I have the KA2284 audio spectrum analyzer module, I don’t know how to connect my 10 band equalizer to my 10 pcs KA2284 audio spectrum analyzer module. Can I ask for help or any suggestions?

[@hobbyelectroniccircuits7391]

You need a frequency divider circuit to divide low/mid/high frequencies (10 bands) and provide them into each KA2284 VU meter segments.

[@Le_Blnk____]

Can you just connect the mic input to the amplifier output?

[@hobbyelectroniccircuits7391]

In this circuit, I have connected the condenser mic into the spectrum analyzer circuit through a C945 based preamp circuit, or you can give audio signals directly to this circuit.

[@palashgosh9330]

I will benefit if Dada does 10 band circuit

[@hobbyelectroniccircuits7391]

You can modify this circuit into a 10 band spectrum analyzer by understanding the pattern used to divide frequencies between high, middle and low with more LM324 quad opamp ICs, 10 LB1403 ICs..

Meke peli 7 එකක් කරන්න පුළුවන් වෙයිද

[@hobbyelectroniccircuits7391]

පුළුවන්.
7-band spectrum analyzer කියල pcb දෙකක circuit එකක් ඉස්සර තිබුණා. LM324×2 & LB1403×7.
හැබැයි ඒකට +/-5V dual supply එකක් දෙන්න ඕන.

Kalau minta dibuatkan 20 band berapa harganya???bos

[@hobbyelectroniccircuits7391]

My circuit is designed for 5 bands.
You need 20 VU meter ICs (LB1403 or equivalent) and 5 LM324 quad opamp ICs.

මෙකට lb3915 5ක් දැම්මා වැඩ නැනේ

[@hobbyelectroniccircuits7391]

LB3915 ද LM3915 ද ?
ඒකට අදාල VU meter circuit එක හරියට හැදුවද ?

@@hobbyelectroniccircuits7391 lm3915 වලින් හැදුවේ, එවා 5 වැඩකරනවා, lm324 cricut එකට දුන්නම පත්තු වෙලම තියනවා line 4k, 222 දෙන එතරයි වැඩ කරන්නේ, lm324 ic එකේ out වලින් dc out වෙනවා, ic එක මරු කරලත් බැලුවා

[@hobbyelectroniccircuits7391]

මම LM3914/3915 වලින්නම් ඕක test කරල නෑ. LB1403/KA2284 series එකේ 5 outputs තියෙන IC වලටනම් වැඩකරනවා.
ඒවගේ vu meter එකකට LM324 circuit එකේ outputs එකඑක දීල බලන්න ඒ circuit එකෙන් හරියට frequency ටික divide වෙනවද කියල.

[@hobbyelectroniccircuits7391]

අනික ඕක single supply වලින් වැඩකරන frequency divider එකක් හින්දා DC තමයි out වෙන්නේ, outputs පහ vu meter එකට දෙනකොට 104 හරි 224 හරි 474 හරි capacitors series දාන්න.
