【 Weak current College 】 phase and time delay adjustment---Power By 【 China power house network 】

You may find that the adjustment phase settings (usually in the woofer speaker adjustment, if necessary, can also be adjusted on the decoder) will cause the primary speaker/sub woofer speaker integrated sound more balanced. Test will immediately display is improved: you can be in a certain phase to hear more or fewer low-frequency. Change the phase you hear listening room acoustics sound effects arising both sides, so that you are listening to the location of the sound effects will be different. To carry out phase adjustment, you must clear this would bring joys and half results.

Like I said before, you sit in a listening area where the audition of different, let your assistant to adjust a woofer speaker phase (the other one is closed), audition repeatedly until you get the best sound. Then another woofer speaker for the same test, you must first turn off the speakers. Finally, two woofer speakers are turned on, if necessary and then they are more adjustment, you will find this process using a different test software would be more helpful.

Despite the delay adjustment for different purposes, I still use it with phase adjustment back together, because when you adjust the delay parameter, you can also change the phase. Delay can be regarded as a system to display the sub woofer speaker or reduce the woofer speaker signal routing differences between electronic method.
Delay adjustment to different objectives for the professional audio and home audio fields are frequently used. Some people find ignored phase settings, put the effort in the delay would be better organised. In the woofer speaker sound effects of the integration process, the delay can be used to make from the woofer speaker and main speakers at the arrival of direct sound to hear. Know the speed of the voice, you can quickly figure out a variety of positioning mode signal transmission distance of difference (so even if the delay of many), but how do you figure out the figure number 39aof delay?
For this particular situation, suppose front woofer speaker and friendly speaker of a substantial mode enables its audio at the same time get to listen to the location. Calculation of sound from the left, Center, right, and the former woofer speakers to listen to the location of the time (in ms) or distance (in feet or metres). Then calculate the rear woofer speaker delay.

For example, suppose your left and right, in front of the main speaker/subwoofer speakers from the listening position 5 meters, while the rear left overload listen subwoof position 1 m, 5m – 1m = 4m. Therefore you need to make the rear woofer speaker 4m delay. In this way, from the main left and right, front woofer in/sound and rear woofer speaker sound can also reach the listening position.
