DACODER 08 64X 12V
DACODER 0864X12V
Dengan xtal baru 9,728 Mhz
DACoder baru bisa mencapai
64X oversampling dgn normal
artinya berjalan real time
walaupun dicontrol
dengan micro
Dimensi aga mengecil dari
DACoder sebelumnya
menjadi 95mm x 70mm
DACoder 64X menjadi
xpert terakhir sebelum
meluncur ke DACoder 256X
yg dinantikan kelahirannya
selama ini oleh
broadcaster mania FM Stereo
semoga Allah meredhoi kita semua
Amien...
