Product Code TV1T-DA-124
Manufacturer TV One

Request more information or contact us now for purchasing information.


1T-DA-124 Dual Audio DA is two separate Distribution Amplifiers in a single case. A 1x4 Analog Stereo DA via 3.5mm Mini-Stereo connectors and a 1x4 S/PDIF DA via RCA coaxial connectors. Inputs between the two amplifiers do not cross over and there is no Analog-Digital conversion between the two. Audio Bandwidth is 20Hz to 20KHz and the signal processing system ensures a low signal to noise ratio plus flat equalization curves throughout the bandpass spectrum. Impedance is 20KΩ for Analog Stereo signals and 75Ω for S/PDIF signals. Analog Signal Levels are Unity Gain. S/PDIF levels are unity and may be from 0.5 to 1.0 Vp-p.

The DAs can be cascaded for expanded functionality. An optional Rack Mounting kit provides for mounting either one or two units.
