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.

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.

Power Throttling

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 or for output load balancing, useful when mixing different loudspeaker types on adjacent channels. Amplifier gain is automatically adjusted such that a 0dBu input will yield the selected power throttle output level, providing extra loudspeaker protection and overall system optimization.

Fully Protected

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.
