Tusanyuse okukulaba ku Roymall, wobudde bwo obw'ebintu ebirungi ebikwata ku ggwe. Tukwagala nnyo okukulaba era tukwagala okukwebaza okukola naffe. Tugenda okukwebaza okukola naffe nga tukwongera ku kiseera ky'okwagala mu bigulo byo. Bw'ogula naffe, tojja kufuna ebintu ebirungi ebitonotono ebitambuza obulamu bwo, naye ojja kufuna n'eky'okubonereza ky'omulembe ku buli kugula kwo. Otegefu okunoonya ebintu ebirungi ebitonotono ebigula? Noonya ebintu byaffe ebirungi, gula, era otungule okufuna eky'okubonereza ky'omulembe ne kugula kwo.Enkola Y'okutuma
Tujja kukola bulungi okutuma ebintu byo oluvannyuma lw'okugula era tujja kukakasa nti bijja kufika bulungi. Ebikwata ku kutuma bijja kufunibwa mu email yo ey'okukakasa.Mu ngeri yonna, ebintu bijja kutandikibwa okutumibwa mu nnaku 2.Mu kiseera ky'obuzibu, bijja kulemererwa nga bino: Bw'ogula ku Lw'okuna, Sabbiiti oba ennaku z'amawanga, bijja kulemererwa ennaku 2..Mu ngeri yonna, bijja kusasulwa mu nnaku 5-7 ez'okukola (Ku Lw'okubiri okutuuka ku Lw'okuna) nga tebirina kulemererwa ku nnyonyi oba ebirala ebitakozesebwa..Olw'okuba enkola yaffe y'okutuma eri mu nsi yonna, ekiseera ky'okutuma kijja kuteekwa okuba ku nsi gy'oli, kale kijja kutwala ekiseera era tusaba okumanya nti ojja kutunga nga oli mu nsi endala oba mu nsi endala.1.

Product introduction:
Using A1"s preamp and volume control original circuit, it has the inherent advantages of easy assembly, good impedance matching and smooth sound quality. In terms of sound performance, it can broaden the sound field, increase dynamics, and enhance resolution. You can also change different dual op amps to adjust the sound trend according to your own preferences.
Most dual op amps can be used directly and can be directly exchanged for AD827N, OPA2604AP, OPA2132PA.
This circuit is divided into two stages, the first stage is responsible for buffering, and the second stage is used as feedback volume control
(Each op amp is responsible for one channel). Its characteristic is that the input impedance does not occur when the volume is adjusted
Variety.
The music fax A1 front-end line is very simple and good sound. The good sound lies in the negative feedback adjustment, but the potentiometer of the original A1 line to adjust the volume is in the feedback loop and acts as a feedback amplifier resistor, adjusting the gain to adjust the volume, but there is a feature The volume can"t be turned off, but the volume is still adjusted to the minimum.
Note: The coupling capacitor uses 100V1UF/105.
Working voltage: dual AC AC12V~18V, dual 12V transformer is recommended
Finished board size: 70*40*25=length*width*height (unit MM)
Net weight: 40g (within 5g error)
Package includes:
1 x NE5532 Version Tone Board
