DR100W Amplifier, My new toy

[01110011]

ok lang tda8920

[zrehtiek/keitherz]

up ko lang ito. bakit yung inductor ko nagiinit?
what are the things to check?
may schematic po ba?

to n0th1n6;   

sir, can i order another kit from you?, tda8950 or higher wattage than tda8920? i'm using a bi-amp front speakers for my home theater and lacking amplifier for the subs. 1st, 2-channel using tda8920 drive L-speakers and 2nd 2-channel tda8920 drive the R-speakers all galing sayo. i used tda2005s for the surrounds.  i wish tda8950 to drive the subs.

if possible, pls. pm me the price.

thanks,
rud

May nakapag check na po ba kung ilan yung idle power consumption ng tda8920? At kung stable parin kahit long speaker wires ang gamit... thanks

^11watts....

[tony]

testing the latest version of the E-lab D-amp, a 150 watt per channel version...lower psu voltage was used this time....



this one will be housed in a "flaming red" chassis as requested.....

can't wait for the final project  appearance... more pix on its final casing.

Hello Sir, may nakuha ka na ba?

sa case mo sir, anong PSU ang gamit mo, secondary AC voltage?

OT:

sir Dandy may email at PM ako sa'yo...

Thanks sir! how bout yung mga typical 50w class AB? I'm considering idle power consumption kasi for my 5ch HT amplifier...

Oks, noted nakita ko na.

Mayroon ka na ba ibang amp at i-integrate mo lang?   O  planning to construct a 5.1 ch amp?   Mayroon mga IC integrated 5.1 ch amp na class AB,  D, T  in compact single pcb. 

In the DR100W, mayroon itong features na Shutdown mode which lessen the power consumption, it needs to be contorlled by MCU  or a simple logic switch.

Meron nako sir na 7.1 receiver, ang problem ko lang ay 5channels lang ang ginagamit ko so sayang yung idle power nung dalawa... at masyadong mainit yung receiver even on idle, so tingin ko malakas siya sa kuryente...

I tried to lower the bias setting, hindi na masyadong mainit pero medyo pumangit yung treble, i'm also after sound quality eh... Binalik ko nalang sa default bias setting...

Since may pre-outs yung receiver ko, plan ko gumawa ng external 5ch amp na maganda ang tunog(mas maganda sa receiver ko) and at the same time, low ang idle power consumption, kasi most of the time normal listening levels ko lang siya ginagamit...

Gumagana naman lahat ng function ng receiver ko kahit i-disconnect ko yung main power ng amplifier module niya... So I think makakatipid talaga ko sa kuryente pag hindi ko ginamit yung built in amp niya... Less heat na rin ang receiver kaya tingin ko mas tatagal na yung lifespan niya

@Dandy, meron pa ba tayong kits ng tda8950?

@Dandy, meron pa ba tayong kits ng tda8950?

@Sir Dandy is that okay to replace my tda8920 kit(first kit) to tda8950. My problematic PA admitted already sir noth1ng's Operating Room, I send last week of March.

@Sir noth1ng and @Sir Tony can I visit your lab this weekend or any day during weekdays you are available. I'll be in Manila tomorrow for a 15 days mechatronics training in UP-Diliman.

P.S.
Sir Tony I'll buy power supply for this toy (tranfo)
Sir noth1ng I"ll buy one SMPS

Thanks sir! how bout yung mga typical 50w class AB? I'm considering idle power consumption kasi for my 5ch HT amplifier...

efficiency of classAb is about 64~70% so a 50watt amp consumes about 72 watts at full blast...

you can call me 628-2996 when in Manila...

Thanks sir Tony. . . .
yeehey  first time to hear this non problematic PA from sir tony

[tony]

finished the drw150 in a flaming red chassis:

[j a y k e z]

wow ganda sir tony +1 hehehe

[tony]

thanks, me kasunod pa yan...
