Product Description
ST-D1400/ST-D1800
This series professional power amplifier adopts advanced Class D power amplifier module and high-efficiency SMPS power module, built-in DSP, fully controlled by digital mode, standard configuration with a USB To PC communication port, only in the standard chassis space of 1U height and 13" depth. Can provide powerful power, this series is mainly aimed at high-demand PA applications.
Features
1.Built-in quality DSP that can accurately do routing, gain, phase, mute, parameter equalizing, delay, frequency division, compression and signal limit.
2.Built-in with PFC, universal operating voltage 90-264VAC. No worry about unstable power voltage.
3.Very light weight, easy to move and install.
4.Soft resonant switching power supply LLC module.
5.Unique peak clipping limiter and ripple Elimination.
6.Nice cooling system. Wind flows from front to rear.
7.Accurate volume control, switch on/off, signal, clip and protection LED light in front panel.
8.Multiple protections against direct current ,over heat, over load, on/off switching, RF, and amplitude limit> Nice cooling system. Wind flows from front to rear.
9.Good choice for applications that need high power output.
