Product Description

 Introduction of Audio Module

1.1. Product Profile
XBPA-2401 is a high-performance 10/100M network audio module, which uses ARM + DSP architecture, can receive network audio data stream, convert it into audio analog signal output, and has CD-level playback quality.
XBPA-2100 module has a very complete interface. Users can develop their own network audio terminal without any circuit: IP broadcast stud, network player, network on demand terminal and so on.
II. Interface Description
2.1. Product Specifications
XBPA-2401 uses dual-processor architecture of ARM and professional audio DSP. ARM processor is responsible for data transmission, user command analysis and execution, and power amplifier interface control. Professional audio DSP is responsible for speech data encoding, decoding and output. Through network interface, XBPA-2401 can be directly connected to ethernet. Its internal structure is as follows:
Power input: 12V-24V DC power supply
Network Interface: 10/100M Base Network, RJ45 Interface, 1.5KV Electrical Isolation, Receiving and Sending Data Indication
Line output: typical amplitude 1500mVpp, THD < 0.3%, internal resistance 500_, signal-to-noise ratio 83 dB
Power amplifier output: 15W *2, for external 4~8Omega speakers;
Control Serial Port: By controlling the working and reading status of the serial port control module, it can also be used for communication.
Usage environment: Operating environment: 0 55 C, 5 95% humidity
Storage environment: - 20 85 C, 5 95% humidity
Network features: support ICMP, ARP, TCP, UDP, HTTP, DNS, DHCP, IGMP network protocols;
2.2. Ethernet Interface
XBPA-2401 provides a standard 10/100M Ethernet interface, which connects to the Ethernet with RJ45 connectors. The pin meanings of RJ45 connectors are as follows.
Pin number
1. TX + Ethernet Sends Positive Signals
2. TX-Ethernet Sends Negative Signals
3. RX+Ethernet Receives Positive Signals
6. RX-Ethernet Receives Negative Signals

YLED Data Transmitting and Receiving Indicator Lighting When Transducer Sends or Receives Data
GLED Network Connection Indicator
2.3. Line Output
XBPA-2401 provides 2*15W or 1*40W audio power amplification. When this power amplification can not meet the requirements, a larger power amplifier can be expanded, and the line output of XBPA-2401 can be connected to the signal input of the external power amplifier.
2.4. Volume regulation
XBPA-2401 provides a volume control knob to adjust the volume of the local speaker.
