Pioneer DEH-S420BT is a 1-DIN car audio receiver for music and phone communication in the car.

FLAC playback suits an existing file collection, while the 13-band graphic equalizer provides more precise adjustment for the car’s audio system.
Pioneer DEH-S420BT is a 1-DIN Bluetooth car audio receiver designed for listening to music and handling phone calls in the car. It supports hands-free calling and wireless music streaming from a smartphone. Two Bluetooth phones can be connected at the same time.
Who this receiver is for
This model is suitable for replacing a car’s 1-DIN receiver. Its dual-phone connection is particularly convenient when several people use the same receiver or when the driver carries separate personal and work phones.
1-DIN describes the size of the installation opening, but it does not cover every aspect of installation. Electrical connectors, mounting arrangements and dashboard trim can vary between vehicles. Check both the dashboard opening and the vehicle’s connections before installation.
Connecting a phone
Pair the phones you use with the receiver through the Bluetooth settings. Once they have been paired, there is less need to keep switching the registered device whenever a different phone is used.
The model was designed for wireless connection with iPhone and Android phones. Current compatibility may depend on the particular phone and operating-system version.
Music files and connected services
The receiver plays FLAC files. This is useful if you already have a music collection in this format and do not want to convert the files before listening. The available information does not specify a particular source or storage medium for FLAC files.
This model was designed for use with Spotify Free, Spotify Premium and Pioneer Smart Sync. Support for these services may change over time. If one of these features is important to your purchase, check the current app and phone operating-system versions before choosing the receiver.
App integration and ordinary music streaming over Bluetooth are separate functions. Wireless music playback does not have to depend on a particular connected service.
Adjusting the sound
The 13-band graphic equalizer lets you adjust different frequency ranges individually. This gives you more control over the sound than basic bass and treble settings alone.
For an initial setup, leave every band in its neutral position. Play a recording you know well, then adjust one frequency range at a time. Small changes make it easier to judge the result without masking other parts of the music.
The lower bands affect the perception of bass, while the middle bands influence vocals and many instruments. The higher bands affect detail and brightness. Final adjustments are best made from your normal listening position inside the car.
The receiver includes Pioneer Advanced Sound Retriever audio-processing technology. This is a playback feature, not a separate file format or a method of connecting a phone.
Built-in amplifier power
The built-in MOSFET amplifier is rated at 50 W × 4. No measurement conditions are given for this figure, so it should not be treated as continuous or RMS power. When comparing this receiver with another model, use ratings measured under equivalent conditions.

FAQ
Does the 1-DIN format mean that this receiver will fit any car?
No. 1-DIN identifies the format of the installation opening. Vehicle connectors, mounting hardware and trim components may require a solution made for the specific car.
Can two phones be connected at the same time?
Yes. Two Bluetooth phones can be connected simultaneously. This is practical when sharing a car or using separate work and personal phones.
Will Spotify and Pioneer Smart Sync work with my current phone?
These features were designed for this model, but app support may change. Before buying, check whether the current Spotify and Pioneer Smart Sync versions are compatible with your phone’s operating system.
Is 50 W × 4 an RMS power rating?
No. The measurement conditions for this rating are not provided, so it should not be compared directly with continuous or RMS amplifier power.
How should I start adjusting the 13-band equalizer?
Begin with neutral settings and play a familiar music recording. Adjust one band at a time in small steps while listening from the driver’s seat.
