3.4 Connexió de sortides
El amplifier provides multiple output options:
- Speakon Connectors (x2): For connecting loudspeakers using Speakon cables. These are typically used for high-power connections.
- Binding Post Connectors (x2 pair): For connecting loudspeakers using bare wire or banana plugs. Ensure correct polarity (+/-).
- XLR Link/Out (x2): For daisy-chaining the audio signal to other amplificadors o dispositius.
Ensure that the impedance of your loudspeakers matches the amplifier's capabilities (2Ω, 4Ω, or 8Ω).
3.5 Connexió d'alimentació
Connecteu el cable d'alimentació subministrat a la amplifier's AC inlet and then to a suitable grounded power outlet. The XTi2002 features a locking power cord clip to ensure a secure connection, preventing accidental disconnections.
4. Funcionament del Ampmés viu
4.1 Controls i indicadors del tauler frontal
El panell frontal proporciona accés a tots els controls i funcions de monitorització essencials:
- Botons de nivell d'entrada: Ajusteu la sensibilitat d'entrada per a cada canal.
- Pantalla LCD: Shows operational status, menu navigation, and parameter settings.
- Botons de menú: Navegueu per la amplifier's internal menus for DSP settings, fan modes, and system monitoring.
- Indicadors:
- Senyal: S'il·lumina quan hi ha un senyal d'àudio.
