Hello I have a problem with my woofer when functioning the sound disappear even when you increase the volume the sound disappear what might be the problem
I have a problem with the schematic u referred...the one on the site has 1 pot and yours has 2 pots how come can you please help me with the 2 pot connection
I think I explained in the video. If it's LPF, you disconnect 22k and inject bass signal to 1k resistor. If it Eq, you lift the two 22k , inject each with bass signal, Left and right from equalizer sub output
Please bro i need help translating the schematic. If you can show me or something like a very clear image of your pre amp ill appreciate. I texted you on WhatsApp.
I copied from that website of Tronics... There's part written 100k ohm fixed resistor, that one i replaced with 100k ohm potentiometer, that's where frequency is.
It's only three connections, power, i.e +12v, 0v,-12v. Then intercept sub signal after the two 22k resistors, take it to pre amp, then its output connect to 1k resistor taking to sub channel.
1st, balancing is the key, don't put everything to max, it will clip. 2nd, probably the subwoofer box isn't tuned properly. I'll make 2nd version of the preamp with more ICs. But that will need more powerful amp. This green board hardly reaches clean 80w
What is the maximum output of the bass speaker from the amplifier?
It can rarely pass 80w. There's a time I tried to measure, see it here

Hi Manu kindly help I have been given Sony Xplod 300 rms can green board be able to handle
Yeah, it will just observe not to surpass clipping level
@@emmanutechnician what if I bridge with one mid channel

What brand is the woofer?

On JRC 4558, pin 7, there is that R1 100k, that's the 2nd potentiometer B100k,
Thanks i was able to do the connection ..can u do a video abt the relay red board assembly
I have a preamp from shop, please instruct me on installation
My equalizer works properly when i connect my phone directly, but when i install Bluetooth device it doesn't work
There's a button to change between auxiliary and radio input on the EQ
After Getting the audio input from 1k resistor do you disconnect the two 22k resistor like what you did when connecting equalizer
I think I explained in the video. If it's LPF, you disconnect 22k and inject bass signal to 1k resistor.
If it Eq, you lift the two 22k , inject each with bass signal, Left and right from equalizer sub output
I ones assembled mine but the outcome was not a pure bass .it has some kind of destosions .What may have contributed to have such outcome??
Maybe you used the single power supply model, i.e 12v and ground.
The one have used is silent, provided you don't push gain knob to maximum
I used 12v 2.0 Amperes adapter to supply the pre amb
I aslo assembled one with 12v 2A and it distorted. Use the ones with dual power supply, like the one I've used. It's silent
Sir I was asking how to connect this lpf when you have an equalizer
It's easy, Bluetooth player to EQ, then sub output of Eq to LPF then to amplifier sub channel
Where are you located sir...my kisiagi is missbehaving
Am far off town
How much do u charge to fix the preamp
I just copied the circuit diagram I've shown
SO IF I HAVE AN EQUILIZER NO NEED OF THE PREAMP FOR MY RELAY REDBOARD
You can use both for better performance

True mid section ya green board ni best but bass ni bure kabisa
True, maybe you use it for mids, then gx series for bass
Gud work bro alfu unaeza tmia preamp na knob ya sauti juu ynye nkonayo Iko connected na knob side ya bass Kwa board
Bora inawork iko sawa. But hii yangu niliiprefer juu inaadjust gain na frequency
Kubuy mja kna hyo preamp ni how much
Can u use the pre amp and equalizer at the same time ?
Yeah, but they serve the same purpose
How much is the pre amp
This one was DIY, very few components
But do they in some way work as an equalizer
I have another simple bass preamp circuit for you to try. Let me know where I can send you the schematics
I was thinking of modifying this model with several 4558. WhatsApp me 0714874760
2.1 amp complete na usb player how much
How can someone reach you
I'll give contacts once I resume to Audio
Pale umetolea power ya preamp unaeza tolea equalizer pia
Yeah, but eq huwa naitafutia power adapter yake kando ya 12v 2amperes,
@@emmanutechnicianSeparation is the key
Good just explain more on connecting from juakali bass booster
It's only three connections, power, i.e +12v, 0v,-12v. Then intercept sub signal after the two 22k resistors, take it to pre amp, then its output connect to 1k resistor taking to sub channel.
mkuu fanya review ya gx
Ntaangalia. For now nilipata shughuli ingine sifanyi audio
Does the low pass filter and pre amp surve the same purpose
Yeah, they filter signals and send bass only to sub channel
Please can you assemble my amp
Hapo kuna place sikupati poa
Wapi
@emmanutechnician out put inashikashwa aje hapo kwa amp
Leta link ya schematics
I think I showed in the video, I'll check
I have one almost same as that but the bass is not that good, i mean doesn't sound better
1st, balancing is the key, don't put everything to max, it will clip.
2nd, probably the subwoofer box isn't tuned properly.

I've been waiting for the longest
