The +48V phantom power can be individually enabled for each mic input.
Power User Tip: Phantom power is a system for powering condenser
microphones, DI boxes, and other devices by supplying a DC voltage
over a mic cable. The StudioLive CS18AI controller supplies +48V,
which is the most commonly used phantom power voltage.
Note: Always be sure that phantom power is disabled for an
input before plugging or unplugging a microphone.
Line-level sources can be connected to the combo jacks instead of microphones. The
line inputs bypass the preamps, going directly to the analog-to-digital converters.
The CS18AI rear panel includes two TRS Line Input jacks. These jacks
provide additional line inputs for sources from front-of-house, such
as 2-track or computer playback. On a StudioLive RM-series mixer
connected to the CS18AI via AVB, these two inputs show up as digital
returns 33 and 34, which appear on the Returns layer as Dig Ret.
Power User Tip: Monitor selection in the CS18AI uses the controller's
monitor facilities and affects only the CS18AI. StudioLive RM-series mixers'
monitor facilities are controlled using the front panel of the RM mixer or UC
Surface and are entirely independent of the selections on the CS18AI.
A ¼-inch stereo headphone jack is located on the front right
corner of the CS18AI front panel, just under the armrest.
• To control the level appearing at the Phones output, adjust the
Phones knob in the Monitor area of the CS18AI's front panel.
