VMX88L Advanced Digital Audio Dynamic Processing Management System
The VMX88L offers the advantages and experience of our on-site sound filter and dynamic algorithms for fixed installation products. Each of the 8 analog input channels features an advanced compressor with an adjustable knee point, a 24dB/OCT high-pass filter, 8 selectable types of EQ, 2-stage dynamic equalization (DEQ), and adjustable delay of up to 1.3 seconds. The full matrix signal mixer allows analog inputs to be mixed to any output channel, providing flexibility in system design. All 8 analog outputs are equipped with 48dB/OCT high-pass and low-pass filters, 16 selectable types of EQ, adjustable delay of up to 1.3 seconds, and a state-of-the-art high-performance two-stage Predictive eXcursion Limiter (PXL) limiter design, aimed at providing optimal drive protection and minimal distortion. All analog audio interfaces use 3-pin 5.08mm pitch Phoenix connectors, with 4 GPI connections that allow customizable operational configurations (such as fire alarm mute and preset recall), and up to 30 presets can be stored and recalled, allowing for the selection of input, matrix, and output combinations. Our D-Net based Ethernet PC, Mac, and iPad control software not only allows you to control all devices on the network but also enables flexible storage of preset memories and system configurations (including in offline mode). The VMX88L is also fully compatible with our VR1 PoE remote control panel for simple and flexible user control, and can be controlled via simple Ethernet control protocols through third-party systems (such as Crestron, AMX, etc.).
