Know before you buy
The LNI-2 acts as a power conditioner for 12V devices. It uses galvanic isolation and an active filter to strip away electrical noise, hum, and interference from your power supply, resulting in a cleaner, more stable signal for your audio gear.
The LNI-2 accepts an input voltage range of 9V to 18V DC. As long as your power source falls within that range, the unit will regulate and output a clean, fixed 12.0V at up to 2A.
The optional ground terminal provides flexibility for complex setups where you may need to manually resolve ground loops or specific grounding issues. In most standard setups, you may not need it, but it is there if your system requires a dedicated chassis ground.
The device features integrated status LEDs on the front panel. These provide immediate visual confirmation of your voltage status and will alert you if the unit detects an overload condition.
Yes, it is specifically engineered for high-fidelity applications. By utilizing an Ultra Low Noise linear regulator and galvanic isolation, it is designed to protect sensitive audio components from the noise typically introduced by standard switching power supplies.
The unit features a lockable output socket to ensure a secure connection. It comes with a dedicated DC sensor connection cable to ensure precise voltage delivery to your equipment.
