PAC AP4-FD11 Manual

AP4-FD11
Introduction and Features
The AP4-FD11 provides a 6-channel pre-amp output for use with aftermarket audio equipment. Using the full range,
fixed level head unit output, in conjunction with CAN messages, the AP4-FD11 delivers a variable 5v RMS pre-amp
output with fading, balance, equalization, and level control capabilities. The module also retains all audio from other
vehicle features such as factory navigation prompts, Bluetooth, SYNC, and parking sensor chimes. A data controlled
remote amplifier turn on wire is also provided by the AP4-FD11. When used in conjunction with the APA-TOS1 (sold
separately), the module can provide a variable 2-channel fiber optic digital audio output (TOSLINK).
Important Notes
1. This interface is only compatible in vehicles equipped with a data bus controlled premium sound system. To verify
compatibility, look for a Sony or THX badge on the door speakers, center speaker, or factory sub woofer. If none of these
brands are shown, check for the presence of a center speaker or sub woofer.
2. The factory amplifier must remain connected, and in the vehicle, after the AmpPRO has been installed.
3. The remote output is rated at 2A of current. If more current is needed an external relay must be used.
4. Channels 5 and 6 are non-fading outputs. The output level of channels 5 and 6 can be controlled using the supplied level
control knob.
5. The chime volume and minimum volume levels are set to 0 dB by default. If you are happy with this level in your particular
application then additional adjustment is not required. Please refer to the Setup and Configuration section on page 2 for
more details.
6. You can only use the factory seek / track buttons to activate the chime and minimum volume adjustment in vehicles
equipped with the factory center stack radio.
7. The chime volume only controls the level of the radio button beep. This can be turned off in the radio settings menu.
8. The level control knob must be connected in order to manually adjust the chime volume and minimum volume settings.
9. The factory radio's speed controlled volume and surround sound mode are not supported by the AP4 outputs.
10. No adjustments can be made manually using the programming button, or the factory SWC when the module is connected to
a PC.
