Coaxial cable attenuates high frequencies more than low frequencies. The TSEQ-2150 creates an attenuation loss equal and opposite to cable loss. This problem is most severe when cascading amplifiers one after the other. The signal differences are amplified to a point where the higher frequency signals are so small compared to the low frequency signals that they can no longer be received. The TSEQ-2150 provides a balanced signal level by compensating for the high frequency attenuation and allowing all signal levels on all channels to be of equal amplitude at distant locations. Therefore, the picture quality on higher channels will be maintained.
