Sublimely simple operation
The front panel controls and indicators provide your system's vital signs at a glance. After pressing the Power button, the Power LED lights to show the amp is ready for action. All channels feature positive-detent Gain controls with Signal LEDs that light when a signal is present, as well as Clip LEDs to indicate when the signal is distorted and you need to reduce the input signal.
The rear panel is just as elegant, with combo XLR and 1/4" TRS input connectors making the NU4-6000 compatible with virtually any source, balanced or unbalanced. Professional twist-lock speaker sockets are provided to ensure every drop of output power gets to your loudspeakers. The rear panel is also where you'll find the switches that enable the NU4-6000 to work in quad mono, dual stereo, or dual mono bridge mode. A built-in crossover switch enables the amp to operate in biamp mode, sending low frequency content to passive subwoofers, while the high frequency output is channeled to full range loudspeakers.
