Wimlim W520B QCC5125 Bluetooth Lossless HiFi Headphone Amplifier PCM1794 USB Decoder 5532 Triple Op Amp
Features:
- The use of PCM1794 decoder chip, 5532 triple op-amp dual power boost circuit architecture, built-in 6120 earphone amplifier chip, easy to promote high-resistance headphones.
- Power supply using Type-C interface, internal isolation with drying processing, the use of Nichicon filter capacitors, so that the system noise will be lower.
- The programme sound quality through the full, low-frequency Q bullet mid-frequency full, high-frequency delicate dynamic range, these are not only the PCM1794 24-bit king chip given, but also the results of the circuit programme optimization, recommended for high-end audio systems/headset HIFI headphones.
- The use of visual transparent skylight (default does not paste, easy to replace the op-amp) stylish and stable, so you love it.
- Adopt system volume adjustment programme, encoder/remote control mobile phone/computer volume bar to reduce interference and distortion, improve fidelity, better than analogue potentiometer, there will be no left or right channel bias sound problem.
- W520B adopts the system volume control its purpose is to eliminate the analogue volume, digital volume adjustment process generated by the loss of audio signals and distortion, is to improve the fidelity of a solution, the number of segments of the volume control by the mobile phone or computer system volume segments to determine.

Precaution:
- This decoder converts USB audio signals into analog audio signals and inputs them to HIFI amplifiers/WIFI headphones for use. To ensure ideal sound quality, please try to avoid inputting them to active speakers and refer to the following suggestions.
- The decoder output belongs to high fidelity analog signals. After connecting to the preamplifier/power amplifier, please do not adjust the high and low frequencies to avoid losing high audio fidelity signals and deteriorating sound quality.
- Do not use EQ and other sound effects settings in mobile/computer playback software, as this will directly affect the restoration of high fidelity analog signals.
- It is strongly recommended to use a computer as the front-end playback device and install the fooobar2000 software. After successful installation, set the source code push output mode. Specific tutorials can be found on the website.
- Recommended mobile playback player for HiBy Music, with exclusive settings. Specific tutorials can be found on the website.
Package Included:
- 1 x Decoder
Note:
- Be sure to set exclusive/push settings, as the computer or mobile system will resample the audio signal, which can have a serious impact on sound quality. After setting exclusive/source code push, it will no longer be affected by the system. At this time, the sound heard will no longer be muffled, and the high-frequency details will be rich and clear. The spatial position of the vocal instrument will be better, and the stereo sound image will be better. Highly recommended.
