The VP-D series are designed to meet the specialized needs of sound contractors. The main voltages can be used DC 24V or AC 110V-240V. Products provide direct 70V/100V capability ranging from 120Watt, 240Watt and 420Watt for distribute audio systems with high thermal capacity and proven reliability.
The VP-D series also provide low-impedance outputs 4 ohm and 8 ohm for maximum flexibility. Amplifiers provide protection by short circuit and open circuit proof and thermal sensing circuit, protect against over temperature.
Has excellent soft start for suppresses unpleasant switch on noise, the power ON/OFF controlled by main power switch and also available by remote control terminal on the rear panel.
FEATURES
- Inputs are balanced XLR jacks and screw type connectors
- Through link male XLR jack for daisy-chain Input system
- Adjustable gain control by semi fixed controlled attenuator
- 400Hz High pass filter for reduces internal resonances and more increases sound quality
- Speed control Fan cooling
- Logical LED meters are present for power in/output level for -20, -10,0,and Clipping
- Built-in High Fidelity 100V audio transformer
- Available power on and off by remote control switch terminal
- Two way Mains power for DC 24V or AC 110V-240V
