서울 방배동에 서식하는 아카펠라 하는 장상인입니다.
여쭈어 볼 것이 있는데요.
아래에서 질문글을 올렸다시피, 빅놉의 문제인 줄 알았던 미세한 왼쪽 채널 소리 쏠림이.
DA 로 사용하고 있는 PSX100 의 문제임을 알게 되었습니다.
단순하게 Psx100 의 칼리브레이션을 해주면 되니, 돈 들일 필요 없이 모니터 컨트롤러의 수리 또는
기기 변경이 없게 되어서 무척 기쁜데요.
문제는 PSX100 의 앞 패널에 있는 D/A Level 을 일자 드라이버로 조절 해보아도
해결이 되지가 않네요. (조그맣게 일자 드라이버로 돌리게 되어있습니다.)
혹시 뒤의 리어패널에 있는 여러개의 내리고 올릴수 있는 조그마한 버튼들을 조정해 주어야
앞 패널의 D/A Level or A/D Level 이 조정 가능한 것인지 궁금합니다.
아무쪼록 PSX-100 의 칼리브레이션 방법에 대해 알려주시면 감사하겠습니다.
부탁드립니다.

How do I calibrate the PSX-100 A/D and D/A?

Q: How do I calibrate the PSX-100 AD and DA?
A: The PSX-100 has can be calibrated to a level between -20 and -11 dBFS. To enter calibration mode, press and hold the SoftLimit button until it begins to flash. At that point, the meters are reflecting the "zoom meter" mode with the bottom LED corresponding to -20 and the top LED to -11 dBFS. Insert a +4 analog tone into the analog inputs and press the Meter mode to reflect A/D metering. By default, the level of calibration from the factory is -16 dBFS. To calibrate for a -12 dBFS, turn the A/D calibration trimpots. As the level increases one LED, which equals one dBFS, the over light will turn on indicating you have achieved the next level up in dBFS. Each LED you light up will cause the over light to come on, and as you increase the gain, the over LED will go off until the next LED is lit up. When you get to the desired level, stop as soon as the over LED lights up. On the meter, -10 equals -16 dBFS, -6 equals -14 dBFS, and -2 equals -12 dBFS. For the D/A calibration, a digital signal equal to the A/D calibration must be sent to one of the digital inputs. Put the PSX-100 into the D/A metering mode. Take the analog outputs of the PSX-100 and feed it into a device with analog metering. Since digital level can not be changed, only the analog output is being reflected. Turn the D/A trimpots so that the external analog metering hits 0.
