Pioneer MVH-190UBG Car Stereo

The Pioneer MVH-190UBG car stereo is a short-chassis 1-DIN digital media receiver designed for listening to music from USB and AUX sources or AM/FM radio in your car. It has no disc mechanism, making it suitable for systems built around digital audio sources.

Front-mounted connections and a clear single-line display make everyday operation straightforward. One switchable RCA pre-out can be configured to provide either a rear-speaker or subwoofer signal.

All technical details on this page are based on information supplied by the store because manufacturer documentation for this exact model was unavailable. Compatibility with current apps, services and Android phones should therefore be checked before purchase.

Installation and operation

The short 1-DIN chassis leaves more room behind the dashboard for plugs and wiring. This is particularly useful when the available installation space is tight.

The wide-viewing-angle VA LCD has one 13-character line and can display Cyrillic characters. Its brightness can be adjusted through ten levels, allowing the screen to be adapted for daytime or nighttime driving.

Display illumination effects and an illumination timer are included. The buttons are lit in green. The front USB and AUX connections are also illuminated, making them easier to locate in a dark cabin.

Music sources and connections

The front USB port is provided for connecting a music source. The front AUX input accepts another music device with an analogue audio output.

Compatibility with Android 4.1 or later was listed for playing music and audio from apps. This is the store’s original compatibility statement; operation with current Android versions, apps, services or phones has not been confirmed.

One RCA pre-out can be switched between rear-speaker and subwoofer use. There are no separate rear-channel and subwoofer outputs that can operate simultaneously. You must therefore decide which function is more important before connecting an external system.

Sound adjustment

The five-band graphic equaliser lets you adjust individual frequency ranges. Source level adjustment helps balance the volume when switching between radio, USB and AUX, reducing sudden level changes between sources.

A high-pass filter can limit low frequencies sent to the main speakers. A low-pass filter sets the frequency boundary for the subwoofer channel. The receiver also includes Direct Sub Drive.

Advanced Sound Retriever audio processing is included. The store lists a MOSFET maximum power rating of 50 W × 4; this is not a confirmed continuous power rating.

Radio functions

The RDS AM/FM tuner provides 24 station presets. Automatic tuning quickly locates broadcasts, while manual tuning allows precise frequency selection. The BSM function stores the stations with the strongest reception.

Alternative frequency search helps maintain the selected RDS station when its broadcast frequency changes. PTY search allows stations to be selected by programme type. The tuner also supports traffic announcements.

FAQ

Does this car stereo play CDs or DVDs?

No. It is a digital media receiver without a disc mechanism. You can listen through USB or AUX, or use the radio.

Which connection should I use for a phone?

USB was specified for Android 4.1 or later devices, but compatibility with modern phones, apps and services has not been confirmed. Choose AUX as an analogue alternative if your phone or adapter has an analogue audio output.

Can I use the rear and subwoofer RCA outputs at the same time?

No. There is one switchable RCA output. It must be configured for either the rear-speaker signal or the subwoofer signal.

How should I begin adjusting the sound settings?

Start by balancing the volume levels of the different sources. Then adjust the five-band equaliser. Set the filters according to the purpose of the connected speakers.
