Shure ILP-1 Condenser

The ILP-1 is a high-clipping level, low-noise preamplifier designed exclusively for use with Shure microphones.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 micro- phone 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. The supplied mounting clamps hold the preamplifier in place for permanent installations. Use either one or two
clamps depending on location and application
