Introduction:
This audio DSP board is equipped with the necessary components to install and demonstrate firmware. All the customer has to do is connect and play. Select AA-AP23122 and you will get this DSP board as shown in Figure 1-2. Customers also need an audio DSP expansion board ADAU1701 2 x 3, a stereo audio player, audio amplifier (or headset) connected via 3.5 channels or RCA, and most importantly, a flexible audio DSP connector (10-pin extension cable) Comes with an expansion board). After connecting the board of the kernel expansion interface board, just start the kernel board universal microUSB cable, then adjust the main volume, three volumes, bass volume and switching frequency on the on-board potentiometer, in addition to the slide switch on the boat to mute or enable audio output. Select the AA-AA11428 interface expansion board. Thanks to all available audio DSP interfaces, including analog and digital audio inputs and outputs, control IOs and I2C programming interfaces, the audio DSP board can provide a platform for the ADAU1701 to easily integrate digital audio applications with an affordable price.
Advantages:
High sound quality
This audio DSP board uses the signal processing analog device ADAU1701 compara-ble found in high-end studio equipment. The dynamic range of the two Σ-Δadc and the four Σ-Δdac reach a height of 98.5 db. Each ADC has a THD + N -83 dB and each DAC (THD + N -90 dB. In addition, power filtering and signal loop optimization PCB layout and capacitive components also contribute to high sound quality.
