Note 1: The resistor In series with the output of each channel sets the volume of that chol If you have a higher wottoge stereo, use o smaller resistance and If you have smalle gain of your stereo and not the wattage, so the resistance volue given by the watt choose not to use o resistor you should be advised to turn the volume on your ste Note 2: The ouputs from this sound board ore designed to be roughly compatible with the lin into the microphone jacks without the proper impedance matching transformer installe Note 31 The KS55 is Samsung's part number for a low power 555 timer. If you can not find ( Note 41 The MC1408 con be used as o direct replacement for the DAC0808. I have o prefere and CMOS logic. If you can't get 74HCT feel free to substitute 74LS or 74 series p
