Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Drive S: The Drive S chassis
platform is designed to resist the harsh environment of a vehicle and produce a
superior signal-to-noise ratio, giving you clearer, more accurate sound.
DSSA: You can adjust the sound
stage and tone balance to best serve a particular seat in the vehicle using the
Driver's Sound Stage Adjustment (DSSA). The DSSA control is preset for the front
left or front right seat. Once you have chosen a particular seat setting, you
can further manually adjust the balance and fader settings.
Front Panel Aux Input: The
CDC-X304 features a 1/8" stereo minijack on the front panel to allow you to
connect a portable cassette, MiniDisc, or MP3 player. The volume of the
connected auxiliary source unit can be controlled by the receiver.
Switchable Rear Preouts: This
unit has one pair of preamp outputs that can be switched between "Rear" and
"Subwoofer." When the preouts are switched to "Subwoofer" they are not affected
by the fader control, plus you can independently select the cutoff frequency of
the low-pass filter (78Hz, 125Hz, or Off), and adjust the volume of the
subwoofer (+10 to -10 and Attenuate).
H-Bass: Instead of a loudness
control, this unit is equipped with an H-Bass function. Conventional bass boost
circuits also affect the mid-bass and midrange, resulting in a muddy, "boomy"
sound. H-Bass provides true deep bass enhancement for a dynamic bottom end that
does not destroy the clarity of vocals and other mid-frequency content. H-Bass
enhancement can be switched on or off, and does not affect the preamp output
signal when it is switched to "Sub."
Equalizer: The receiver has 7
preset equalizer curves for different music types: Hip-Hop, Vocal, Club, Jazz,
Pops, Rock, and Custom. Once you have selected a preset EQ curve, you can
further adjust the low (60Hz), mid (1kHz), and high (10kHz) bands from -10 dB to
Source Level Adjuster: The
relative level of each source (FM/AM/CD/AUX) may be adjusted, from -6 dB to +6
dB in 1 dB steps, and the setting will be retained in memory. The level of each
source can be set so there won't be drastic leaps in volume when changing from
one source to another.
Dimmer: You can lower the
brightness of the display and button illumination by switching on the dimmer in
the menu. The dimmer function is controlled manually, and is not affected by the
vehicle's headlight circuit.
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.
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.
