Getting Started
4.3 Macintosh OS9 Quick Audio Test
The installation of your AES16 can be tested using the Demo version of Bias Peak that was included on
your AES16 Installation CD. This is a quick way of verifying that the AES16 card is installed correctly and
is connected correctly to your external equipment.
1. Install the Bias Peak demo that is included on the AES16 installation CD, by clicking on the
peakTrial.sit file and following the installation instructions.
2. Locate “SineWaveMinus16.aif” on the AES16 Installation CD. Drag the file to the computer’s
desktop.
3. Connect the outputs of the AES16 to a digital destination (digital mixer, DA converters, etc.)
capable of delivering an audio signal for listening via headphones or speakers. Depending on your
external gear, you may be using the CBL-AES1603, CBL-AES1604 or CBL-AES1605 cables -
please check the Hardware Connections in this manual for details on correctly connecting these
cables to your equipment. Verify that DIGITAL OUT 1 of the AES16 is connected to your
external equipment. This is the output used for this test.
4. Before testing playback, the clock relationship between the AES16 card and your external device
must be established. For this test, the AES16 acts as the clock master while your external device is
a clock slave. Consult the manual for your connected equipment to determine how to set it to
receive sample clock from a digital input. Most digital devices offer several choices for sample
clock status, with “Internal” generally being the default. If your device does not have the ability to
receive its sample clock from a digital input, please consult Section 3.4 Common Studio Setups
for information on creating an alternate clock relationship with the AES16. Keep in mind that the
sample clock source of the AES16 is set to “Internal” primarily to confirm the validity of your
connections and installation – ultimately you should create clock relationships that make the most
sense for your specific situation.
5. Launch the Peak Demo application by clicking the Peak icon in the OS9 Applications Folder.
Peak will prompt you to open an audio file, choose “SineWaveMinus16.aif” on the desktop and
click “Open”.
• In Peak, click “Sound Out” from the Audio menu. Click “ASIO”.
