Lasonic I931-BTQ mod

[TMR]

ok.. well i grabbed one of these when they came out a couple months ago.. turned it on and EEEWWW it sounded like shiznit.. like it was over loaded with sound.. this is the first i931 i purchased.. and i heard they sound not so good.. but i didnt expect it to sound this crappy.. and on top of crappy sound.. the SD/MMC slot wasnt working.. i was mega pissed.. and i could have just returned it.. but i hate going through the PayPal process and having to ship it back.. just didnt want to deal with it.. i almost just tossed it in the trash i was so pissed.. well i put it in my closet for a few months.. and i am on vacation so i figured i'd tear it apart and see if any one here might want some parts.. so i opened it up and instead of tearing it down i resoldered all the connectors including the SD/MMC.. then i removed the EQ wiring and jumped the connectors on the circuit board.. so the EQ wasnt hooked up.. lets face it.. you get a preset EQ along with BASS/TREBLE and then they add a analog EQ?? why?? this causes (at least on mine) serious distortion.. now with the EQ disabled.. (but still receiving power for the LED's) the Lasonic finally sounds halfway decent! i'm not sure if anyone else is have this distortion issue.. but if you are.. i will show you how to disable it with no chance of killin your brand new Lasonic!

first remove the back of the boombox.. then look for the EQ wiring coming from the front of the boombox..

the 4 wires that are under the blob of glue slightly to the middle right and left of the large grey resistor.. they need to be removed.. just those 4 wires.. the other 2 are for the EQ power LEDS.. after you remove them you jump the 2 spots where they were connected as shown in the picture..

then your all set! you will still have the lights on the EQ light up.. but they will no longer have any effect on sound.. which in my case was a godsend..

now the Lasonic sounds awesome!

Very interesting! Nice job getting it to sound better.

Which one did you get with preset EQ and analog EQ. Please show picture. Mine only has separate Bass and Treble with analog EQ and sounds great

you can access the preset EQ with the EQ button on your remote.. also here's something interesting.. where the old EQ preset switches are on the other models they are on this one too.. fully functional behind the sticker.. the new white BTQ has these opened and usable.. why they covered them in the all black model i have no idea.. but the circiut board is there and complete.. i took many inside pics of this boombox.. i'll post them for curiosity purposes soon.. oh.. and i'm sure this is obvious.. but you can switch parts from all models and make a freak Lasonic if you wanted to.. the new EQ board can be switched out with an ipod dock if you wanted to.. and all the speaker parts are interchangable.. just like the JVC Kabooms


and i find the best preset EQ to be the Loudness one.. the others sound like ass..

Actually the new white I931 BTQ looks like this and not other pics posted with chrome buttons.

Saw both of these listed on eBay. Seems there is the ALL WHITE with no buttons and the CHROME SPEAKER GRILL version WITH buttons

According to Lasonic there's only the all white with no buttons. The other is an old stock pic

hmmm. i seen the white BTQ with buttons also.. odd either way... since the preset EQ board is still there and fully functional behind the sticker.. why put it in there at all.. since it adds to the cost.. oh and another thing.. no point in trying to mod the LED EQ lights.. there intergrated into the sliders.. same with the LED in the LCD panel.. unless you switch with an older i931 board..

Ok guys I just got off phone with Lasonic. The only available White version of new BTQ is the all white. They said someone photoshopped the white/chrome version. Also the reason they kept the EQ preset in unit is because without it in there it had distortion. The presets are not set so the 5 band EQ and bass and treble are the only way to control unit...They also said anyone can purchase chrome parts to change the new units if wanted. So in conclusion the white version your seeing with chrome on eBay is not unit you will receive

Thanks for verifying that, Bill. You've saved me the hassle of a return.

And...

Thank you, Lasonic. I wanted to buy one of your new white boomboxes. But, you made it with no chrome. So, now I can buy something else with that money instead of one your products.

 

[mellymelsr]

Since the chrome pieces are available why wouldn't they offer both the black and white version with chrome as an option? Seems that would appeal to more buyers...

 

[Lasonic TRC-920]

This is a like a "Tuner Blaster" You buy the stock version and then after market parts to customize it

I honestly don't know what they are doing....

BUT, I may have to go down to Lasonic and MAKE THEM MAKE ME a new Vader Black with Chrome Rings!

I will have to look but if you keep off you should have no problems. Mine is off and sounds fine . The 5 band EQ is real cool for shaping different music.

The all white version without any chrome kind of looks like a half finished cheap toy.

Hi just about to do this with my limited knowledge in the department. I am confused as to how to "jump the wires." Will someone please explain...

 

[TMR]

jump the wires means to connect the 2 traces with wires or in my case excess solder.. make sure you know where to solder these.. the pictures show you exactly where to do it.. do it at your own risk! i will not be held responsible if you mess something up.. perhaps you should take it to someone who knows what they are doing.. if done correctly it does work perfectly..

 

[chrissayshi]

Awesome! It did just look like a blob of solder. I really appreciate you sharing this and responding so promptly.

Ok I have 5 Lasonic I931's.. 1- 1st edition IPod only closed door, 1- 2nd edition IPhone model open door, 1- 3rd edition no iPhone open door and Bluetooth, and 2- 4th editions with Bluetooth and EQ and I have no idea what distortion you are talking about but to me the EQ allows a much wider range of control with the set. If you use bass and treble controls it turns off the preset EQ and control is through Bass, Treble and graphic EQ. I just tested both my Darth Vader and White model with no distortion. For the price of about $140 it's still a great all around box and awesome loud outside box which I did test between Lasonic and Altec Lansing last summer I'm sure every once in a while there is a bad one sold just as with TDK, Altec Lansing and others have done
