A-414
| Description - Based on PowerPhysics proprietary One Cycle Sound™ PWM control method, the A-414 provides 400 Watts of audio power into 4 ohm speakers before clipping and 500 Watts at 1% distortion. The A-414 amplifier has temperature and current monitoring outputs ideally suited for off board analysis in our DSP series of preamplifiers. Its full or "H " bridge output stage is thoroughly protected against any type of output short or speaker fault to provide robust, long term operation. The A-414 accepts a bus voltage up to 85 Volts for high peak power. Like all of PowerPhysics A-series amplifiers, the A-414 is very efficient and a high bus voltage does not force the use of large heat sinks or fans. Musical transients have the headroom they need and unused power is not converted into heat. |
