Software Install Basics
Upgrading From an Earlier Version
If you are upgrading from an earlier version of SoundCheck 11.0 (or Beta version) you should copy
the old installation folder and name it "SoundCheck 11.0 OLD" before installing the new version. This
is a precautionary measure to keep you from overwriting sequence steps that you have customized.
Please see Upgrading From an Earlier Version on page 2 of the SoundCheck Manual.
Computer Setup
Please refer to Appendix: Hardware Compatibility List on page 345 of the SoundCheck Manual for
specific information on setting up hardware with SoundCheck on Windows operating systems.
Software Installation
Important! Make sure the SoundCheck USB hardware key is not connected to the computer. If it
is connected while SoundCheck is installed, the hardware key could be destroyed. The
software install reminds the user to remove the key before continuing with the
SoundCheck installation.
Important! Do not unplug the hardware key while SoundCheck is running. Doing so could destroy
the hardware key.
1. Place the SoundCheck installation disc in the DVD-ROM drive of your computer.
If your computer is setup to Auto Run, you will be prompted to install the software
Or, start the software installation by running Setup.exe in the root of the Listen DVD-Rom
2. Follow the instructions on the screen. Click Next to proceed.
3. During installation, you will be prompted for the
location of the status.dat file, which is unique to
the hardware key.
For example, the file status SC99999.dat is
automatically renamed to status.dat and then
copied to the SoundCheck 11.x\System folder.
The status.dat file is normally sent by email from
Listen, Inc.
Figure 1-1: Status.dat File
If the unique status.dat is lost, a new one can be sent by email.
Important! The file path for the Status file is part of the Edit - Folders setup. See
“Status.dat folder path” on page 10 of the SoundCheck Manual.

Hardware Key
In order to make real measurements the hardware key must be installed. Without the hardware key,
SoundCheck will run in demo mode. You can save, print and recall data. However, you cannot save
sequences or sequence settings. All data generated in demo mode is randomly adjusted in level and is
therefore not valid.
Hardware Key Installation
1. Insert the included hardware key into the USB port of the computer
AFTER SoundCheck is installed. The computer will recognize the
new hardware.
The hardware key should have a solid green light. (A flashing
hardware key indicates that the driver has not yet been installed.)
If the USB key is moved from one USB port to another, the driver will need to re-install for the
new USB port.
Important! Do not lose the hardware key for the SoundCheck system. It unlocks the functionality of
your SoundCheck software. For insurance purposes, this key represents the full value of
your system and should be noted in your company's list of assets. We recommend that it
be securely attached to the computer to avoid loss or theft.
Windows 7 & ASIO Devices
When using an audio interface with ASIO drivers, you must set the sample rate for the system in the audio
interface control panel. This over-rides the value set in the SoundCheck Hardware Editor. See “Appendix:
Hardware Compatibility List” on page 345 of the SoundCheck Manual.
CardDeluxe Installation
Install SoundCheck before installing the CardDeluxe sound card. The SoundCheck installation also
installs the CardDeluxe driver.
For more information on CardDeluxe settings refer to Appendix: CardDeluxe Installation on page 353 of
the SoundCheck Manual.
See Audio Device System Settings on page 349 of the SoundCheck Manual for information on
Windows settings.
If configuring a different sound card for use with SoundCheck See “Appendix: Hardware Compatibility
List” on page 345 of the SoundCheck Manual.
SoundCheck® 11 Quick Start Guide
Upgrading to SC 11
SoundCheck 11 features a fundamental change to the way hardware and calibration are handled. They are
now system-level setups rather than individual steps in a sequence. This means that you set them up once
in SoundCheck, and your hardware and calibration settings will be used for all sequences.
This tutorial explains the best way to upgrade from a previous version of SoundCheck.
Important! BEFORE you open or import any of your old sequences, please do the following.
Import Hardware
When you first open SoundCheck you will likely see the message box in
Figure 1-2 (unless you have a CardDeluxe and Windows XP).
Click the 'Open Editor' button to bring up the Hardware Editor.
Figure 1-2: Open Editor
Next, import a configuration for your particular sound card, either from
the default list in SC11 or from a Hardware Step in an older version of
Click the 'Import' button (Figure 1-3) to bring up the file dialog. You will see
a folder for Windows XP and a folder for Windows 7. Go into the
appropriate operating system and choose the setup that best fits your
sound card. If you would like to use an older hardware step, navigate to its
directory instead.
Figure 1-3: Click
Once you have chosen a .har file, you may get a prompt to Overwrite
channels as shown in Figure 1-4.
You will likely want to overwrite since the existing channels are for a
card you do not currently have.
Figure 1-4: Open Editor
Click the 'Open Table' button to review all of
your channels as shown in Figure 1-5. You
may delete any that are no longer needed
(right click - delete channel).
If everything looks good, click 'OK' then
'Save'. Note that you can import more than
one .har file and append more channels to
the list.
Figure 1-5: Hardware Table
SoundCheck® 11 Quick Start Guide
Import Calibration
Now that you have your hardware setup you will want to import the calibration configurations used by your
existing sequences. Now that calibration is system-level, you will need to have all the channels used by
your sequences in a single configuration.
When you first open the Calibration Editor, if you click on the
'Open Table' button you will see that there are a number of
signal channels already there for use with the example
sequences that come with SoundCheck. (Figure 1-6)
You may choose to keep or delete these with the exception
of Direct In and Out 1 and 2.
NEVER DELETE THESE CHANNELS, as they are used by
calibration sequences and must remain set to unity gain.
Figure 1-6: Calibration Table
From the main Calibration Editor (not table view) click 'Import'.
Figure 1-7: Import
Navigate to the .cal file used by your older sequences. If you used more
than one calibration step in the past you will simply need to repeat this
procedure. See Figure 1-8.
Just like hardware, if any of the signal channel names already exist,
you will be prompted whether or not they should be overwritten with the
imported version. See Figure 1-9.
Figure 1-8: Select File
Next, you will be asked whether or not to import the calibrated device
files (.DAT) associated with these signal channels. Click 'Yes'. If any of
those devices already exist you will again be asked whether or not to
Figure 1-9: Select File
SoundCheck® 11 Quick Start Guide
Once the channels are imported, they will each need to be assigned a
hardware channel. To facilitate this, SoundCheck will automatically open
the table and highlight in yellow the fields that need to be modified. See
Figure 1-10.
Assign the channels, then click 'OK' to close the table, then 'Save'. Your
calibration is now imported!
Figure 1-10: Modify
Highlighted Fields
At this point you can start bringing over the sequences from your older version of SoundCheck. If you have
not done so already, export the sequences from the old version. We recommend that you combine the
contents of all the exported folders into one, such that you only have one folder containing all your steps
and sequences. Then you can either open the sequences from this exported folder or easily import the
sequences into SoundCheck 11. Since you already brought in your hardware and calibration, the
sequences will open already connected to their appropriate channels.

Microphone Calibration Procedure
This procedure will allow you to check your measured microphone’s sensitivity against the microphone
manufacturer’s specifications.
1. Open the Calibration Editor and select the Input tab. The Calibration Sequence should be set to
2. Click Calibrate.
3. Select your calibrator model # from the drop down menu or select Other Calibrator and enter the
acoustic calibrator’s reference level and frequency.
The microphone calibrator's reference level should be indicated in its specifications as a given dB
SPL value (relative to 20µPa) at a reference frequency.
e.g., for the Brüel & Kjær Type 4231 Acoustic Calibrator:
Sound Pressure Level: 94.00 dB ± 0.20 dB
Frequency: 1000 Hz ± 0.1%
(When calibrating an artificial ear mic, you may need to select “B&K 4231 and UA1546”.)
4. Enter the gain or attenuation in dB that corresponds to the settings on your microphone power
supply or measuring amplifier in the Pre-Gain numeric field.
5. Select your measurement microphone model number from the drop down menu. If your
microphone is not listed in the drop down menu, choose Add New Mic.
6. Place your acoustic calibrator on your reference microphone and click Calibrate to measure its
The measured sensitivity of your reference microphone is displayed under Measured
Sensitivity in mV/Pa after clicking Calibrate. If the measured sensitivity is outside the
manufacturer’s specifications, a flashing FAILED message will appear. Check first to see if
your connections are correct or if the calibrator is turned on before assuming something is
wrong with the microphone.
The FAILED message can also appear if the Calibrator’s frequency is not correct. If a
Reference Frequency of 1000Hz is entered, but the Calibrator’s actual frequency is 1008Hz,
the Calibration may Fail. To verify the Calibrator’s frequency, use the Spectrum Analyzer
under the Operate menu.
The meter on the right side indicates the corresponding dB level relative to 1 Volt per Pascal. If
it varies by a few tenths of a dB from your last calibration measurement, do not be alarmed,
this is normal. If it varies by more than 1 dB or failed the sensitivity test, you may want to have
your microphone checked by a qualified calibration lab.
Add New Mic
This allows the user to enter a different microphone into the list. The sensitivity limits
can be entered for each new mic so that calibrations are made according to the
microphone’s specifications.
The check box for 1/2” Free Field Microphone should be checked only
when using this type of microphone
The calibration level is set to 93.85 dB SPL @ 1kHz when measured in a
pressure field, (such as a B&K 4231 Acoustical Calibrator).

Amplifier Calibration Procedure
A general wiring diagram and outline of the steps for amp calibration can be found in Appendix: Amp
Calibration - CardDeluxe Connections on page 373 of the SoundCheck Manual.
1. In SoundCheck, open the System Calibration Editor from the Setup drop down menu on the
SoundCheck Main Screen.
Important! Do not open the Amplifier Calibration sequence. Run the calibration from the System
Calibration Editor.
2. Select the Output Tab and select the Output Signal Channel to
calibrate. In the example in Figure 1-12 “Amp ch 1” is selected.
3. Select the proper Calibrated Device: “Crown Amp-L.dat“
If a new device is used with the system, click Add and enter a name.
Calibration values will be stored for this new device when the
calibration process is complete.
4. Select the Output Hardware Channel that provides signal to the
Amplifier Input: “Output 1“
5. Calibration Sequence should be set to “Amplifier Calibration“
6. The Input Signal Channel should be set to a Direct Input that is set
for Unity Gain. The sensitivity of this channel must be unity gain in
order to get an accurate calibration.
7. Turn the power amplifier off.
8. Connect SoundCheck Output 1 to the input of the Amplifier.
9. Connect the corresponding output of the amplifier to SoundCheck
Direct In 1. The amplifier output should not have an added Load.
10. Turn the power amplifier on. If it has a gain control, set it to
maximum. This is the most stable position for a gain control.
Figure 1-12: Amp
Some applications may require a lower gain amp. In that case, setting the volume control to a
lower level is acceptable, but less stable. If anyone bumps the control, the calibration will be
11. Click Calibrate to measure the amplifier’s sensitivity (gain) and frequency response.
The measured sensitivity of your amplifier is automatically entered in the output sensitivity field. If
the measured sensitivity fails, check your wiring and connections and try calibrating again.
If the measured response margin fails, check to see that the amplifier is not connected to anything
other than the sound card and that it is properly grounded. If there is a bump around 120 Hz (or
100 Hz if line frequency is 50 Hz), you might be picking up hum due to poor grounding or bad
