4.2 Connectar altaveus
- Assegureu-vos el ampl'amplificador està apagat i desendollat de la presa de corrent.
- 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 (-).
- For optimal sound, use high-quality speaker cables.
4.3 Connexió de fonts d'àudio
- 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.
- Connect a tuner to the TUNER input jacks.
- Connect other audio devices (e.g., CD player, cassette deck) to the AUX input jacks.
- 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 preamplificador i poder amplifier sections. To use an external preamplifier o poder 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. Instruccions de funcionament
