The amplifier provides analog and digital inputs, network monitoring and control, programmable General Purpose Input/Output (GPIO) ports, and on-board Digital Signal Processing (DSP). The amplifier also meets EN 54-16 compliance for life safety systems to serve the needs of hospitality, large venues, and other markets.
It is compatible with Harman’s BLU Link digital audio transport and accepts digital inputs via its rear-panel RJ-45 connectors. This digital control allows for networked monitoring, recallable presets, and the setup of secondary inputs that engage if the primary inputs fail. The built-in DSP capabilities include limiting, input/output EQs, delay, and a matrix mixer.
Each channel pair can be bridged for powering higher power applications such as a subwoofer. The 4|600N also has channel-independent high- or low-impedance output that is selectable from the rear-panel DIP switches. This allows you to integrate the amplifier into a variety of different setups. Each of its 4 channels additionally features independent attenuators with a range from 0 to -80 dB.
The front panel of the 4|600N provides a series of system indicators, including level and signal, ready, clip, thermal, and fault alerts for quick visual monitoring of the system. The unit can be integrated into a control system for powering on and off as well as engaging its sleep mode for saving energy when not in use.
