1. Description of product
1.1 About MAG68 series networked playing power amplifier

MAG68 series networked playing power amplifier is a kind of fully networking digital analog-digital
signal processor supporting 100/10Mbps self-adaptation TCP/IP network transmission protocol; with
the design of double network backup, it is allowed to access to any switch simultaneously. Furthermore,
this machine has the functions of network line fault detection and automatic selection in order to
improve the reliability.

The remote audio data stream is able to output the audio signal with this machine, and the host is subject
to the intelligent control; in this machine, there is a built-in MP3 player with USB interface and SDC
card port, so as to play MP3 program on this machine without playing the internet audio signal; there is
a channel of auxiliary audio input interface used for connection of other audio source equipments (e.g.
DVD machine); there is a channel of auxiliary audio output interface used for connection of other power
amplifiers and extension of the power. There is also a channel of microphone interface used for local
paging and so on.
1.2 Function features:

This machine is made of high-grade aluminum-alloy drawn panel.

It is allowed to suspend the machine any place accessible to the network. The network transmission
protocol developed independently by DSPPA network team to achieve the dynamic audio data
transmission. With the double network interface redundancy design, it is possible to work crossing the
network segments.

There is the built-in high-efficiency digital power amplifier with 100V constant voltage output, resulting
in the efficiency higher than 90%.

There are the MP3 player, USB port and SD port, which are used to play the local programs.

The maximum output power of the amplifier shall be 60W, 120W, 250W, 350W, and 650W respectively.

The eye-catching design of the digital display screen is able to display not only the time of the clock, but
also the time of the playing progress.

With the time frame synchronization mechanism, it achieves the real-time synchronization of the clock
of the machine and the clock of the networked host.

This is the built-in infrared receiving module under the control of the infrared remote controller, so it is
easy for use.

The panel integrates five status indicator lamps to show the working conditions clearly.

On the panel, there are eight shortcut buttons, facilitating the daily use of the local user.

It has the built-in offline local timing-point playing function, so as to back up and store the timing
programs into the SD card, and back up the timing-point programs automatically.

Outside the machine, there is a channel of AUX line input, a channel of microphone input, and a
channel of AUX line output, in order to facilitate the expansion of the other local sound source
broadcasting and expansion of local power.

It has the priority management function at the level 8 or above; the local microphone is equipped with
