Descriptions
The T-6701 is a popular used model for IP/TCP network audio system solution. It is used to transmit program from internet to amplifier and loudspeakers. So the normal connection way as below: Control port by RJ45 connector to LAN switch and analog outputs to amplifiers. The IP network audio adapter is of 19 rack mount design, so it is usually installed in the control room together with high watts power amplifier for a bigger sized application. This LAN network technology also allow this amplifier could be installed in each floor or local terminal area, thus the cable wiring cost could be saved. The biggest advantages of the network audio system are: Super distance audio transmission, simultaneous maximum program task and non-dedicated network wiring.
