hi guys

GONG XI FAT CHAI to all that celebrate it.. success always!!

i am new to this forum. just got the pcb for arjen. just wondering if you guys have the schematic? smd desoldering and soldering is killing me. just wanna try to find alternative for soldering thx. with this pcb i would try to run a full range with 85db sensitivity. finger cross that it will be able to drive it lol...

heard you guys has success with car audio setup. this thing come to mind as well. as it draw same voltage as the car battery. just confirmation. this pcb need 0v and 12vdc right?

can we use -6vdc for the (ground) and +6vdc for the (+12v)?

anyway my car speaker is boston pro acoustic 6.53 with spec below: can this lil t-amp drive it?

help!!

i connect the stock module. nothing being change. the dc at the speaker terminals are 60mv and 17mv. is this safe to connect the speaker?

the unit it only power up with 12vdc and has not been connected to anything..

how to lower the dc? thx in adv

hi xtorm

me from indonesia. neighboring country. yesp ta2024 looks good with my existing 85db 2 way speakers. it plays quite loud. could shake the house. will try the dc offset mod to zero and other discrete components. maybe give the arjen board few days. as it clear up quite nicely in upper register. nice nice.

on other forum, a user seems to prefer ta2020 such as charlize over the ta2024. how do you guys find?

nice touch. is that the aluminium case? where do you get it? i saw one guys sell it on ebay, been thinking bout that but havent pull the trigger

hi guys

i am using 3A regulated ic power supply. sound not bad. just wondering if the meanwell smps going to be better investment? found in ebay sell for usd$39 for 12v 12A. bit overkill. just wondering how much you got this locally?

there is "Rayed" brand, for only usd $17 for the 5A. just wondering if you guys have any experience on this? thx

one more thing, does the ouput ground of the meanwell smps connected to the main earth and chassis? as i am considering another application that output +24vdc 0v -24vdc by using 2 smps module. thx in adv

bsl555, nice... thanks

jazzy939, i need +24v 0v -24v for gc. just wanna play around. if the meanwell smps cant disconnect the output ground from the earth input, the 2 smps cant be joined to get the negative voltage. i am planning to get 2 smps with 24 v for GC (which still in consideration) and 1 smps with 12v for t-amp.

any experience with the "Reyed" smps? only cost half of the main well..

meanwell $33

reyed $17

all include shipping. how much do you pay for the meanwell in ringgit?

hi jazzy, geez thats cheap. wish i can buy there

bsl555, too bad i am in indonesia. will shop there when i visit pasar rd. kl is it?

resounding YES!! i had doubt before as well, but was shock when i connect them to the speaker. superb. my speaker diy.. rated 83db. but it sound louder than my spendor s3/5 which is rated at 83db as well.
