Mal som problem so samovolnym resetovanim PODu. Nevedel som ci je chyba v napajacom konektore, konektore zdroja alebo niekde inde. Dal som to do zarucnej opravy a za mesiac sa mi to vratilo v jednakom stave ako to bolo. Nikto s tym nic nerobil a ostaval mi posledny mesiac zaruky. Nakoniec som zistil, ze pri manipulovani s napajacim konektorom od zdroja to sposobuje ten problem. Kupil som napajaci jack a skusil ci je problem v nom. Nebol. Nahodou som objavil taky isty napajaci konektor K375A v GM elektronike. Nadletoval som konektor na droty a zistil, ze problem bol v tom konektore. Vymena bola uz v celku jednoducha. Este som rozobral displejovu cast a ocistil displej od prachu a dal tam samolepiacu penovku. Snad to pomoze. Na zaver by som sa rad "podakoval" Made slovakia a ich slovenskemu servisu. Nic si od nich uz nekupim. :zdar:

tak to na slovensku funguje co si nespravis sam tak nemas ;D

Nevsimol si si, ake su tam prevodniky?

Dnes sa ti s takym starym crepom nebudu srat vari nikde na svete. Zahodme a kupme nove, konzumujme ;D

PODxt je 32 bitovy. Zakladom je 32 bit DSP procesor ADSP-21065L:  66 MHz, 198 MFLOPS, 3.3v, Floating Point. Snad nechces typ prevodnikov, to by som musel zasa otvorit a pozistovat co je co. :)

mna by tie prevodniky tiez celkom zaujimali, to uz mame taku uchylnu "tradiciu" s Matom :)

Takze na gitarovom vstupe je AKM AK4528VF, co je "HIGH PERFORMANCE 24BIT 96KHZ AUDIO CODEC" a tiez kvalitny operacny zosilnovac OPA2134UA "High Performance AUDIO OPERATIONAL AMPLIFIERS".

Potom je tam TLC1543C, co je "10-BIT ANALOG-TO-DIGITAL CONVERTERS WITH SERIAL CONTROL AND 11 ANALOG INPUTS". Ten bude na ovladanie digitalnych potenciometrov. Jedniny "analogovy" potenciometer je ten vystupny OUTPUT, ktory je aj stereo (dvojty potenciometer).

Je tam stereo USB audio interface TAS1020B. Pri nom je pamat Atmel AT88SC153: "1.5K EEPROM secure memory IC with Authentication; three 512-bit zones".

Nejake pamate sdram, logicke obvody a operacne zosilnovace tl082 a tl084.

Su tam tri obvody s nalepkami a viem, ze iba jeden je flash pamat. Bud je niektory z nich este AD prevodnik alebo ma ten DSP procesor uz analogovy vystup.

AK4528 ma aj M-Audio Audiophile 2496 alebo Echo Audio Mia

Takze to je celkom ok, nie? Len by to stacilo este preprogramovat, aby to hralo poriadne. Pridat nejaku konvoluciu a tak. ;D
