Say Goodbye to Echo and Distortion

Are you tired of dealing with echo and distorted sound on your phone line? Our 1Db 66 Block Attenuator is here to help. Designed to reduce high audio levels that can lead to Touch Tone (DTMF) recognition problems, echo, and distorted sound, this attenuator is a must-have for anyone looking to improve their phone line quality.

Fixed Value Attenuation

Our 66 Block Fixed Value Attenuators come in 1, 2, 3, 4, 6, and 8 dB values, making them versatile and suitable for a range of applications. They are designed to be used on a split 66M block (66M1-50) and connect in-series between the telephone line or analog station port on the left side of the 66 Block, and the telephone equipment on the right side of the 66 Block.

AC Audio and DC Talk Battery

It's essential to note that there are two components to a telephone line - the DC talk battery and the AC audio. While other devices like our Loop Current Regulator and Loop Current Attenuator only affect the DC voltage and loop current of the phone line, our 1Db 66 Block Attenuator is designed to reduce the AC audio on the line without causing 'Can't Hear' problems.

Loop Current and Attenuation

When attenuating the line, it's crucial to watch the loop current on your meter or Loop Current Tester to ensure you don't bring the loop current below 23ma. Inserting too much loss can create other problems on the line, such as cut-offs, answering, and dialing problems. Our 1Db 66 Block Attenuator is designed to provide just the right amount of attenuation to fix echo problems without compromising the quality of your phone line.

Warranty and Guarantee

We stand behind the quality of our 1Db 66 Block Attenuator, which is why we offer a 1-year warranty and a 30-day money-back guarantee. If you're not satisfied with the performance of our attenuator, simply return it within 30 days for a full refund.
