blushPA3S+ upgrade version: 1: Upgrade interface 2.5MM/3.5MM stereo/3.5MM balanced/4.4MM compatible with general balanced stereo headset plugs on the market. 2: Optimizing the power of the power supply still adopts a separate set of ±13V power supply to improve the separation dynamics. 3: The op amp can be directly replaced to satisfy the user's DIY. The 3U thickened gold-plated op amp seat has better contact durability and durability. 4: Increase the built-in BASS low-frequency enhancement switch. 5: Optimize the high gain gear multiples for driving high impedance or low sensitivity headphones. 6: Adopt a customized composite dual op amp as the pre-amplifier to process the sound (left and right independent group) 7: Optimize anti-interference design. 8: The headphone driver uses two Class-AB ultra-low distortion 0.00014% high current TPA6120A2 outputs. 9: Support stereo 3.5MM input balance/stereo output, 2.5MM balanced input balance/stereo output is extremely playable. N=NORMAL (stereoscopic) B=BALANCED (balance) When replacing the op amp or adjusting the low frequency enhancement switch of the amp, please pay attention to the bottom grounding shield push rod and push the main board into the casing (shutdown operation)...
1: 3.5MM stereo output interface is compatible with three single-ended or four balanced headphones. 2: The 3.5MM/PRO balanced output interface only supports four balanced headphones (3.5Mm stereo headphones cannot be used or the amp components may be damaged). 3: 4.4MM balanced output interface. 4: 2.5MM balanced output interface. 5: Power indicator (green normal power and low red power). 6: Four-channel volume control knob. 7: Input signal button selection (B-2.5MM balanced input when popped up, N-3.5MM stereo input when pressed). 8: Adjust the gain of L channel. 9: Adjust the gain of R channel. 10: 2.5MM balanced input interface. 11: 3.5MM stereo input interface. 12: 8.4v charging interface (must be equipped with a charger with charging function). 13: Power switch.

Accessories: USB to 8.4V charging cable (used with USB 5V 2A or more charging head) bundled with two large and two small, optional recording cable, 4 small gold standard stickers, small hexagon wrench.,Warranty scope: The whole machine is guaranteed for 1 year (batteries are wearable parts). Parts are charged for man-made damage, and the whole machine is maintained for life. Precautions: 1: If connecting to a desktop or equipment that needs to be grounded, it can be taken at the 3.5MM input interface. 2: It must be shut down when disassembling and transporting the amplifier. When installing the motherboard, pay attention to press the bottom grounding rod before pushing the motherboard. 3: Do not use a balanced to three-dimensional adapter or adapter cable may cause short-circuit damage to the internal amp.
