Optimizing FireWire PerformanceAbout FireWire BandwidthFireWire bandwidth is shared between Apollo I/O streams, UAD plug-ins used within theDAW, and external FireWire hard drives. Available bandwidth also depends on the sessionsample rate; the higher the sample rate, the more bandwidth is consumed.FireWire bandwidth is displayed in the “FBW” meter in the UAD Meter & Control Panelapplication:Used by I/O streams (orange)Used by UAD plug-ins (blue)Available for hard drive streams (black)Available for UAD plug-ins (green)The FireWire Bandwidth meter in the UAD Meter & Control Panel applicationUAD Bandwidth AllocationThe UAD Bandwidth Allocation setting reserves FireWire bandwidth for UAD plug-insused within a DAW. It has no effect on UAD plug-ins used in Console, nor when connectedto the host computer via Thunderbolt. The default value (65%) a good starting pointfor most single-unit users; it should be adjusted according to your particular environment.Use the values in the table below as starting points when tuning the UAD BandwidthAllocation.Note: If using sample rates of 44.1 kHz or 48 kHz, we recommend increasing theUAD Bandwidth Allocation setting from the default of 65% to allow more UADplug-ins to run within the DAW when external FireWire hard drives are not used.Recommended UAD Bandwidth Allocation Values (single unit)Without external FireWire hard driveWith external FireWire hard driveSample Rate (kHz): 44.1, 48 88.2, 96 176.4, 192Mac: 80% 65% 55%Win: 75% 55% 45%Mac: 55% 40% 25%Win: 30% 25% 15%I/O buffer setting for best playback results 512 1024 2048Values apply for both Apollo and Apollo 16Note: See "Multi-Unit FireWire Bandwidth" on page 88 for recommended valueswhen multi-unit cascading.Apollo Software Manual19Chapter 2: Installation & Setup
