large Double-Action Rotary Encoder Knob for maximum control over all music
search functions like QuickSearch for finding your songs or adjusting your
Angle Mounting: Alpine recommends mounting the iDA-X303 no
more that 35° above horizontal.
CEA-2006 Compliant: The
specifications given by Alpine for the built-in amplifier comply with the
CEA-2006 mobile amplifier power testing and measurement standards from the
Consumer Electronics Association. All manufacturers who comply with the standard
can display the CEA-2006 logo on their product.
- CEA-2006 Power Rating: 16 watts x 4-channel
- Max Power Output: 50 watts x 4-channel
Sound Quality: The
iDA-X303 uses clean digital connections and a 24-bit
Burr Brown DAC (digital-to-analog converter).
Bass and Treble Controls: The head unit features independent
Bass and Treble controls that allow you to adjust each setting +/-14 dB in 2 dB
steps. The center frequencies are adjustable (60, 80, 100, and 200 Hz for bass
and 10, 12.5, 15, and 17.5 kHz for treble) and the bass bandwidth is adjustable
(from narrow to wide in four steps).
Loudness: Loudness introduces a special low and high
frequency emphasis at low listening levels to compensate for the ear's decreased
sensitivity to bass and treble sound at low volume.
HPF: The high pass filter (HPF) removes the lower bass from the front
and rear speaker and line level outputs. HPF options are 80 Hz, 120 Hz, 160 Hz,
Subwoofer Pre-out: In addition to the front and rear 2-volt
preamp outputs, there is a dedicated 2-volt subwoofer preamp output with
variable level adjustment of 0 to 15. You can select either System1 or System2
for the desired subwoofer effect:
- Subwoofer System 1: subwoofer level changes according
to the main volume setting
- Subwoofer System 2: subwoofer level change is different
from the main volume setting; even at low volume settings, the subwoofer is
Power IC Off: When an external amplifier is powering all the
speakers in the system, you can turn the internal amp off, which will improve
the sound quality.
Interrupt Feature: When a device having the interrupt
feature (such as a cellular telephone) is connected to the receiver, the audio
signal will be automatically muted whenever the interrupt signal is received
from the device. The supplied wiring harness contains a pink/black Interrupt
lead that needs to be connected to the device's interrupt signal connection.
Sound Processing (with optional PXA-H100)
Imprint: With the addition of
the optional PXA-H100 Imprint box (500PXAH100, sold separately) and KTX-H100 tuning kit (500KTXH100, sold separately) a car's
inherent acoustic shortcomings can be overcome with the MultEQ feature. Imprint
also gives you much more sound adjustment flexibility as detailed below.
MultEQ: MultEQ, developed by Audyssey Labs, automatically
optimizes the audio for the listening environment inside your vehicle. The
Imprint kit includes the hardware, software, and microphone necessary to measure
multiple positions in the car and capture frequency and time domain information
from the vehicle's actual acoustical environment. Once the car's speaker
location delays are measured, along with the frequency peaks and dips caused by
the absorptive and reflective materials in the interior, MultEQ creates a set of
equalization filters to correct the frequency response and time domain problems
for each speaker in the vehicle. It also removes sound distortion caused by the
specific acoustical problems in the vehicle. This
optimizes the sound reproduction to the specific vehicle listening environment
with much greater precision than can be achieved using typical graphic or
parametric equalization. The result is a more accurate soundstage and smoother,
more natural sound optimized to match your vehicle.
Equalizer: 10 typical equalizer settings are preset for a
variety of musical source material. Select from Flat, Pops, Rock,
News, Jazz & Blues, Electrical Dance, Hip Hop & Rap, Easy Listening, Country,
and Classical. You can also save six custom EQ curves you create by
adjusting the parametric or graphic EQ:
- 5- Band Parametric EQ: The Parametric EQ allows you to
adjust the following 5 frequency bands in 1/3 octave steps from -6 to +6 dB
at a bandwidth Q factor of 1, 1.5, or 3
- Band 1:
20 Hz to 80 Hz
- Band 2:
50 Hz to 200 Hz
- Band 3:
125 Hz to 3.2 kHz
- Band 4: 315 Hz to 8 kHz
- Band 5:
800 Hz to 20 kHz
- 7-Band Graphic EQ:
The built-in Graphic EQ allows you to adjust the
following 7 frequencies from -6 to +6 dB
- Band 1:
- Band 2:
- Band 3:
- Band 4:
- Band 5: 2.5 kHz
- Band 6:
- Band 7: 17.5 kHz
Crossover: The active crossover can be used as a 2.2 channel (3-way;
low-pass subwoofer, band-pass midrange, high-pass tweeter) or a 4.2 channel
(2-way; high-pass front and rear, low-pass subwoofer). A crossover limits the
frequencies delivered to a given speaker, so you send only the frequencies for
which the speaker is well suited. The crossover adjusts the high pass filter or
low pass filter of each band along with the slope and output level. You can
adjust the following crossover settings:
- 4.2 Channel:
- High Pass Filter:
the front and rear outputs are individually adjustable; crossover from
20 to 200 Hz in 1/3 octave steps with a slope of Flat, 6, 12, 18 or 24
dB/oct, additionally you can adjust the output level from -12 to 0 dB
- Low Pass Filter: the subwoofer output can be stereo
or mono; crossover from 20 to 200 Hz in 1/3 octave steps with a slope of
Flat, 6, 12, 18 or 24 dB/oct, additionally you can adjust the output level
from -12 to 0 dB
- 2.2 Channel:
- Tweeter/High Pass
Filter: crossover from 1 kHz to 20 kHz in
1/3 octave steps with a slope of 6, 12, 18, or 24 dB/oct, additionally
you can adjust the output level from -12 to 0 dB
- Midrange/Band Pass
Filter: a band pass has both high pass
and low pass filters; HPF 20 to 200 Hz in 1/3 octave steps with a slope
of Flat, 6, 12, 18 or 24 dB/oct; LPF from 20 Hz to 20 kHz in 1/3 octave
steps with a slope of Flat, 6, 12, 18 or 24 dB/oct, additionally you can
adjust the output level from -12 to 0 dB
- Subwoofer/Low Pass
Filter: the subwoofer output can be
stereo or mono; crossover from 20 to 200 Hz in 1/3 octave steps with a
slope of Flat, 6, 12, 18 or 24 dB/oct, additionally you can adjust the
output level from -12 to 0 dB
The time correction feature delays the audio signal to
the speakers closer to the listener. This effectively creates a perception of
increased distance for those speakers. Time Correction allows the listener to be
placed at an equal distance from all speakers for optimum staging. You can
adjust the distance of each speaker and subwoofer (6-channel) to the listener
from 0 to 132.7 inches.
Media Xpander: The MX (Media Xpander) function makes vocals or instruments sound distinct by
restoring sound quality typically lost during recording or transmission; this
function helps restore audio information that becomes obscured when audio is
compressed. The MX function can be applied to all sources, except AM radio.
There are three settings and each source can have its own setting.
AM/FM Tuner: The Alpine
iDA-X303 features a built-in AM/FM tuner with manual, seek, and preset tuning.
