5. Operating Instructions

5.1. Gain Control and Indicators

Adjust the GAIN1 and GAIN2 knobs to set the input level for your microphone or instrument. The 3-color LED indicators provide real-time visual feedback on your input signal level:

• Green: Normal signal level.
• Yellow: Signal is approaching peak, limited.
• Red: Signal is clipping, indicating potential distortion. Reduce the gain immediately.

5.2. Line In / Instrument Input Switching

The LINE/INST switch allows you to optimize the input impedance for different sources:

• Set to LINE for line-level devices such as keyboards, synthesizers, or external preamps.
• Set to INST for high-impedance instruments like electric guitars or basses.

5.3. Monitoring Modes

The Synido Solo offers three monitoring modes, selectable via the MONITOR switches, to suit various applications:

• Stereo Mode: Provides independent left and right channels, presenting the original input signal (e.g., microphone or instrument). Ideal for accurate recording.
• Mix Mode: Blends the input audio with the computer's audio in real-time. Suitable for live streaming or recording where you need to hear both your input and playback simultaneously.
• USB Mode: Monitors only the computer's audio. Useful for post-editing or when processing audio solely from your computer.

The Synido Solo Audio Interface is compatible with various Digital Audio Workstations (DAWs) on Windows and Mac OS. Additionally, dedicated host software may be available for PC, offering features such as microphone mute, play mute, and pre-installed EQ settings. Refer to the Synido website for software downloads and instructions.

  • Ensure the interface is selected as the default audio input/output device in your computer's sound settings and DAW.
  • Verify that the monitor volume knob is turned up.
  • Check the monitoring mode (Stereo, Mix, USB) to ensure it matches your intended audio source.
• No Input Signal:
  • Confirm that the microphone or instrument is properly connected.
  • Adjust the GAIN knob for the respective input channel.
  • If using a condenser microphone, ensure 48V phantom power is activated.
  • For instruments, verify the LINE/INST switch is set correctly.
  • Check the input selection in your DAW.
• Distorted Sound:
  • Reduce the GAIN knob if the red LED indicator is consistently lit.
  • Check for damaged cables.
  • Ensure the LINE/INST switch is correctly set for your input source.
• Latency Issues:
  • Adjust the buffer size settings in your DAW to a lower value (this may increase CPU load).
