Answer:
The Hitune MPA-40U connects to 4-ohm low-impedance PA horns or speakers, standard low-impedance dynamic microphones (1 mV / 4.7 kΩ), Bluetooth or USB media inputs, and any stable 12V DC power source such as an automotive battery (they are not included).
System integrators connecting peripheral equipment to the Hitune MPA-40U mobile PA amplifier should adhere to the following interface parameters:
- Loudspeakers: Designed for low-impedance installations matching a direct 4-ohm load, including standard mobile horn speakers and outdoor public address drivers.
- Power Source: Requires a nominal 12V DC direct current supply, specifically compatible with car, van, or utility vehicle electrical lines and 12V storage battery banks (they are not included).
- Microphone Terminals: Accommodates dynamic PA microphones matched to an input sensitivity specification of 1 mV / 4.7 kΩ.
- Digital Playback Inputs: Compatible with standard USB storage drives formatted with audio files and Bluetooth-enabled mobile or broadcast audio transmitters.
