Sensitivity input: 280mV; 520mV (pre-input). Harmonic distortion: 1% (1kHz) Machine frequency: 15Hz 30kHz (-1.5dB). Net weight: 22.5kg (Hifi exquis 1101017). Power consumption: 260W (Hifi exquis 1101017).
Pipe preamplifier: 12AX7 × 1 (Equivalant ECC83, CV4004 ECC803,5751). Pipe preamplifier: 12AU7 × 2 (Equivalant ECC82,5814,6189 CV4003). Tube force: KT88 × 4 (Equivalant 6550). Rectifier: 5AR4 × 1 (Equivalant GZ34) (Hifi exquis 1101017).
Dimension :(W × D × H): 410mm x 335mm x 198mm (Hifi exquis 1101017). Power supply voltage: 110-120v 220-240v ± 5% (50 / 60Hz). Working conditions: Temperature: 0 ° C 40 ° CHumidity: 20% to 80%. Storage conditions: Temperature: -20 ° C 70 ° C Humidity: 20% to 90%. Handmade, using scaffolding welding (Hifi exquis 1101017).Using both high quality and wide frequency response EI transformer output. Using custom Z11 core torque transformer (Hifi exquis 1101017). Amplification and smooth drive use SAR4 rectifier. Using 2X12AX7 and 2X12AU7 as amplifiaction. Special use high selected KT88 tube as push pull power amplifier lamp, providing triode switch and especially connnection linear connection modes. The triode connection mode is more suitable for the sound and the sound is softer, delicat as well as nature. The ultra-linear connection is suitable for large scence, the sound is more open and full of life. It has pure power ans amplifier that can conncet with independent pre-amp of input signal. It has a phono phase input function, which can be connected directly with MM vinyl turntables. There is a current tube power and electric button control dial dial.
Infrared Function Remote Control (Hifi exquis 1101017). Selection of Japanese high-grade Alps engine potentiometer. Easy installation of vacuum-type plug-in protective hose (Hifi exquis 1101017).
