BE-255 is a double amplified, adjustable audio-level attenuator circuit by Philmore. It is designed to reduce the volume or gain of an audio signal while preserving the audio waveform designed. It has a maximum attenuation of 20db, is fully adjustable and is designed to drain off low frequency input signals to reduce power consumption. The BE-255 can be used in conjunction with pre-amplifiers, speaker or mixer systems, or audio equipment.
