The CAD Audio E300S Multi-Pattern Condenser Microphone is a revised version of the coveted E300. The E300S is designed to provide the same sonic character as the older E300V2. Switchable cardioid, omnidirectional and figure 8 polar patterns are provided on the front. Also features a -20dB pad and high pass filter switches. The E300S is powered with a pair of 9V NiMH batteries and phantom power is used to recharge the batteries while in use.
