# Advanced Configs & Modulation Failover – Quick Guide

#### **What Is a Config?**

- A **Config** is like an advanced preset—nearly all transmitter settings can be saved.
- Configs can be triggered by:
  
    - Scheduler events
    - GPIO
    - SNMP commands
    - Modulation Failover (example shown below)

---

#### **Step-by-Step Setup**

#### **1. Create a Main Config**

Assuming you’ve already completed:

- Frequency
- RF Power
- Audio Input Setup

Now:

1. Go to **Automations \> Configs**.
2. Click **New**, give your config a **Name** and optional **Description**.
3. Select the sections to save (minimum: **Audio Processor** and **Exciter & Stereo**).  
   *Best practice: select **all sections**.*
4. Click **Save**.
5. Scroll down to review all saved parameters.
6. Click **Activate** on this main config.  
   ➤ It will now show as the active config at the top.

---

#### **2. Create a Backup Audio Config**

Let’s assume your backup is a USB audio source.

1. Go to **Audio Processor** and change input to **Audio Player In** (USB).
2. Save the change.
3. Go back to **Automations \> Configs**, click **New**.
4. Name and describe this config (e.g., “USB Backup”).
5. Again, select the relevant sections (same as before).
6. Click **Save**.

Now you have:

- **Main Config** (Analog Input)
- **Backup Config** (USB Input)

---

#### **3. Set Up Modulation Failover**

1. Go to **Automations \> Modulation Failover**.
2. Toggle **Enable** to **ON** (top right).
3. Under **Primary Source**, choose the **Main Config**.
   
     - You’ll see the current modulation input shown.
4. Click **Configure**:
   
     - Set **Audio Threshold**.
     - Set **Set Delay**: time before switching to backup (e.g., 5 seconds).
     - Set **Reset Delay**: time audio must be stable before switching back (e.g., 5 seconds).
5. Under **Backup Source 1**:
   
     - Toggle **Enable** to **ON**.
     - Select your **Backup Config** (e.g., USB).
     - Click **Configure**:
       
           - Set **Threshold** and **Delay**.
           - Enable **Revert to Primary** if you want it to switch back automatically when main audio returns.
6. Click **Save**.

---

#### **Live Test (Example Scenario)**

- If **main audio** is lost:
  
    - System detects silence.
    - Switches to **Backup Source 1 (USB)**.
- When **main audio returns**:
  
    - System detects it.
    - Reverts back to the **Primary Source**.

📝 All events are **logged automatically**.

---

#### **Additional Notes**

- You can set up to **3 backup sources**.
- Each backup source requires its own **Config**.
- Config files can be **exported/imported**—ideal for:
  
    - Backups
    - Transmitter cloning/setup
- For complex switching or automation, **contact Aqua Broadcast for training**.
