The KU5A also stands for the typically warm and pleasantly full, round ribbon sound known from AEA, which gives voices and instruments a particularly noble character and at the same time effectively softens sharpness in the treble range. Thanks to its active, transformer-coupled output electronics, the KU5A can be operated at any microphone input and does not require a special preamplifier with large gain reserves. A switchable high-pass filter with 6dB/octave at 283Hz is available to compensate for proximity effect. Like most active models, the microphone is powered via 48V phantom power.
