[. . . ] The goal of setting a buffer size is to reduce it as much as possible without hearing any clicks, pops, or other glitches. If the buffer size is too small, the computer will not be able to make all the required audio calculations in time, and you will hear pops, clicks, and stuttering in your audio streams. On the other hand, if the buffer size is set too high, your computer will process audio without incident, but your software will feel sluggish and unresponsive. Sample Rate This drop-down menu sets the sample rate of Fast Track C400. Note that when using the interface with an ASIO or CoreAudio application, the sample rate can also be determined by your audio application. This parameter may not be editable from within the Fast Track C400 Control Panel if your audio application is running. In this case, any changes to the sample rate must be made through the audio application itself. If the application does not provide a way to set the sample rate, quit the application, then change the sample rate through the Fast Track C400 Control Panel. 22 Fast Track C400 User Guide To find your system's optimum buffer size setting, begin with a high setting and gradually reduce the size until you begin to hear clicks, pops, or other audible glitches in your audio. You may need to stop playing audio any time you change this setting and certain applications will require you to relaunch the program before the new buffer size settings become active. Pre-Fader Meters When this option is selected, the meters display the level of a signal before it passes the fader. This allows signal levels to be displayed regardless of the fader positions within the stereo mix (in other words, a fader can be all the way down and no sound will be heard from the mixer's output, but you can still see if there is any activity on that input). This menu only appears on Windows systems. Most Mac OS X applications allow to change the buffer size from within the audio application itself. Please see your audio application's user guide to learn how to change this setting. FX Sends Mode Pre-Fader FX Sends When Pre-Fader FX Sends is selected, the full audio signal will be sent to the FX Sends, regardless of the position of the Channel Faders of stereo mix 1­2. Driver Control Panel Options Hold Clipping Indicators until Clicked The top section of the meters (or right section for horizontal meters) of the Driver Control Panel feature a red clipping indicator. When this option is selected, the clipping indicators will remain lit until they are clicked. Post-Fader (Mix 1/2) FX Sends When Post-Fader (Mix 1/2) is selected, the audio signal level being sent to the FX Sends will be affected by the position of the Channel Faders of Stereo Mix 1. Load Clock Settings from Settings Files When this option is selected, the clock source and buffer settings are recalled when loading a settings file. This lets you load custom settings files with different low-latency mixer configurations without inadvertently changing the buffer size or clock source settings of the device. Post-Fader Meters When this option is selected, fader positions will affect the meters. Post-Fader Meters mean the meter indicate post-fader levels. Chapter 5: The Driver Control Panel 23 Flow Clicking the Flow button opens a display showing the signal flow from the inputs to the outputs of Fast Track C400. This is a useful reference for understanding the path of an audio signal flowing through Fast Track C400. Firmware and driver information Web links Viewing Firmware and Installer Information In this section, you can view the firmware version of the Fast Track C400 hardware, and the package version of the Fast Track C400 driver installer. About The About pop-up menu allows you to view the firmware version of the Fast Track C400 hardware, and provides convenient web links to product documentation, updates, support, FAQ, and registration. Accessing the Web Links Along the bottom-right of the Driver Control Panel you can easily access helpful online resources on our website (www. m-audio. com) by clicking on the following pop-up menus: · Manual · Updates · Support · FAQ · Register Your computer must be connected to the Internet in order for these links to work. 24 Fast Track C400 User Guide Monitor Mixes The monitor mixer allows you to create two different stereo mixes from 10 input sources consisting of any of the hardware inputs (2 analog and 2 digital inputs) and software returns (6 software returns). This allows you to set up nearzero latency cue mixes in which the performers hear a "customized" mix while recording. It is important to note that any changes made to the monitor mix will only affect what is audible from the mixer's outputs--the monitor mix does not affect the signals that are sent to your software for recording. For example, if you are recording a vocalist and they tell you to turn up the vocal track so they can hear themselves better, you can increase the vocalist's microphone channel in the monitor mix. This will make the vocal part louder in the vocalist's headphones, but it will still be recorded into your software at the volume determined by the top panel Gain Knob. The monitor mixer is set up like a standard mixing console: There are 4 input channels, each with its own volume fader, pan and aux send knobs, solo, and mute buttons, as well as a master output section with its own fader. A pair of channels can be linked together by clicking the link icon between the two channels. Linking channels allows you to adjust mute, solo, and fader settings simultaneously by modifying parameters on either one of the linked channels.
