Description:

T-7704 is a popular model installed in control room or sub-control room, connecting with 4 power amplifiers. It is widely used for broadcasting in hall, corridor, outdoor areas etc.

Features:

* It is a 19 rack mount IP/TCP network audio adapter, with black alumina panel, strong handle, professional mechanical assembly process, high-end appearance.

*  With embedded computer technology and DSP audio processing technology.

* Build-in 4-channel network hardware audio decoding modules, it Support TCP/IP, UDP, IGMP (multicast protocol), to realize the network transfer audio signal .

* 4-channel audio outputs to connect four power amplifiers. It adopts industrial connectors and fixing screw , with higher connection reliability than conventional connectors.

* Four independent line (AUX1/AUX2/AUX3/AUX4) audio input interfaces and network background signal mixing, with independent volume adjustment.

* With 1 AUX and Mic mix inputs, independent volume adjustment, one key to open priority, prior to network audio signal. Support zone paging (max 4 zone) function under network disconnected condition,

* With 4 independent power outputs and 2 public power outputs, it is easy to cascade with other devices. It is with intelligent power management, can automatically cut off the main power output in case of no music or paging, and make the cascaded devices enter into standby status. Meanwhile, the power output can be preset to open automatically.

* With 4-channel independent three-wire alarm relay interface, to ensure alarm can be controlled by control center, no need additional 24V DC power supply. Volume control is 3-wires connected and with no limit of quantity.  

* The rear panel has 4-channel independent two-color LED indicators to display the network connection status; the front panel has 4-channel independent two-color LED indicators to display priority level, network alarm status; one power indicator to display the power status.

* Built-in dual network interface, can easily realize network port backup and cascade with other equipment, etc.

* Support 100 self-defined audio priority silence control (support multi-channel signal amplification, mixing, three-level priority control).

* Authorization operation management function, support server unified configuring and managing the user password.

* The 4-channel network hardware audio decoding modules are with independent power switch management, to easily modify the network IP decoder address.

* It Support remote hardware upgrade of the terminal, no need to upgrade at the local site, to reduce maintenance work.
