2.1. Компоненте и контроле

• 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. Подешавање

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

1. Повежите извор улаза: 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. Повежите се са AmpЛифиер (опционо): If you wish to send the original signal to an on-stage ampлифиер, спојите HI-Z OUT 1 or HI-Z OUT 2 џак за твој amplifier's input using another 1/4" TS instrument cable.
3. Connect to Mixer/Interface: Повежите 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. Изаберите стерео/моно режим:
   • For independent left and right channels (stereo), ensure the STEREO/MONO SELECT прекидач је у СТЕРЕО положај.
   • To combine both inputs into a single mono output (typically LO-Z OUT 1), set the STEREO/MONO SELECT пређите на МОНО положај.
5. Приземни лифт: Осигурајте ГРОУНД ЛИФТ 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. Упутство за употребу

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:

• Ток сигнала: 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).
• Елиминација уземљивачке петље: If you hear a low-frequency hum or buzz, it is often caused by a ground loop. Engage the ГРОУНД ЛИФТ 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 СТЕРЕО mode, each channel (1 and 2) operates independently. Input 1 goes to Output 1, and Input 2 goes to Output 2.
  • In МОНО 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.
• Passive Operation: 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. Одржавање

Тхе С.tagg SDI-ST DI Box is designed for durability and requires minimal maintenance.

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