Product Description

Improved NFCA

L30 II uses redesigned NFCA (Nested Feedback Composite Amplifier) module. It provides 2x output power at 3009 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%.

3500mW x2@16Ω 2700mW x2@32Ω 2000mW x2@64Ω 560mW x2 @300Ω

Output Voltage:37Vpp Output Peak Current:1400mA Output Impedance<0.1Ω Best combo for active speakers

We also recommend that L3011 and E301I be used with active speakers.

Connect the two outputs of L3011 to headphones and active speakers. By switching the outputs of L30II, you can enjoy music on headphones and active speakers respectively,

Compatible with almost all kinds of headphones Different headphones can be easily driven by the L30 II

L30 II’s output has high output voltage, high current, low output impedance, so no headphones that can’t be dealt with.

High output voltage can easily drive high impedance headphones; High output current allows low-sensitivity headphones to obtain enough power;The low output impedance will not bring unnecessary effect on FR when driving low-impedance headphones.

Three gain settings to suit different needs

L30 II 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-sensitity 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.

Interface specification:

1 Output switch: Switch to PRE output(RCA output) or HPA output(Headphone output), or turn off.

2 Gain switch: H/ MI L respectively corresponds to 16.5dB / 0dB / -14dB
