The Crestron® AMP-4600 amplifier is designed to complement the Crestron Avia™ family of digital signal processors, and is well-suited for all types of commercial audio applications. The AMP-4600 furnishes four channels of clean, efficient amplification in a space-saving 1 RU rack-mountable chassis. Each channel is configurable for Lo-Z or Hi-Z operation, as well as stereo and bridged modes. Network connectivity enables configuration, monitoring, and control via the Avia Audio Tool software, a Crestron control system, Crestron XiO Cloud™ service, or Crestron Fusion® software.

Solid and Efficient Performance

The AMP-4600 is engineered to deliver exceptional performance and reliability with low distortion, low noise, and high power headroom. Advanced Class D technology maximizes efficiency to reduce power consumption and heat dissipation. An internal universal power supply with power factor correction ensures consistent performance with varying line voltages.

The AMP-4600 features professional balanced inputs that support input signal levels up to +24 dBu. Rear panel input attenuation controls allow for signal level matching. Remote level control and monitoring is enabled using the Avia Audio Tool software, or using a touch screen control panel or mobile device through integration with a Crestron control system. Integration with a control system also enables centralized monitoring and control of multiple amplifiers throughout a facility as part of a Crestron Fusion or Crestron XiO Cloud managed enterprise.
