Cov txheej txheem suab, tseem hu ua cov txheej txheem digital, xa mus rau kev ua cov teeb liab digital, thiab lawv cov qauv sab hauv feem ntau yog tsim los ntawm cov khoom nkag thiab cov khoom tso zis. Yog tias nws hais txog cov khoom siv kho vajtse, nws yog cov voj voog sab hauv uas siv cov khoom siv ua suab digital. Qhov sib piv ntawm lub teeb liab thiab suab nrov siab thiab muaj peev xwm tiv thaiv kev cuam tshuam zoo.

Cov txheej txheem suab digital yog piv rau cov kab ke suab analog. Lub kaw lus suab analog thaum ntxov tshaj plaws, lub suab nkag mus rau hauv lub tshuab sib xyaw los ntawm lub microphone. Kev txwv siab, kev sib npaug, kev txhawb nqa, kev faib zaus,lub zog amplifier, lub tso suabLub tshuab ua haujlwm digital audio sib xyaw ua ke cov haujlwm ntawm txhua yam khoom siv analog, thiab kev sib txuas lub cev tsuas yog lub microphone, lub tshuab ua haujlwm digital audio, lub zog amplifier, thiab lub tso suab. Tus so yog ua haujlwm hauv software.

(Cov tswv yim/tso zis channel: 3 Tswv yim/6 Tso zis;

Txhua qhov kev ua haujlwm ntawm cov channel input: mute, nrog rau kev tswj hwm mute cais rau txhua channel)

Cov haujlwm tseem ceeb ntawm lub processor suab yog:

1. Feem ntau, qib nkag ntawm lub processor tswj tuaj yeem hloov kho tau hauv qhov ntau ntawm kwv yees li 12 decibels.

2. Kev sib npaug ntawm cov tswv yim: Feem ntau kho qhov zaus, bandwidth, lossis Q tus nqi, nce.

3. Kev ncua sij hawm nkag: Siv qee qhov kev ncua sij hawm rau lub teeb liab nkag, thiab feem ntau kho qhov kev ncua sij hawm tag nrho thaum lub sijhawm ua haujlwm pabcuam.

4. Kev siv hluav taws xob: nws muaj peev xwm muab faib ua ob ntu: qhov nkag thiab qhov tso zis. Nws tuaj yeem hloov qhov polarity theem ntawm lub teeb liab ntawm qhov zoo thiab qhov tsis zoo.

5. Kev Teeb Liab Tawm Tswv Yim (ROUNT): Lub luag haujlwm yog kom cov channel tso zis no xaiv tau qhov channel nkag twg los txais cov teeb liab los ntawm.

6. Band pass filter: kuj muab faib ua ob hom: high pass filter thiab low pass filter, siv los kho qhov siab thiab qis zaus ntawm cov teeb liab tso zis.

Lwm cov haujlwm ntawm lub processor suab:Lub tshuab ua suab kuj tseem tuaj yeem pab cov neeg siv tswj cov suab paj nruag lossis suab paj nruag, tsim cov suab sib txawv hauv ntau qhov xwm txheej, ua rau muaj kev xav tsis thoob ntawm cov suab paj nruag lossis suab paj nruag, thiab tseem tswj ntau lub luag haujlwm suab ntawm qhov chaw.lub tshuab ua suabmuaj ntau yam haujlwm sib xyaw ua ke, ntawm cov uas qhov kev faib zaus yog qhov tseem ceeb heev. Kev faib zaus tuaj yeem muab kev hloov kho raws li cov ntaub ntawv zaus sib txawv ntawm lub kaw lus suab hauv cov xeev ua haujlwm sib txawv. Qhov kev ua haujlwm no ua raulub tshuab ua suabkom hloov kho tau rau ntau yam khoom siv suab, tsuav yog cov khoom siv suab ua haujlwm tau zoo. Kev tshawb nrhiav lub processor suab txuag tau qhov kev ua tiav ntawm cov ntaub ntawv suab thiab sib txuas lus rau cov khoom siv suab
