Утас
The 512E-D4 features a Dual 4-Ohm voice coil configuration. Proper wiring is essential to match the impedance requirements of your ampөргөгч. Зөвлөгөө аваарай ampТохиромжтой эсэргүүцэлтэй ачааллын өргөлтийн гарын авлага.
Common wiring configurations for dual voice coil subwoofers:
- Series Wiring (for a single subwoofer): Connect the positive terminal of one voice coil to the negative terminal of the other voice coil. The remaining positive and negative terminals will present an 8-Ohm load.
- Parallel Wiring (for a single subwoofer): Connect both positive terminals together and both negative terminals together. This will present a 2-Ohm load.
- Олон сабвуфер: When using multiple subwoofers, further series or parallel connections can be made to achieve the desired final impedance. Always ensure the final impedance matches your ampөргөгч төхөөрөмжийн тогтвортой ажиллах хүрээ.
