Hi Guys

I have Presonus StudioLive III 32R Rack Mixer and I am trying to use the 16 analog outputs so that I can send any input signal to different devices connected to the 32R analog outputs to sample or record from but I cant figure out how to do this.

My Setup is as follows

StudioLive 32R Inputs
Input 1/2 - Montage M7
Input 3/4 - Fantom 7 EX
Input 5/6 - Kronos 3
Input 7/8 - MPC XL
etc. etc

I want any signal from any of the above inputs to go to the Analog Outputs to various devices for sampling & recording etc

StudioLive 32R Outputs
Analog Out 1/2 - 18i20 (Sampling to PC)
Analog Out 3/4 - UR44C (Sampling to MAC)
Analog Out 5/6 - MPC XL Sampling
Analog Out 7/8 - MPC Live III Sampling
Analog Out 9/10 - Zoom H6 Recording
etc. etc.

Any help would be very much appreciated

Thank you in advance

PreSonus StudioLive Series iii Flex Mixes || Aux Sends, Subgroups and Matrix

Spoiler: Gemini KI

To achieve this routing on your PreSonus StudioLive 32R, you will need to utilize FlexMixes configured as Aux Sends, paired with the mixer's Digital Patching (Soft Patching) matrix.

On the 32R, the physical TRS analog outputs (1–16) are hard-wired internally to FlexMixes 1–16. To send any input to any specific physical output, you must route that input through the corresponding FlexMix via UC Surface (the control software on your computer or tablet).

Here is exactly how to set this up step-by-step:

Step 1: Configure FlexMixes as Stereo Auxes
Because your sampling/recording targets are stereo pairs (e.g., 1/2, 3/4), you first need to link your FlexMixes into stereo pairs.

1. Open UC Surface and select your StudioLive 32R.
   
   
2. Go to your Mix Master section (the right side of the mixer screen).
   
   
3. Select FlexMix 1. Click the gear/settings icon to open its channel processing overview.
   
   
4. Set its type to Aux (instead of Subgroup or Matrix).
   
   
5. Click the Link button to pair FlexMix 1 and 2 together into a stereo link.
   • FlexMix 1/2 will now directly feed your physical Analog Outputs 1/2 (the 18i20).
6. Repeat this process for FlexMix 3/4, 5/6, 7/8, and 9/10, making sure they are all linked as stereo Auxes.

Step 2: Route the Inputs to the Correct Outputs (The Matrix)
Now that your outputs are ready to receive independent stereo mixes, you need to choose what audio gets sent to them.

1. In UC Surface, look at the Mix Select section (typically on the left or bottom, depending on your view).
   
   
2. Click on Aux 1/2 (which corresponds to your physical Analog Out 1/2). The entire mixer fader layout will shift to show you the "Sends" to Aux 1/2.
   
   
3. Bring up the faders for the instruments you want to send to your PC's 18i20 interface:
   • Want to sample the Montage? Raise faders 1 and 2.
     
     
   • Want to sample the Fantom? Raise faders 3 and 4.
4. Now, switch your Mix Select to Aux 3/4 (Analog Out 3/4 for your Mac's UR44C). Raise the faders for whatever instruments you want sent to the Mac.
   
   
5. Repeat this workflow for Aux 5/6 (MPC XL), Aux 7/8 (MPC Live III), and Aux 9/10 (Zoom H6).

Tip for Pure Sampling: To ensure the instruments go to your samplers completely untouched by the channel volume faders of your main room mix, change the Aux tap point. Select the Aux master, go to its settings, and ensure the mix position is set to Pre 1 (Pre-Fader / Pre-EQ) or Pre 2 (Pre-Fader / Post-EQ). This ensures that even if a fader is down in your main monitors, the signal still goes full strength to your sampler.

Step 3: Double-Check Digital Patching (If no sound is passing)
By default, FlexMixes 1–16 are mapped 1:1 to Analog Outputs 1–16. If someone has previously altered the routing, you can easily restore it:

1. Click the Gear icon in the top right corner of UC Surface to open Settings.
   
   
2. Go to the Digital Patching tab, then select Analog Outs.
   
   
3. Ensure that Analog Out 1 is assigned to FlexMix 1, Analog Out 2 to FlexMix 2, and so on down the line.

 

Thanks PulseWave but this is for the Console Mixer and not the Digital Rack Mixer, different products.

Yes — on the StudioLive 32R, the analog outputs are not a “copy any input to any output” patchbay by default. They are usually fed from the mixer’s mix buses, so the usual way to do this is to route each source to an Aux/Matrix mix, then assign that mix to the desired analog output pair. PreSonus also supports digital patching and external processor routing workflows on Series III rack mixers, which confirms that routing is done through the mixer’s internal patch/mix structure rather than directly from input to output jacks.fohonline+1

What you can do
For your setup, think of each output pair as a destination mix, not as a direct input tap. So if you want:

• Out 1/2 to feed the 18i20,
  
  
• Out 3/4 to feed the UR44C,
  
  
• Out 5/6 to feed the MPC XL,
  
  
• Out 7/8 to feed the MPC Live,
  
  
• Out 9/10 to feed the Zoom H6,
  

you would typically create separate Aux or Matrix mixes for each destination, then send the desired input channels to those mixes at the levels you want. Series III rack mixers support 16 FlexMixes that can operate as Aux, subgroup, or Matrix mixes, which is the mechanism used for this kind of routing.youtube

Practical routing method

1. Open UC Surface or the mixer’s routing page.
   
   
2. Set each pair of FlexMixes you want to use as an Aux, Subgroup, or Matrix, depending on whether you want a monitor-style send or a summed feed.youtube
   
   
3. Assign the mix bus to the physical analog output pair you want.
   
   
4. For each destination, raise the send levels of the input channels you want included in that output feed.
   
   
5. If you need the same source on multiple outputs, send that source to multiple mix buses at once.
   

For example, if you want Montage on Out 1/2 and Fantom on Out 3/4, you would send Input 1/2 to one bus and Input 3/4 to another bus, then map those buses to the corresponding analog outputs.

Important limitation
What you are asking for is possible as a routing concept, but not usually as a “one input directly mirrored to one output” per jack pair inside the analog output section. The mixer’s architecture is built around buses and patching, so each output pair generally carries a bus mix rather than a raw input channel. If you need a truly direct hardware-level split of every input to many outputs at once, an analog splitter or a dedicated digital router may be simpler.support.presonus+1

Best way to set it up
A good workflow for your use case is:

• Use one Aux or Matrix pair per destination device.
  
  
• Name each bus after the destination, such as “18i20,” “UR44C,” or “Zoom H6.”
  
  
• Patch that bus to the matching analog output pair.
  
  
• Decide whether each bus is pre-fader or post-fader depending on whether you want level changes on the main mix to affect the sampler feed.
  

If you want, I can lay out an exact bus-to-output routing plan for your 32R, including which FlexMix numbers to use for each of your devices.
