About FireWire Bandwidth<\/strong><\/h4>\n

FireWire bandwidth is shared between Apollo I\/O streams, UAD plug-ins used within the DAW, and external FireWire hard drives. Available bandwidth also depends on the session sample rate; the higher the sample rate, the more bandwidth is consumed. FireWire bandwidth is displayed in the \u201cFBW\u201d meter in the UAD Meter & Control Panel application:<\/p>\n

UAD Bandwidth Allocation<\/strong><\/p>\n

The UAD Bandwidth Allocation setting reserves FireWire bandwidth for UAD plug-ins used within a DAW. The default value (45%) allows Apollo to run at higher sample rates (88.2 \u2013 192 kHz).<\/p>\n

Important:<\/strong> If using sample rates of 44.1 kHz or 48 kHz, we recommend increasing the UAD Bandwidth Allocation setting to allow more UAD plug-ins to run within the DAW. See the table below for recommended values.<\/p>\n

To change the UAD Bandwidth Allocation setting:<\/strong><\/p>\n

    \n
      \n
    1. Quit all DAW software and the Console application (most UAD hosts must be quit to change this setting).<\/li>\n
    2. Open the UAD Meter & Control Panel application. It can be accessed under the blue UA diamond icon in the OS X Menu Bar at upper right of screen (as shown below).<\/li>\n<\/ol>\n<\/ol>\n

              UAD Bandwidth Allocation Notes:<\/strong><\/p>\n

                \n
              • To run more UAD plug-ins within a DAW, use USB, eSATA, or internal hard drives for audio session files instead of FireWire drives.<\/li>\n
              • Mac FireWire performance is better on some systems versus others due to the FireWire controller chips they contain. In general, newer Mac Pro, iMac, and Mac mini systems contain a superior FireWire controller chip and will deliver better FireWire performance than MacBook Pro systems. There is no simple method to determine which controller is used.<\/li>\n
              • Apollo has intelligent FireWire bus monitoring. If audio playback is compromised, a \u201cFireWire Interrupt Detected\u201d dialog appears. If that occurs, decrease<\/strong> the UAD Bandwidth Allocation setting for reliable playback. Note that even if the dialog appears during playback, audio file integrity is never compromised during recording.<\/li>\n
              • The UAD Bandwidth Allocation only applies when UAD plug-ins are used within a DAW. UAD plug-ins used within the Console application do not consume FireWire bandwidth.<\/li>\n<\/ul>\n","protected":false},"featured_media":0,"template":"","categories":[],"tags":[],"storecat":[],"itemids":[1320,1321],"manufacturers":[33829],"acf":[],"yoast_head":"\n\n\n\n\n\n\n\n\n\n\n\n\n\n\t\n
