Configurar
- Descompacte os componentes: Carefully remove all items from the packaging and verify that all components listed in "What's in the Box" are present.
- Montagem (Opcional): If permanent installation is desired, use the provided mounting ears to secure the amplifier in a suitable location. Ensure adequate ventilation around the unit.
- Conectar alto-falantes: 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.
- Conecte fontes de áudio:
- For stereo audio, connect your source (e.g., media player, computer) to the ENTRADA RCA ou o ENTRADA DE 3.5 mm no painel traseiro.
- For a dynamic microphone, connect it to the BALANCE MIC IN 3.5mm input on the rear panel.
- Connect Remote Control (Optional):
- If using an RS232 control system, connect the control cable to the RS232 bloco terminal.
- If using a standard volume control, connect it to the VOLUME bloco terminal.
- Connect PA System (Optional): If integrating with a public address system, connect the PA signal to the PA IN bloco terminal.
- Conexão de energia: 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 será ligado.
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.
Instruções de operação
- Ligar/desligar: O amplifier powers on automatically when connected to an electrical outlet. There is no physical power button on the unit itself.
- Adjusting Input Levels: 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.
- 3.5 mm: Adjusts the volume for the 3.5mm stereo input.
- MIC ENTRADA: Adjusts the volume for the microphone input.
Nota: O amplifier's mixing function combines all active input signals. Adjust individual levels to achieve the desired audio balance.
- Controle de volume de saída: The overall output volume can be controlled via the connected remote wired wall plate controller or RS232 system, if installed.
- Sensibilidade da página: 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.
- Chave mono/estéreo: The "L/MONO" switch on the rear panel allows you to select between stereo output or a summed mono output.
Manutenção
- Limpeza: 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.
- Ventilação: Assegurar que o ampAs aberturas de ventilação do amplificador não estão bloqueadas. O fluxo de ar adequado é essencial para evitar o superaquecimento.
- Gerenciamento de cabos: Verifique periodicamente todas as conexões de cabos para garantir que estejam seguras e sem danos.
- Armazenar: Se armazenar o amplifier for an extended period, disconnect it from power and store it in a cool, dry place away from direct sunlight and extreme temperatures.
