The front panel provides access to essential controls and indicators for real-time operation:

• Interruttore di alimentazione: Toggles the unit's power on/off.
• Input Volume Control Knobs (x4): Adjust the individual volume levels for each of the four input channels.
• Bass Controls (x4): Adjust the low-frequency response for each input channel.
• Treble Controls (x4): Adjust the high-frequency response for each input channel.
• Output Volume Control Knob (Master): Controls the overall output volume of the mixer-amppiù vivace.
• Signal Indicators (Green LEDs): Illuminate to indicate the presence of an audio signal on each input and the main output.
• Clip Indicator (Red LED): Illuminates when the output signal is clipping, indicating potential distortion.
• Power Indicator (Blue LED): Si illumina quando l'unità è accesa.

4. Impostazione

Follow these steps to set up your Crown 1160MA Mixer-Amplificatore:

1. Posizionamento: Place the unit on a stable, flat surface or mount it in a standard 19-inch equipment rack. Ensure adequate ventilation around the unit.
2. Collegamento elettrico: Ensure the power switch on the front panel is in the OFF position. Connect the supplied AC power cord to the AC Power Inlet on the rear panel and then to a suitable mains power outlet.
3. Connessioni di ingresso:
   • For microphones or balanced line-level sources, use the 3-pin Phoenix Input Connectors.
   • For unbalanced stereo sources (e.g., CD players, media players), use the RCA Stereo Input Pairs.
   • Set the corresponding Mic/Line Selector Switches on the rear panel to the appropriate setting (MIC for microphones, LINE for line-level sources).
   • If using condenser microphones, enable Phantom Power via the Mixer Config. DIP Switch on the rear panel for the respective channel.
4. Connessione di uscita: Connetti il ​​tuo amplifier or powered speakers to the 3-Pin Balanced Phoenix Output Connector on the rear panel.
5. Connessioni opzionali: Connect 24VDC backup power or a priority muting system if required, following the specific instructions for those systems.
6. Impostazioni iniziali: Before powering on, set all Input Volume, Bass, Treble, and Master Output Volume controls to their minimum (fully counter-clockwise) positions.

5. Istruzioni per l'uso

Una volta configurata l'unità, seguire questi passaggi per il funzionamento:

1. Accensione: Flip the Power Switch on the front panel to the ON position. The blue Power Indicator LED will illuminate.
2. Regola i livelli di input: Slowly increase the Input Volume Control Knob for the desired input channel. Observe the green Signal Indicator LED; it should illuminate consistently with the audio signal. If the red Clip Indicator LED flashes, reduce the input volume to prevent distortion.
3. Regolazione del tono: Use the Bass and Treble Controls for each input to fine-tune the low and high frequencies of that specific source. The Output Tone Control Potentiometer on the rear panel provides overall tone adjustment for the main output.
4. Livello di uscita principale: Gradually increase the Master Output Volume Control Knob to achieve the desired overall sound level from your speakers. Again, monitor the Clip Indicator LED to avoid distortion.
5. Muting prioritario: If configured, the priority muting feature will automatically attenuate other audio signals when a designated priority source (e.g., a paging microphone) is active.
6. Monitoraggio: Continuously monitor the Signal and Clip Indicator LEDs during operation to ensure optimal signal levels and prevent clipping.

6. Manutenzione

Regular maintenance ensures the longevity and reliable performance of your mixer-amplificatore:

• Pulizia: Disconnect the unit from power before cleaning. Use a soft, dry cloth to wipe down the exterior. Do not use liquid cleaners or solvents.
• Ventilazione: Periodically check that the ventilation openings are clear of dust and debris. Use a soft brush or compressed air to gently remove any accumulation.
• Connessioni: Occasionally check all cable connections for secure fit. Loose connections can lead to signal loss or intermittent performance.
• Magazzinaggio: If storing the unit for an extended period, ensure it is in a dry, cool environment, away from direct sunlight and extreme temperatures.
