Core Features & Applications
Dual Ultra-linear Preamps
Features two Combo input interfaces supporting microphone, instrument, and line signals. With an Ultra-low Equivalent Input Noise (EIN) of -130.5dBu, it precisely captures the dynamic details of vocals and instruments against a pitch-black background, reproducing the most authentic sound.
NFCA-LE Flagship Amp Technology
Built with audiophile-grade NFCA-LE amplifier circuitry, it provides an astonishing 580mW of power and perfectly drives professional headphones up to 600Ω. Ultra-low distortion (THD+N < 0.0001%) and a 1uVrms noise floor ensure accurate, uncolored monitoring.
Flexible Output Expansion
In addition to standard TRS balanced monitor outputs, it offers an extra 3.5mm AUX output for connecting consumer speakers, and an Optical SPDIF output for connecting to high-end DACs, adapting to various monitoring and playback needs.
