2.1. 구성 요소 및 제어

• HI-Z IN 1 / HI-Z IN 2: High impedance input jacks (1/4" TS) for connecting instruments, microphones, or other audio sources.
• HI-Z OUT 1 / HI-Z OUT 2: High impedance output jacks (1/4" TS) for routing the original signal to an amplifier or other stage equipment. These act as "thru" outputs.
• LO-Z OUT 1 / LO-Z OUT 2: Low impedance balanced XLR outputs for connecting to mixing consoles or audio interfaces.
• GROUND LIFT 1 / GROUND LIFT 2: Switches to disconnect the ground connection between the input and output, helping to eliminate hum and ground loop noise.
• STEREO/MONO SELECT: A switch to select between stereo (two independent channels) or mono operation (combining both inputs to a single output, typically LO-Z OUT 1).

3. 설정

Follow these steps to properly set up your Stagg SDI-ST DI Box:

1. 입력 소스 연결: Connect your instrument (e.g., guitar, bass, keyboard) or other audio source to the HI-Z IN 1 or HI-Z IN 2 jack using a standard 1/4" TS instrument cable. For stereo sources, use both inputs.
2. 연결하기 AmpLifier(선택 사항): If you wish to send the original signal to an on-stage amp리파이어, 연결하다 HI-Z OUT 1 or HI-Z OUT 2 잭에게 amplifier's input using another 1/4" TS instrument cable.
3. Connect to Mixer/Interface: 연결하다 LO-Z OUT 1 or LO-Z OUT 2 (XLR outputs) to the balanced XLR input of your mixing console or audio interface using standard XLR cables.
4. Select Stereo/Mono Mode:
   • For independent left and right channels (stereo), ensure the STEREO/MONO SELECT 스위치는 STEREO 위치.
   • To combine both inputs into a single mono output (typically LO-Z OUT 1), set the STEREO/MONO SELECT 로 전환하다 단핵증 위치.
5. 지상 리프트: 확인하십시오 그라운드 리프트 switches are initially in the "grounded" position (usually '0' or down). If you encounter hum or buzz, try engaging the ground lift switch ('I' or up) for the affected channel.

4. 사용 설명서

Once connected, the Stagg SDI-ST operates passively, meaning it does not require power and functions by transforming the signal impedance. Here are key operational considerations:

• 신호 흐름: The signal from your instrument enters via HI-Z IN. It is then split: one path goes to the HI-Z OUT (for an amplifier), and the other passes through a transformer to become a balanced, low-impedance signal at the LO-Z OUT (for a mixer).
• 접지 루프 제거: If you hear a low-frequency hum or buzz, it is often caused by a ground loop. Engage the 그라운드 리프트 switch for the channel experiencing the hum. This disconnects the ground path, which can resolve the issue. If the hum persists, ensure all equipment is properly grounded and try different power outlets.
• Mono vs. Stereo:
  • In STEREO mode, each channel (1 and 2) operates independently. Input 1 goes to Output 1, and Input 2 goes to Output 2.
  • In 단핵증 mode, both Input 1 and Input 2 signals are summed together and sent out through LO-Z OUT 1. LO-Z OUT 2 will typically be inactive or carry a duplicate mono signal depending on the internal wiring. Consult the mixer's input for optimal mono summing.
• 수동 작동: As a passive DI box, the SDI-ST does not boost the signal. The output level will be dependent on the input level. Ensure your source instrument has sufficient output.

5. 유지관리

Stagg SDI-ST DI Box is designed for durability and requires minimal maintenance.

• 청소: Use a soft, dry cloth to clean the exterior of the unit. Avoid using abrasive cleaners or solvents, as these can damage the finish.
• 저장: Store the DI box in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
• 손질: While the die-cast metal housing is robust, avoid dropping the unit or subjecting it to severe impacts, which could damage internal components.
• 케이블 연결: Always ensure cables are securely connected but avoid excessive force when plugging or unplugging, which can damage the jacks.
