QSC RMX850a เครื่องขยายเสียง 2 channels, 200 watts/ch at 8Ω, 300 watts/ch at 4Ω, 430 watts/ch at 2Ω

The RMX850A is a 300W-Channel @ 4 Ohms stereo power amplifier.

The RMXa Series amplifiers from QSC offer true professional-quality performance at an affordable price. Three 2-rackspace models range in power from 430 to 1200 watts per channel at 2 ohms. Two 3-rackspace models provide 2000 to 2500 watts per channel at 2 ohms. All five models feature a compact chassis less than 16" deep. RMXa amplifiers include a comprehensive set of features including XLR and 1/4" balanced inputs, Speakon® and binding post outposts for convenient connectivity. User-defeatable clip limiters and selectable low-frequency filters optimize sonic performance.

Features:

• High-current toroidal transformers for greater 2 Ohm power and low noise
• Independent user-defeatable clip limiters reduce distortion
• Selectable low-frequency filters (30 Hz or 50 Hz) protect speakers and increase headroom
• Balanced 1/4" (6.3 mm) TRS, XLR, and barrier strip inputs
• Touch-proof binding post and Neutrik Speakon® outputs
• Front mounted gain controls for easy access
• Signal and Clip LED indicators to monitor performance
• Independent DC and thermal overload protection on each channel automatically protects amplifier and speakers
