Bass Engine: Bass Engine functions provide control over your system, so you can tailor the sound to your personal tastes. Bass Engine includes the following functions:
* Bass Control:
o Bass Center Frequency: 60Hz, 80Hz (default), 100Hz, or 200Hz
o Bass Band Width (Q): Q1 (narrow), Q2, Q3, or Q4 (wide)
o Bass Level: -7 to +7 (-14dB to +14dB in 2dB steps)
* Treble Control:
o Treble Center Frequency: 10kHz (default), 12.5kHz, 15kHz, or 17.5kHz
o Treble Level: -7 to +7 (-14dB to +14dB in 2dB steps)
* High Pass Filter (HPF): speaker level and preamp outputs (other than the subwoofer output) have a selectable crossover (HPF); off (default), 80Hz, 120Hz, or 160Hz
* Loudness: on/off
* Defeat On/Off: reset the unit to its factory default bass and treble settings by turning the Defeat function on
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.
Subwoofer Pre-out: In addition to the front and rear preamp outputs, the CDA-9884 has a dedicated subwoofer output with a variable level of 0 to +15. When the subwoofer is on, 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
Imprint: With the addition of the optional PXA-H100 Imprint box (item number 500PXAH100) and KTX-H100 tuning kit (item number 500KTXH100) 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.
Equalizer: 10 typical equalizer settings are preset at the factory for a variety of musical source material. You can select from - Flat, Pops, Rock, News, Jazz & Blues, Electrical Dance, Hip Hop & Rap, Easy Listening, Country, and Classical. The head unit will also save six custom EQ curves you create by adjusting the units built-in EQ. Choose the parametric or graphic EQ:
* 5- Band Parametric EQ: The built-in 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
o Band 1: 20 Hz to 80 Hz
o Band 2: 50 Hz to 200 Hz
o Band 3: 125 Hz to 3.2 kHz
o Band 4: 315 Hz to 8 kHz
o 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
o Band 1: 63 Hz
o Band 2: 150 Hz
o Band 3: 400 Hz
o Band 4: 1 kHz
o Band 5: 2.5 kHz
o Band 6: 6.3 kHz
o 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:
o 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
o 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:
o 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
o 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
o 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.
