Nobsound HiFi 2.1 Channel Digital Amplifier Bluetooth 5.0 Receiver Home Stereo Subwoofer Power Amp 300W*2+600W | Электроника

Warm tips:   1. Bluetooth input with priority. Please make sure the Bluetooth is disconnected when using line input.   2. This is 2.1 channel amplifier, if you want 2.0 channel of the same series please click: LINK and mono channel please click: LINK

• Support wired stereo RCA and wireless Bluetooth audio inputs, with strong compatibility, can be perfectly matched with most audio devices such as MP3, phone, tablets, computer, TV, CD player, DAC and so on.

• 2.1 channel output with super large power: adopting 2PCS TPA3255 amp IC, max output can reach 300W+300W (L/R)+600W(subwoofer), easily to drive large passive bookshelf/ computer/ desktop /ceiling /floor standing /outdoor speakers and subwoofers and also matched very well with them.

• With tone control and HiFi sound: treble, mid and bass can be adjusted independently to provide much delicate sound that suits different listening style, and a bypass switch(treble knob) is specially designed to turn on/off the tone control to enjoy original sound, adding much fun and higher playability.

• Unique circuit design and high quality components are used to ensure HiFi sound and long time stable work:

Built-in large power high-efficiency switching power supply, with unique three-stage filter protection output and feedback correction design, the power can be auto adjusted according to the output power and size of speakers, variable stepless adjustment to ensure rapid response when high-power output, and reduce temperature to save energy when low power output.   2PCS TI's original TPA3255 power amplifier chip, with high efficiency, low distortion, no background noise and ultra-low static power consumption.   QCC3034 Bluetooth chip, with strong compatibility and supports APTX and APTX-HD lossless transmission.   PCM5102 decoding chip, its dynamic range can up to 112DB, THD is -93DB, and output is 2.1V RMS audio voltage. High frequency is still smooth and low frequency is powerful.   6PCS NE5532 op amp, responsible for pre-amplification, tone control and frequency adjustment, the sound is more natural and delicate.   AC 100-240V working voltage for global use and with perfect protection circuit, use high-precision chip resistors for better signal-to-noise ratio, and special inductance for audio to ensure clear and powerful sound.
