3. Ρύθμιση
3.1 Αρχική Τοποθέτηση
Position the BR12 loudspeaker in a stable location. The trapezoid design allows for versatile placement, including floor monitoring or stand mounting using the built-in pole socket.
3.2 Σύνδεση πηγών ήχου
The BR12 features two heavy-duty 1/4-inch jacks on its jackplate. These can be used to connect your audio source (e.g., mixer, amplifier) to the loudspeaker. Ensure all connections are secure before powering on your equipment.
3.3 Daisy-Chaining Multiple Loudspeakers
To connect multiple BR12 loudspeakers, use the two 1/4-inch jacks for daisy-chaining. Connect the output of one loudspeaker to the input of the next. Ensure that the total impedance of the connected loudspeakers is compatible with your ampπροδιαγραφές εξόδου του lifier.

4. Λειτουργία
4.1 Ενεργοποίηση/Απενεργοποίηση
Connect the loudspeaker to a suitable power ampσωτηριωτής. Εξασφαλίστε το amplifier's volume is set to minimum before powering on the amplifier and then the loudspeaker. Reverse this order when powering off (loudspeaker first, then ampπιο ζωντανός).
4.2 Ρύθμιση έντασης ήχου
Adjust the volume levels primarily from your mixing console or amplifier. The BR12 has a high sensitivity of 97dB, meaning it can produce significant sound output with relatively low power input. Monitor your amplifier's output levels to prevent clipping or distortion.
4.3 Παρακολούθηση Σήματος
Listen for clear, undistorted sound. If you hear any crackling, buzzing, or harsh sounds, immediately reduce the volume and check all connections. The BR12 is designed for 300W program and 600W peak power handling; exceeding these limits can damage the speaker.

5. Συντήρηση
5.1 Καθαρισμός
Regularly clean the exterior of the loudspeaker with a soft, dry cloth. Avoid using abrasive cleaners, solvents, or excessive moisture, as these can damage the finish or internal components. Keep the steel grille free of dust and debris to ensure optimal sound projection.
5.2 Αποθήκευση
When not in use, store the loudspeaker in a cool, dry environment, away from direct sunlight, extreme temperatures, and high humidity. If transporting, use appropriate protective covers or cases to prevent physical damage.
6. Αντιμετώπιση Προβλημάτων
6.1 Χωρίς ήχο
- Check all power connections to the amplifier and ensure it is powered on.
- Verify that all audio cables (1/4-inch jacks) are securely connected between the source, amplifier, and loudspeaker.
- Ensure the volume levels on your audio source and amplifier are not set to minimum or muted.
- Δοκιμάστε με διαφορετική πηγή ήχου ή καλώδιο για να αποκλείσετε τυχόν ελαττωματικό εξοπλισμό.
6.2 Παραμορφωμένος ήχος
- Reduce the volume level on your audio source and amplifier. Overdriving the input can cause distortion.
- Check for damaged cables or loose connections.
- Εξασφαλίστε το amplifier's output impedance matches the loudspeaker's impedance.
- Avoid exceeding the loudspeaker's power handling capabilities (300W program / 600W peak).
