5. Setup
5.1 Qawwa tal-Konnessjoni
- Ensure the A70 Pro is turned off.
- Connect the provided AC power cable to the power input on the rear panel of the A70 Pro.
- Ipplaggja t-tarf l-ieħor tal-kejbil tal-enerġija f'sokit tal-ħajt adattat.
5.2 Konnessjoni ta' Sorsi tal-Awdjo
The A70 Pro supports both balanced XLR and single-ended RCA inputs. For optimal performance, use balanced connections when possible.
- Input XLR: Connect your balanced audio source (e.g., DAC) to the XLR input ports on the rear panel.
