The DA103-217 has a powerful equalization circuitry and can recover degraded VGA signal as far as 250 ft away when standard VGA cable is used. When connected at the end of a cable, the DA103-217 can significantly improve image contrast and sharpness. When VGA signal travels through coaxial cable, the signal gets degraded due to the capacitance and resistance of the cable. With every foot of cable, the quality of the signal decreases slightly.

The DA103-217 has adjustable circuitry to improve signal quality and compensate for the losses in the coaxial cables. This is done using (EQ) equalization control for image sharpness and (GAIN) gain control for image contrast. With a wide range of adjustment, the DA103-217 can restore VGA signals that have been degraded by 30% due to cable length or multiple cable interconnections using gender benders.

In addition to video quality improvement, the DA103-217 has a built in AGC (Automatic Gain Control) for horizontal and vertical sync signals that automatically adjusts to any sync signal from 1volt peak to peak to 5 volt peak to peak amplitude. With this feature, it is virtually assured that DA103-217 will process any type of sync signal coming in and will convert it to a proper format for a display or a projector.

Sync adjustment control allows selecting the most stable portion of the sync signal for recovery. When the sync signal travels more than 25ft, it gets distorted due to improper sync termination and signal reflections. Most of the sync signals have an output impedance of 10-20 ohms, but the cable used for sync signals is 75 or 300 ohms. This cable impedance mismatch creates reflections and sync distortions that results in unstable image, jitter, or loss of image completely.
