Setup
- Ħoll il-Komponenti: Carefully remove all items from the packaging and verify that all components listed in "What's in the Box" are present.
- Immuntar (Mhux obbligatorju): If permanent installation is desired, use the provided mounting ears to secure the amplifier in a suitable location. Ensure adequate ventilation around the unit.
- Qabbad l-Ispeakers: 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.
- Qabbad Sorsi Awdjo:
- For stereo audio, connect your source (e.g., media player, computer) to the DĦUL RCA jew il- 3.5mm INPUT fuq il-pannell ta’ wara.
- For a dynamic microphone, connect it to the BALANCE MIC IN 3.5mm input on the rear panel.
- Qabbad il-Kontroll mill-Bogħod (Mhux obbligatorju):
- If using an RS232 control system, connect the control cable to the RS232 blokk terminali.
- If using a standard volume control, connect it to the VOLUM blokk terminali.
- Connect PA System (Optional): If integrating with a public address system, connect the PA signal to the PA IN blokk terminali.
- Konnessjoni tal-Enerġija: 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 se jixgħel.
Importanti: 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.
Istruzzjonijiet Operattivi
- Power On/Off: Il- amplifier powers on automatically when connected to an electrical outlet. There is no physical power button on the unit itself.
- Aġġustament tal-Livelli tal-Input: 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.
- MIC IN: Jaġġusta l-volum għall-input tal-mikrofonu.
Nota: Il- amplifier's mixing function combines all active input signals. Adjust individual levels to achieve the desired audio balance.
- Kontroll tal-Volum tal-Output: 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.
- Swiċċ Mono/Stereo: The "L/MONO" switch on the rear panel allows you to select between stereo output or a summed mono output.
Manutenzjoni
- Tindif: Disconnect power before cleaning. Use a soft, dry cloth to wipe the exterior of the amplifier. Do not use liquid cleaners or aerosols, as they may damage the unit.
- Ventilazzjoni: Tiżgura li l- amplifier's ventilation openings are not blocked. Proper airflow is essential to prevent overheating.
- Ġestjoni tal-Kejbil: Iċċekkja perjodikament il-konnessjonijiet tal-kejbil kollha biex tiżgura li huma sikuri u ħielsa minn ħsara.
- Ħażna: Jekk taħżen il ampJekk tuża l-lifer għal perjodu estiż, skonnettjah mill-elettriku u aħżnu f'post frisk u niexef 'il bogħod mix-xemx diretta u minn temperaturi estremi.
