Portable Noise Generator

The Lectrosonics NS1 Portable Noise Generator is a

multifunction instrument designed primarily to facili-

tate fast, accurate setup of the Lectrosonics Modular

Automatic Mixing system. By providing a consistent

noise source, the input trim (gain) on each mic preamp

channel can be accurately adjusted to compensate for

the variation in sensitivity that occurs in some micro-

phone designs.

The built in speaker provides an acoustic noise source

for individual channel adjustment or to monitor exter-

nal signals connected to the ¼” jack. Wideband pink

noise or 3kHz 1/3 octave filtered pink noise is avail-

able at the balanced XLR line output for room

equalization and checking high frequency driver cov-

erage in multi-way speaker systems. The housing and

mechanical parts are made of machined aluminum for

lasting ruggedness in the field

Operating Instructions The NS1 provides a number of features to allow quick and easy setup of microphones and sound systems. NOISE BANDWIDTH The bandwidth of the noise can be selected from the front panel via the 3KHZ/PINK slide switch. Pink: In this position, the NS1 will output wideband pink noise for general purpose testing and level setting. 3 kHz: This position of the switch will output a pink noise signal which is bandpass filtered by a 1/3 octave filter centered around 3 kHz.
