PAC AP4-CH41 Manual

AP4-CH41

Introduction and Features

The AP4-CH41 provides a 6-channel pre-amp output for use with aftermarket audio equipment. Using the full range,
fixed level headunit output, in conjunction with CAN messages, the AP4-CH41 delivers a variable 5v RMS (max) pre-
amp output with fading, balance, equalization, and level control capabilities. The module also retains all audio from
other vehicle features such as factory Bluetooth, uConnect, and parking sensors. A data controlled remote turn on
wire is also provided by the AP4-CH41. When used in conjunction with the APA-TOS1 (sold separately), the module
can provide a variable 2-channel digital ((TOSLINK,S/PDIF) audio output.

Important Notes

1. The remote output is rated at 2A of current. If more current is needed an external relay must be used.
2. 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.
3. The chime volume and minimum volume levels are set to 0 dB by default. If you are happy with these levels it is not
necessary to make any adjustments. Please refer to the Setup and Configuration section on page 2 for more details.
4. The level control knob must be connected in order to manually adjust the chime volume and minimum volume settings.
5. The factory radio's speed controlled volume and surround sound mode are not supported by the AP4 outputs.
6. When using the TOSLINK output (APA-TOS1 sold separately), all chimes must be routed through the front output using DIP
switch 1.
7. No adjustments can be made manually using the programming button, or the factory SWC when the module is connected to
a PC.
