2. Guida all'installazione
Before operating your Behringer 676, please follow these setup instructions carefully to ensure proper functionality and safety.
2.1 Disimballaggio
- Rimuovere con attenzione l'unità dalla confezione.
- Inspect the unit for any signs of damage during transit. If damage is found, contact your dealer immediately.
- Conservare l'imballaggio originale per eventuali trasporti o immagazzinamenti futuri.
2.2 Connessioni
Prima di effettuare qualsiasi collegamento, assicurarsi che l'unità sia spenta.
- Ingresso audio: Connect your microphone, instrument (e.g., guitar), or line-level source to the appropriate input jacks on the rear panel. The front panel offers HI-Z input for instruments.
- Uscita audio: Connect the main output of the 676 to your audio interface, mixer, or power amplifier using balanced XLR or TRS cables.
- Energia: Connect the supplied AC power cable to the unit's power inlet and then to a suitable AC power outlet.
3. Istruzioni per l'uso
This section details the functions of the front panel controls for the Behringer 676.
3.1 preamplifier Section (Left Panel)
- Manopola GAIN: Adjusts the input gain from -10 A +10. Use this to set the initial signal level.
- Input Select Switches: Selects the input type.
- MICROFONO: For microphone inputs (impedance options: 500, 2.0K).
- LINEA: For line-level inputs (impedance: 47K).
- HI-Z: For high-impedance instruments like guitars (impedance: 2.2 milioni).
- Interruttore pad: Engages a -15 dB attenuation pad for hot input signals.
- OUT Ø / IN Ø Switches: Controls the phase of the output signal. OUT Ø inverts the phase, IN Ø maintains normal phase.
- Manopola LIVELLO: Adjusts the output level of the preamplifier section from 0 A 10.
3.2 Equalizer Section (Middle-Left Panel)
- Manopola ALTA: Boosts or cuts high frequencies from -9 A +9. Selectable frequencies include 4.5K, 7K, E 10K.
- Manopola LOW: Boosts or cuts low frequencies from -9 A +9. Selectable frequencies include 70, 100, E 200.
3.3 Limiting Amplifier Section (Right Panel)
- Manopola ATTACCO: Adjusts the time it takes for the compressor to react to signals above the threshold, from LENTO A VELOCE.
- RELEASE Knob: Adjusts the time it takes for the compressor to return to its normal state after the signal falls below the threshold, from LENTO A VELOCE.
- Manopola INPUT: Controls the signal level entering the compressor from 0 A 10.
- Manopola OUTPUT: Controls the final output level of the limiting amplificatore da 0 A 10.
- METER Switch: Selects what the VU meter displays:
- PRE: Input level before compression.
- GR: Gain Reduction (amount of compression applied).
- COMPONENTE: Output level after compression.
- Manopola RAPPORTO: Sets the compression ratio, from 1 (no compression) to TUTTO (limiting). Other options include 4, 8, 12, 20.
- Misuratore VU: Displays the selected signal level or gain reduction.
3.4 Global Controls (Middle Panel)
- JOIN/SPLIT Switch: Determines if the preamplifier and limiting amplifier sections operate independently (DIVISO) or as a combined unit (GIUNTURA).
- ON/48 V Switch: Activates the unit's power (ON) and provides 48 Volt phantom power for condenser microphones.
- Interruttore di ALIMENTAZIONE: Accende o spegne l'unità.
4. Manutenzione
Proper maintenance ensures the longevity and optimal performance of your Behringer 676.
- Pulizia: Utilizzare un panno morbido e asciutto per pulire l'esterno dell'unità. Evitare detergenti abrasivi o solventi.
- Ventilazione: Assicurare un'adeguata ventilazione attorno all'unità per evitare il surriscaldamento. Non ostruire le aperture di ventilazione.
- Magazzinaggio: When not in use for extended periods, store the unit in a cool, dry place, preferably in its original packaging.
- Sostituzione del tubo: The vacuum tube inside the unit has a finite lifespan. If you notice a degradation in sound quality, consult a qualified technician for tube replacement.
