GP-250
250W mono channel, class-D / high power amplifier for subwoofer

GP-250, a 250-watt plate type power amplifier of mono channel, is created for integration with subwoofer speaker for optimum bass / ultra-low sound effect performance in an audio system.

The GP-250 adopts high efficiency switching mode power supply for driving speaker through its digital / class-D amplifier, ultimately allows compact size and low weight for not just itself but also the integrated speaker system.

 

 

 

This amplifier is designed to be eco-friendly.
Power on/off can be automatically managed by the audio signal

(from the source); When the system is totally in idle for certain minutes, the power-saving circuit will turn this amplifier into deep sleep, with tiny standby consumption of less than 0.5w. In certain applications which will need the amplifier keeps awake all the time, the “sleep mode” by audio-signal can be defeated with the on-panel switch.

feature highlight

- 250 watts, mono channel
- class-D digital format
- switching power supply
- phase selection
- defeatable audio-trigger
- low standby power (< 0.5w)
.
On the panel there are 2 rotary controls for volume and crossover frequency refinement, so user may fine tune the subwoofer’s response to get the optimum system acoustic result The GP-250 is equipped with RCA jacks (the most commonly-used connector) for connecting to all kind of audio source machines.
