- Switching power technology digital power amplifier
- Class-D PA power amplifier of minimum power consumption
- 1RU height for less rack space and less heat generation
- Four channel power amplifier into 19” rack mount unit
- Rated power output at 4x120W
- Four channel separate speaker outputs 8Ω/100V
- Balanced line input by phoenix connector for four channels
- Each input with separate gain control.
- Each four channel with high-cut filter.
- Built-in auto standby feature to save power consumption
- Separate four channel indicators for protection, clip, input and output
- Complete short circuit, overload, high temp, clip and DC protection
- Wide AC input switchable between 115V and 230V
- With 24V DC input.
- The DA range digital class-D power amplifier is of switching power technology, which features of minimum power
- consumption and much higher efficiency up to 85%, moreover it helps to save installation rack space, generate less heat
- so as to extend its performance life span as a result.
- The DA-4120 is of rated power output at 4×120W, so it could be used as four zone multiple sources public address
- system at minimum cost. The versatile loudspeaker outputs of both high impedance 100V & low impedance 8ohms
- enable it meet both PA fixed installation and Hi-fi stereo sound installation jobs.
- There are four balanced inputs by phoenix connector for each channel with gain control. Four separate zone speaker
- outputs both by 100V & 8ohms. The built-in four channel separate high-pass filters could be enabled or disabled through
- the dip switch pre-setting.
- Automatic standby enable after no detection of signal input for one minute, immediately wake up at sight of any input.
- Visual working status indicators include protection, clip, input and output for easy supervision. With complete short
- circuit, overload, high temp, clip and DC protection.
- Switchable AC power supply from 115V to 230V, thus it support worldwide sound system installation. DC24V operation is included.
