• Interruttore di alimentazione: Attiva o disattiva il ampacceso/spento.
• Controlli del livello di ingresso: Rotary knobs for adjusting the input sensitivity of Channel 1 and Channel 2.
• Indicatori LED:
  • Energia: Si illumina quando l'unità è accesa.
  • Limitatore: Indicates when the built-in limiter is active to prevent clipping.
  • segnale: Shows the presence and level of the input audio signal (-20 dB, -10 dB, -5 dB, 0 dB).

Pannello posteriore

• Connettori di ingresso: XLR and 1/4" TRS balanced inputs for Channel 1 and Channel 2.
• Input Thru: XLR output for daisy-chaining the input signal to another amppiù vivace.
• Connettori di uscita: Binding posts and Speakon connectors for connecting loudspeakers for Channel 1 and Channel 2.
• Interruttore di modalità: Selects between NORMAL (dual mono), STEREO, and BRIDGE operating modes.
• Filtro taglia-basso: Switches to activate a low-cut filter (e.g., 20Hz, 200Hz) for each channel.
• Input Balance/Sensitivity DIP Switches: Allows adjustment of input sensitivity (e.g., 0 dB, -3 dB, -6 dB, -12 dB).
• Interruttore di sollevamento a terra: Helps eliminate hum by disconnecting the signal ground from the chassis ground.
• Ingresso di alimentazione CA: Standard IEC power connector for the main power cable.
• Portafusibili: Contains the main protective fuse (F 15A 250V).

Impostare

1. Posizionamento: Posizionare il amplifier in a well-ventilated area, away from direct heat sources. Ensure it is securely mounted if rack-mounted.
2. Spegni: Assicurare il amplifier's power switch is in the OFF position before making any connections.
3. Connessioni di ingresso: Collega la tua sorgente audio (mixer, preamplifier) to the XLR or 1/4" TRS input connectors on the rear panel for Channel 1 and Channel 2.
4. Connessioni di uscita: Connect your loudspeakers to the appropriate output connectors (Speakon or binding posts). Ensure correct polarity (+ to +, - to -).
5. Selezione della modalità: Set the MODE switch on the rear panel to STEREO for two separate channels, NORMAL for dual mono, or BRIDGE for mono operation with increased power. Refer to your speaker impedance for bridge mode compatibility.
6. Filtro taglia-basso: If desired, engage the low-cut filter switches to remove unwanted low frequencies.
7. Collegamento elettrico: Collegare il cavo di alimentazione CA in dotazione al amplifier's AC inlet and then to a grounded power outlet.

Operativo

1. Accensione iniziale: Turn on your audio source first, then switch the amplifier's power to ON.
2. Regolazione del volume: Start with the input level controls on the front panel set to minimum. Gradually increase them to achieve the desired output volume.
3. Indicatori di monitoraggio: Observe the SIGNAL LEDs to ensure a healthy input signal. The LIMITER LEDs should only flash occasionally during peak signals. If they are constantly lit, reduce the input level to prevent distortion and potential speaker damage.
4. Spegni: Al termine, spegnere il amplifier first, then your audio source.

Manutenzione

• Pulizia: Utilizzare un panno morbido e asciutto per pulire la parte esterna del amplificatore. Non utilizzare detergenti liquidi o solventi.
• Ventilazione: Regularly check that the ventilation grilles are free from dust and debris to ensure proper airflow.
• Sostituzione fusibile: Se il amplifier does not power on, check the fuse in the rear panel. Replace it only with a fuse of the same type and rating (F 15A 250V).
• Magazzinaggio: Se si memorizza il amplificatore per un periodo prolungato, assicurarsi che sia in un ambiente asciutto e privo di polvere.
