2. Plug the power supply into an appropriate AC outlet.

3.2 Аудио везе

The IR-D offers various connection options for different setups:

• To an Amplifier's Power Amp Улаз: Connect the "OUTPUT" jack of the IR-D to the "FX Return" or "Power Amp In" of your guitar amplifier using a standard instrument cable. This bypasses your amplifier's preamp одељак.
• To a Mixer/Audio Interface (DI): Use an XLR cable to connect the "BALANCED OUT" jack to a mixer, audio interface, or PA system. This output includes the IR cabinet simulation.
• Слушалице: Connect headphones to the "HEADPHONES" jack for silent practice. The headphone output also includes IR cabinet simulation.
• Петља ефеката: External effects pedals can be connected via the "SEND" and "RETURN" jacks. Connect the "SEND" to the input of your effects pedal and the output of your effects pedal to the "RETURN" jack.
• УСБ веза: Connect the "USB" port to your computer using the included USB cable for IR loading, firmware updates, and software control.

КСНУМКС. Решавање проблема

If you encounter issues with your Friedman IR-D, refer to the following common troubleshooting steps:

• Нема напајања:
  • Ensure the 12V DC power supply is securely connected to both the IR-D and a working AC outlet.
  • Verify the power supply is the correct voltage and current rating (12V DC, min 800mA).
• Нема звука:
  • Check all audio cable connections (input, output, effects loop).
  • Ensure the VOLUME knobs on the IR-D are not set to zero.
  • Ако користите amplifier, ensure its volume is up and it is set to the correct input (e.g., FX Return).
  • If using the BALANCED OUT, check mixer/interface input levels and phantom power settings (if applicable, though IR-D does not require it).
  • Test with different cables and instruments to rule out external issues.
• Зујање или шум:
  • Engage the "GND LIFT" switch on the rear panel if using the BALANCED OUT.
  • Ensure all power cables are away from audio cables to minimize interference.
  • Test in a different electrical outlet or with a power conditioner.
  • Check for faulty cables or other noisy equipment in your signal chain.
• Unexpected Tone/Functionality:
  • Ensure the correct channel is selected and the boost is engaged/disengaged as desired.
  • Check the CAB/IR switch settings.
  • If using custom IRs, verify they are loaded correctly via the software.
  • Perform a factory reset if issues persist (refer to the Friedman website for instructions on how to perform a factory reset).

If these steps do not resolve the issue, please contact Friedman customer support for further assistance.
