Configuración
1. Conexiones físicas
Refer to the diagrams below for proper connection of audio inputs, outputs, and power.
Figura 1: Conexiones del panel trasero. 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.
- Conexión de energía: Connect a DC 5V, 1A power supply to the USB Type-C port labeled "DC INPUT 5V, 1A" on the rear panel.
- Entrada de audio: Connect your audio source (e.g., media player, pre-amplifier) to the "LINE IN" RCA jacks (ADC0 Left, ADC1 Right).
- Salida de audio: Conecta tu 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. Encendido inicial
Once all connections are secure, apply power to the unit. The "POWER" LED on the front panel should illuminate, indicating the device is operational.
Instrucciones de funcionamiento
The WONDOM ADAU1701 DSP Preamp features several controls on its front panel for direct adjustment, as well as advanced programming capabilities via SigmaStudio.
Figura 2: Controles del panel frontal. 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.
Controles del panel frontal:
- LED DE ALIMENTACIÓN: Indica que la unidad está encendida.
- 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): Controla el volumen general.
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.
Figure 4: SigmaStudio Programming Setup. This image illustrates the connection between the DSP unit and an ICP5 programmer, along with a visual representation of the SigmaStudio graphical programming interface.
- Software: Download and install SigmaStudio from the Analog Devices websitio.
- Hardware: Connect the ICP5 programmer to the ICP Port on the DSP unit and to your computer via USB.
- Programación: Utilize the open-sourced demo program and HEX files provided by WONDOM to get started or to restore factory settings. All terminal functions can be tailored to specific needs using SigmaStudio.
Mantenimiento
- Mantenga la unidad limpia frotándola con un paño suave y seco.
- Evite utilizar productos químicos agresivos o limpiadores abrasivos.
- Asegúrese de que haya una ventilación adecuada alrededor de la unidad para evitar el sobrecalentamiento.
- Compruebe periódicamente que todas las conexiones de cables estén bien ajustadas.
Solución de problemas
| Problema | Posible causa | Solución |
|---|---|---|
| Sin energía / LED de encendido apagado | 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. |
| Sin salida de audio | 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). |
