... Notes on Operation Do not fail to take the following precautions upon usage of the CXA1211M. 1. Countermeasure to cross talk between channels Fix a bypass capacitor to Pins CONT1 and CONT2 that control the amplifier gain. When the impedance of the control voltage source is visible, depending on the package volume and others, cross talk between channels is easily generated ...
