BUSES AND OUTPUTSSumma has 4 mains, 8 groups, 16 auxs and 32 tracks. Direct outputs and mix minus outputs can be assigned perpath from a pool of 188 mono resources.All outputs and buses are available for the currently accessed path via the routing tabs to the right of the control windowwith the touch display in ‘active Show’ view.Direct Outputs and Mix MinusDirect outputs and mix minus outputs are created on a per-path basis from the shared pool of 188 resources. Creatinga 5.1 direct output uses six of these shared resources, and for stereo direct output or mix minus output, two resourcesare used. For information on using mix minus outputs see “Mix Minus” on page 155 and for direct outputs see “DirectOutputs” on page 96.Configuring BusesTap BUSES & OUTPUTS in the Show menu to access bus configuration controls. The image below shows an exampleof each bus/output type. Each bus has a combination of the controls described here:• Width: The width drop-down menu allows you to change the width of each bus at any time to mono, stereo or 5.1.• User Label: You can enter a user label for each bus.• Level: Control the individual output level of each bus.• Access: acts in the same way as the physical access buttons above each fader on the surface. When a path isaccessed and the surface/touch display are in access mode, all control cells and parameters apply to that path.• AFL: Replace the current feed to the console monitors with the bus feed. AFL provides a non-destructive solo,allowing you to quickly check individual paths whilst maintaining all mixes-only the monitor output is affected, nopaths are cut and the mix to all other buses is preserved.• PFL: Route the pre-fade feed to the dedicated PFL speaker output. If PFL to MON is selected, the PFL feed willreplace the console monitor feed.• Output Listen: Like AFL, Output Listen provides a non-destructive solo, but in this case the feed is taken post-output delay, directly before the feed leaves the console.• Talkback: Route the feed from the talkback microphone directly to the bus or associated output• Tone: For groups, tapping TONE routes the tone source to the input of the group, similarly to routing tone to a channel.For mains, auxs and tracks, tapping TONE routes the tone directly to the bus output, prior to the point where it ispatched out of the system.• Downmix Type: Switch between using the LoRo or LtRt downmixing for 5.1 mains. LoRo maximises compatibilityat the expense of losing the front-rear separation that a Dolby Pro-Logic decoder could recover when using anLtRt downmix.• Cut: Cut the bus output.• Pre-Fader send cut if...: Cut the feed to the aux if the conditions selected in the drop-down menu are met.164 SUMMA Networked Audio Production System ROUTING
