Windows installation instructions for SP-HUB-MIC-PRO and SP-HUB-MIC-ULTRA (Note: if you are using Windows XP, please call 609-267-4400)

NOTE: Do not remove the cover on USB port #4 - it is used by the internal soundcard and cannot be used for other USB devices. Only the 3 open USB ports are available for your USB devices.

To install the driver and setup your new hub-microphone, please complete the following:

1 - Download the latest Windows drivers here:

2 - Run the file and allow the drivers to install. Restart your computer once this has finished.

3 - Plug the USB hub-microphone into the USB port you intend to use and allow Windows to install the driver.

4 - Look on your Taskbar and find "Audio Commander" and open it.

5 - The Audio Commander is separated into segments. In the rectangular window of the playback section, click on the word "Andrea" (do not click the Andrea logo in the top left corner of the Audio Commander). The Windows "Sound" configuration window will open on the "Playback" tab.

6 - You should see several items listed on this screen. Look for the item with the word "Andrea" in the description. Double-click on the word "Andrea" and the "Speaker Properties" window will open. Click the "Levels" tab. You should see two level controls (if you only see one level control, the driver did not load correctly. See the troubleshooting section below). Turn both level controls up to maximum and unmute the microphone. Click OK. If the green checkmark is on the "Andrea" device, find your computer's internal soundcard listed on this screen and right click on it and select "Set as default device". The green checkmark will move to your computer's internal soundcard.

7 - Plug a pair of standard headphones into the green headphone jack on the microphone. Note: The pink jack on the microphone is for extension 'bench conference' mics, should you choose to use one. You should be able to hear your voice in the headphones. This is the 'live monitoring' feature. You can adjust the loudness by repeating step 6 above.

8 - Now click on the "Recording" tab. Double-click on the listing for the "Andrea" device, click the "levels" tab and turn the level control up to 100. Click OK. Click OK again to close this window.

9 - Back in the Audio Commander, in the recording section, look for a small box on the right side of the Audio Commander called "microphone enhancements". Deselect all boxes except "Noise cancellation" button. Leave this box checked. Now, set the Microphone Boost (at the bottom of the microphone enhancements window). For SP-HUB-MIC-ULTRA owners, change the microphone boost to +5dB. For SP-HUB-MIC-PRO owners, the default setting is +15dB. These settings should be a good place to start for most recording situations. You will ultimately select the amount of boost by looking at the recording levels in your software. All of the court reporting software programs have recording level meters to help you select the right amount of boost. Too much boost will result in scratchy, distorted sound. Too little boost will result in a recording that is too quiet.

10 - In the audio recorder section (at the bottom), click the record button and make a short test recording. Click stop. Click play. You should hear your recording coming through your computer speakers. If you do not hear anything, follow troubleshooting steps below. If you want to raise or lower the recording volume, use the 'microphone boost' in step 9. If you want to adjust the playback volume, do this with the volume control in the "playback" section near the top of the Audio Commander. You can now close the Audio Commander.

This completes the standard driver installation and microphone setup.

In your software, you will need to set the audio parameters. The terminology may vary somewhat, depending on the software you are using. These are the optimum audio settings for high equality audio:

Audio Input Device (or recording device): Andrea USB Audio Device
File Format: PCM (or WAVE)
Sample Rate: 22,050Hz (or 22.050kHz)
Bit rate: 16
Number of channels: 1 (mono)

Note: The most important part of getting a good recording with any microphone is to get the proper recording level. Most software has a recording level meter visible when you are recording. Make sure that the microphone boost noted in step 9 above is adjusted so that you see the recording level bouncing back and forth when people are talking. If the level meter hardly shows at all, you need to raise the mic boost. If the levels are so high that you see the red lines (in Case Catalyst) or its a solid line instead of bouncing (in Eclipse), then lower the mic boost. Ultimately, you want to record with the highest level you can without overloading.


Remember, if you wish to, you can plug an external microphone (for bench conferences) into the microphone jack of the USB microphone and the sound from the external mic will be blended together with the built in microphones. Please email us at for a list of compatible microphones for bench conferences.

Two very important things to remember about using any USB microphone or soundcard:

1 - Always plug in your USB microphone before opening your audio recording software. If you unplug the USB device at any time, you will need to restart the software for the USB device to be recognized.

2 - When you setup a USB microphone or soundcard, the settings are retained for that USB port only. If you move the device to a different port, you will need to set up the new port using these instructions. Any port that you want to use must be set up one time.


Troubleshooting section

If you are not getting a strong recording level, the microphone enhancements are not visible or the live monitoring is not working, then Windows did not install the driver correctly. Follow the steps below to reinstall the driver:

1 - Unplug the USB microphone

2 - If you did not already do this in step 1 above, download the latest version of the Andrea Driver here: . Please download this and save it to your desktop (do not run it right from the website). Once you have the file, double click the file on your desktop to run it. If it asks for permission to remove the driver, allow it to do so. After it completes the removal, run it again to install the new driver. If it installs during the first run, that is OK too.

3 - Restart your computer. When you are back to your desktop, continue below

4 - Plug in the USB microphone and allow Windows to install the driver again

5 - Open the Audio Commander. If you see the microphone enhancements, go back to step 7 above and complete the setup from there. If you do not see the microphone enhancements in the Audio commander, or your microphone recording volume level is very low, please use the following procedure to get Windows to manually recognize the correct driver.


1 - Unplug the USB microphone.

2 - Run the driver you downloaded to the desktop (in step #2 above) again. Allow the removal procedure to complete.

3 - Now run the program again to install the driver one more time.

4 - Plug in the microphone and allow the driver to install. Now we will take the necessary steps to force Windows to see the correct driver:

5 - In your Windows control panel, launch “Device Manager”

6 - Open the list under “Sound, video and game controllers”

7 - Right click on the “Andrea USB device” and select “Update Driver Software…” from the popup menu

8 - Click on “Browse my computer for driver software”

9 - Click on “Let me pick from a list of device drivers on my computer”

10 - Click on the “Andrea USB device”, then click “Next”

11 - When it finishes updating the drivers, click “Close”.

12 - Open the Audio Commander. You should now see the microphone enhancements and the microphone should now work correctly.
