Now I am a bit confused. I try to implement a 7.1.4. sound setup which will be used in UNITY or UNREAL. In my test I setup a voice event and added the RESONANCE AUDIO SOURCE as an FX to it (1). I set the position (2) and added the RESONANCE AUDIO LISTENER to a channel (3). Now what I don’t understand is why I have an additional surround mixer (4) and after that yet another surround mixer (5). What exactly do I control with 4+5 (see picture) ? ![image](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/0/0f727f2b71f1ab31312995669e4d5a1cadee84bf.png) ---

5 is the bus output panner. It’s part of the bus’ settings, and appears in the signal chain of every bus that outputs a signal with more than two speaker channels, just in case you want to manually adjust or automate the panning of that bus’ output. If you’re not planning to use it, you can safely ignore it; the FMOD Engine will optimize it away at run time. 4 is a panner effect that you have added to the bus’ signal chain. I’m not sure why you added it, but it allows you to pan the signal in the same manner as the bus output panner, but at whatever point in the signal chain you place it instead of only at the end. If you’re not using it, you should probably delete it. ---

can I use ONE global parameter to BYPASS the google spatializer (1) ? This way I could use the binaural headphones sound OR trigger on a second FMOD object spatializer effect for other output than headphone. ![image](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/0/05e7bd67afed2a80f8b00aa9164a7fa991e9f9a3.png) … ---

… so I could switch the A/B audio route: ![image](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/f/f9be82e8e7158c67df40aebf3030487d49528310.png) ---

> [@ScoringStageEU](#): > > can I use ONE global parameter to BYPASS the google spatializer (1) ? Yes. To do so: 1. Ensure the effect is not bypassed. 2. Select the “Enable Wet/Dry” command visible in the menu on your screenshot. This will cause the effect’s “Wet Mix” drawer to appear. 3. Automate the wet mix property on a global parameter such that its value is “All wet” when you do not want the effect to be bypassed and “All dry” when you do want the effect to be bypassed. If an effect’s wet mix is automated to “All dry,” the effect is automatically bypassed: It ceases to affect the signal and is optimized away to conserve resources until the met mix is automated back to a higher value. This method can be used to automate the bypass of any effect.
