• Do not place the DigiMaster X in a metallic cabinet (shielding effect could occur).
Placement

• Connect the DigiMaster X audio output with the
microphone input of the amplifier. Use
professional-grade audio cables.

• Position the microphone correctly and switch On
DigiMaster X
• Increase the DigiMaster X’s volume up to + 8dB via the
inspiro menu
• Increase the input gain of the amplification system until
acoustical feedback occurs
• Reduce the gain of the amplification system until the
feedback disappears
• Walk around the room and check that every position is free
of feedback
• Reset the DigiMaster X’s volume to 0dB or the newly
desired volume via the inspiro menu
