PGNEX Pre-Amplifier Module Digital Audio Front Amplifier Board Preamplifier 5 Times Rate Wide Voltage

Description

• The XH-A902 audio preamplifier board uses the original imported op-amp chip, which is more than similar OP-amps. Less noise bottom. It is suitable for all audio amplifiers amplified by a wide range of preamplifiers, with a wide voltage input DC12~30V.
• XH-A902 audio preamplifier board, it is an audio preamplifier, directly connected to the speaker does not sound.
• It needs to connect the amplifier to the audio output and the power supply to the speaker to have sound.
• It connects the 12-30V power supply to the power input of the op amp board, paying attention to distinguish the positive and negative terminals, and VCC is the positive terminal.
• In the event of an overload, the device reports the fault to the processor, thus avoiding damage to itself.
