  • Four Channel IP Network Audio Adapter
  • T-6704



The T-6704 is a compact four zone IP/TCP network audio system solution, which is integrated four separated network audio adapters into a chassis, each network audio adapter is of different IP address from others, thus different program could be designated to different zones at the same time.

It is used to transmit program from internet to four amplifiers and 4 zone loudspeakers. So the normal connection way as below: LAN Control port by RJ45 connector to LAN switch, Local four zone aux inputs from four separate source players, aux output to the zone amplifier line input, the zone amplifier 100V speaker output to each Channel input (Com & Input Hot end), the four channel outputs are designed to connect with three wired volume control then to loudspeakers (Com, EMC and Hot). The serial port is used only for write or change the IP address. The redundancy RJ45 port is only connected for LAN switch backup use or two units cascaded use.

The IP network audio adapter is of 19 rack mount design, so it cloud be installed in any where of the non-dedicated network. It is high economy to matching with ITC series analog or Class-D two ranges four channel power amplifier for a four zone 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.
