Multi-track recorder ni (ga shadawn, AVID Pro Tools HDX) gaw 49.152MHz hpe lang nna 48kHz ahkying hpe shapraw ya ai majaw, sumla hkrung hte TV a matu galaw ngut ai hpang -hpang jahtum na aten hte maren sha galaw lu ai.

Master galaw ai arung arai ni (ga shadawn, Prism Sound ADA-8XR) gaw 44.1kHz hte 48kHz lahkawng yan hpe madi shadaw ra ai, aten lahkawng lang lang ai hkrang hpe hkap la ra ai.

· Nsen shapoi ai ladat ni:

Mixing console ni (ga shadawn, Lawo mc256) gaw 49.152MHz hpe kam hpa nna 48kHz signal ni hpe shapraw ya ai, nsen shapoi ai television nsen madang ni hpe hkan sa ai (ga shadawn, AES3).

2. Jai lang ai Electronic arung arai ni

· Hi-Fi Nsen Hkrang ni:

·

CD/SACD dum ai ni (ga shadawn, Esoteric K-01XD) ni gaw 45.1584MHz hpe lang nna 44.1kHz hpe grau kaja hkra dum ai.

Streaming decoder ni (ga shadawn, Linn Klimax DSM) gaw 49.152MHz hku nna 48kHz tsaw ai-resolution hpe madi shadaw ya ai.

· Nta kaw na sumla hkrung yu ai shara ni:

3. Mawdaw Nsen hte Hkrun Lam Hkrang Ni

· Mawdaw kata na Digital Signal Hkrang (DSPs) ni:

49.152MHz hpe lang nna 48kHz signal ni hpe shapraw ya ai, in-mawdaw n-gun jaw ai lam a majaw byin pru wa ai Jitter hpe shayawm ya ai.

· Hkamja lam hte seng nna, n-gun ja ai DAC nsen shaja ai jak ni (ga shadawn, iFi Nsen Hip-DAC):

Mobile jak ni hta 44.1kHz nsen npawt hpe grau kaja hkra galaw na matu, n-gun n law ai-45.1584MHz crystal ni hpe hpawng de da u.

## 3. Hpaji masa hpe shingdaw nna lata la ai lam hpe myit yu ra ai

Lata na matu hpaji jaw ai lam ni:

· Sumla hkrung hte Hkrang/Streaming Media: 48kHz series hte htuk manu hkra 49.152MHz hpe ahkyak shatai nna galaw na.

· Mahkawn ni hpe madat ai hte CD/SACD: 45.1584MHz hpe lata nna, kaja dik ai hkrang shapraw ai lam hpe galaw u.

· Multi-Format hte htuk manu ai ladat ni: -hkying aten lahkawng lang + FPGA n-gun rawng ai galai shai ai lam (ga shadawn, MSB Reference DAC) hpe hkap la ai.

49.152MHz hte 45.1584MHz gaw nsen hpaga lam hta digital nsen a "myit masin n-gun" rai nna, nsen n-gun kaba lahkawng hpe daw jau ai: sumla hkrung/htingnu/nsen shapoi ai media (48kHz series) hte mahkawn ni hpe shinggyin tawn da ai (44.1kHz series) ni hpe garan jaw ai. High-end jak ni gaw Jitter hpe shayawm kau ya nna, dual-clock architectures, ultra-low-nsen n-gun jaw ai lam ni, hte hkrak tup ai PCB layout ni hku nna san seng ai nsen hpe bai gram lajang ya ai. Htawm hpang de, resolution tsaw ai-nsen hte hka kata de shang wa ai nsen ni hpe masha law law chye wa ai hte maren, ahkying hpaji gaw ultra-low phase nois de matut nna rawt jat wa na re.
