Cov khoom tseem ceeb ntawm lub tshuab hluav taws xob muaj xws li ntu kev tawm tswv yim, ntu tso zis, thiab kev ua haujlwm sab hauv
Tshooj lus
Cov tswv yim feem ntau suav nrog cov haujlwm hauv qab no:
Input Gain Control: Tswj cov theem nkag ntawm lub processor, feem ntau nyob rau hauv thaj tsam ntawm -6dB txog +dB.
Input EQ: Feem ntau 4-8 tag nrho parametric EQ yog siv, uas tuaj yeem kho qhov zaus, bandwidth lossis Q tus nqi, thiab nce.
Input Delay: ncua kev ua haujlwm ntawm lub teeb liab tawm tswv yim, uas yog tsim nyog rau kev hloov kho tag nrho ntawm tus neeg hais lus pab.
Kev hloov pauv ntawm cov tswv yim polarity: kho cov theem polarity ntawm lub teeb liab.
Cov zis seem
Qhov tso zis feem ntau suav nrog cov haujlwm hauv qab no:
Teeb liab Input Assignment Routing: Xaiv qhov input channel lub teeb liab yuav tso tawm.
High-pass filter (HPF) thiab low-pass filter (LPF): lim high-frequency thiab low-frequency signals.
Equalizer (EQ): Kho qhov zaus teb ntawm cov teeb liab tso zis.
Kev hloov pauv polarity: Kho qhov polarity ntawm cov teeb liab tso zis.
Tau Txais Kev Tswj: Kho cov theem ntawm cov teeb liab tso zis.
Delay: Ncua lub teeb liab tso zis.
Limiter pib-up theem: Tswj lub teeb liab lub zog tiv thaiv overload.
Internal processing module
Internal processing modules feem ntau suav nrog cov chips hauv qab no thiab ua haujlwm:
Op amps: xws li OPA 604, rau preamp amplification.
ADC chips, xws li PCM40, hloov cov teeb liab analog rau hauv cov teeb liab.
DSP chips: xws li ADI940, lub luag hauj lwm rau EQ nkhaus, suab nrov rooj vag, compression thiab lwm yam kev hloov ntawm cov input channel.
FPGA nti: tswj kev ua haujlwm thiab kev hloov pauv ntawm DSP nti.
Cov Cheebtsam no ua haujlwm ua ke los ua kom zoo rau kev ua haujlwm thiab kev sib kis ntawm cov suab paj nruag los ntawm kev ua kom lub suab processor ua haujlwm xws li nce kev tswj hwm, kev sib npaug sib npaug, kev ua haujlwm qeeb, polarity conversion, routing, lim, thiab lwm yam.
