Setup

2. Connecting In-Ear Monitors
Connect your in-ear monitors (IEMs) or headphones to the 3.5mm (1/8-inch) headphone output jack located on the top of the P3RA unit (refer to Figure 4).
3. Powering On
To power on the P3RA, rotate the volume knob clockwise until the display illuminates. To power off, rotate the volume knob counter-clockwise until the display turns off.
Operating Instructions

Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the unit. Avoid using harsh chemicals or abrasive materials.
