The CDX-RA700 features the Drive S chassis platform. Drive S includes the CD
mechanism, audio stages, 12 V power supply, and tuner section. The CD mechanism
includes a suspension to resist shocks, a motor that draws less power, and a
fast low-current pickup that improves durability and CD playback accuracy. The
52W x 4 S-MOSFET Power IC produces clearer, more accurate sound, less
distortion, and a higher signal-to-noise ratio than previous designs.
Satellite Radio Ready: You can
connect a satellite radio tuner to the CDX-RA700 in a couple of ways. The unit
is directly compatible with the SIRIUS SIR-SNY1 Satellite Tuner for Sony (item #
607SIRSNY1). The Terk XMDirect universal XM Satellite Radio tuner (209XMD1000)
can be connected to and controlled by the head unit when used with the XMDirect
Smart Adapter for Sony (209SON110).
Note: In addition to
the optional satellite tuner, you will also need the proper antenna and
a subscription to SIRIUS or XM Satellite Radio.
The unit's fluorescent display technology gives you better resolution than
conventional LCDs, and lets data transition faster for smooth, clean, solid
movement of graphics. Using the Image button on
the face of the unit, you can cycle through 3 wallpaper displays, 5 spectrum
analyzer displays, and 3 motion displays. Using the Auto Image function, you can
step repeatedly through the spectrum analyzer displays, motion displays, or all
24-Bit Burr Brown D/A Converter:
This digital-to-analog converter uses Advanced Segment architecture to
achieve improved dynamic performance and resistance to clock jitter.
Additionally, the digital-to-analog converter features a zero-bit detection
circuit, which senses when all bits are low on a CD, and mutes the output for
improved S/N ratio.
ATRAC CD Playback: The
CDX-RA700 plays ATRAC3plus/ATRAC3 files recorded on CD-R and CD-RW discs. Each
ATRAC disc can have a maximum of 255 groups and 999 files.
This unit can play MP3/WMA files recorded on CD-R and CD-RW discs in ISO9660
Level 1/Level 2, Joliet, and Romeo formats. Each disc should have a maximum of
150 folders and 300 files/folders. During playback, the unit displays any
recorded ID3 Tag information.
EQ3: You may select one of the
following EQ presets: Xplod, Vocal, Edge, Cruise, Space, Gravity, or Custom. For
each preset, you can adjust the following frequencies: Low (60 or 100 Hz), Mid
(500 Hz or 1 kHz), and High (10 or 12.5 kHz). The level of each frequency can be
adjusted from +10 dB to -10 dB in 1 dB increments.
When playing back MP3 files, the BBE MP circuit recovers and recreates
harmonics, restoring the detail, warmth and nuances that existed in the original
Dynamic Soundstage Organizer
(DSO): Sony's Dynamic Soundstage
Organizer uses proprietary circuitry to induce subtle phase shifts, simulating a
sound source that is placed higher than the actual speakers in the vehicle. For
example, when the DSO function is used in a vehicle equipped with speakers
mounted low in the front doors, it creates virtual speakers in the dash to raise
the soundstage. This unit offers three levels of DSO, each with a larger and
higher soundstage. You can store the DSO setting for each source.
Best Tuning Memory (BTM):
This feature selects stations with the strongest signals within the selected
band and stores them in order of their frequency.
2V Mono Subwoofer Preamp
Outputs: In addition to the 2V front
and rear preamp outputs, this unit includes one set of 2V mono subwoofer preamp
outputs. Although there are two female RCA subwoofer outputs, the same signal is
carried by both connections. A low-pass filter (see below) can be used to filter
high frequencies from the signals output by the subwoofer outs.
Filter: The subwoofer
preamp outputs have a selectable low-pass filter that may be set to 78Hz, 125Hz,
Auxiliary Input: The
CDX-RA700 has an auxiliary input on the rear panel, allowing you to connect a
separate audio source, such as a portable MiniDisc or MP3 player, or the audio
output from a mobile/portable DVD player. In the past, Sony receivers required a
separate adapter, however, this unit's "Aux Lite" input allows you to directly
connect the auxiliary unit to the receiver's stereo RCA input jacks.
If a CD/MD
changer is connected to this receiver, you will not be able to connect
an auxiliary source without an adapter (158XA300).
This unit is equipped with a wire that
Sony calls an illumination lead, however, it acts as a dimmer lead. When the dimmer mode is set to "Auto" and the illumination
lead receives power, the display dims to a preset level. The display brightness
is not affected by the vehicle's dimmer control. Also, the dimmer feature may be
turned off, so dimming does not take place when the illumination lead receives
power. You may choose to dim the display at all times by setting the dimmer mode
For this feature to work, the unit's illumination wire must be connected
to your vehicle's dash lights wire.
For flexibility of installation, this unit can be mounted between 0 (horizontal)
and 45 degrees.
Compatibility: In addition to the
supplied wireless remote, the receiver can be controlled by an optional wired
rotary commander (item 158RMX4S). Once the wired remote is connected, you can
change the control direction of the remote, depending upon which side of the
steering wheel you choose to mount the remote.
This unit is compatible with Sony Unilink CD/MP3 and MD changers.
Optional Auxiliary Input: You
can connect an auxiliary audio device (such as a portable digital memory player,
cassette, MiniDisc, or VCR) when used with the optional XA-300 Unilink Auxiliary
Input Adapter. The XA-300 uses the Unilink and Bus Audio inputs on the back of
the receiver, and allows you to connect an optional CD/MD changer in addition to
the auxiliary audio source.
Control: A maximum of 5 CD
changers, 5 CD/MP3 changers, or 5 MD changers may be connected to this receiver.
When connecting CD, CD/MP3 and MD changers, you may connect up to a total of 7
changers (but there must not be more than 5 of one type of changer). When
connecting more than one changer to this receiver, you must use the Sony XA-C30
Pressing the Off button once will turn off audio output, but the clock display
and face/button illumination remain on. This makes the clock display and
face/button illumination "Keyed" instead of "Unit On" only. To turn the unit off
completely, you must press the Off button for two seconds.
Note: When installing in a vehicle without an accessory power
wire at the radio location, you must turn the radio completely off (this
defeats keyed operation), or you may wire the accessory power wire of
this radio to an alternate source of accessory power to retain keyed
clock and face/button illumination operation.
