Norse X1 Power Amplifier

X1 Power Amplifier

The X1 Power Amplifier is the heart of the Norse system, delivering unmatched versatility. A rear-panel toggle switch lets you effortlessly switch between stereo and mono modes, making it easy to start with a single stereo amplifier and upgrade to a dual-mono setup.

The X1 also features an adjustable bias toggle with two modes:

• Normal Bias: Increases Class A operation for a warmer, richer sound with exceptional linearity
• Low Bias: Prioritizes efficiency while maintaining high-quality audio, ideal for extended use or less demanding applications.

Simpler is better

X1 uses a single voltage amplifier stage for the shortest signal path possible. It employs a fully balanced design without ground reference, paired with a high-performance DC servo operating outside the signal path. The input stage features hand-matched, current-loaded JFETs in a foldback cascade arrangement, ensuring linear performance at any output level. Combined with current feedback technology, the X1 delivers fast, stable, and dynamic sound.

X1 Specifications:

• Stereo Mode:
• 50W per channel @ 8 Ohms
• 100W per channel @ 4 Ohms
• Mono Mode:
• 200W @ 8 Ohms
• 390W @ 4 Ohms

This robust power output drives a wide range of loudspeakers, from compact bookshelf models to demanding floorstanders, with precision and control.
