DIY Mini Amplifed Speaker Kit Assembly Instrucons

1. Locate the two PCB’s and the enclosed component set for each.

 LocatethenysurfacemountamplierIC’sinthecomponentsetthataretobemountedtotheboomofthe

PCB’s.

 SoldertheICamplierstotheboomICpadsmakingsurethatthedotontheICisatpin1.

 (SeeFig.1)

2. RefertotheenclosedPCBcomponentlayoutdiagramfortheresistorvalueplacementandthecorrectorientaon

fortheelectrolyccapacitorsonthePCBandsoldertheminplace.

 Useanohmmetertomeasuretheresistorvaluesifnotsurewhichiswhich.

 Notethatthereisa50KpotenometerinRP1anda10KpotenometerinRP2posion.

 TheVUmeterLED’sD1,D2,D3aregreenD4isyellowandD5isred.

 (SeeFig.2)

3. Locatethetwolengthsofredandblackwires.

 SoldertheredtoV0+andtheblacktoV0-onP3ofbothPCB’s.

 Thesearespeakeroutputsthatwillbeconnectedtothespeakers.

 (SeeFig.2)

4. Locatethethreeconductorandfourconductorwirelengths.

 Selectthethreeconductorwire(red,yellow,black)andcutitinhalf(twoequalparts).

 Thiswillbeusedforthe5Vpowerconnecon.

 Stripbothendstoexposethewires.

 Cutotheyellowwiresonbothendsofbothwires.

 Solderaredwiretothe+5VandablackwiretotheGNDconnectorP1oneachoftheboards.

5. Selectthefourconductorwire(red,green,yellow,black)andcutitinhalf(twoequalparts).

 Thesewillbeusedfortheaudioinputandwillbeconnectedtothe3.5mmstereoconnector.

 Stripbothendstoexposethewires.

 Cutotheredwiresonbothendsofbothwires.

 Ononeofthecablescutotheyellowoneachendleavingblackandgreenwires.

 Ontheothercablecutothegreenoneachendleavingblackandyellowwires.

 ConnecttheyellowwiretoIN+andtheblackwiretoIN-onP2ofoneoftheboards

 ConnectthegreenwiretoIN+andtheblackwiretoIN-onP2oftheotherboard.

 (SeeFig3)

6. Peelotheprotecvepapercoangsontheacrylicspeakerenclosurepanels.

 Mountthespeakerstotheirfaceplatesusingthelargerdiameterscrewsandnuts.

 SoldertheredVO+andtheblackVO-wiresonthePCB’stothespeakerterminals.

7. Installfourbrassstandoswithnutstoeachofthetworearpanels.

 MountthePCB’stothestandoswiththelargerscrewswiththewiresfacingtheexitcutout.

8. Insert4oftheM2screwsintotheopeningsonthespeakerfaceplate.

 AachanM2nuttoteachofthescrews.

 Proceedtoinstalleachofthefoursidetopandboompanelstothespeakerpanellockinginthescrewsand

 nutsintothecut-outsonthepanels.

9. Takethetwored+5VandblackGND(P1)powerwiresfrombothPCB’sandtwistthetworedwiresandthetwo

 blackwirestogether.

 Solderthetwored+5Vwirestothecenterpinofthe2.1mmDCpowerconnectorprovidedandthetwoGND

 wirestotheoutsidegroundconnecon.

Fig.3

10. Takethetwoaudioinputwiresandtwisttheblackgroundleadstogether.

 Solderthegreenandyellowwirestothetwoinside3.5mmstereoconnectorpinsrespecvely.

 Soldertheblackwirestotheoutsidegroundconnecon.

 (SeeFig.4)

11. Connectthe3.5mmtoanaudiosource.

 ConnecttheUSBconnectortoacomputerportorUSBadapterandplugitintothe2.1mmDCpowerconnector

 justwiredtopowerup.

 Setthe50KRP1potenometertofullclockwiseposionformaximumvolume.

 Withpoweronandthespeakersplaying,adjustthe10KRP2potenometersothattheredtopmostLEDVU

 indicatorjustcomesonatmaximumvolume.

12. Runthepowerandaudioinputwiresthroughthecutoutontherearpanelandinstallthe

 rearpanelusingtheremainingM2screwsandnuts.

 (SeeFig.5)

13. Enjoythesound.
