Bassoon Sub Woofer Board

Very good sound quality. Excellent deep bass. Stereo input mono output. It is preamp for only Subwoofer. Pros:: 1) Excellent bass frequency control and volume control 2) Adjustable gain setting. 2) Good build quality and durable. Cons:: 1) Requires dual power supply 12 0 12v dc 1A. Power Supply:: 1) Requires rectified 12 0 12v dc 0.5-1A power supply (You need transformer and bridge rectifier for this) 2) Use big capacitor value ( 4700-10000uf) for reducing hiss or humming.

This low pass digital filter (pre amp) is good,but the courier service DTDC is pathetic.The destination address is only few hundred meters from this courier's office but it took more than a month from their delivering date to get delivered. After contacting customer care many times I thought the parcel was lost.Suddenly one day it arrived.Apart from that the product is good.It is fed on both +ve and -ve dc volts like op amp boards,and the power supply circuit is not built in.So after making a power supply circuit (using 7812,7813ic/ google provided all data) I attached it to 12 0 12 .5amp transformer and a power amplifier( tda 7894 ).It sounded great,It also has a frequency tuner which I like . Sound----4/5 Amazon courier service---1/5

Excellent preamp, excellent quality, it will give you a soft and smooth bass by adjusting frequency level, which was not given in many other boards, but remember this is only preamp board, need amplifier for subwoofer, which is essential to get the best bass effect.

Nice bass filter with control bass and frequency.

I use this of subwoofer but I am not getting any sound I don't know why.

best quality but ret high

I BUYED TWICE THIS BOARD, WORKING FINE. WRITING REVIEW AFTER USING MORE THAN SIX MONTHS . STILL WORKING. NICE SUB WOOFER BOARD ,KEEP IT UP . STILL NOT INCREASED PRICE ,SAME PRICE TILL TODAY. VERY HONEST SELLER.
