Matrix Audio NA-1 Headphone Amplifier

Yes, the NA-1 is designed to handle demanding loads. Its balanced output delivers up to 4.5W at 300Ω and 2.3W at 600Ω, ensuring high-impedance headphones receive sufficient power and control.

The unit offers three output configurations to accommodate most cables: a standard 6.35mm single-ended jack, a 4.4mm balanced output, and a 4-pin XLR balanced output.

Absolutely. The NA-1 features both XLR and RCA pre-outputs, allowing you to connect it directly to active speakers or a dedicated power amplifier. It also includes independent gain control to match the sensitivity of your specific speaker setup.

The NA-1 uses a pure Class A circuit, which naturally generates heat. However, its vertically layered PCB architecture is specifically engineered to optimize thermal management and internal isolation, ensuring stable performance during extended listening sessions.

The NA-1 uses a high-quality ALPS motor-driven potentiometer for volume control. You can adjust it manually via the front panel knob or use the included IR remote for precise, remote-controlled adjustments.

The independent dual-gain control allows you to optimize the signal level separately for your headphones and your preamp outputs. This ensures you can achieve the ideal volume range and signal-to-noise ratio regardless of whether you are using sensitive IEMs or power-hungry full-sized headphones.
