for Select Toyota Applications
AP4-TY13
The AP4-TY13 provides a 6-channel pre-amp output for use with aftermarket audio equipment. Using the full range,
xed level head unit output, in conjunction with data bus messages, the AP4-TY13 delivers a variable 5v RMS
pre-amp output with fading, balance, equalization, and level control capabilities. The module also retains audio from
other vehicle features such as factory navigation prompts, Bluetooth and Voice Activation. An accessory controlled
remote amplier turn on wire is also provided by the AP4-TY13. When used in conjunction with the APA-TOS1 (sold
separately), the module can provide a variable 2-channel ber optic digital audio output (TOSLINK).
Introduction and Features
Important Notes
1. Toyota Safety Connect (SOS) can easily be retained. See the Tech Brief "AP4-TY SOS Retention" at PAC-audio.com for
detailed instructions.
2. The factory radio's speed controlled volume, DSP, and surround sound mode are not supported by the AP4 outputs.
3. The factory amplier must remain connected, and in the vehicle after the AmpPRO has been installed.
4. Prior to testing, cycle the ignition off and back on again to properly initilize the AP4-TY13.
5. The radio's beep setting must be enabled on the factory radio in order to hear the audible tones when making selections
through the radio.
6. Initially, if the beep through the AP4-TY13 does not match the on / off selection through the radio, cycle the beep to the
opposite setting and back, then test again.
7. The radio's beep volume and minimum volume levels are set to 0 dB by default. If you are happy with this level in your
particular application, additional adjustment is not required. Please refer to the Setup and Conguration section on page 4
for more details.
8. The Radio's Nav / VR Voice, incoming E-mail tone, Ringtone, In-Call, Incoming SMS / MMS tone and Incoming SMS Voice
volumes can be adjusted through the radio's settings menu as they were prior to installation of the AP4-TY13.
9. The remote output is rated at 2A of current. If more current is needed, an external relay must be used.
10. 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.
