GA FA-2500D

Описание

1. High-efficiency inverter-type energy-saving switching power supply with ultra-efficient Class D low-power digital power amplifier;

2. Features a 1U chassis with a black and gold high-grade stainless steel panel design, occupying only 19-inch rack space, minimizing footprint and heat generation;

3. The panel includes independent green and orange LED indicators for signal, protection, peak clipping, and output signals, and a blue indicator for power input. 4. Complete protection functions including short circuit, overload, high temperature, peak clipping, and DC protection;

5. Built-in low-cut voltage limiter effectively filters out unwanted frequency response 20Hz-20kHz music signals; more stable and reliable, clearer sound!

6. Dual balanced/unbalanced audio input with balanced signal input, dual-channel rated power 2*500W;

7. Independent input gain control with signal amplitude adjustment and compensation (-3dB -0dB adjustable VOL LEVEL);

8. Constant voltage/constant impedance dual switching to balanced voltage output (8Ω/100V), compatible with 4-16Ω constant impedance speakers;

9. Active channel with high-impedance filter and DIP switch for clearer and brighter IF in broadcasting;

10. Automatic temperature-controlled cooling fan for forced air cooling. The cooling fan draws in air from the front and exhausts it from the back; do not obstruct the intake and exhaust ports.

10. Equipped with a DC24V power input port, switchable between 110V and 230V AC input. Features voltage range protection (20~27.5V) to prevent backup battery failure due to prolonged power depletion.

11. Equipped with XLR balanced input (+-= 100V : S+=8Ω) using Phoenix terminals.

12. Built-in automatic standby function saves power. When there is no audio signal input, the power amplifier circuit stops working, while the power supply circuit continues to operate, thus saving energy, reducing temperature rise, and extending product lifespan. Automatically exits energy-saving mode when a signal is input.
