2-Channel Power Amplifier

2U standard
Large energy power supply , high-efficiency and super ring transformer
With protection, signal, clip, bridge and power LED
Lift and right channel with dual polar cooling fan, high- efficiency air cooling channel
With a power star soft, DC protection, short protection, thermal protection, overload protection
Equipped with dual input options (XLR male and XLR female) and dual output options (SpeakON), this professional amplifier series is designed to adapt to various system installation requirements.
This device features three operating modes: STEREO (A and B work independently), PARALLEL (for easy wiring), and BRIDGE (for high-power amplification).
