Once in common use in radio, the passive attenuator is used less frequently today because of active circuitry and bridging impedances instead of matched impedances. The basic attenuator is a T pad, ...

A single-channel audio attenuator package maintains input-signal fidelity as it attenuates the signal level in 1-dB selectable steps over 0 to -62 dB. National Semiconductor's LM1971, with 3-dB ...

Low-profile audio attenuators provide 47 positions with selectable end-stops from 1 to 6 channels, boast high-end volume control, superb sonic performance and precise switch feel. The A47 audio ...

That Corp recently announced the That5171 SPI (serial-peripheral-interface)-controlled digital attenuator. The fully differential device serves as part of a differential-audio-signal path. You can set ...

In low-end audio systems, digital potentiometers can be used as audio attenuators or amplifiers (Fig. 1). Unfortunately, a large change in volume at an arbitrary time can cause an abrupt discontinuity ...

For the money, giving emergency attenuation right where you need it, it'd be well worth having a few of these handy. Best guitar cables 2025: Leads and patch cables for all budgets Best earplugs for ...
