YLY2088 Double 2 Way 400W Adjustment Treblebfrequency

Specifications: Model: YLY-2088 Size: 7 x 5 x 2.5cm Power: 400W or lower Resistance: 4-16 Frequency: Adjustable With 4 jumpers onboard to optimize your audio effect: Jumper A, B for ba; Jumper C, D for treble (for setting details, please see below). Details about jumpers: Jumper A, B are used to control audio effect of ba range. A for lower limit while B for upper limit of the ba audio range. For some speakers, when Ba is turned up too much, the speaker will show distortion. When that happens: we remove the jumper cap of jumper A to limit super low Ba to bring distortion lower. When we remove the cap of jumper B, Ba is increased while cap of Jumper B is on, Ba is decreased. Jumper C and D are used to control Treble range. When cap of both jumper C and D are on, the sound of treble is loudest. When only cap C is on, the treble sound is lower. When only cap D is on, further lower. When both caps of C and D are removed, there is no treble sound. (Generally speaking, with the four jumpers, you'd sooner or later find your best sound effect. Anywya, all effects still depend on your actual test.) How to use the splitter board: First connect as per our diagram above (Treble, Low, Input), connect to speaker, seal air gap, we can begin to hear music while optimize. Normally we use jumper A and let B idle. For jumper C and D: we need to hear the actual effect of treble. A general formula is: A+D = better Ba; A+C = clear Treble and Ba; A+CD = clear Treble and Ba (the overall effect inclined towards Treble); AB+CD = more mediant frequency. When Ba effect is unnecearily high, we can remove cap A. Please optimize until you think the sound is best, and then fix the board with your speaker unit. Package includes: Audio Speaker Frequency Divider
