GA500 mini digital amplifier

The GA500 mini digital amplifier is a compact Class D unit that incorporates a built‑in integrative digital power stage. It delivers 300 W per channel into 8 Ω loads at 1 kHz and 600 W per channel into 4 Ω loads, while a bridged configuration can reach 1000 W at 1 kHz. Input sensitivity is 0 dB with a balanced impedance of 20 kΩ and an unbalanced impedance of 10 kΩ. The frequency response exceeds 20 Hz to 20 kHz and the total harmonic distortion plus noise is 0.01 % at 1 kHz, 1 W. The unit runs on selectable 110 V or 220 V AC and includes fuse protection of 20 A at 110 V and 10 A at 220 V. Its net weight is 3 kg and the chassis measures 387 × 155 × 57 mm.

The amplifier uses a digital Class D power stage that typically achieves efficiencies above 90 % and incorporates thermal management with heat‑sink fins. Protection circuits guard against short‑circuit, over‑current, over‑voltage and over‑temperature conditions, which is standard for professional‑grade audio gear. The front panel provides a clear LED indicator and plug‑and‑play connections suitable for non‑technical operators. The chassis is constructed from sheet metal with a powder‑coat finish that meets typical durability expectations for commercial installations.

The GA500 is suited for venues such as commercial sound systems, corporate auditoriums, entertainment halls, schools and military facilities where reliable high‑power output is required. Units can be stacked from one to seven in a standard rack, allowing total system power up to 8420 W in 8 Ω mode or 8400 W in 4 Ω mode, and up to 7000 W when bridged.
