Frequently Asked Questions - AT100-PARM ATLAS
What is an attenuator used for?
An attenuator reduces the power of an audio signal without affecting its waveform. This allows you to control speaker volume while maintaining a consistent impedance match with the amplifier.
What is the maximum power handling of the AT100-PARM?
The AT100-PARM can handle up to 100 watts RMS, making it suitable for most home and commercial audio systems.
Can I use this attenuator with 70V speakers?
Yes, the AT100-PARM is compatible with both 25V and 70V distributed audio systems, as well as standard 8-ohm speakers.
How do I install the attenuator?
Connect the amplifier output to the line inputs, then connect the speaker wires to the output terminals. Ensure the power is off during installation. Tighten the screw terminals securely.
What is the attenuation range?
The attenuator offers a range from 0 dB (full volume) to -40 dB (minimum volume) in 10 steps.
Is the attenuator stereo or mono?
The AT100-PARM is a mono attenuator. For stereo applications, use two units or a stereo model.
Does the attenuator require a power source?
No, it is a passive device that does not need any external power supply. It uses a resistive network to reduce signal strength.
What type of wire should I use?
Use standard speaker wire (16 AWG or thicker) for best results. The screw terminals accept up to 12 AWG wire.
Can I adjust the volume while music is playing?
Yes, the rotary knob can be adjusted at any time. However, to avoid a sudden spike in volume, turn it slowly.
How do I clean and maintain the attenuator?
Wipe the faceplate with a dry, soft cloth. Do not use any solvents or abrasive cleaners. Periodically check the wire connections to ensure they are tight.
