Power Amplifier using transistor w/ Bass Treble Control (stereo)

[Gbreaker]

Sir, patulong naman po, kasi nahihrapan na po akong mgresearch at hindi po ako makakita kung working sya.
Sana po makapagbigay kayo ng working diagram.


Nga po pla may na re-search ako pero ndi ko alam kung paano sya pagsasamahin as a whole circuit(Circuit  Connection.).:

Left & Right Channel: "Don't know how to connect each other"

Bass Treble Control: " saan ko po ito i-coconect sa amplifier?, may pre-amp na po ako."

Maraming salamat po.

Need help sir. . .

Hi,  this site might help you, pelase check    http://www.1diycentre.com/mcu_files/Page1039.htm

This is  a Digital Tone control, you might interested in..... there is a free dox which explain the :

1.  Tone Control
2.  Amplifier
3.  interconnections of Pre-amplifier, tone control, Equalizer, Amplifier

thanks sir, i will check it out. . . ^_^

Masters,

newbie pa lang..

Meron ako amp using tda2822m unfortunately nagkaroon problem yung isang speaker may output yung isa wala. later both nawalan ng output. ask lang kung paano ang tamang approach troubleshooting this problem. ayaw ko naman trial and error by buying a new ic tapos pick and place lang..

thanks po...

thanks po...

check mo po mga components gaya resistors, capacitors, wirings ng rca (line in line out), speaker, check mo din po PSU niya. kapag ok lahat ung IC sira

Question lang po: Ok lang po ba na walang "Pre-amp" ang isang Amplifier?
                      : Ano naman pokaya ang effect nito?


Newbie lang po Maraming salamat po sa inyo' ^_^

n general, the function of a preamplifier is to amplify a low-level signal to line-level. A list of common low-level signal sources would include a pickup, microphone, turntable or other transducer. Equalization and tone control may also be applied.
In a home audio system, the term 'preamplifier' may sometimes be used to describe equipment which merely switches between different line level sources and applies a volume control, so that no actual amplification may be involved. In an audio system, the second amplifier is typically a power amplifier (power amp). The preamplifier provides voltage gain (e.g. from 10 millivolts to 1 volt) but no significant current gain. The power amplifier provides the higher current necessary to drive loudspeakers.
Preamplifiers may be:
incorporated into the housing or chassis of the amplifier they feed
in a separate housing
mounted within or near the signal source, such as a turntable, microphone or musical instrument.

So possible po ba na walang Pre-amp ang isang Amplifier?? At possible po ba sa isang Power amplifier na i-amplify ang isang low-level signal?

pgkkalam ko kc ang pre amp acts as tone control.. gngmit un pr ma-adjust ang volume bass treble sk mid.. puede mo nlang lagyan ng volume control s input ng amp mo kung ayaw lgyan ng pre-amp.. pki correct nlang f mli mga master. sn mktulong

[landzkhie]

sir tanong ko lang po my konzert 302 amp ko kc ung right channel po kc mahina tumog-tog...? anu po ba ang cra nun?

sir gawa po kayo ng bagong thread ^_^

[landzkhie]

sir hengilbert ahm anu po ibig nio sabhin ahm anu pong bagong thread panu po b gumawa ng bagong thread...? Pa 2long naman po...! Tnxz po!

[taqui]

look nyo sa taas right side ung "new topic" subject nalang ung ampli at model.

[landzkhie]

sir taquinaga mahina po kc 2m0g-tog ung rigth chanel ng konzert 302... Pnu po b gmwa ng bagong thread?

depende sa sensitivity ng power amp mo, let's say your amp has a sensitivity of 2volts for full power output, then most likely using your cd palyer directly is possible, just make sure that your power amp has an input volume control...
