Damping Resistor Unit [ET-1372]

We have implemented 48 circuits of resistance attenuators.

■□■Features■□■ ■This is a device that implements 48 circuits of resistive attenuators to ensure the matching of voice levels between four-wire telephone lines (4WS, 4WR) during relay connections between terminal stations. ■The attenuation can be set to a range of 0 to 15.5 dB (in 0.5 dB steps) by combining attenuation values of 0.5, 1, 2, 4, and 8 dB.
