- Low Distortion, High Performance
- L30II+E30II=Perfect Companion
Improved NFCA
L30 II uses redesigned NFCA (Nested Feedback Composite Amplifier) module. It provides 2x output power at 300Ω load compared to L30. The new circuit has 0.3uV ultra low noise and 144dB dynamic range as well as 0.00006% THD+N.
Sound quality is never a problem
With the help of NFCA, L30 II easily reach the top of the industry,and it has almost perfect performance regardless of distortion, dynamic range,and multi-tone testing.
Low distortion while outputting high power
The L30II can maintain ultra-low distortion output under high power load. Under 32 ohm load and 2500mW output,the THD+N is lower than 0.00008%; under 300 ohm load and 300mW output,the THD+N is lower than 0.00007%.
Three gain settings to suit different needs
L30 ll has three gain options:-14dB,0dB,16.5dB.Improved gain settings can cover a wider range of needs to meet the needs of different headphones from low-sensitivity full-sized over-ears to high-sensitivity IEMs.With the help of extremely low noise 0.3uV,even IEMs will not hear any background noise.
L30II+E30II=Perfect Companion
It is usually recommended to use L30II with E30II together to achieve the best results. These two can make a perfect match, or even better with active speakers. Simply connect the L30II to headphones and active speaker, by switching the outputs on L30II, you are able to easily enjoy music on headphones and active speakers respectively.
