Impostare
- Disimballare i componenti: Carefully remove all items from the packaging and verify that all components listed in "What's in the Box" are present.
- Montaggio (facoltativo): If permanent installation is desired, use the provided mounting ears to secure the amplifier in a suitable location. Ensure adequate ventilation around the unit.
- Collegare gli altoparlanti: Connect your 25V or 70V speakers to the "SPEAKER OUTPUTS" terminals on the rear of the amplifier using appropriate speaker wire. Ensure correct polarity (+ to + and - to -). The amplifier provides 25 watts per channel.
- Collegare le sorgenti audio:
- For stereo audio, connect your source (e.g., media player, computer) to the INGRESSO RCA o il INGRESSO 3.5 mm sul pannello posteriore.
- For a dynamic microphone, connect it to the BALANCE MIC IN 3.5mm input on the rear panel.
- Collegamento del telecomando (facoltativo):
- If using an RS232 control system, connect the control cable to the RS232 blocco terminale.
- If using a standard volume control, connect it to the VOLUME blocco terminale.
- Connect PA System (Optional): If integrating with a public address system, connect the PA signal to the PA IN blocco terminale.
- Collegamento elettrico: Connect the AC adapter to the "DC IN" port on the amplifier and then plug the AC power cord into a standard electrical outlet. The amplifier si accenderà.
Importante: Ensure all connections are secure before powering on the unit. Refer to the wiring diagrams for specific terminal block connections if available in supplementary documentation.
Istruzioni per l'uso
- Accensione/spegnimento: IL amplifier powers on automatically when connected to an electrical outlet. There is no physical power button on the unit itself.
- Regolazione dei livelli di ingresso: Use the dedicated knobs on the front panel to adjust the input levels for RCA, 3.5mm, and MIC IN sources.
- RCA: Adjusts the volume for the RCA stereo input.
- 3.5mm: Adjusts the volume for the 3.5mm stereo input.
- INGRESSO MICROFONO: Adjusts the volume for the microphone input.
Nota: Il amplifier's mixing function combines all active input signals. Adjust individual levels to achieve the desired audio balance.
- Controllo del volume in uscita: The overall output volume can be controlled via the connected remote wired wall plate controller or RS232 system, if installed.
- Page Sensitivity: The "PAGE SENSITIVITY" switch on the rear panel adjusts the sensitivity of the PA sensor. This determines how readily the amplifier mutes other audio when a public address signal is present. Adjust as needed for your PA system.
- Interruttore mono/stereo: The "L/MONO" switch on the rear panel allows you to select between stereo output or a summed mono output.
Manutenzione
- Pulizia: Scollegare l'alimentazione prima della pulizia. Utilizzare un panno morbido e asciutto per pulire l'esterno dell'apparecchio. amplifier. Do not use liquid cleaners or aerosols, as they may damage the unit.
- Ventilazione: Assicurarsi che il ampLe aperture di ventilazione del lificatore non siano ostruite. Un corretto flusso d'aria è essenziale per evitare il surriscaldamento.
- Gestione dei cavi: Controllare periodicamente tutti i collegamenti dei cavi per assicurarsi che siano saldi e privi di danni.
- Magazzinaggio: Se si memorizza il amplifier per un periodo prolungato, scollegarlo dall'alimentazione e conservarlo in un luogo fresco e asciutto, lontano dalla luce solare diretta e da temperature estreme.
Risoluzione dei problemi
