The surround mix, in a browser.

You are on a multi-channel pass and the review is remote. The people who need to hear it are not sitting in a room with speakers behind them; they are on a laptop, wearing whatever they own, and you still need a verdict on dialogue clarity and on how the thing folds down.

Source-Nexus Review has a downmixer built into the plugin, so the fold-down happens on the bus rather than in a hardware box or a bounce. You choose a translation target, balance it, check it against the real mix, and send the result wherever the client already is — a browser room, or the conferencing app they were going to open anyway.

1. Insert Review on the surround bus. Open your spatial or surround session and insert the Source-Nexus Review plugin on the main surround master fader or surround monitoring bus, rather than on an individual stem.
2. Choose the downmix translation target. Right-click the Advanced Settings button in the plugin window and, under Process Mode, pick one: the Apple Spatial / Binaural Downmixer, for a client listening on headphones, or the Plain Downmixer, which folds the multichannel audio down to a standard stereo reference.
3. Set the pan law and confirm the channel configuration. Select your target Pan Law, which defaults to 3 dB constant gain, and check that the Channel Configuration in the plugin matches the source track it is inserted on.
4. Balance the fold-down. Click the Downmixer Advanced View button to open the individual channel faders and panning controls, and adjust the centre dialogue, LFE and surround channel gain for the stereo the client is actually going to hear.
5. A/B it against the real mix. Use the A/B Toggle button to switch back and forth between your raw surround mix and the downmixed stream, and listen for phase alignment and balance. Do this before anyone joins, not while they are waiting.
6. Either send it to a Gateway room. Map the To Nexus Chat path in Source-Nexus Review to your Nexus Broadcast driver, open Source-Nexus Gateway in your browser, select Nexus Broadcast as the microphone input, and share the room link with your client.
7. Or send it into Zoom, Meet or Teams. Route the plugin output to a virtual driver, then select that driver as the primary microphone or audio input device inside Zoom, Google Meet or Microsoft Teams.
8. Run the review. Play the timeline. Remote participants receive the binaural or stereo translation of your surround mix without installing extra drivers or owning a multichannel speaker setup, and their talkback comes back through the From Nexus Chat node into your headphones, isolated from your DAW master mix.

• The session layout is not the layout you want to fold down. Converting between surround channel layouts is a DAW job before it is a plugin one; support publishes How to Convert Between Surround Audio Channel Layouts in Pro Tools.
• You only need plain stereo into a call. Then this is a smaller job than the page above: How to Send Stereo Audio into Zoom using Source-Nexus I/O.
• You are talking over the mix and hearing yourself. The talkback switch and the mute and dim functions are what keep the control room out of the stream: Using the Talkback Switch and Using the Mute/Dim functions.
