Frequently Asked Questions - DEH-1700UB PIONEER
What audio file formats can the Pioneer DEH-1700UB play?
Via the CD player (CD-R/CD-RW), it plays MP3 and WMA files. Through the front USB input, it supports MP3, WMA, WAV, and FLAC (lossless audio). AAC and OGG formats are not supported.
What is the actual power output of the built-in amplifier?
The maximum power output is 50 W x 4 channels (MOSFET amplification). This value corresponds to peak power; the continuous nominal power (RMS) is significantly lower, typically around 14 W x 4 at 4 ohms.
How do I connect an Android smartphone to the car radio?
Connect your Android smartphone (version 4.0 or higher) via a USB cable to the front USB port. The car radio uses the MTP protocol to access audio files stored on the device. The phone's battery is also charged.
How do I use the RCA pre-out for a subwoofer?
The car radio has an RCA pre-out at the back, configurable in "rear" or "subwoofer" mode. Access the audio menu to switch between the two assignments based on your setup. A mono RCA cable is sufficient to connect a subwoofer amplifier.
How do I remove the detachable (anti-theft) faceplate?
Press the release button located to the left of the faceplate, then tilt the panel towards you and remove it. Store it in the provided protective case. Never leave the device without a faceplate exposed to the sun, as heat can damage internal components.
How do I set radio presets?
Tune to the desired station, then press and hold the corresponding numeric button (1 to 6) for about 2 seconds until the confirmation beep. The car radio allows up to 24 presets accessible via the FM and AM preset pages.
The car radio doesn't play my FLAC files from the USB drive - what should I check?
FLAC playback is available only via USB, not via CD. Ensure your files have the .flac extension and are not DRM-protected. If the issue persists, reformat the USB drive to FAT32 and copy your files again from your computer.
How do I adjust the equalizer and audio filters?
The DEH-1700UB includes a 5-band graphic equalizer and configurable high-pass / low-pass filters. Access the audio menu via the adjustment button to tweak each frequency band and activate the filters suitable for your speaker system.
Is the car radio Bluetooth or hands-free compatible?
No, the DEH-1700UB does not have built-in Bluetooth. For hands-free use or wireless audio streaming, you need to add an external Bluetooth adapter (hands-free kit or USB/AUX dongle) compatible with your vehicle.
Can an Apple iPod or iPhone be connected?
The car radio does not offer a Lightning connector or dedicated iPod interface. You can use the front AUX input (3.5 mm mini-jack) with any Apple device for audio playback, but control from the car radio will not be available.
How do I connect an external source via the AUX input?
Connect your audio player, phone, or tablet via a 3.5 mm mini-jack cable to the front AUX input. Then select the AUX source by pressing the SRC button until the corresponding indication appears.
What is the difference between the DEH-1700UBA, DEH-1700UBB, and DEH-1700UBG variants?
These suffixes denote regional variants of the same base model. The letters A, B, G correspond to versions distributed in different geographic markets (Europe, Australia, etc.). The main technical specifications remain identical between all variants.
