SpacEND ONE Integrated decoder, front stage and dynamic headphone amplifier an instruction manual
Design Introduction
SpacEND ONE The decoding, front stage and dynamic headphone amplifier all-in-one machine adopts a fully balanced line, the volume adjustment adopts a Japanese quadruplex electric remote control potentiometer, the digital input USB interface adopts a customized XING audio studio dedicated USB interface, the windows system needs to install driver software (see the U disk in the manual for details), the digital decoding adopts two PCM1794 chips (supporting 24Bit/192k), the decoding output adopts a fully balanced design, and the analog line voltage amplification adopts LME49720 LME49724, OPA1612, eight COMS operational amplifiers OPA1678 introduced in 2021 are used for output to drive the customized high and low impedance permalloy output transformer. The whole machine is designed in an integrated way to balance the front output function. The chassis is of all aluminum design, and the main transformers are all epoxy resin filled Talema transformers in Britain to ensure that the vibration of the whole machine is controlled within the minimum range The main power supply is designed with two latest "ideal" power modules LT4320 to drive eight high-power COMS tubes to achieve high efficiency AC to DC conversion. CLC filtering circuit with choke is introduced to improve the signal noise of the whole machine, plus secondary LT317, LT337 full line voltage stabilizing circuit. Nijikang fever capacitor is used as the electrolytic capacitor to ensure the power supply of pure, highspeed and energetic amplifier
