Product Details
🇺🇸 MADE IN THE USA 🇺🇸
Harrison Labs Custom Cylindrical XLR Attenuator Passive Signal Reducer (3dB, 6dB, 12dB)
Sold individually as true balanced mono units, with two required for a stereo setup (one for the Left channel, one for the Right channel). Fine-tune your audio gain structure and eliminate signal clipping with the Harrison Labs Cylindrical XLR Attenuator. Available in 3dB, 6dB, and 12dB configurations, these professional passive XLR line-level reducers provide a precise way to match output levels between your source and amplifier while maintaining a fully balanced signal path. By acting as a high-quality signal attenuator, they help lower “hot” signals to prevent distortion and allow for a wider, more usable range on your gain structure for a cleaner, more balanced audio experience. Each unit is custom manufactured using top-tier, heavy-duty Switchcraft connectors and housings for maximum durability, pristine shielding, and exceptional contact reliability, engineered with a Female Input and Male Output for standard inline placement along your signal chain.
Choosing the Right Attenuation Value
For peak system performance, selecting the correct reduction level is essential to maximizing your signal-to-noise ratio. If you are undecided between two attenuation values (e.g., 6dB vs. 12dB), the professional recommendation is to err on the side of the higher value.
Selecting the higher attenuation value (more reduction) provides a larger safety margin against input clipping and amplifier saturation. This ensures your equipment operates within its “sweet spot,” resulting in a more refined output, reduced floor noise, and superior protection for your sensitive audio components.
Attenuators can be inserted in series to produce more attenuation. For example two 3 db versions stacked will result in 6 db. When a 6 db is added to a 12 db the result is 18db.
The minimum load impedance that will result in further attenuation is 20K ohms. However, for most applications, the exact attenuation is not that important.
Attenuators may be needed when using 2 high pass or 2 low pass FMODs™ in series to increase slope or modify crossover frequencies.
Feedback on Custom Cylindrical Passive Inline Attenuators
Dear Sir/madam
I just wanted to let you know that I have received the attenuators and have now had a chance to properly try them in my system.
I am very pleased with the results. The -12 dB attenuation turned out to be an excellent match for my setup, giving me exactly the reduction in signal level I was looking for. What surprised me even more was the overall improvement in the sound presentation. The soundstage feels more open and balanced, with a very natural and clean presentation.
Overall, I am extremely happy with the result.
Thank you very much for the fast delivery and, most importantly, for making such an excellent product. I really appreciate it.
God bless you . 🙏
Best regards,
Emilio C.
