안녕하세요?

1.

"사인파처럼 부드럽게 전압이 변하는것은 카드내 칩들(특히 아나로그 처리부의 op들)의 delay time 내에서 수용할수 있지만, 펄스성인경우엔 근접회로망에 어떤 영향을 주는게 아닐까 합니다"

전문가는 아니지만 충분히 일어날 수 있는 일이라고 생각됩니다. 음악용 장비이므로 단발성 펄스를 취급하는 상황에 대해서는 심각하게 고려하지 않았을 가능성이 있다고 생각되는데요.

또 다른 경우로 UA-4FX에 음을 가공하는 어떤 기능이 포함되어 있다고 상상하고 보통은 그것이 완벽한 0의 상태이어야 하는데 극미량의 누설이 일어나는 경우는 아닐까도... 상상해 보았습니다.

1. Mastering
Noise Suppressor/Enhancer/Multi-band Compressor-Limiter
2. Listening
Center Cancel/High Boost/Low Boost/Reverb
3. Performance
Voice-change/Amp-Simulator and Distortion/Chorus/Delay
4. Tube-amp simulator
Tube-Amp-Simulator/Multi-band Compressor-Limiter

더하여...

케이블, 접속재 속성과 상태에 전혀 문제 없고 사운드카드 입력과 이후 처리는 공용이고 8오움 더미부하 똑같고 앰프들 속성 대동소이하고 그런데 UA-4FX로 신호주입하면 Ringing 하고 F.G로는 아무 일 없다면 혹시...

펑션제너레이터 출력단자 임피던스가 50오움입니까? 600오움이던가가요? 가물가물. 그에 대비되는 UA-4FX(외장형 Midi 인터페이스)의 RCA 출력단자 임피던스는... 다르지 않을까요? 가용 임피던스 규격과 현실의 차 그리고 접속경로의 변수들이 종합되어 UA-4FX쪽에 모종의 오류(?)가 감지되는 경우, 그러니까 FG에도 살짝 담겨 있기는 한데 신호출력-신호입력 임피던스들 비율이 너무 작아서 들어나지 않는 경우를 상상해보고...

아? 그게 그건가요?

아무튼 저는 이런 대화가 재미있습니다. ^^

장치가 멋지군요. 글을 읽는 다른 분들을 위해서...

그런데 저는 이런 것을 DIY 장비로 응용할 생각을 전혀... 못했습니다.  취급 편의성만 생각해도 정말 좋은 아이디어네요. 굳이 빈티지 오디오 애널라이저를 구할 필요도 없을 만큼이요.



Roland UA-4FX Overview
The UA-4FX from Cakewalk is a USB audio and MIDI interface for Mac and Windows computers with a flexible amount of inputs and outputs, and a powerful built-in effects engine. It features a single XLR input that can handle professional microphones, a separate input for the direct recording of guitars and basses, RCA inputs for connecting devices (like a vinyl turntable with line-level outputs), and even a mini-plug microphone input for consumer mics.

Windows users can take advantage of the included Cakewalk Production Plus Pack software (the UA-4FX is fully compatible with Apple computers, however, the included software is not). The software bundle includes SONAR LE (a powerful audio recording and sequencing workstation), Dimension LE (a software instrument with over 400 sounds), and Project5 LE (virtual instrument host, audio recorder, and drum programming software). Windows users can also use the optical output for Dolby Digital or for DTS 5.1 Surround.

The back panel of the UA-4FX features stereo RCA outputs, two channels of optical S/PDIF digital audio I/O, and MIDI in and out ports. Whether you're recording rock musicians, acoustic performers, voice overs for video production, or creating electronic music, the UA-4FX offers excellent sound and ultra portability. The lush built-in effects and powerful software bundle really open the door for you to create dynamic sounding productions at a very budget-friendly price.
