hi members
i need consultation ... do i need to include an OpAmp buffer before this equalizer module or i can directly line in it from my PCM2706 module? Now my setup is direct from PCM module to the equalizer module without the first stage OpAmp buffer.
My question is if i do not include the first Preamp stage and volume control will it causes noises to be introduced all the way into the amplifier? the module is ready made unit. As shown below. And i also noticed the module is notoriously noisy making noisy hiss if the gain is above +8dB ... is this a common problem with equalizer modules?
Opinions were well Appreciated. Thanks
