TOPPING L30 IINFCA Headphone Amplifier Preamplifier BlackTopping unveils its L30 II, evolution of the very good L30 headphone amplifier and preamplifier. This new version is based on the architecture of the first model, while bringing many improvements to optimize the performance of the device and its sound reproduction. Improved NFCAThe Topping L30 II uses a revised NFCA (Nested Feedback Composite Amplifier) amplifier module. This one allows notably to double the output power available under 300, compared to the L30. An output power offering the possibility to the L30 II to accompany the vast majority of headphones on the market, including the most demanding models with a high impedance. The new circuit also offers an ultra-low noise level measured at 0.3V, a dynamic page of 144dB as well as a THD+N of 0.00006%. Gain settingIn order to allow the L30 II to accompany both high-impedance headphones and very sensitive in-ear monitors, the amplifier offers a three-level gain control: -14dB, 0dB and 16.5dB. 1Output selector2Gain selector3Power indicator4Jack 6.35mm headphone output5Volume button6Right channel RCA input7Left channel RCA input8Right channel RCA output9Left channel RCA output10Power connectorTechnical characteristicsSPECIFICATIONSProduct typeHeadphone amplifier and preamplifierAmplification moduleNFCAInput1x Stereo RCAOutputs1x Stereo RCA1x Jack 6.35mm headphone outoutHEADPHONE AMPLIFIER MEASUREMENTSTHD+N @ 1kHz, A-Weighting 0.00006% @ 500mW, 32Ω 0.00005% @ 80mW, 300ΩTHD @ 90kBw, 20Hz-20kHz 0.00008% @ 500mW, 32Ω 0.00007% @ 80mW, 300ΩSNR @ Max Out, 1kHz, A-Weighting144dBDynamic range @ 1kHz, A-Weighting144dBFrequency response20Hz-40kHz (0.05dB)Output level14Vpp @ G=L31Vpp @ G=M37Vpp @ G=HNoise level 0.3Vrms @ G=L 0.3Vrms @ G=M 1.4Vrms @ G=HCrosstalk @ 1kHz-92dBInput sensitivity25Vrms @ G=L11.2Vrms @ G=M2.0Vrms @ G=HGain-14dB @ G=L0dB @ G=M16.5dB @ G=HOutput impedance 0.1ΩOutput power2x3500mW @ 16Ω, THD+N0.1%2x2700mW @ 32Ω, THD+N0.1%2x2000mW @ 64Ω, THD+N0.1%2x560mW @ 300Ω, THD+N0.1%Load impedance 8ΩPREAMPLIFIER MEASUREMENTSTHD+N @ 1kHz, A-Weighting 0.00006%THD @ 90kBw, 20Hz-20kHz 0.00007%SNR @ Max Out, 1kHz, A-Weighting144dBDynamic range@ 1kHz, A-Weighting144dBFrequency response20Hz-40kHz (0.05dB)Output level14Vpp @ G=L31Vpp @ G=M37Vpp @ G=HNoise level 0.3Vrms @ G=L 0.3Vrms @ G=M 1.4Vrms @ G=HCrosstalk @ 1kHz-92dBInput sensitivity25Vrms @ G=L11.2Vrms @ G=M2.0Vrms @ G=HGain-14dB @ G=L0dB @ G=M16.5dB @ G=HOutput impedance20ΩGENERALDimensions100 x 135 x 32mmColorBlackPackage1x Topping L30 II1x Power adapter1x Male Jack 6.35mm to Female Jack 3.5mm adapter
