Top 5 Positive Customer Reviews for الصوت preamp و
Very good transaction with the Seller. Taken about 22 days to Switzerland. The item match the description. It was the transparent box with the potentiometer knob and screw. Very nice design. I asked the seller for the box. There is two options: transparent box or black box. I am happy with this. Thank's a lot!
Very good transaction with the Seller. Taken about 23 days to Switzerland. The item match the description. You need an AC power supply only. This board is very good made, the potentiometer and buttons are OK. With a scope, I made a measure of the two gains position: 5x and 10x. With a scope, I tell the frequency for the double of the voltage output. Bass: 100 Hz, Middle: 400 - 1500 Hz, Treble: 3500 Hz (this is an estimation and can be discussed). I am happy with this preamplifier. Thank's.
