Nobsound P10 Headphone 30V Boost Equipped with Interchangeable 1100mW Dual Compact Headphone Amplifier Amplifier, Circuit, Op-Amp, Output,

---------------------------------------------------------------------- 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ----------------------------------------------------------------------

Wide Range of Headphone Drive Performance: Dedicated headphone amplifier circuitry delivers 1100mW output power into a 32Ω load. Supporting an impedance range of 24Ω to 600Ω, it provides stable drive for everything from high-sensitivity earphones (e.g., Ca*pfire Audio Satsuma 105dB/mW) to high-resistance over-ear headphones (e.g., Senn*eiser HD600 300Ω). The 30V voltage boost design ensures high-volume playback with low distortion. It also improves the reproduction of subtle changes in sound pressure, especially when using headphones with impedances of 200Ω or higher. [Sound quality customization mechanism] Two interchangeable NE5532 op-amps are included as standard. They can be replaced with compatible chips (output current 50mA or more) that comply with the 8-pin DIP package standard. Tone adjustment examples: Use the LME49720NA to improve high-frequency resolution, or the OPA2134PA to increase mid-range depth. The socket mounting method means that replacement is possible without the need for soldering or tools. Highly Stable Power Supply Design: Designed specifically for the included DC5V/2A adapter. Achieves a signal-to-noise ratio of over 110dB, suppressing background noise below the audible range when there is no signal. The power supply circuit is equipped with a three-stage noise filter (rectification, smoothing, and high-frequency rejection). Using a non-recommended adapter may result in output voltage fluctuations, so we recommend using the included adapter.

Compact Heat Dissipation Structure: The aluminum alloy housing (78 x 82 x 32 mm) improves heat dissipation efficiency. Four heat dissipation grilles are placed on the bottom to control heat buildup during continuous operation. Despite its compact design weighing just 210 g, it comes standard with non-slip rubber feet that ensure stable placement even when inserting a large plug into the 6.35 mm jack.
