Precise base time
N19 has an audiophile-grade built-in OCXO. It provides accurate clock signals for the entire machine. Through the intervention of the 10M clock signal, the clarity and transparency of the sound have been greatly improved, and the sound field is wide and the positioning is accurate.

An external 10MHz clock can be connected
N19 provides a clock input for easy connection to your high-quality clock to improve N19's performance. When a valid clock is input, the built-in OCXO will automatically power off to reduce interference.

Femtosecond grade clock
It has a clock chip with an output jitter as low as 90fs, providing high-quality clock signals for the whole machine. Its clock performance is much better than that of PS-level ordinary clock chips used in other switches.

Dual-machine dual-core filtering
Dual-core and dual-machine design, unique filter loop connection, architecture isolation, complete differential mode signal transmission, impedance matching, waveform repair and signal clutter suppression. With high-quality clock signal synchronization, its effect is far better than that of ordinary single-chip switches. The sound is fast, high-resolution, driven, crisp and delicate.

Supports SFP photoelectric conversion module
Through the SFP interface, it can connect two switches to achieve optical isolation. It can eliminate all clutter interference from the Internet, making the sound cleaner and clearer.

LT3042+PNP level 1 regulator
Three-way LT3042+PNP form a level 1 voltage regulator to supply power to switch chip, ultra-low jitter clock chip and OCXO clock. Based on the 4-layer PCB board, it realizes an independent power supply loop and complete ground plane isolation, eliminates mutual interference between components, greatly improves the power supply quality, and makes the sound clean and crisp.

Multi-way regulation
Up to 7 levels of two-stage regulated power supply and hierarchical group voltage stabilization eliminate interference.

Sealed transformer with a metal shield
The 30W audiophile transformer can effectively isolate electrical, magnetic field and vibration interference, making the sound clean.
