6Ch Pre-Outs: The PAC AmpPRO AP4-FD31 provides a 6-channel pre-amp output for use with aftermarket amplifiers. Using the factory digital A2B audio data in conjunction with data-bus CAN messages, the AP4-FD31 delivers a variable 5V RMS pre-amp output with fading, balance, equalization, and level control capabilities.
Toslink Output: The AP4-FD31 can provide a variable 2-channel fiber optic digital audio output (toslink). Toslink fiber-optical cable sold separately.
Non-Fading Level Control Knob: Channels 5-6 (Sub) of the AP4-FD31 are non-fading outputs. The output level of channels 5-6 can be controlled using the supplied level control knob. The level control knob includes a 16' cable which plugs into the interface module and should be mounted in an accessible location at the front of the vehicle.
Data Controlled Remote Turn-On: A data controlled remote amplifier turn on wire is also provided by the PAC AmpPRO AP4-FD31. The remote turn-on is rated at 2A of current. If more current is needed an external relay must be used.
Retained Factory Audio Features: The PAC AmpPRO AP4-FD31 also retains all audio from other vehicle features such as factory Navigation Prompts, Bluetooth, Sync, and Warning Chimes.
Minimum & Chime Volume: If the minimum volume of your factory radio is too loud once the AP4-FD31 is installed, you can manually set the level of the minimum volume using either the programming button on the side of the interface or the factory SWC (Steering Wheel Controls) in conjunction with the supplied level control knob. You can also use AmpPRO PC app. You can also adjust the chime volume level.
AmpPRO PC App: Using the AmpPRO PC App (for Windows PC only) allows you to configure user interface options such as Minimum Volume Level, Chime Volume Level, and a 3-Band EQ from your Windows computer or laptop. The app can also be used to update product firmware.
- Minimum & Chime Volume Level: From the app you can set the minimum volume level of the factory radio, as well as the chime volume level.
- 3-Band EQ: Enables the 3-band EQ (Bass-Mid-Treble) with frequency and Q-factory adjustment. The Bass Frequency can be set to 60, 80, 100, or 120Hz; while the Bass Q-Factor can be set to 0.5, 1.0, 1.5, or 2.0. The Mid Frequency can be set to 500, 1k, 1.5k, or 2.5k; while the Mid Q-Factor can be set to 0.75, 1.0, 1.25, or 1.5. The Treble Frequency can be set to 7.5k, 10k, 12.5k, or 15k; while the Treble Q-Factory can be set to 0.75 or 1.25.
- Firmware: The AmpPRO app will also allow you to update the interface with new firmware as it becomes available.
Dip Switches:
- Switch 1: ON switches the interface into 2-channel mode. All outputs will be non-fading and all chimes are sent to channels 1 & 2 and the Toslink optical output.
- Switch 2: ON lowers the RCA output voltage to 4V. Set the dip switch 2 OFF to keep the RCA output voltage at 5V.
- Switch 3: Not used.
- Switch 4: This switch gets set to ON if installing the interface in a Mach-E series vehicle, and OFF for all other models.

Super easy install. Came with a bunch of extra wires for different applications, not sure why though, it was only for B&O systems and that would be the only set of wires to install with that system. Either way too much is better than not enough! Easy plug and play!
