Multi-System Setup (H9 & H10 Bands)

🏷️ System Identification

Each wireless system is labeled with a colored sticker for quick identification:

  • 🟢 H10 Band → Green round sticker
  • 🔴 H9 Band → Red round sticker

These stickers make the system easily identifiable in a multi-mic setup so that transmitters and receivers can be quickly matched.

⚙️ Before You Begin

  • Ensure all receivers and transmitters have fresh batteries or power
  • Keep all units powered OFF before starting
  • Place receivers in their final operating positions
  • Extend antennas fully

📡 Multi-System Setup Example

Scenario:

  • 2 × H9 systems (Red stickers)
  • 3 × H10 systems (Green stickers)

🟢 Step 1: Setup First Frequency Band (H10)

  1. Power ON only ONE H10 receiver
  2. Perform a Group Scan:
    • Press and hold the Group button until it begins scanning
    • The receiver will automatically select the best group

  3. Power ON the remaining H10 receivers (do NOT run group scan again)

  4. For each additional H10 receiver:
    • Set them to the same GROUP
    • Assign a different CHANNEL within that group
  5. Power ON all H10 transmitters:
    • Match each transmitter to its corresponding receiver (Group & Channel)

🔴 Step 2: Setup Second Frequency Band (H9)

⚠️ Keep ALL previously configured H10 systems powered ON during this step

  1. Power ON one H9 receiver
  2. Perform a Group Scan
    • This ensures compatibility with already active systems

  3. Power ON remaining H9 receivers (do NOT run group scan again)

  4. For each additional H9 receiver:
    • Set them to the same GROUP
    • Assign different CHANNELS within that group
  5. Power ON all H9 transmitters:
    • Match each transmitter to its receiver

🔁 Final Check

  • ✅ Each receiver has a unique channel within its group
  • ✅ Transmitters match their corresponding receivers
  • ✅ All systems are powered ON
  • ✅ No interference or audio dropouts

💡 Pro Tips

  • Always scan one system per frequency band only
  • Never run group scan on multiple receivers within the same band
  • Keep systems of different bands (H9 vs H10) grouped separately
  • Maintain line-of-sight between transmitters and receivers for best performance
