Chi-Fi Excellence 1 Year ofWarranty Ideal forAudiophiles Ideal forIndoor Use For Studio &Professionals Connect WithRCA 2x 2800mW @ 32ΩPower Output VolumeControls DESCRIPTION FEATURING THE NEW NFCA CIRCUIT FOR NOISE-FREE, HI-RES AUDIO The Topping L50 features the latest redesigned NFCA circuit based on the working principle of the A30 Pro. The NFCA circuit provides 2 times the power compared to the previous generation of the circuit. This circuit also has an ultra-low noise floor of 0.3uV and offers an excellent dynamic range. These features enable the L50 to transmit audio at Hi-Res quality. THREE-LEVEL GAIN SWITCH TO POWER HEADPHONES WITH VARYING IMPEDANCE The Topping L50 is capable of powering various headphones with high impedance. The device offers high output voltage with 3500mW of power, sufficient to drive the most power demanding headphones while delivering less than 0.1 Ohms of output impedance with negligible levels of background noise. L50 also features a three-level gain switch allowing you to tune it according to the requirement of the connected headphones. L50 covers a wide gain range, which is sufficient to meet the needs of low-sensitivity full-sized over-ears to high-sensitivity IEMs. L50 is perfectly suitable to power many headphones. INPUT PASS-THROUGH FUNCTIONALITY FOR SPEAKERS AND MONITORS Topping L50 offers a well thought out input pass-through functionality. Input pass through functionality comes in handy when using the device with active monitor speakers. What this function does is, it bypasses the input signal and it is directly routed to output to the RCA or TRS pass-through ports without the need for amplification. It works even when the L50 is turned off, without the amplification capabilities. EQUIPPED WITH SINGLE-ENDED AND BALANCED INPUT AND OUTPUT CONNECTIONS Topping L50 offers both single-ended as well as balanced input/output options. You can pair the L50 with the latest E50 Desktop DAC and use the TRS balanced or RCA single-ended input/output function, it also has input pass through RCA and TRS ports. For headphones, the L50 has a 4-pin XLR balanced and 6.35mm single-ended ports.
