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 & 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.
Configurable & Controllable
The AMP-4600 delivers 600 watts per channel into 4 or 8 ohm “Lo-Z” loads. Each channel is individually configurable via software for use with “Hi-Z” distributed speaker systems (either 70V or 100V). Adjacent pairs of channels may be configured for stereo or bridged operation. Stereo mode enables remote control of a stereo pair of speakers using a single set of controls. Bridged mode allows two channels to be combined to provide a single channel delivering up to 1200 watts into 8 ohms.
Each output channel can be independently configured to throttle the amount of power delivered to connected loudspeakers. Power throttling can be used to protect connected loudspeakers from receiving too much power.
The power throttle can also be used for output load balancing. This is useful when mixing different loudspeaker types on adjacent channels such as a subwoofer that requires continuously high power versus a high frequency compression driver with a much lower power requirement. Using Power throttle, the output of the amplifier is provisioned to match the loudspeaker and line drive requirements. Amplifier gain is automatically adjusted such that a 0dBu input will yield the selected power throttle output level. No matter the gain from head-end equipment feeding the amplifier, power throttle will consistently provide an extra level of loudspeaker protection and overall system optimization.
The AMP-4600 features comprehensive protection against overheating, shorted or overloaded speaker lines, excessive signal levels, and other faults. Each channel is independently protected, allowing an individual channel to enter protection mode without interrupting the operation of other channels. Protection is automatic, quickly disconnecting the speaker line and shutting down the affected channel, and then restoring normal operation once the fault is resolved. Clear indication of any fault is provided on the front panel, and may also be reported to a control system to provide notification on a touch screen or mobile device, through a text message or e-mail, or at a central help desk using Crestron Fusion software or the Crestron XiO Cloud service.
