D325Q 300Wx2 High Power Audio Amplifier HiFi Multifunctional Bluetooth5.4 Digital Power Amplifier TPA3255

Description:
- D325Q is a machine that combines appearance and sound quality. The front panel is embedded with a piece of tempered glass, which not only has an outstanding feel, but also is very high-end. Built in digital control volume chip NJW1194V, with less distortion, lower noise, no distortion, built-in high and low frequency adjustment function, supports remote control function, with display screen, more convenient to use.
- Multi functional color screen, supporting remote control function, more convenient to use.
- Bluetooth 5.4 reception provides better long-distance connection and high-quality sound quality.
- The materials used for D325Q are full of sincerity, and the RCA socket is gold-plated for greater durability. The machine is designed with the amplifier chip tightly attached to the chassis shell for heat dissipation, which has the advantage of having a larger heat dissipation area and a much better heat dissipation effect than the built-in heat sink. It can work stably for a long time. The FM series large capacity filtering capacitor for Panasonic makes the power supply more stable and has lower ripple. The LPF circuit uses capacitors for WIMA, and the coupling part uses advanced capacitors for ELNA, all of which are high-grade materials. The operational amplifier used is JRC5532. The amplifier chip uses TPA3255, which can output a strong power of 300W per channel and can be used to push various large speakers without any pressure. The QCC3084 Bluetooth module is used for Bluetooth, which supports LDAC lossless transmission. The PCM5102A is used for Bluetooth decoding, making the sound quality of Bluetooth beautiful for wired transmission. The USB input uses the receiving function of the QCC3084 module, with a bit rate support of 96K 24BIT and outstanding performance.

Highlights:
- Bluetooth 5.4 Chip: Equipped with an upgraded 5.4 chip, it responds quickly, ensuring fast transmission of Bluetooth signals and rejecting delays/lags.
- The knob is made of solid aluminum material and can be adjusted for treble and bass: the customized black solid aluminum knob is beautiful and elegant, with white small embellishments on the periphery to enhance the visual effect.
- 300W strong power: can be used to push various large speakers.
- Five input methods: not only supports RCA, AUX, XLR input, but also Bluetooth and USB input, making it easy to connect different devices and having strong compatibility.

Using Instruction:
- The D325Q output can only be connected to passive speakers and cannot be connected to active speakers or constant voltage speakers.
- The D325Q is powered by DC24V-48V. The higher the voltage, the greater the power, but it cannot exceed 48V, otherwise it will burn out the amplifier. The power plug is 5.5x2.5, positive inside and negative outside.
- After the first power on of D325Q, the screen lights up and automatically turns on. Simply rotate the knob to adjust the volume, short press the knob to switch inputs, and long press the knob to enter the treble and bass adjustment mode. Entering this mode will only display "TREB", which is treble adjustment. Twisting the knob can adjust the treble gain. Then press the knob briefly again to display "BASS", twist the knob to adjust the bass gain. Alternatively, it can be conveniently adjusted using a remote control.
- The negative terminals of the left and right channels of the amplifier output cannot be connected together, otherwise it will cause the amplifier to burn out.
- When using Bluetooth, switch the input to BLU, search for the Bluetooth name "YJCO-QCC3084" on your phone to connect, and then you can play Bluetooth music.
- USB playback is also required by switching the input to BLU mode. The USB input can be connected to a phone's USB port or a computer, and can be played directly without installing a driver. When connecting OTG to USB on a mobile phone, an OTG cable is required, the charging cable cannot be used, and USB cannot be connected to a USB flash drive.
