transmission, and a large-sized high power capacitor for deep bass sound.
Dynamic Reality Amp: The CDX-GT56UI is equipped with Sony's Dynamic
Reality Amp to produce 3 dimensional sound staging for more realistic sound
inside your vehicle.
CEA2006 Compliant Amplifier: The power specifications for
the Sony CDX-GT56UI 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
CDX-GT56UI are as follows:
- Continuous Power Output: 17 watts RMS x 4 channels (at 4 ohms,
20Hz-20kHz, 1% THD-N)
- Peak Power Output: 52 watts x 4-channels (208 total watts)
Switchable Rear/Subwoofer 2V Preamp Output: The Sony CDX-GT56UI is equipped with a switchable rear/subwoofer 2-volt
preamp output for connecting a full-range or subwoofer amplifier.
Subwoofer Controls: When the unit's subwoofer output is
activated, the preamp output becomes non-fading & a low pass filter is activated
with a selectable cut-off frequency of 50Hz, 60Hz, 80Hz, 100Hz, 120Hz, or Off.
You can also adjust the slope (1/2/3) of the low-pass crossover. You can adjust
the subwoofer preamp output's volume level independently from the head unit's
volume control from -10 to +10 in 1dB increments. In addition, you can select
the phase of the subwoofer output from Normal or Reverse.
High-Pass Filter: The front & rear speaker outputs offer a
selectable high-pass crossover frequency of 50Hz, 60Hz, 80Hz, 100Hz, 120Hz, or
Off. You can also adjust the slope (1/2/3) of the high-pass crossover.

types - Xplod, Vocal, Edge, Cruise, Space, Gravity, Custom, or Off (Flat).
The Custom EQ7 mode allows you to make your own equalizer settings. You

(63Hz), Band2 (160Hz), Band3 (400Hz), Band4 (1kHz), Band5 (2.5khz), Band6
(6.3khz), and Band7 (16.0kHz).
- Listening Position: This unit can change the
localization of sound by delaying the sound output from each speaker to suit
your position, and simulate a natural sound field with the feeling of being
in the center of it wherever you sit in the car. You can choose from Front
Right, Front Left, Front Center, or Off. You can also set the subwoofer
distance of the subwoofer to Near, Normal, or Far
- RBE (Rear Bass Enhancer): RBE enhances the bass sound
by applying the low-pass filter setting to the rear speakers. This function
allows the rear speakers to work as a subwoofer even if there is no
subwoofer connected.
- Dynamic Loudness: Dynamic Loudness refers to
compensating for volume level & signal gain.
- DM+ Advanced: DM+ Advanced improves digitally
compressed sound by restoring high frequencies lost in the compression
process (works only for USB).

analyzes each track's playback level & adjusts the output level to optimize
transitions between tracks & sources.
Beep Tone: The in-dash head unit provides an audible beep to
confirm button operation. This function can be turned On or Off.
