1. A portable active speaker with volume control,Treble/Bass control and AUX in/output with
volume control, PLL wireless module and extending speaker output.
2. Using AC 220V or 110V power that contains RMS 75 Watts(4Ω) output.
3. Adopting bi-amp design with high quality active crossover, and 8-inch woofer that provide
the best sound quality.
4. The power amplifier uses IC circuit design that not only provides high efficiency and better
sound quality, but also protects overheat and short circuit.
5. Adopting high-quality, toroidal transformer design.
6. Using medium-density wood fiberboard as the speaker box.
7. Detachable wheels and trolley create the convenience for free moving.
8. Equipped with stand insert for heightening use.
9. PLL UHF wireless microphone system, which is able to reach over 80M without any
interference.
10. Two sealed lead-acid batteries with automatic charging design.The charger will be
activated immediately when AC power is plugged in,and AC power switch is in "ON" .
11. Two rechargeable batteries with 12V/5Ahr capacity each that could be used over 3.5 hours
with in general volume & over 7.5 hours with normal volume.
12. Uninterrupted power supply (UPS) design that will automatically switch to DC battery without
any effect when pulling out the AC power cable.
13. Two-steps LED charger indicator (Red and Green LED) with low voltage detection. It
would flash red light when charging, light red when full charged, and would light
green when the voltage is normal, and flash green light under the low voltage.
Notice:
1. Please charge the rechargeable batteries more than 8 hours for first time operation.
2. Please refresh the batteries every three months when not using. The batteries will be
damaged if left unused for a long time. (over three months)
3. Refresh the rechargeable battery before operation each time to ensure the best performance.
