Shure ILP-1 Microphone Preamp for SM98

The ILP-1 is a high-clipping level, low-noise preamplifier designed exclusively for use with Shure Models SM90A, SM91A, SM98A, SM102B and SM102W, or for use as a replacement preamplifier for older Models SM90, SM91, and SM98. The ILP-1 connects to balanced microphone inputs providing 11 to 52 Vdc phantom power. Two switches on the ILP-1 allow you to set low-frequency response (flat or rolloff at 12 dB/octave) and gain (0 or +10 dB). The low cut switch minimizes ambient low-frequency noise from sources such as heating or air conditioner fans.
