VMX88L Audio Installation Processor

Finally, install gets the audio quality it deserves. Designed using the latest generation of NST DSP technology, VMX88L brings no-compromise audio performance and powerful system control to any audio installation.

VMX88L Overview

VMX88L delivers all the benefits and experience of our live sound filters and dynamics algorithms in an installation product. The 8 analogue inputs have individual compressors, as well as a 24dB/Oct high pass filter, 8 bands of parametric EQ and up to 1.3 seconds of delay. All of the 8 analogue outputs have 16 bands of parametric EQ, 48dB/Oct high and low pass filters, up to 1.3 seconds of delay as well as our high performance, two-stage PXL limiters for high performance loudspeaker protection.

All analogue audio connections are on Phoenix-type 3-pin 5.08mm pitch connectors. The 4 GPI connections allow configurable actions such as fire alarm mutes and preset recalls. Up to 100 presets can be stored with recall options allowing selective recall combinations of input, matrix and output sections.

Our D-Net control software for PC, Mac and iPad gives you complete control over ethernet and wifi. The VMX88L is also fully compatible with all our Venue Remotes for simple, flexible user control. Control via third party systems such as Crestron™ is available via our simple ethernet control protocol.
