# Powering up Omnia XII

After making physical connections to the Omnia XII, you are ready to power up the unit for the first time.

**To power on Omnia XII:**

1. Locate the IEC power cord for your location.

Omnia XII ships with two USA/Canada IEC power cords.
2. Connect AC power to one of the Omnia XII back panel **PSU** jacks using the appropriate power cable for your location.

> [!NOTE]
> **Note:** There is no power switch.

When the Omnia XII is first powered on, the fans turn on and the front panel touchscreen displays text-based boot status messages followed by some graphics test screens and then the home screen. Home screen metering appears frozen for a while as the I/O board finishes booting up. This is normal. This process may take up to two minutes.

When boot up completes, a green light appears around the knob, the respective **PSU** (power supply) indicator lights blue, and the **STAT** (status) indicator lights green.

The front panel touchscreen defaults to its Home screen, which includes:
  - Omnia XII logo (for access to touchscreen menus)
  - Touchscreen header that displays bar-graph meters, the current preset, and a headphone level control
  - Meters: **Wideband**, **St. Enhancer** (stereo enhancer), **Multi AGC** (five-band), **Multi Compressor** (five-band),

**Multi Limiter** (six-band), **Bass Clipper**, **Clipper**, **Final Limiter** (L/R), and **Sensus**
