PZ-G7 DSP AMPLIFIER USER’S GUIDE

PZ-C7 DSP Amplifier

This interface show the main GEQ & PEQ display by tuning 15 bands EQ parameters you can reset and bypass those parameters,and there are some useful parameters like Freq,Q, Gain,which clearly and accurately display.
a.You can tuning the high pass and low pass filter by HPS/LPS ,each channel is equipped with high pass filter and low pass filter.

b.Filter typies:butterworth,bassel and linkwitz-riley

c.The range of slope of filter (slope) is 6dB/Oct ~48dB/Oct,and the resolutionis 6dB/oct

d.When you press PEQ,you can tuning the EQ by drag or pull the points any of 1~15.

e.When you press GEQ,you can tuning the EQ by detail parameters you manually set it

flimiter is a circuit that allows signals below a specified input power or level to pass unaffected while attenuating (lowering) the peaks of stronger signals that exceed this threshold. Limiting is a type of dynamic range compression. Clipping is an extreme version of limiting.If you not familar ith this function and not know much about it just letit as default.

This interface you can control the main volume for each channels,phase front left/front right/Rear left/Rear right/Center/Sub.
g.you can set all 6 channels time delay parameters seperately.you can set the time delay unit CM/MS/inch,usually we recommend you use CM

Choose delay unit:ms/cm/inch
ms:0~20ms
cm:0~692cm
inch:0~272.44inch

Most importantly,please save tuning parmaters to 1-USER ~6-USER when you finish sound tuning every time.if you have local pc file saved before,just press the load button to upload the file.

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

piano| The range 27.5-48.5Hz affects the frequency, the tone becomes thinner as the frequency increases: 20-50H7 provides the °Pak 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,
• Bass:40Hz~150Hz,
• Midrange to Bass:150Hz~500Hz,
• Midrange:500Hz~2KHz,
• Midrange toTreble:2KHz~5KHz,
• Treble:TKHz~8KHz,
• Super Treble:8KHz~10KHz,

sense of instability
12K-16KHz| Lost luster| Golden splashes| Hairy, harsh
10K-12KHz| Boring, tarnished| Strong sense of metal| Light noise
8K-10KHz| dull| sound is smooth| sharp
6K-8KHz| dim| Transparent| Tooth sound heavy
5K-6KHz| vague| High definition| sharp
4K-5KHz| the sound is getting far| goodsense of loudness| the sound is getting close
4KHz| blurry| Good Penetration| Cough sound is heavy
2K-3KHz| hazy| Brightness is better| rigid
1K-2KHz| Loose, tone off| good sense of transparency| Jump sense
800Hz| Loose| Strong sense| guttural is heavy
500-800Hz| Shrinkage| The outline of the sound is good| The sound protrudes forward
300-500Hz| Empty sense| Voice power good| Phone sound color
150Hz-300Hz| Soft feeling| Sound intensity feeling good| stiff
100-150Hz| thin| Fullness increased| Turbid “hum”
60-100Hz| Weakness| Strong sense of depth| Low frequency resonancesound appears “hoc)”
20-60Hz| emptiness| Good sense of space| Low frequency resonance sound appears “hoo”

PLANNING YOUR INSTALLATION

It’simportant that you take the time to read this manual and that you plan your installation carefully,It’s very easy to damage expensive vehicle systems in modern automobiles,Never assume that you have found appropriate wires without consulting a reliable wiring diagram or without performing signal testing with proper test equipment,if you are uncomfortable or unfamiliar with reading diagrams or testing signals,plesae enlist the services of your authorized PUZU Audio dealer to perform the installation,PZ-C7 support universeal DSP cable and No- destructive wiring harness,Plug & Play,easy install it to your car audio system

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 a33ohm, 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
Exist buttom noise come from speaker when play DSP| Eusually it comes from your factory radio.the noise sound source come from it,after it get through DSP, noise is amplified,you can try adjust the button”Noise get threshold”from the software by PC computer.
