Audio are actually three cables inside the same casing. They're braided in such a way that they have a natural coil to them.

Coiling them improperly can damage audio cables. That's why they need to be wrapped properly.

xlr
An XLR is a circular, usually three-pronged, cable used commonly for carrying audio signals.

The origin of the name is a long story. The "X" comes from the "Cannon X" series, its original manufacturer. The "L" comes from a latching mechanism that was added later on. The "R" comes from the rubber insulation found around the cable.

quarter-inch
A quarter-inch cable (also sometimes called a "microphone cable" or a "patch cable") is frequently used along with XLRs to carry audio signals. You'll use this cable for most instruments that need additional amplification or sound processing before the signal is sent to a speaker.

It's so named because the ends fo the cable are 1/4 of an inch in diameter.

iem-extensions
A 3.5 mm cable is the cable used by most headphones and earbuds today. It's so named because the ends of the cable are 3.5 mm in diameter.
lithium-battery
There are several main kinds of batteries: ALKALINE, and LITHIUM, and Ni-MH.

ALKALINE batteries are typically non-rechargeable. Putting an alkaline battery in a charger can cause the battery to overheat, which is a fire hazard. So don't ever put an alkaline battery in a charger.

The batteries that we use are rechargeable LITHIUM and Ni-MH (Nickel-Metal Hydrate) batteries. They should be plugged into the chargers when not in use.
ProDI
DI stands for "Direct Input". It's used to transform a high-impedance signal (like from a guitar or keyboard) into a low-impedance signal. This helps get rid of distortion and noise when playing.

There are passive and active DIs. Passive ones don't require power while active ones do. All the DIs we have at Creo are passive DIs.
ProDI
First, connect your instrument to the DI with a quarter-inch cable into the "INPUT" port.

Next, connect the DI to the right channel with an XLR.

Pressing in the "LIFT" button switches on Ground Lift, which can help reduce humming.

If you have the "PAD" button pushed in, this will reduce the volume of your signal by 15 dB. You generally don't want to do this unless the sound techs ask you to do it.

The "THRU" is a separate output (NOT an input) that is normally used to send the signal to another amplifier, like one on stage. We don't normally use this.
Check out this tutorial video! Note that this is for a different church, but the main principles remain the same:
On you phone's Wi-Fi settings, connect to Tenth Gym. The password is "earsacce$$".
The Tenth Gym network is only connected to the mixer, not the Internet.

If you want Internet access, you'll need to connect to tenth-public or cellular data.
