프리 모델은 Focusrite ISA220입니다.

기존에 쓰던 오디오 카드는 그냥 라인입력이 있어서 프리앰프 캐논 아웃을
그냥 라인인에만 연결하면 됐었는데 오디오카드가 고장나서 몇년전에 쓰던
훈테크의 ADC/DAC 3000이라는 오디오카드를 꺼내서 먼지털고 연결해보니
여기엔 8채널에 모두 마이크프리가 내장 돼 있습니다.

당연히 오디오 카드 프리를 거치지 않고 마이크 ->프리앰프->오디오카드 로 연결하려고
하는데요.
오디오카드 전채널에 인서트 단은 달려 있습니다.
 
이 인서트 단에 어떻게 연결해야 한다는건 검색을 하다보니 대충 알겠는데
자세한 연결법과 어떤 케이블을 사용해야 하는지 알고 싶습니다.

마이크프리 아웃(캐논)->오디오카드 인서트(55모노)로 연결해 봤는데
아무 소리도 안나는군요.

지금 몇시간째 삽질 하고 있는데 답변 좀 부탁드립니다.ㅜ.ㅜ

오디오카드 메뉴얼에 연결 방법이 나와 있는것 같은데
전부 영어라 까만건 글씨라는것 밖에 모르겠습니다.
도와 주세요.ㅜㅜ

Every input channel of the ADC&DAC3000 has two inputs: one balanced XLR input (which you would normally use for microphones or for higher end audio equipment with balanced outputs and one unbalanced 1/4" input (which you would normally use for synthesizers, keyboards, etc.). You can use cables with both mono 1/4" and 1/4" TRS (Tip/Ring/Sleeve) connectors on the unbalanced inputs. Please note that you cannot use the XLR and 1/4" input simultaneously (independandly for each channel of course). As soon as a cable (or adapter) is plugged into the 1/4" input, the XLR input gets deactivated.
Every input channel on the ADC&DAC3000 has a separate insert connector. Inserts are usually used to process the analog input signal in an external effect processor before it gets converted by the ADC. You may be familiar with the concept of inserts, many mixing desks have inserts for example. If you never heard of effect inserts before, you might be a bit confused – don’t worry, inserts are a very nice addition to this product.
As mentioned, inserts allow you to use the microphone preamps of the ADC&DAC3000 for incoming signals, then run the signal through external hardware effects (e.g. a compressor/limiter) before the AD-converter processes the signal. In order to use the inserts, you need a so-called "insert-cable", sometimes called "Y-cable", with a 1/4" TRS connector on one and and two 1/4" mono connectors on the two other ends. If you have trouble to find such a cable, contact your local music retailer – they will certainly be able to help you. The TRS connector gets plugged into the insert connector of the specific channel of the ADC&DAC3000. The 1/4" connector that is connected to the "tip" of the TRS connector gets connected into the input of your effect processor. The 1/4" connector that is connected to the "ring" of the TRS connector gets connected to the output of your effect processor (the "sleeve" carries ground). So, every 1/4" insert connector is used for both, 'sending' and 'receiving' the signal. You need only one "insert-cable" per channel.
Note: You can even use the insert connectors of the ADC&DAC3000 as outputs (if you want to use the unit only as high quality preamp) or you can use the insert as line level input if you don’t want to use the gain control.
