- If using a standard volume control, connect it to the Iwọn didun Àkọsílẹ ebute.
- Connect PA System (Optional): If integrating with a public address system, connect the PA signal to the PA IN Àkọsílẹ ebute.
- Asopọ agbara: 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 yoo agbara lori.
Pataki: 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.
Awọn ilana Iṣiṣẹ
- Titan/Apapa: Awọn amplifier powers on automatically when connected to an electrical outlet. There is no physical power button on the unit itself.
- Ṣíṣe àtúnṣe Àwọn Ìpele Ìwọlé: 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 NI: Adjusts the volume for the microphone input.
Akiyesi: Awọn amplifier's mixing function combines all active input signals. Adjust individual levels to achieve the desired audio balance.
- Iṣakoso Iwọn didun Ijade: The overall output volume can be controlled via the connected remote wired wall plate controller or RS232 system, if installed.
- Ifamọ oju-iwe: 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.
- Mono/Stẹrio Yipada: The "L/MONO" switch on the rear panel allows you to select between stereo output or a summed mono output.
