Default Configuration
Front Panel
-
Power LED
Indicating the power When the device is powered, th is LED will be ON. -
BUSY LED
BUSY LED is controlled by MP7.
When MP7 is used as GPIO pin, set at high level, the BUSY LED will be OFF;
set at low level, the BUSY LED will be ON. MP7 is not defined now. You can customize its function in Sigma Studio.
When MP7 is set as 12S1 data input, the LED will be ON when there is signal, OFF when there is no signal. -
SW1- Mute Control
SW1 functions as mute control.
When set at 1, device will mute, set at 0, device will unmute.
The port corresponds to MP0/GPIO0, where OPEN is 1 and SHORTED is 0. -
SW2 – Phase Control
SW2 functions as phase control.
When set at 1, phase is 180°;
when set at 0, phase is o°;
The port corresponds to MP6/GPIO6, where OPEN is 1 and SHORTED is 0. -
POT1 – HPF of BANK B
Potentiometer 1 functions as the High-pass filter for Mid-range output channel (BANK B) and is correspondent with MP3 or ADC2 in program. The default frequency adjustment range is 3kHz to 20kHz.
The adjustable frequency range can be modified through Sigma Studio. -
POT2 – LPF of BANK A
Potentiometer 2 serves as the controller for MP8/ADC3. POT2 works as the Low- pass filter for Bass output channel (BANK A). The default frequency adjustment range is 210Hz to 3kHz.
The adjustable frequency range can be modified through Sigma Studio. -
POT3 – HPF of BANK A
Potentiometer 3 operates as the controller for MP9/ADC0. POT3 serves as the High-pass filter for Bass output channel (BANK A). The default frequency adjustment range is l0Hz to 310Hz.
The adjustable frequency range can be modified through Sigma Studio. -
POT4 – Overall Volume
Potentiometer 4 functions as Master volume control.
When rotating POT4 clockwise, the overall volume will increase.
When rotating POT4 anticlockwise, the overall volume will decrease.
Rear Panel -
Power Supply
A USB Type-C port is mounted on the rear panel for powering the AOSP1701-2.4U.
Power supply requirement: OCSV, 1A -
POTS – Relative Gain Control
POTS is defined as the Relative Gain Control potentiometer. The control range is -60dB to 0dB.
When rotating POTS clockwise, the gain of BANK A output remains at 0dB, while that of BANK B output channel will gradually attenuate to -60dB.
When rotating POTS anticlockwise, the gain of BANK B output remains at 0dB, while that of BANK A output channel will gradually attenuate to -60dB.
Please refer to the functional diagram.
In addition, the functionality of POTS can be customized with Sigma Studio.
As is shown in the label, POTS is controlled by MP2/ADC1. -
ICPPORT
This port is for connection with WONDOM ICP programmer. The unit will support Sigma Studio programming after connection with ICP programmer.

Comprehensive Programming Support
Thanks to the integrated ADAU1 701 DSP, the ADSP1 701-2.4U supports Sigma
Studio programming after connection with ICPS through the ICP port on the rear
panel. You can customize the ports functionality according to your
requirements.
To enhance the programming experience, we have implemented improvements on the
silkscreen design of our preamp unit . Each interface is now labeled with its
corresponding program resources, making it easier for you to locate and modify
the program as needed.
WONDOM provides comprehensive support for customers’ use with ADSP1701-2.4U,
including open-sourced demo program, HEX file for restoring factory settings,
programming guide and video tutorials. Scan the QR codes to get more details.
