Answer:
The HSSA-300BT connects to low-impedance 4Ω and 8Ω speakers or 70V and 100V constant-voltage lines. It accepts 6 microphone inputs, 2 auxiliary sources, 1 line input for booster chaining, and features built-in USB/SD/FM/Bluetooth media playback.
The Hitune HSSA-300BT provides versatile input and output interfacing for plant-wide, multi-zone, or single-zone PA installations:
- Speaker Output Terminals: Supports direct connection to low-impedance loads via dedicated 4Ω and 8Ω taps, as well as 70V and 100V high-impedance taps designed for long cable runs driving speakers equipped with line matching transformers (LMT).
- Microphone & Line Inputs: Equipped with 6 microphone inputs (0.65 mV / 4.7 kΩ), 2 auxiliary line inputs (100 mV / 470 kΩ), and 1 dedicated Line input (1V / 50 kΩ) for patch cords from external audio consoles.
- Amplifier Expansion: Features a Preamplifier output (200 mV / 600 Ω) and Line output (1V / 1 kΩ) to slave additional booster power amplifiers or send line-level feeds to recording equipment. Using the Line input allows the HSSA-300BT itself to function as a slave booster amplifier.
- Integrated Digital Media: Includes an onboard MP3 module supporting USB pen drives, SD/MMC storage cards, FM radio, and wireless Bluetooth streaming, operated via front-panel controls or the supplied remote control. Any remote cells/batteries (they are not included) must be sourced separately.
- Power Redundancy: Features instant failover to an external 24V DC battery (they are not included) during AC mains disruption to maintain continuous communication.
