Marantz ud9004 Specification Guide

Calling the UD9004 a “disc player” understates its capabilities.  Yes, it will play virtually all 5” silver (or gold, or

green, or . . . ) discs you entrust to it.  There’s also an SD card reader slot behind the front panel’s drop down

door so you can enjoy photos or videos direct from your camera to your home theater system.  

What formats will the UD9004 handle?  The list is almost mind-numbingly long: Blu-ray (BD Video Profile 2 with

Bonus View support), BD-Java, BD-R/RE, DVD-V & -A, DVD+R/RW, DVD-R/RW, SA-CD (stereo and multi-channel),

CD, and CD-R/RW.  Let’s not forget MP3, WMA, JPEG, DivX version 6, Kodak picture CDs, or AVCHD files.  

But the number of formats is almost secondary to how well the UD9004 processes each for your enjoyment.  

On the audio side, you’ll find four individual circuit boards in a separate shielded chassis section.

This means that even complex layouts aren’t subject to the artifacts usually generated by 

closely-spaced signal traces.  And we’re using both HDAM and HDAM-SA2 modules to provide

inaudible stage-to-stage signal transfer.  The audio section’s power supply includes a copper-

shielded toroidal transformer to virtually eliminate spurious flux leakage inter-

ference.  If you think you’ve seen this approach before, you have – in the

Reference Series SA-7S1 Super Audio CD player!  The UD9004 adds a Pure

Direct mode that shuts off video and display circuits for absolutely 

crystalline sound.  XLR balanced outputs let you connect your UD9004 directly to a high 

quality preamplifier/processor such as our AV8003.  

Analog Devices’ SHARC 32-bit floating point processor handles Dolby TrueHD and DTS HD Master Audio decoding

while 192 kHz/32-bit D/A converters hand off decoded analog signals to the finely-tuned audio circuitry.  

Video processing is no less capable.  The Silicon Optix “Realta” processor provides pixel-by-pixel conversion for

high accuracy film presentation.  Even standard definition sources get full 1080p up-scaling thanks to the Realta’s

10-bit internal processor.  DNR (Dynamic Noise Reduction) acts on both SD and HD signals for ultra-smooth

reproduction.  For high quality analog output, there’s a 297 MHz/14-bit video DAC converter for Component

video signals and a dedicated 297 MHz/12-bit video DAC converter for S-Video and Composite video signals.  

A fine adjustment menu allows easy tweaking to suit your system if needed.  

You say watching movies is your forte?  Then let the UD9004’s HDMI output send a 24 fps (frames per second)

1080p signal to your compatible display.  This avoids the problems often associated with yesterday’s 3:2 pulldown

circuitry that matched film’s 24 fps rate to video’s 30 fps.  This preserves film’s “flavor” and subtle color shifts.
