The d:screet™ 4090 omni mic has an extremely linear fre-
quency response, fast transient response and is perfect
for calibration and system alignment applications. For high
SPL handling, the d:screet 4091 oers 144 dB SPL before
clipping, making it perfect for close-miking an electric guitar
amp, brass and drums. A foam windscreen and microphone
clip are included.
