S1 Pro Microphone vs Guitar Volume

Question

Why do I have to turn up the microphone higher than guitar?

Answer

The output level of the guitar is louder than the output level of the microphone. That's why we have to turn up the microphone higher.

In the picture above the

1. Microphone is connected to channel 1
2. Guitar is connected to channel 2

The volume on channel 1 (microphone) is higher than on channel 2 (guitar) because the signal from the microphone is lower than from the guitar.

More information

• The power amps are running at full volume
• The volume controls are trim controls:
• Note how quiet the S1 Pro is when there’s no input source and the volume, is all the way up – The volume controls are trim not preamp/gain controls
• The center détente is a convenient point of reference, especially when you can't see the controls well at a gig
  It is not an indication of a specific amount of gain
• When you turn the volume controls all the way up, you have reached the maximum volume the S1 Pro is capable of producing for that source
• Note the clip lights. If you see red, turn down to avoid distortion. You have reached the maximum usable volume just below clipping

We hit maximum usable volume for an input is just before the clip lights come on. With a guitar with a preamp, that might be at 12:00 o’clock compared to a microphone at 3:00-4:00 o’clock.  There’s no dysfunction here. It’s a reflection that the output level of the guitar is higher than the microphone.
