• Power levels matched to the most popular loudspeakers and optimized for maximum real-world headroom into 4-ohm and 8-ohm speaker systems

• Class-D output stage with a universal power supply for high performance and efficiency

• Extensive built-in loudspeaker processing, includes high & low-pass filters, 4-band PEQ, limiting, and delay

• Large LCD display simplifies amplifier setup and indicates amp status

• Inputs: Parallel XLR and 1/4” TRS connectors for compatibility with any source while providing convenient loop-thru capability

• Precision rotary encoders for gain and DSP parameter control

• Outputs: Professional binding post and NL4 connectors (compatible with NL2) provide for mono and bi-amp speaker connections

• Digital Limiting automatically protects the amplifier from damage due to temperature rise or overdrive

• Adjustable speaker protection to match your loudspeaker’s power and impedance

• Front panel LEDs indicate signal presence, input overload, and amplifier clipping
