The E30 II Lite uses a convenient 5V DC power supply. This means it can be used almost anywhere and can be connected to a computer, phone charger or power bank. A built-in protection circuit protects the E30 II Lite and will display an error message in the event of an incorrect power supply.
To address the noise problem that a 5V supply can cause, the E30 II Lite includes a discrete LNRD (Low Noise Reference Driver) circuit. It filters out noise from the power supply to provide the audio circuits with an ultra-low noise, perfectly stable electrical signal. As a result, the background noise of the E30 II Lite is less than 1.9 μV.
