Subwoofer Channel System

Subwoofer Channel system

Car subwoofer With the growth of domestic car ownership and the rapid development of automotive supplies industry, more and more into the music owners of many car music. So, in the face of just access to the car subwoofer, many owners in addition to fascinating its music super shock, but also distressed in the existing lack of knowledge and can not start their own hands, can not meet the pursuit of car music. Then here will be popular, is the car subwoofer with the debugging and debugging.

First, strengthen the 2-channel system bass connection

(1) Connect the left and right signals of the audio source (CD or DVD player) into the left and right signal input of the gun, and then the signal output of the new gun is connected to the power amplifier. The signal is driven by the amplifier. The

Connection 2: If the source has 2 sets of signal output or 1 minute 2 signal lines, one group of access guns, another set of access power amplifier.

Gun debugging: frequency of visual noise to adjust the caliber, caliber, can be minimized, while the increase, depending on personal preferences, there is no uniform standard. Phase switch which bass good election in that position, the volume with the main speaker with. , Assume 5.1 system of 0.1-channel subwoofer amplification

Connection 1: AV amplifier with decoding has a subwoofer signal output, with a gun (preferably a penny of the two) the amplifier's subwoofer output signal into the gun, the frequency of the gun Can be adjusted as much as possible, the volume is also adjustable, because the signal by the AV amplifier limit, the operation is also convenient.

Connection 2: with the decoding of the DVD machine also has a subwoofer signal output, with a gun (preferably a penny of the two) to the DVD player's subwoofer output signal into the gun, using this gun Frequency and volume attention to the main speaker and the center with the surrounding. The general frequency is set at 12 o'clock position, the volume is adjusted at 3 o'clock position, but there is no uniform standard.

Feeling: active subwoofer is a sound system is easy to be overlooked part of the gun itself is a separate equipment, but also with other speakers to match the sound, the sound of the gun is transferred out, to be a good voice, to Have patience. Subwoofer and speaker work is exactly the same, but the diaphragm diameter is larger, generally 8 to 10 inches, and increased for the resonance of the speaker.

Evaluation indicators, the subwoofer with the speaker is basically the same, the specific content here is not specifically introduced, only talk about the numerical requirements, the frequency response is generally below 200 Hz, the rated impedance is about 4Ω, the sensitivity is generally greater than 90 dB / W / m.
