The attenuator typically connects in series with the speaker line. Ensure power to the amplifier is off before making any connections to prevent damage to the equipment or injury.
3. Інструкцыя па эксплуатацыі
The AtlasIED E408-250 features a simple rotary knob for adjusting the audio level. The knob has 10 distinct positions, labeled from 0 to 10, providing precise control over the attenuation.
- Adjusting Level: Rotate the knob clockwise to increase the sound level (less attenuation) and counter-clockwise to decrease the sound level (more attenuation).
- Attenuation Rate: Each step of the rotary switch provides an attenuation of 1.5 dB. This allows for fine adjustments to achieve the desired sound level in your environment.
- Non-Shorting Design: The switch is designed to be non-shorting, meaning it will not create a short circuit when transitioning between positions.
- No Stop: The rotary switch does not have a physical stop at position 0 or 10, allowing for continuous rotation. However, the attenuation range is defined by the 0-10 scale.
