later, following the XS-01, the new XS-02 uses the software functional architecture of FA1 , 2.0-inch large screen; the main chip dual core maximum running frequency 580Mhz, supports DSD 256 hard solutions. Equipped with independent audio dual crystal + two AK4490EQDAC chip + Texas Instruments imported amp chip TPA6120A2+ exchangeable op amp design, lossless format, support for Apple format, PCM up to 32bit, FLAC, ape 0~8 level support, positive and negative 8.2V high voltage Headphone Amp and replaceable amplifier design.
The original OLED was modified to a 2.0 inch high-definition screen; (more information is displayed)
The original single AK4490EQ DAC was modified to a dual AK4490EQ architecture; (Reducing the volume of sound information and stereo separation, the sound field will be better)
The original single-core IIS processing chip was modified to dual-core 580MHZ high-end master chip; (sub-core interface, operation processing; main core decoding IIS output, more efficient)
Added Apple Lossless Audio Format to Audio Format – M4A, AAC, OGG; DSD, DSF & DFF up to support DSD256; APE, FLAC 0 ~ 8 level compression ratio support;
The positive and negative power supply is optimized to 8.2V, op amps can choose more; (Original with OPA604AP is also very strong, friends without DIY interest need not be replaced)
USB supports direct copy music, no need to use a card reader;
Simple installation and demolition, operational amplifiers can be swapped, everyone can MOD;
Added automatic shutdown, sleep shutdown, favorites, EQ (Recommended HiFi mode), fast forward mode support, return key customization (Long press off screen change or long press to return to the main menu), support folder cycle, onboard Mode, multi-level directory and 9999 music management, etc...
Continuous playback for 8 hours, comprehensive test; (actual test 16bit wav screen off 10 hours +)
Can customize the logo on back of the shell; (laser engraving)
Low_LO: LO output, suitable for audio sources (connected to amplifier or car),and no lock level, can be connected to low impedance headphones within 64Ohm.
High_AMP: TPA6120A2 Headphone Amp output, suitable for driving high impedance.
Note: The above is only recommended for use. It should be connected according to the sensitivity or impedance of the earphone.
Dual AK4490EQ architecture; (will be more outstanding on recovering sound information volume and stereo separation)
Exchangeable operational amplifier design;
8-hour continuous playback;
TPA6120A2 AMP chip;
Full hard decode design;
Size: 9.3cm (L) x 5.8cm (W) x 2cm (H)
