📐 SYSTEM SETUP Instructions

STEP 1 — Hardware Power-Up

1. Charge everything before first use:
   
   

   • Wireless mic transmitters & receivers
     
     

   • Battery packs
     
     

   • PodTrak P4
     
     

   • Travel router
     
     

2. At the table:
   
   

   • Put the travel router near the mixer
     
     

   • Attach one battery pack to power:
     
     

     • The travel router (USB)
       
       

     • The PodTrak P4 (USB)
       
       

   • Mount the wireless receivers so the antennas are visible and not blocked
     
     

STEP 2 — Wireless Mic Setup

1. Turn on all wireless transmitters and receivers.
   
   

2. Pair each transmitter with its receiver (if not pre-paired).
   
   

3. Clip or wear each lav mic on your participants.
   
   

4. Connect each wireless receiver to the PodTrak P4 inputs:
   
   

   • Receiver audio OUT → PodTrak input
     
     

   • Use a 3.5 mm → XLR or 3.5 mm → ¼″ cable
     
     

Arrange inputs on the PodTrak so channels correspond to mic positions.

STEP 3 — Mixer (PodTrak P4) Setup

1. Turn on the PodTrak P4.
   
   

2. Set appropriate gain levels for each mic (start conservative).
   
   

3. On the P4:
   
   

   • Disable any heavy effects (to keep latency minimal).
     
     

   • Confirm clean mix sound on headphone output.
     
     

STEP 4 — Local Wi-Fi Network

1. Turn on the travel router.
   
   

2. Connect your iPhone to the router’s Wi-Fi network.
   
   

3. Have each listener also connect their iPhones to the same network.
   
   

You now have a local network visible to all listener phones.

STEP 5 — Connect iPhone to Mixer

1. Plug the USB-C to USB-C cable from the PodTrak P4 to your iPhone.
   
   

2. Open the custom iOS listening app (or a compatible pro streaming app if available).
   
   

3. Set the app’s input to the PodTrak’s USB audio source.
   
   

4. Confirm audio streaming begins (monitor on your phone first).
   
   

STEP 6 — Listeners Join the Stream

1. Each listener opens the listening app on their iPhone.
   
   

2. Connect to the stream (on the local router network).
   
   

3. Plug in their earbuds or use AirPods.
   
   

Every listener now hears the live table audio with low latency.

STEP 7 — Quick Sound Check

1. Talk into each mic and ensure levels are audible.
   
   

2. Confirm each listener can hear clearly.
   
   

3. Adjust individual levels on the PodTrak if necessary.
   
   

4. Confirm battery levels are good.
   
   

🔄 Daily Use Checklist (for next time)

• Batteries charged
  
  

• Router Wi-Fi up first
  
  

• PodTrak turned on second
  
  

• Mic receivers synced
  
  

• iPhone plugged in
  
  

• App open and connected
  
  

⚡ Latency Tips (To keep it minimal)

• Avoid Bluetooth earbuds during the critical testing period — wired earbuds first
  
  

• Once levels are right, test AirPods — Apple devices tend to handle Bluetooth well
  
  

• Keep the Wi-Fi router close to the group, not behind obstacles
  
  

🧠 Optional Upgrades Later

• Dedicated USB-C charging hub to charge iPhone while streaming
  
  

• Carry case with labeled cables
  
  

• Quick-launch script in custom listening app
