BEFOR USE PUZU PZ-C7SOFTWARE YOU NEED TO KNOW BASIC SOUND PARAMETERS OF DIFFERENT MUSIC INSTRUMENTS PERFORMANCE,S0 YOU CAN BETTER UNDERSTAND HOW TO TUNING THE SOUND!

piano| The range 27.5-48.5Hz affects the frequency, the tone becomes thinner as the 1
frequency increases; 20-50Hz provides the peak frequency
---|---
Saxophone| 600-2Khz affect the brightness, enhance the frequency can make the sound color clear
guitar| improve 100-300Hz can make the sound much more fullness; enhance 2k- 5KHz can
increase the tone performance
Bass guitar| 60-100Hz bass fullness; 60-1 KHz impact intensity, 2.5Khz is plectrum audio
electric guitar| 240H is the fullness frequency, 2.5KHz is the brightness frequency; plectrum is 3K-4KHz
Electric bass| 80-240Hz is fullness frequency; 600-1 Khz impact intensity; 2.5KHz is plectrum audio
tambourine| 200-240Hz is the resonance frequency; 5KHz affect the presence
Snare drum| 240Hz affect fullness; 2KHz impact loudness; 5KHz affect plucked audio
Bass drum| 60-100Hz is the bass force frequency; 2.5KHz is the percussion sound frequency
big drum| 60-150Hz is the intensity of frequency; affect fullness

TIPS

  • Super bass:20Hz~40Hz,

Work indicator light does not shine,no sound| Please check if the tail has been properly connected, check the original car with or without amplifier or modeified amplifier
The original car host and the machine can’t get power on| Check whether the original power cord is connected, the original car with original car host shell,restore the original car position
there is a “pump” sound when connected the DSP with subwoofer| Plese connect the blue wire of the harness cable to your car subwoofer’s REM plug
All connection well and there is no sound come from speaker after few seconds sound come again from speaker.or there is a “zizizi” or “dididi”sounds come from speaker.| You car with speaker detection function. Solution:Between the 4 high-level input ports of the DSP power amplifier and the 4 high-level output ports of the host, each interface is connected in parallel with a 33 ohm, 10W cement resistor.
DSP can not get power on when choose”Host”start up| switch to “ACC” start up and then connect the red line of the harness cable to your car ACC line
