Frequently Asked Questions - DEH-80PRS PIONEER

What DSP modes are available on the DEH-80PRS?

The unit offers two DSP modes: standard (STD) mode for a classic setup and 3-way network (NW) mode for active frequency separation (bass, midrange, treble).

How to change the DSP mode?

Use a small flat-head screwdriver to toggle the DSP switch on the back of the unit between STD and NW. After switching, press the RESET button with a pen to reset the microprocessor.

Can I use 3-way network mode with the internal amplifier?

Yes, in 3-way network mode with internal amplifier, signals are output as follows: white/left midrange, gray/right midrange, green/left treble, purple/right treble. Subwoofer outputs are dedicated to bass.

How to install the car stereo in a vehicle without ACC wire?

If the vehicle does not have an ACC position on the ignition, do not connect the red wire to a terminal that detects key usage to prevent battery drain. Instead, connect the red wire to a 12 V source controlled by the ignition.

What is the function of the blue/white cable?

The blue/white cable transmits control signals to turn on an external amplifier or motorized antenna (max. 300 mA, 12 V DC). Do not connect it to the power supply of an external amplifier to avoid malfunction.

How to connect an external power amplifier?

Use the front, rear, and subwoofer RCA outputs. Connect the blue/white wire to the amplifier's remote. In standard mode without internal amp, the speaker wires are not used.

Does the unit have a microphone input?

Yes, a microphone input is provided for voice recognition functions. The supplied microphone can be installed on the sun visor or steering column.

How to remove the front panel?

Press the front panel release button, push it upward, and pull it towards you. The panel is detachable to protect the unit from theft.

What types of files can I play via USB?

The car stereo plays audio files from USB devices and iPod. Supported formats include MP3, WMA, WAV, and AAC (see the manual for full list).

Is the unit compatible with steering wheel controls?

Yes, via a wired remote control input (not supplied), you can connect a steering wheel control adapter (sold separately) to control the car stereo from the steering wheel.

Installation Manual

- When installing this unit in a vehicle without an ACC (accessory) position on the ignition switch, failure to connect the red cable to the terminal that detects operation of the ignition key may result in battery drain.

ACC position

No ACC position

• Use of this unit in conditions other than the following could result in fire or malfunction.
  — Vehicles with a 12-volt battery and negative grounding.
  — Speakers with 50 W (output value) and 4Ω to 8Ω (impedance value).
• To prevent a short-circuit, overheating or malfunction, be sure to follow the directions below.
  — Disconnect the negative terminal of the battery before installation.
  — Secure the wiring with cable clamps or adhesive tape. Wrap adhesive tape around wiring that comes into contact with metal parts to protect the wiring.
  — Place all cables away from moving parts, such as the shift lever and seat rails.
  — Place all cables away from hot places, such as near the heater outlet.
  — Do not connect the yellow cable to the battery by passing it through the hole to the engine compartment.
  — Cover any disconnected cable connectors with insulating tape.
  — Do not shorten any cables.
  — Never cut the insulation of the power cable of this unit in order to share the power with other devices. The current capacity of the cable is limited.
  — Use a fuse of the rating prescribed.

— Never wire the negative speaker cable directly to ground.

— Never band together negative cables of multiple speakers.

• When this unit is on, control signals are sent through the blue/white cable. Connect this cable to the system remote control of an external power amp or the vehicle's auto-antenna relay control terminal (max. 300 mA 12 V DC). If the vehicle is equipped with a glass antenna, connect it to the antenna booster power supply terminal.
• Never connect the blue/white cable to the power terminal of an external power amp. Also, never connect it to the power terminal of the auto antenna. Doing so may result in battery drain or a malfunction.
• The black cable is ground. Ground cables for this unit and other equipment (especially, high-current products such as power amps) must be wired separately. If they are not, an accidental detachment may result in a fire or malfunction.

• After switching, reset the microprocessor.

Connections

WARNING

Do not use the unit in standard mode when a speaker system for 3-way network mode is connected to this unit. This may cause damage to the speakers.

1 Use a thin, flathead screwdriver to change the DSP switch on the bottom of this unit.

STD NW

2 Press RESET with a pen tip or other pointed instrument.

For details, refer to the operation manual.

Audio input

If you connect the unit to an audio device with RCA output, or to one with no RCA output, you can set it up so that the audio from the audio device is output through speakers connected to the unit. Change settings as necessary based on whether the connected device has RCA output or not.

For more details on change settings, refer to the operation manual or Switching between RCA input modes on this page.

Installing the microphone

CAUTION

It is extremely dangerous to allow the microphone lead to become wound around the steering column or shift lever. Be sure to install the unit in such a way that it will not obstruct driving.

Note

Install the microphone in a position and orientation that will enable it to pick up the voice of the person operating the system.

When installing the microphone on the sun visor

1 Install the microphone on the microphone clip.

① Microphone
② Microphone clip

2 Install the microphone clip on the sun visor.

With the sun visor up, install the microphone clip. (Lowering the sun visor reduces the voice recognition rate.)

④ Fit the microphone lead into the groove.

- Microphone can be installed without using microphone clip. In this case, detach the microphone base from the microphone clip. To detach the microphone base from the microphone clip, slide the microphone base.

2 Install the microphone clip on the steering column.
