CD/MP3 receiver with CD changer controls
Our take on the Sony CDX-F7705X by Crutchfield's Robert Ferency-Viars
Sony's CDX-F7705X CD/MP3 receiver is an amplifier pleaser! Three sets of 4-volt preamp outputs send a strong, clean signal to your external amplifiers. Built-in high-pass and low-pass filters ensure that the appropriate frequency ranges are sent to the correct amplifiers, so you get the best possible performance from your system.
You'll have total control of the sound with Sony's EQ7. Seven preset sound curves give you quick, convenient tuning, or tweak the 7-band equalizer when you want the sound to be perfect. And DSO "raises the roof" on the soundstage, especially if your speakers are near the floor.
Slide in an MP3 disc, flip up the faceplate, and the song titles and other text information scroll across the detailed, fine-dot fluorescent display. Built-in BBE MP processing restores brilliance and focus to your MP3 files, while the spectrum analyzer gives you a visual account of the music.
Add a compatible (XM Radio tuner and go wild with the innovative, diverse programming of XM Satellite Radio (antenna and subscription also required). If you're not adding XM or a CD changer, then the changer port on the rear of the deck can be used as an auxiliary input for your portable audio player. Whatever you listen to, the built-in 4-way high power amplifier will make it sing.

Drive S: The CDX-F7705X 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 an improved suspension to resist shocks, a new motor that draws less power, and a fast new low-current pickup that improves durability and CD playback accuracy. The new 52W x 4 S-MOSFET Power IC produces clearer, more accurate sound, less distortion, and a higher signal-to-noise ratio than previous designs.
Full-Motion Fluorescent Display: 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. The resolution of the display is 130(H) x 39(V). Using the Image button on the face of the unit, you can cycle through 5 wallpaper displays, 5 spectrum analyzer displays, and 3 motion displays. Using the Auto Image function, you can randomly show the different displays, or you can step repeatedly through the spectrum analyzer displays or the motion displays.
MP3 Playback: This unit can play MP3 files recorded on CD-ROM, 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 MP3 playback, the unit displays any recorded ID3 Tag information.
BBE MP: When playing back MP3 files, the BBE MP circuit recovers and recreates harmonics, restoring the detail, warmth and nuances that existed in the original recording.
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.
EQ7: You may select one of the following EQ presets: Xplod, Vocal, Club, Jazz, New Age, Rock, or Custom. For each preset, you can adjust the following frequencies: 62Hz, 157Hz, 396Hz, 1kHz, 2.5kHz, 6.3kHz, and 16kHz. The level of each frequency can be adjusted from +10dB to -10dB in 1dB increments.
Source Tone Memory: Each source (AM/FM/CD/Changer) can store its own EQ7 levels.
XM Satellite Radio Controls: This unit can control an optional Sony XM tuner. The optional tuner, along with an antenna and subscription, will allow you to receive XM Satellite Radio. XM Satellite Radio programming features up to 100 channels of digital-quality music, news, talk, sports, entertainment, and children's programming.
SSIR-EXA Adaptive Reception: The SSIR-EXA tuner is equipped with "Adaptive Reception". The Adaptive Reception feature has two modes ("IF Auto" and "IF Wide") for optimizing FM reception. The "Wide" mode decreases the tuner's selectivity but results in better frequency response. The "IF Auto" mode automatically adjusts the tuner for a good balance between frequency response and minimum station-to-station interference. The Adaptive Reception feature cannot be turned off.
Best Tuning Memory (BTM): This feature selects stations with the strongest signals within the selected band and stores them in order of their frequency.
Station Memo: You can assign a name of up to 8 characters in length to each tuner preset station. Station Memos can be used with the List-up function to locate a station.
4 V Mono Subwoofer Preamp Outputs: In addition to the 4 V front and rear preamp outputs, this unit includes one set of 4 V 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.
High-pass Filter: The front and rear preamp outputs have a selectable high-pass filter that may be set to 78Hz, 125Hz, or off.
Low-pass Filter: The subwoofer preamp outputs have a selectable low-pass filter that may be set to 78Hz, 125Hz, or off.
Aux Lite Auxiliary Input: The CDX-F7705X 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.
Note: If a CD/MD changer is connected to this receiver, you will not be able to connect an auxiliary source without an adapter (158XA300).
Dimmer: 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 to "On".
Note: For this feature to work, the unit's illumination wire must be connected to your vehicle's dash lights wire.
45-Degree Installation: For flexibility of installation, this unit can be mounted between 0 (horizontal) and 45 degrees.
Wired Remote 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 use the menu system to change the control direction of the remote, depending on which side of the steering wheel you choose to mount the remote.
Compatibility: This unit is compatible with Sony Unilink CD and MD changers. In addition, this unit can control compatible Sony Mobile Memory Stick players.
Multiple Changer 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 source selector.
CD/MP3 Changer Controls: When a CD/MP3 changer is connected to this unit, you can perform the following functions: disc skip, track skip, audible track search, album skip, track repeat, album repeat, disc repeat, disc random, album random, changer random (plays all the tracks in the current changer in random order), and all random, which plays the tracks from the disc loaded in the head unit and all connected changers in random order.
CD Text/MD Memo Display: When used with a compatible CD changer and a CD Text encoded CD, this unit will display the CD Text information. When using a compatible Sony MD changer, this receiver can display disc and track names that have been prerecorded on MDs.
Disc Memo: When a changer with the Custom File function is connected to this unit, you can enter names, up to 8 characters long, into memory for up to 110 discs. After a disc has been given a custom title, you may search for the disc, by title, using the List-up function.
Auto Scroll: If the text being displayed exceeds 12 characters and the Auto Scroll function is on, the information will automatically scroll across the screen.
Display Illumination/Clock Display: 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.
