MOSFET Amplifier: The DEH-33HD 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-33HD 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-33HD are
- 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-33HD 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.
Sound Retriever: The Sound Retriever automatically enhances

response curve to the original sound. There are two available levels of the
Sound Retriever effect.
EEQ (Easy EQ): The DEH-33HD 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.
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-33HD 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
Subwoofer Controls: When the subwoofer output is activated, 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
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.
