Goldline MX4310 [RESTOCK ITEM]
4-Channel Microphone Multiplexer (with 3 Mics)

OUR PART #  MX4310-RST-01

Goldline's MX4 allows the user to enable single channels or any combination of channels, allowing for comparison of individual microphone locations versus the spatially averaged data from multiple microphone tests. Each of the four channels has a gain control to allow the user to match the input level from different locations.

The multiplexer can be used with all Gold Line 1/3 octave Real Time Analyzers and with most other popular models. The MX4 comes with three Model TEF04 instrument microphones.
