Connectivity:
- 7 × Microphone Inputs: Rated at 0.8mV sensitivity and 4.7kΩ input impedance, designed for low-impedance dynamic microphones.
- 2 × Auxiliary Inputs: Aux 1 (200mV / 470kΩ) and Aux 2 (100mV / 470kΩ) for standard background music players, tone generators, or line-level source gear.
- 1 × Line Input (1V / 50kΩ): Enables direct patching from the master output of an external mixing console, permitting the HSSA-350 to function as an independent booster power amplifier.
- Speaker Output Terminations:
- Low-Impedance Taps: Direct connections for 4Ω and 8Ω loudspeaker networks, suitable for close-coupled sound boxes.
- High-Voltage Distributed Lines: Dedicated 70V and 100V speaker line taps for long-distance distributed paging runs utilizing line-matching transformer (LMT) ceiling speakers, sound columns, and reflex horns.
