Description LittleDot MK-8SE Fully Balanced Pure Vacuum Tube Amplifier Wide Dynamic Range High Performance Headphone AmplifierDescription:- The MK-8SE is a pure vacuum tube fully balanced/unbalanced compatible headphone amplifier, characterized by high signal-to-noise ratio and large dynamic range (undistorted output swing up to 60Vpp at 300 ohms). The input stage uses a dual transistor 12AT7, and the final output stage uses a low internal resistance/high linearity Russian military dual transistor 6H30PI, which obtains sufficient output power. By changing the GAIN switch of the entire machine, different impedance can be simultaneously considered Requirements for headphones with different sensitivities. This machine adopts an OCL circuit structure without output capacitors, and uses high-voltage OP as the midpoint servo control, which not only improves the low-frequency control force but also ensures the stability of the circuit. This machine also has a midpoint offset protection circuit, further improving the reliability of the entire machine.- The balanced input and output sockets of this machine are equipped with XLR sockets with locking for NIUTRIK, ensuring good electrical contact and durability. The volume control of this machine adopts for ALPS potentiometer; The resistance of key parts adopts for DALE precision resistance; The capacitor adopts well-known brands for WIMA/ERO/CHEMI-COM. The MK-8SE, which adopts a fully balanced OCL circuit, has a good sound field, rich high-frequency details, faithful mid frequency restoration, stable low-frequency control, and a very clear sense of hierarchy. In addition, it can be used not only to drive headphones, but also as a fully balanced vacuum tube preamplifier to drive a post amplifier with balanced input.Specification:- Input: XLR 3p x 2; RCA x 2- Output: XLR 4p x 1 (headphone output); 6.35 x 1; XLR 3p x 2 (headphone output or pre-amp output)- Distortion: 0.01% (output: 2Vrms 1000Hz); 0.03% (output: 10V rms 1000Hz); 0.2% (output: 20V rms 1000Hz)- SNR: 96dB- Frequency response: 5Hz – 80KHz (-3dB); 10Hz – 30KHz (-1dB)- Output power: 2W (600ohms); 1W (300ohms)- Magnification: GAIN = HIGH : 6 GAIN = LOW : 3- Power consumption: 110VA- Product size: 350 x 290 x 140mm- Product weight: 9.6kgPackage Included:- 1 x HostPayment Terms 1.
