• Wide dynamic range and frequency response for accurate sound reproduction across the audio spectrum
• Interchangeable cartridges that provide an optimal polar pattern choice for each application
• Balanced, transformerless output for increased immunity to noise over long cable runs
• Supplied stand-mount adapter for portable applications (in-line preamplifier versions only)
• White or black finish that blends unobtrusively with most surroundings

The polar pattern of the cartridge is indicated by the model number suffix:

C = Cardioid, S = Supercardioid, O= Omnidirectional
