The perfect achieve setting will range relying on the amplifier, audio system, and subwoofer, however a superb start line is to set the achieve to about three-quarters of its most worth.
Crossover
The crossover is a filter that divides the audio sign into two frequency ranges. The low-pass filter sends the low frequencies to the subwoofer, whereas the high-pass filter sends the excessive frequencies to the audio system. The crossover frequency needs to be set to some extent the place the subwoofer and audio system can seamlessly mix collectively.
Section
The part of the sign is a measure of its timing. If the part of the sign is just not right, the subwoofer and audio system can cancel one another out. The part setting needs to be set to 0 levels or 180 levels, relying on the amplifier and subwoofer.
EQ
The EQ (equalizer) is a filter that permits you to modify the frequency response of the amplifier. This can be utilized to right for any imbalances within the audio system or subwoofer. The EQ settings will range relying in your private preferences and the acoustics of your room.
Degree
The extent is a measure of how loud the amplifier is. The extent needs to be set to a snug listening stage. Too low and you will not be capable of hear the music. Too loud and you might injury your audio system or listening to.
| Parameter | Description |
|---|---|
| Achieve | Boosts the audio sign |
