Tone Preamplifier - XH-M164 NE5532 Tone Preamplifier Board 4 Way Adjustment AC 15V

the folks at IC station have sent me another little module to check out this one is a tone control bass mid-range treble with an attenuator so we're gonna hook this one up and see how it sounds today I'm going to test the X hm1 64 this is an audio tone control board takes the line level input and gives line level output and it just requires a 12 volt AC transformer so 12 Center tap and 12 so dual 12 so here's our dual 12 transformer it's the same one I use for that tip echo board well connect our power to our three terminals here and we'll try those foam board out and see how well it performs so this is being an AC input polarity is not important as long as you've got your center tab ah the ground screw or the center tap screw then everything else will work that typically the reason why they required AC transformer instead of a a DC adaptor is because this device is going to generate it
