Video equipment connection:
PC -> USB TO 4AES -> 4AES TO HDMI -> HDMI TO 4AES -> AES TO active monitor speakers
4AES is 4-channel AES/EBU digital audio signal, that is, 8-channel audio signal
1. USB TO 4AES: $120
2. HDMI TO 4AES: $190, DSP expansion card: $30
3. 4AES TO HDMI: $258.
USB TO 4AES
1. Supports WIN, Apple, and Android systems, plug and play. There are two models, one is an external USB interface box, and the other is a full-height computer baffle.
HDMI TO 4AES
1. Two HDMI inputs, one HDMI output, and the output supports up to 4K@30Hz.
2. 4 groups of AES/EBU outputs. The audio format required for HDMI transmission is LPCM, with a maximum of 8 channels
3. The DSP function can be expanded. The DSP expansion card is realized through the 4 groups of I2S interfaces on the motherboard. To use the DSP function, you need to use the sigma studio tool and have the USBi tool.
4. With remote control, multiple functions can be realized
4AES TO HDMI
1. 4 groups of AES/EBU input (can be changed to 8-channel analog input through appropriate modification), 1 HDMI output.
2. 4AES/EBU input can be input through DB25 or RJ45 interface.
3. Each group of AES/EBU input has ASRC sampling conversion function. The audio in HDMI is output at a fixed 48KH sampling rate.
4. Volume adjustment and other algorithms can be realized through the expanded DSP function.
