Precise Base Time:
- N19 has a built-in HiFi OCXO, which provides accurate clock signals for the whole machine. And through the intervention of 10M clock signals, the clarity and transparency of the sound have been greatly improved, and the sound field is wide and the positioning is accurate.

External 10MHz Clock:
- The N19 provides one-way clock input for easy connection to your high-quality clock to improve machine performance. When a valid clock is entered, the built-in OCXO thermostat will automatically power off to reduce interference.

Femtosecond Clock:
- The N19 has a SI5340 professional-grade clock synthesizer. Output jitter is as low as 90fs in the femtosecond range, providing high-quality clock signals for the whole machine. The clock performance is far better than that of other switches using PS-level ordinary clock chips.

Dual-core Filtering:
- Its effect is far better than that of ordinary single-chip switches, thanks to unique filter loop connection, architecture isolation, complete differential mode signal transmission, impedance matching, waveform repair, signal clutter suppression and high-quality clock signal synchronization. Sound performance: fast speed, high resolution, and strong driving force. The sound is crisp and delicate.

Supports SFP Photoelectric Conversion Module:
- The SFP interface can connect two switches to achieve optical isolation and eliminate all clutter interference on the Internet, which makes the sound cleaner.

LT3042+PNP Primary Voltage Regulator:
- Three LT3042+PNP form a first-stage voltage regulator, respectively, supplying power to switch chip, ultra-low jitter clock chip and OCXO thermostat clock. Based on 4-layer PCB board and independent power supply circuit and complete ground plane isolation, it eliminates mutual interference between components, greatly improves power quality, and make the sound clean and crisp.

Multi-channel Voltage Regulator:
- Thanks to the 7-stage secondary regulated power supply, the voltage is regulated in graded groups to eliminate interference.

Transformer with Sealed Design and Metal Shielding:
- With sealed design and metal shielding layer, the 30W audiophile transformer can effectively isolate the electrical, magnetic field and vibration interference, so that the sound is clean.
