4. סעטאַפּ און ייַנמאָנטירונג

The Radial StageBug SB-5W is designed for installation into a standard electrical junction box. Professional installation is recommended.

4.1 גשמיות ינסטאַלירונג

1. Ensure power is off to the junction box before beginning installation.
2. Mount the SB-5W into a standard electrical junction box using appropriate screws.
3. Secure the faceplate to the unit.

4.2 פֿאַרבינדן אַרייַנגאַנג קוועלער

The SB-5W accepts two types of stereo input connections: a 1/8-inch (3.5mm) TRS stereo jack and a pair of RCA (Left/Right) jacks.

1. Connect the balanced audio cables from the SB-5W's output terminal blocks to the appropriate input channels on your mixing console or audio interface.
2. Ensure correct polarity and channel assignment (Left/Right).

5. Operating the SB-5W

The SB-5W features a level control, a mono fold-down switch, and a ground-lift switch on its front panel for easy access and signal management.

5.1 Level Control

The large knob labeled LEVEL adjusts the output volume of the stereo signal. Rotate clockwise to increase the level and counter-clockwise to decrease it. Start with the level at minimum and gradually increase it to achieve the desired output volume without clipping at your mixer.

5.2 Mono Fold-Down Switch

The button labeled MONO, when engaged, sums the left and right stereo input signals into a single mono output. This is useful when feeding a mono sound system or when you need to check for phase issues in a stereo mix. When disengaged, the unit operates in stereo.

5.3 Ground-Lift Switch

The button labeled הייבן activates the ground-lift function. This switch disconnects the audio ground from the chassis ground, which can help eliminate hum and buzz caused by ground loops between the source device and the connected audio system. If you experience hum, try engaging this switch. If the hum persists, ensure all equipment is properly grounded and check cable connections.

6. וישאַלט

The Radial StageBug SB-5W is a robust and passive device designed for long-term reliability with minimal maintenance.

• רייניקונג: Periodically wipe the unit's surface with a dry, soft cloth to remove dust. Avoid using abrasive cleaners or solvents, as these can damage the finish and labels.
• דורכקוק: Occasionally check all cable connections for secure fit. Ensure the unit is free from physical damage.
• סוויווע: Maintain a stable environment, avoiding extreme temperatures, humidity, or direct sunlight, which can shorten the lifespan of electronic components.
