Network Technologies SM-nXm-AV-LCD operation manual Introduction, Specifications

Introduction

The SM-nXm-AV-LCD Audio/Video Matrix switch (VEEMUX-A) allows up to 32 audio/video sources (n) to be connected to up to 16 destinations (m). Different destinations can even be connected to the same source. Video resolution up to 1920x1200@85Hz is supported with no degradation – guaranteed. Stereo audio is supported, as well as volume control and separate audio/video switching. An LCD on the front panel indicates the current connections. The VEEMUX-A can be controlled by three methods: Front Panel Keypad, RS-232 interface, or optional Infrared Remote.
