5.2 Wiring and Impedance Selection
The MB1224 features selectable impedance (2 Ohm or 4 Ohm) using the included jumper cables. This allows you to configure the subwoofer to match your amplifier's capabilities. Always ensure your amplifier is stable at the selected impedance.
5.2.1 4 Ohm Wiring Configuration
To configure the subwoofer for a 4 Ohm load, connect the included jumper cable between the two positive terminals and another jumper cable between the two negative terminals. Then, connect your amplifier's positive output to one of the positive terminals and the amplifier's negative output to one of the negative terminals. Refer to Figure 3 for a visual guide.

5.2.2 2 Ohm Wiring Configuration
To configure the subwoofer for a 2 Ohm load, connect the included jumper cable from the positive terminal of one voice coil to the negative terminal of the other voice coil. Then, connect your amplifier's positive output to the remaining positive terminal and the amplifier's negative output to the remaining negative terminal. Refer to Figure 4 for a visual guide.

6. Funtzionamendu-argibideak
6.1 Hasierako Aldia
Subwooferra bolumen altuan erabili aurretik, utzi 10-20 ordu inguruko entzute normala erabiltzen hasteko. Horrela, esekiduraren osagaiak askatu eta errendimendu optimoa lortuko da.
6.2 Amplifier Ezarpenak
Zure behar bezala ezartzea amplifier's gain, crossover, and bass boost is critical. Start with the gain at its lowest setting and slowly increase it until you achieve the desired volume without distortion. Set the low-pass filter (LPF) on your amplifier to prevent high frequencies from reaching the subwoofer, typically between 80Hz and 120Hz. Avoid excessive bass boost, as this can lead to distortion and potential damage.
7. Mantentzea
The Memphis Audio MB1224 subwoofer requires minimal maintenance:
- Periodically inspect the subwoofer cone and surround for any signs of damage or wear.
- Ziurtatu kableatu-konexio guztiak ondo finkatuta daudela eta korrosiorik gabe daudela.
- Clean the subwoofer's exterior with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Keep the subwoofer free from dust and debris, especially if it is not enclosed.
8. Arazoak
Subwooferrarekin arazoak badituzu, jo ezazu honako arazo eta irtenbide ohikoenei:
| Arazoa | Kausa posiblea | Irtenbidea |
