Description:
- CSR8675 digital audio signal reception, SPDIF coaxial number signal transmission to ESS
- The 9038Q2M chip decodes and outputs analog audio signals that are amplified and filtered by 3 dual op amps.
- The LDAC875 module supports wireless Bluetooth reception and AUX analog audio input for switching output. The relay is used for non-destructive switching without any impact on the sound quality. The module defaults to AUX line mode, - the switching mode is automatic switching, and Bluetooth is preferred. The LDAC875 module supports the LDAC APTX HD/APTX-LL / APTX / SBC / AAC, with a maximum sample rate of 24bit / 96khz
- LDAC875 is powered by a single DC power supply, and a wide voltage range of DC 10V-32V can be used. The product is designed with an isolated power regulator module that can directly share power in the original power amplifier or pre-stage equipment, and no longer needs to supply power separately. It can also be used for vehicle modification.
- The board comes with an isolated power regulator module that directly connects to the 12V power supply on the car. Voltage stabilization design. The Bluetooth module, DAC chip and op amp chip are powered by independent power management chips. The op amp uses dual (positive and negative) 14V power supply.
1 Power input, red (EXACC) is +, black (GND) is-
Support DC10V-32V, note: AC power cannot be used.
② AUX analog audio input interface, the door color line (INL) is the left channel, black (GND) is the audio ground line, and red (INR) is the right channel. Note total: The audio ground wire cannot be connected incorrectly .
③ Audio output interface, the white line (L-OUT) is the left channel, and the black (GND) is
Audio ground cable. Red (R-OUT) is the right channel.Note: The audio ground wire cannot be connected incorrectly.
④ The bluetooth external antenna is buckled, and the antenna with a buckle can be connected to the buckle. A 2.4G antenna can be used.
The module must be installed in a metal case with an external antenna. Otherwise, the receiving distance will be seriously affected.
