VM-8 Hardware Product Limited Warranty ...21



ETC’s VM-8 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-8 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-8 enables “mouse free” interaction with up to eight 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 twelve available Tx/Rx (Transmit/Receive) channels.

This guide will cover configuring the VM-8 in Windows XP Pro, Windows 7, and WAVE.

If the microphone is ‘permanent’, and will not be disconnected, you may choose to skip these steps.

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-8 has not been tested with it. The screen shots in this manual were taken with a VM-4. If you are installing a VM-8, your screens will reflect that.

Parts List

The VM-8 (Figure A) comes equipped with a USB “A/B” 2.0 cable (Figure B) and ETC Utility disc (Figure c)

Figure A Figure B 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-8 (Figure E). Upon properly connecting the VM-8 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-8 should not be disconnected until “New Hardware Installed” message is displayed.

Click on the SSoouunnddss aanndd AAuuddiioo DDeevviicceess icon (Figure 2). Check “PPllaaccee vvoolluummee iiccoonn iinn tthhee ttaasskkbbaarr”

box so you can access these settings quicker in the future if needed (Figure 3).

Figure 2 Figure 3

To ensure proper VM-8 Microphone performance, sound card settings must be adjusted after initial device installation (or sudden disconnect or power loss). Click on the AAddvvaanncceedd button in the

DeDevviiccee vvoolluummee box (Figure 4). The ETC VM-8 SSppeeaakkeerr mixer window will open. If your window does NOT show a MMiiccrroopphhoonnee device you will need to activate it. From the OOppttiioonnss drop down menu choose PPrrooppeerrttiieess (Figure 5)


Figure 4 Figure 5

In the PPrrooppeerrttiieess window check the MMiiccrroopphhoonnee box (Figure 6) then click the OOKK button (Figure 7).

Figure 6 Figure 7


You will see a MMiiccrroopphhoonnee device for ETC VM-8 in the SSppeeaakkeerr window. Using your cursor, move the SSppeeaakkeerr (master) volume lever up to the recommended playback level shown (Figure 8)

Figure 8

The MMiiccrroopphhoonnee volume lever must be down all the way and the Microphone Mute box must chcheecckkeedd ((FFiigguurree 99))

The microphone Mute box must be checked.

An unchecked Mute box will cause echo on the network and down-time for troubleshooting your installation.

The Recording volume for the VM-8 can now be adjusted. From the OOppttiioonnss drop down menu choose PPrrooppeerrttiieess (Figure 10).

Figure 10

In the PPrrooppeerrttiieess window click on the ReReccoorrddiinngg circle (Figure 11). Click the OOKK button (Figure 12).

The WaWavvee InIn (recording level) window will appear. Adjust the volume to the recommended level (Figure 13). Close out the WWaavvee IInn window (Figure 14), and any other windows left open, and your VM-8 is ready to be configured with WAVE Desktop Communicator software.

Figure 13 Figure 14

NOTE: The VM-8 utilizes standard Windows/Linux USB audio device drivers. If the unit is disconnected without using the ETC Utility, the settings may revert to default levels. These levels should be checked upon reconnection in the event the VM-8 becomes suddenly disconnected or loses power.

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 PrProodduuccttss folder (Figure 42). In the USUSBB PrProodduuccttss 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 YOYOUURR DEDESSKKTTOOPP zipped folder to your local computer’s desktop (Figure 43A).

Once you have copied (or moved) the CCOOPPYY TTOO YYOOUURR DDEESSKKTTOOPP folder, open it and click on the

The actual Batch file must be started now. Click on the SSTTAARRTT icon (Figure 48). The C:C:\\WWIINNDDOOWWSS\\ssyysstteemm3322\\ccmmdd..eexxee window will open and run through the process of activating the volume control service (Figure 48). When the process stops, close the window. To verify the


volume control service is running, check for the EETTCC icon in the system tray (the lower right corner of the screen by the clock) (Figure 49).

Figure 48 Figure 48A Figure 49

USB Microphone Removal Procedure (Option)

By right clicking on the EETTCC icon in the system tray (Figure 49), the UUnnpplluugg MMiiccrroopphhoonnee dialog box opens. Click on UUnnpplluugg MiMiccrroopphhoonnee (Figure 50). The Volume Control window will open. Click the OKOK button (Figure 51). A DDiissccoonnnneecctt CCoommpplleettee message will appear in the VVoolluummee CCoonnttrrooll window (Figure 52).

Figure 50 Figure 51 Figure 52

The Disconnect Complete window will self close as soon as the process is successfully stopped.

The ETC Volume Control service will automatically restart the next time a microphone is plugged in.

Uninstall ETC Volume Control (Option)


Go to the CC::\\WWIINNDDOOWWSS\\ssyysstteemm3322\\ccmmdd..eexxee directory run “stop.bat” (see Figure 48 pg 20). This stops and removes the service.

In the Windows Control Panel under “Add or Remove Programs” find ETC Volume Control and click the RReemmoovvee button.(Figure 53).
