what is the meaning of PA amplifier?

what is the meaning of PA amplifier?

Amplifier not just for home audio, can be use for professional amplifications.

 

[wattaniya]

i mean (public address) or (professional amp)

 

[Tekko]

PA stands for Public Adress, but the manufacturers tend to call their products professional audio.

Audio products artists use to earn a living, thats where professional comes from, professional use.

 

[AndrewT]

PA = Public Address = good intelligibility if done properly. Does not mean good music reproduction, but can do good music if the design is compromised towards that target.

Disco speakers are a form of PA but the target performance is for music reproduction that particularly suits dancing. This does not equate to good music reproduction but can do if designed to that target.

Domestic sound system = music that suits the listener. Does not equate to good nor realistic. But it can be.

High Fidelity = the design target to reproduce music as life like as possible, so that it sounds realistic.

DIYaudio can fit any and all of these categories.

thank you for your answers.

hi apex. how can i use this for 2x24vac. can u please tell me the resistor needed to change and also their values?

regards.

1 Replace 1,5k/5w with 330R/2W for relay
2 Replace 0,1R/5W with 0,22R/5W for short-circuit detect
3 Replace 220k with 47k for DC detect
Rest will work with 35V DC, 6k8/1W for LED can be replaced with 3k9, but not necessary.

HELLO APEX SIR
CAN I USE 36.0.36VAC WITH THIS PSU? OR ANY CHANEGES IN PSU?

CAN U POST THE PSU TOP AND BOTTOM IN PDF FORMAT .

If you want to connect fan to F100 PSU use this circuit 'fan control' will turn fan on in case heatsink temperature is over 60deg. Fan out voltage on F100 PSU is over 15V DC with 12v ac input from transformer. Resistor 22R/5W can be change to get 3-4V voltage drop for different fans.

Do you have pcb design of H 200??

No, use pcb design from H100 as start point.
