product model: DSP-1000 FEATURES: * Two groups stereo or two groups digital audio signal input (The simulation is RCA and XLR connector, the digital support the coaxial and optical fiber. Choose one from the three, the DSP internal support the stereo process. 5 transmitters input,6 port simulation audio signal output. * PC long-distance control by use the attached software： short distance can be control by connecting through USB connecter or RS-485 connecter. Long-distance control through RS-485 connecter. It can control maximum 250 pcs products, maximum distance 1000 meters. (It depends on the electromagnetic environment.) |
