AKG Acoustics P220
Cardioid Condenser Microphone
The P220 appears to be a reissue of the popular Perception 220. Both are fixed Cardioid condensers with solid-state, transformer-coupled circuits, and switchable pad and filter.
The Perception 220 / P220 circuit is identical to that of the Neumann U87, albeit implemented primarily via surface-mount components.
The specifications for the P220 differ from the older Perception 220 in two respects:
- The sensitivity of the P220 is slightly higher, 20mV/Pa vs 18mV/Pa.
- The frequency response of the P220 shows a bump in the lower frequencies, whereas the Perception 220 begins its low-frequency rolloff at 80Hz.
According to AKG, the P220’s capsule and transformer are identical to those found in the Perception 220. Some components in the circuit have changed, and the factory has been able to improve tolerances.
In the sample microphone we inspected, two differences from the Perception 220 were evident:
- the high-impedance input circuit (two 1G resistors, JFET, input coupling cap) have been converted to surface-mount components.
- A second transistor elsewhere in the circuit has been converted to surface-mount.
