Connecting Your Audio System
Before you begin, here are a few rules to get you started:
4
Always turn down the Main and Mix faders in UC Surface as well as the Phones
level before making connections. Conversely, you can also enable Mute All.
4
Before plugging or unplugging a microphone while other channels
are active, mute the channel to which you are connecting.
4
Your faders in UC Surface should be set on or near the
“U” mark whenever possible. The “U” indicates unity gain,
meaning the signal is neither boosted nor attenuated.
4
Do not allow your inputs to clip. Watch the level meters; when signal nears
Clipping, the channel LED illuminates red, indicating that the analog-to-digital
converters are in danger of being overdriven. Overdriving the converters
will cause digital distortion, which has a negative effect on sound quality.
Your P.A. and studio equipment should be powered on in the following order:
4
Sound sources (keyboards, direct boxes, microphones,
etc.) connected to the StudioLive inputs.
4
StudioLive mixer
4
Computer (if applicable)
4
Power amplifiers or powered loudspeakers
When it is time to power down, your system should be turned off in the
reverse order. Now that you know what not to do, let’s get started!
