Display Features

Detachable Face Security: This unit features Detachable Face Security. A face-fixing screw is supplied for making the face non-detachable, if desired.

Multiple-Color Illumination: This unit is equipped with multiple-color illumination for its front-panel display and backlit buttons. You can select from 30 preset colors (White to Rose), cycle through all preset colors (Scan), or customize an illumination color (by adjusting Red, Blue, and Green brightness levels). The head unit's display illumination and button illumination are always the same color.

Ever Scroll: When the Ever Scroll feature is set to On, recorded text information scrolls continuously on the display. It will auto-scroll up to 64 characters. Set this feature to Off if you prefer the information to scroll only once.

Display Illumination/Clock Display: When the Clock Display has been turned on, pressing and holding the Source button turns off audio output, but the clock display remains on. When the Clock Display has been turned off, pressing and holding the source button turns the unit off completely. Even if you have turned the radio completely off you can view the clock display by pressing the clock button. The clock will then remain On until you turn it back Off. When the unit is On you can select between the clock display or the audio track/tuner display.

24 Bit D/A Converter: The Pioneer in-dash head unit utilizes a 24-bit digital to analog converter for superior CD sound quality.

MOSFET Amplifier: The DEH-4300UB is equipped with a MOSFET amplifier. Compared to conventional power supplies, the MOSFET amplification circuit is smaller and more efficient, and it delivers increased power with less distortion and absolutely zero on/off switching noise. More power means louder and cleaner music at higher volumes because you're not pushing the limits of the amplification circuit.

CEA2006 Compliant: The power specifications for the DEH-4300UB are compliant with the CEA2006 Mobile Amplifier Power Testing and Measurement standards from the Consumer Electronics Association (CEA). These standards were developed as a way to equitably compare power specs from model to model and between manufacturers. The power output specs for the DEH-4300UB are as follows:

• CEA2006 Specs: 14 watts RMS x 4 channels (at 4 ohms, 20Hz-20kHz, 1% THD-N)
• Continuous Power Output: 22 watts RMS x 4 channels (at 4 ohms, 50Hz-15kHz, 5% THD)
• Maximum Power Output: 50 watts x 4 channels (or 50 watts x 2 channels at 4 ohms + 70 watts x 1 channel at 2 ohms for subwoofer)

3-Way Rotary Commander: The Pioneer DEH-4300UB features a 3-Way Rotary Commander for easy control. You can scroll through your music and audio settings with greater ease using the 3-way rotary commander.

Advanced Sound Retriever: The Advanced Sound Retriever automatically enhances compressed audio and restores the original richness of the recording. When Advanced Sound Retriever is on, the high frequency range is compensated to match the frequency response curve to the original sound. There are two available levels of the Advanced Sound Retriever effect.

EEQ (Easy EQ): The DEH-4300UB is equipped with a 3-band EQ with 6 preset EQ settings: Powerful, Dynamic, Vocal, Natural, Custom, and EQ Flat. The Custom band can be adjusted as follows:

• Bass: +/- 6dB at 100 Hz
• Mid: +/- 6dB at 1 kHz
• Treble: +/- 6dB at 10 kHz

Loudness: The Loudness feature compensates for deficiencies in the low and high sound ranges at low volume. You can set the Loudness feature to Low, Mid, High, or Off.

Source Level Adjustment (SLA): This function lets you adjust the volume level of each source to prevent radical changes in volume when switching between sources. Settings are based on the volume level of the FM tuner, which remains unchanged. Each source can be independently adjusted from -4dB to +4dB.

Dual 2.0-Volt Preamp Outputs: The Pioneer DEH-4300UB features two pair of 2.0-volt preamp outputs (Front & Rear/SW). The unit's rear preamp output can be configured as a fading rear-channel output or a non-fading subwoofer output with a low-pass filter, phase adjustment, and output level control. When configured as the subwoofer output, you can select the frequency of the 18dB/octave low pass filter (50, 63, 80, 100, or 125 Hz), select the subwoofer phase (normal/reverse), and the subwoofer gain (+6 to -24).

Switchable Rear Channel/Subwoofer Speaker Output: The rear speaker outputs can be set to provide full range output with full fading capability, or they can be set to provide non-fading subwoofer (low-pass) output. When the rear speaker outputs are set to subwoofer mode, the rear preamp outputs also switch from full range to subwoofer outputs. When set for subwoofer operation, you can connect the rear speaker leads directly to two small 4-ohm passive subwoofers or a dual voice coil sub with 4-ohm voice coils. If you prefer to use a single 2-ohm subwoofer, you can connect the woofer to one set of speaker leads, leaving the other set of rear leads disconnected. The maximum output provided when a 2-ohm load is connected to one set of leads is 70 watts.

Radio Functions

Supertuner IIID AM/FM Tuner: The Supertuner IIID features Feed Forward Control, which avoids multi-path interference. This pre-detection of interference enables quick filter control and results in less distortion. In addition, the Supertuner IIID creates enhanced stereo during multi-path interference, unlike conventional tuners that collapse to mono. Digital processing reduces distortion, and improves Signal-to-Noise Ratio and stereo separation. Advanced analog technology improves signal processing sensitivity.

RDS: The Radio Data System (RDS) feature displays radio broadcast information such as artist, title, and album when listening to compatible AM/FM stations.

BSM (Best Stations Memory): The BSM (Best Stations Memory) function lets you automatically store the six strongest stations under preset buttons 1-6 of the currently tuned band. The tuner has 3 FM banks and 1 AM bank. You can store 6 presets for each bank giving you a total of 18 FM presets and 6 AM presets.

Local Tuning: Local seek tuning lets you tune in only those radio stations with sufficiently strong signals for good reception. There are 4 level of sensitivity for FM and two levels for AM. The higher settings allow reception of only the strongest stations, while lower settings let you receive progressively weaker stations.
