Connect the 520DX directly into a guitar amplifier to produce the classic blues harp sound. Use the following guidelines:
The volume control on the microphone should be turned down before plugging it into an amplifier. As you move away from the amplifier, the volume can be turned up.
Adjust the microphone's volume control knob during performances as needed. For example, when switching from playing rhythm to lead or to place the microphone on standby between sets.
To avoid feedback, maintain as much distance as possible from monitors or loudspeakers. Adjust the volume of monitors or loudspeakers at the mixing console so that no feedback is present when the volume control knob on the harmonica microphone is at its maximum setting.
