2. Istruzioni di sicurezza

To prevent fire, electric shock, and damage to the unit, please observe the following safety precautions:

• Fonte di energia: Connect the unit only to an AC 100V, 50/60Hz power supply.
• Ventilazione: Ensure adequate ventilation. Do not block ventilation openings on the top or sides of the unit. Maintain at least 10 cm (4 inches) clearance around the unit.
• Acqua e umidità: Non esporre l'unità a pioggia o umidità. Non posizionare oggetti contenenti liquidi, come vasi, sull'unità.
• Fonti di calore: Tenere l'unità lontana da fonti di calore quali termosifoni, bocchette di ventilazione, stufe o altri apparecchi che producono calore.
• Pulizia: Scollegare l'unità dalla presa a muro prima di pulirla. Utilizzare solo un panno asciutto.
• Manutenzione: Non tentare di riparare l'unità da soli. Per qualsiasi intervento di assistenza, rivolgersi a personale qualificato.

• Power/Protector Indicator: Lights red when power is on. Flashes or turns off if the protection circuit is activated.
• Speakers Selector: Selects speaker outputs A, B, A+B, or Off.
• Controllo degli acuti: Regola la risposta alle alte frequenze.
• Controllo dei bassi: Regola la risposta alle basse frequenze.
• Interruttore di alimentazione: Gira il amplificatore acceso o spento.
• Jack per telefoni: Per il collegamento di cuffie stereo.
• Tone Defeat Switch: Bypasses the Bass and Treble controls for a flat frequency response.
• Interruttore del filtro subsonico: Activates a filter to cut ultra-low frequencies below 16Hz, which can cause speaker cone flutter.
• Interruttore di volume: Engages loudness compensation for enhanced bass and treble at low volume levels.

3.2 Front Panel Controls (Right Side)

• Controllo del volume: Adjusts the overall sound level. This is a low-error 2-gang detent volume control.
• Controllo dell'equilibrio: Regola il volume relativo tra i canali sinistro e destro.
• Selettore di ingresso: Selects the desired audio source (Phono-1, Phono-2, Tuner, AUX).
• Tape Play Selector: Selects the source for tape playback (Source, Tape-1, Tape-2).
• Copy Selector: Used for dubbing between tape decks (Off, 1→2, 2→1).

3.3 Collegamenti del pannello posteriore

• Terminali di ingresso: RCA jacks for Phono (1 & 2), Tuner, and AUX sources.
• Tape Input/Output Terminals: RCA jacks for connecting Tape Deck 1 and Tape Deck 2.
• Pre Out / Main In Terminals: RCA jacks for separating the preamplificatore e potere amplifier sections. These are connected by removable jumpers for normal operation.
• Terminali altoparlanti: Connect your speakers to System A and/or System B.
• AC Outlets (Switched/Unswitched): For connecting other audio components to draw power from the amppiù vivace.
• Terminale di terra (GND): For connecting the ground wire from a turntable.

4. Impostazione

4.1 Posizionamento

Posizionare il amplifier on a stable, level surface. Ensure there is sufficient space around the unit for proper ventilation. Avoid placing it near heat sources or in direct sunlight.

4.2 Collegamento degli altoparlanti

1. Assicurare il amplifier è spento e scollegato dalla presa di corrente.
2. Connect your speakers to the SPEAKER A or SPEAKER B terminals on the rear panel. Match the positive (+) terminal of the speaker to the positive (+) terminal of the amplifier, and the negative (-) to the negative (-).
3. For optimal sound, use high-quality speaker cables.

4.3 Collegamento delle sorgenti audio

1. Connect your turntable to the PHONO 1 or PHONO 2 input jacks. If your turntable has a ground wire, connect it to the GND terminal.
2. Connect a tuner to the TUNER input jacks.
3. Connect other audio devices (e.g., CD player, cassette deck) to the AUX input jacks.
4. For tape recording and playback, connect your tape decks to the TAPE 1 and TAPE 2 REC/PLAY jacks.

4.4 Pre-Main Separation

The AU-607 allows for separation of its preamplificatore e potere amplifier sections. To use an external preamplificatore o potere amplifier, remove the jumpers connecting the PRE OUT and MAIN IN terminals on the rear panel. Connect your external preamplifier to the MAIN IN terminals or your external power amplifier to the PRE OUT terminals.

5. Istruzioni per l'uso

1. Accensione: Ensure all connections are secure. Plug the power cord into an AC outlet. Press the POWER switch on the front panel. The Power/Protector indicator will light red.
2. Selezione degli altoparlanti: Use the SPEAKERS selector to choose your desired speaker system (A, B, or A+B). Select 'Off' when using headphones only.
3. Selezione input: Turn the INPUT SELECTOR knob to choose the audio source you wish to listen to (Phono-1, Phono-2, Tuner, AUX).
4. Regolazione del volume: Slowly turn the VOLUME knob clockwise to increase the sound level. Adjust to a comfortable listening level.
5. Controlli di tono: Use the BASS and TREBLE knobs to adjust the low and high frequencies to your preference. For a flat frequency response, engage the TONE DEFEAT switch.
6. Regolazione del bilanciamento: Use the BALANCE knob to adjust the sound distribution between the left and right channels.
7. Filtro subsonico: If you hear unwanted low-frequency rumble or notice excessive speaker cone movement, engage the SUBSONIC FILTER switch.
8. Loudness: For listening at low volume levels, engage the LOUDNESS switch to enhance bass and treble.
9. Tape Functions: Use the TAPE PLAY selector to listen to a connected tape deck. Use the COPY selector for dubbing between two tape decks.
10. Spegni: Press the POWER switch again to turn off the amppiù vivace.

6. Manutenzione

• Pulizia: Pulire regolarmente l'unità con un panno morbido e asciutto. Non utilizzare detergenti abrasivi, cere o solventi.
