Micro 1 / Voicetron
You can connect up to two different microphones at the MICRO1 and MICRO2 inputs located on
the BACK PANEL of the instrument. To achieve optimal signal to noise ratio, you need to adjust
the input gain with the potentiometers located next to the input ports. To set the optimal gain level,
talk or sing into the microphone: if the gain is too high the signal will be distorted, if the gain is too
low, the signal level will be too soft and could be inaudible. Always use good microphones and
cables.
When connecting a microphone to the instrument, basic precautions should be followed, including
the following:
• Always turn the volume down, before connecting a microphone.
• Keep the microphone away from the loudspeakers to avoid feedbacks (Larsen effect).
• Prefer microphone with a cardioid polar pattern to minimize feedback chances.
• Keep the microphone far from cables and power lines.
• Use heavy duty, robust microphone stands.
• To avoid damage, remember that the loudspeakers are the first piece of equipment to be
powered down and the last to be powered on.
Microphone signal path
Both MICRO1 and MICRO2 signals go through an additional effect chain, composed of:
• NOISE GATE: attenuate signals that below a defined threshold. Used to filter out floor
noise.
• 4 BANDS PARAMETRIC EQUALIZER
• COMPRESSOR: reduces the dynamic range.
• ECHO: creates replica of a signal after some duration of time.
• PITCH SHIFT: increase or decrease the pitch of the voice, changing drastically the voice
timbre.
• TALK REVERB: reverb unit to be used when the TALK mode is enabled. In general, the
length of this reverb is short to increase the intelligibility of the speech.
To edit these and modify these effects, see MICRO EDIT. After the effect chain, the MICRO1 and
MICRO2 signal paths slightly differs:
• Because the MICRO1 input port is built specifically for the voice, the audio signal is
processed by the VOICETRON.
