Audio Section

Sound Quality: The iDA-X305S uses clean digital connections and a 24-bit Burr Brown DAC (digital-to-analog converter).

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: 18 watts x 4-channel (at 4 ohms, 20-20kHz, 1% THD)
• Max Power Output: 50 watts x 4-channel (200 watts total)

Head Unit Power Pack (optional): Add the KTP-445 (500KTP445, sold separately) Head Unit Power Pack to deliver 45 watts x 4-channel RMS of power. The KTP-445 is compact enough to install behind the iDA-X305S. It plugs in-line with the iDA-X305S's wiring harness so you don't even need additional wires.

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, and off.

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 still audible.

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: 63 Hz
  • Band 2: 150 Hz
  • Band 3: 400 Hz
  • Band 4: 1 kHz
  • Band 5: 2.5 kHz
  • Band 6: 6.3 kHz
  • 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

Time Correction: 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.
