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 3rd party VoIP desktop application
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.

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.

The VM-4 (Figure A) comes equipped with a USB “A/B” 2.0 cable (Figure B) and ETC Utility disc
(Figure c)

Hardware Connections

Plug the “A” end of the USB 2.0 cable into an available USB 2.0 port on your computer (Figure D)
and the “B” end into the back of the VM-4 (Figure E). Upon properly connecting the VM-4 it will
install automatically with Windows/Linux drivers when you power on your computer. Please note
that it takes the system time to recognize new hardware has been hooked up, and that the VM-4
should not be disconnected until “New Hardware Installed” message is displayed.

Appendix

Microsoft .NET Framework (Option)

Note: The following steps are highly recommended if the microphone will be unplugged on a
regular basis.

When a USB audio device is disconnected the volume levels usually revert back to the factory
default settings. For maximum ETC equipment operation, these levels need to be set and stay
constant. The provided ETC Utility (installed later in this guide) uses Microsoft’s .NET Framework
4 to achieve this. Microsoft's .NET Framework 4 is free and can be downloaded at
http://www.microsoft.com/NET/

ETC Driver Utility Installation (Option)

By a quirk of Windows, sound devices were never meant to be portable / removable. Some of
these drivers date back to Windows-95 era. Since there are no provisions for portability, when a
device is disconnected the volume levels usually revert back to what is programmed in the
hardware of the soundcard. With the ETC series of USB microphones and sound cards this can be
inconvenient.

ETC’s Driver Utility makes sure the volume settings remain constant. This is a service running in
Windows, not actually a driver in the strict sense. As the volume changes these values are written
to the Registry. When a microphone is removed and later re-plugged, the previous volume levels
are read out of the registry and set in the Windows mixer panel.

Insert the provided Utility disc (Figure C, pg. 3) and open the UUSSBB PPrroodduuccttss folder (Figure 42). In
the UUSSBB PPrroodduuccttss folder, click on the IIMMPPOORRTTAANNTT–– RREEAADD MMEE FFIIRRSSTT icon (Figure 42A) and read
the enclosed text message (Figure 43). Make sure you copy the CCOOPPYY TTOO YYOOUURR DDEESSKKTTOOPP
zipped folder to your local computer’s desktop (Figure 43A).
