CardioidAKG Acoustics Perception 150

Cardioid Pencil Condenser Microphone

The Perception 150 is an inexpensive small-diaphragm FET condenser microphone with a fixed cardioid pattern and transformerless output. It has been replaced in the Perception product family by the Perception 170, which appears to be identical in every feature and spec aside from the pad (and therefore the max SPL).

Although AKG states the mic’s frequency range as 20Hz - 20kHz, the frequency plot stops at 50Hz on the low end. It dips -2dB at 20Hz and 5kHz, with a presence peak (+6dB) at 10kHz, sloping back to -2dB at 20kHz. This plot is identical to that of the Perception 170.

Perception 150/Perception 170 Capsule Head ComparisonNote the differences in capsule vent size and shape of the Perception 150 (left) and Perception 170 (right). Although subtle, these differences could have an effect on the high-frequency response of the two microphones, despite the identical response graphs.

A switch on the body of the Perception 150 enables the -10dB pad. (On the Perception 170, the pad gives 20dB rather than 10dB of attenuation.)

It ships with a storage pouch and a mic clip.

The Perception 150, like the rest of the Perception series, is manufactured in China to AKG’s specs and standards.
