Introduction
ETC's VM-4 programmable microphone is designed to integrate with desktop VoIP (Voice Over
Internet Protocol) applications – in this case Twisted Pair's WAVE Desktop Communicator. The
VM-4 is ideal for situations where a multi-channel, plug-n-play, desktop audio interface is needed.
With virtually any USB (Universal Serial Bus) compliant PC and 3
software, the VM-4 enables "mouse free" interaction with up to four channels of audio without the
need to 'point-and-click' on the Desktop Communicator itself.. This allows the user to speak on the
'hoots' while performing other tasks on the PC. An RJ45 (Registered Jack) port is provided for
connecting up to four external PTT (Press To Talk) switches giving the user eight available Tx/Rx
(Transmit/Receive) channels.
This guide will cover configuring the VM-4 in Windows XP Pro, Windows 7, and WAVE.

NOTE: The application software versions used in this guide are Windows XP Pro, Windows 7,
Microsoft .NET Framework 4, and WAVE 4.8 (which requires Internet Explorer 7 or higher). If you
are using any other versions of these products your windows may look different. Linux is noted in
this manual, although the VM-4 has not been tested with it.
