Рисунок 1: З’єднання на задній панелі. This image shows the rear panel of the ADAU1701 DSP Preamp, highlighting the DC Input (5V, 1A), ICP Port, Line In (ADC0 Left, ADC1 Right), and Line Out (DAC0 Right, DAC1 Left, DAC2 Right, DAC3 Left) RCA jacks.

Підключення живлення: Connect a DC 5V, 1A power supply to the USB Type-C port labeled "DC INPUT 5V, 1A" on the rear panel.
Аудіо вхід: Connect your audio source (e.g., media player, pre-amplifier) to the "LINE IN" RCA jacks (ADC0 Left, ADC1 Right).
Аудіовихід: Підключіть свій amplifiers or powered speakers to the "LINE OUT" RCA jacks. The default configuration provides 2-channel mid-range output (DAC2 Right, DAC3 Left) and 2-channel bass output (DAC0 Right, DAC1 Left) for a 2-way digital crossover setup.
ICP Port: This port is used for connecting an ICP5 programmer (sold separately) for advanced SigmaStudio programming.

2. Початкове увімкнення

Once all connections are secure, apply power to the unit. The "POWER" LED on the front panel should illuminate, indicating the device is operational.

Інструкція з експлуатації

The WONDOM ADAU1701 DSP Preamp features several controls on its front panel for direct adjustment, as well as advanced programming capabilities via SigmaStudio.

Рисунок 2: Елементи керування на передній панелі. This image displays the front panel, showing the Power LED, Busy LED, SW1 (Mute) and SW2 (Phase) switches, and four potentiometers (POT1, POT2, POT3, POT4) for various audio adjustments.

Елементи керування передньої панелі:

Світлодіод POWER: Показує, що пристрій увімкнено.
BUSY LED: Indicates DSP activity.
SW1 (Mute Switch): Toggles audio output mute on/off.
SW2 (Phase Switch): Adjusts the phase of the audio output.
POT1 (MP3 / ADC2): Controls the High-Pass Filter (HPF) for Bank B (3kHz-20kHz).
POT2 (MP8 / ADC3): Controls the Low-Pass Filter (LPF) for Bank A (210Hz-3kHz).
POT3 (MP9 / ADC0): Controls the High-Pass Filter (HPF) for Bank A (10Hz-310Hz).
POT4 (VOL): Контролює загальну гучність.

Digital Crossover Configuration:

The unit's default output is configured as a 2-way digital crossover, providing dedicated outputs for bass and mid-range frequencies.

Figure 3: 2-In, 4-Out Digital Crossover. This diagram shows the RCA jack assignments for 2-channel Line Input, 2-channel Mid-range Output, and 2-channel Bass Output, facilitating a 2-way digital crossover setup.

2CH Line Input: ADC0 Left (White), ADC1 Right (Red).
2CH Mid-range Output: DAC2 Right (Red), DAC3 Left (White).
2CH Bass Output: DAC0 Right (Red), DAC1 Left (White).

SigmaStudio Programming:

For advanced customization and fine-tuning of the DSP functions, the unit supports programming via Analog Devices' SigmaStudio software. An ICP5 programmer (sold separately) is required to connect the DSP unit to your computer.

Технічне обслуговування

Тримайте пристрій у чистоті, протираючи його м’якою сухою тканиною.
Уникайте використання агресивних хімікатів або абразивних засобів для чищення.
Забезпечте належну вентиляцію навколо пристрою, щоб запобігти перегріву.
Регулярно перевіряйте всі кабельні з'єднання на предмет надійності кріплення.

Усунення несправностей

проблема	Можлива причина	Рішення
Немає живлення / Світлодіод живлення не горить	Incorrect power supply, loose connection, faulty cable.	Verify DC 5V, 1A power supply. Check USB Type-C cable connection. Try a different power source or cable.
Немає аудіовиходу	Incorrect input/output connections, Mute switch engaged, volume too low, faulty audio cables.	Check all RCA connections. Ensure SW1 (Mute) is disengaged. Increase POT4 (Volume). Test with different audio cables.
Audible hiss or noise	Ground loop, interference, power supply noise, high gain settings.	Ensure all components are properly grounded. Use a high-quality, stable 5V power supply (a separate USB power bank/battery can help reduce noise from PC USB). Reduce gain settings if applicable.
Cannot connect to SigmaStudio	ICP5 programmer not connected or faulty, DSP not powered, incorrect software drivers.	Ensure ICP5 programmer is correctly connected to the DSP and computer. Verify DSP unit is powered on. Install SigmaStudio drivers in administrator mode (as suggested by user reviews).
