概要

本设备是 12 路输入 8 路总线 8 输出、3U 大小的支架固定数字音频混合器。安装了反馈抑制功能、自动调

音功能等声音系统必要的信号处理功能。所有参数均可通过本体设备进行设定*。可将设定状态作为预设记

录保存在设备内部的记录中，并通过前键操作将其打开。

* 也可使用专用软件，通过计算机进行设定。

请从「http;//toa-products.com/」网站下载专用软件。

特点

 通过简单操作即可抑制啸叫。

 装有自动调音功能（Ducker 功能*1、NOM 衰减功能*2），可自动调整输入信号音量。

 采用数码信号处理技术，可设定高精度的音响参数。

 通过使用前面板的液晶显示部位、设定键、设定旋钮，所有设定均可在主机上进行。并且如使用专用

软件，也可通过计算机进行设定。

 输入输出部分采用了模块，可实现从 2 输入 4 输出至 12 输入 8 输出的输入输出构成。

 内部设有 16 个预设记录。可从主机及外部设备中恢复预设记录。

 使用 RS-232 端口，可从外部控制设备进行控制。

 本设备带有保护功能，可防止错误操作前面板的按键或旋钮。

 可用 AMX 或 Crestron 等控制器进行控制。

 使用可选的遥控模块 D-981 时，可很方便地遥控进行音量调节或提取记录等。

*1

是一种根据输入信号电平，自动调整各输入通道增益的自动混音功能。（ P. 32 ）

*2

是一种根据开启状态的话筒数，自动调整开启话筒的输入通道增益的功能。（ P. 34 ）

※ AMX 是 AMX Corporation 的商标。

※ Crestron 是 Crestron Electronics，Inc.的商标。

使用注意事项

 请在温度为+5℃～+40℃，湿度在 90%以下（不结露）的场所使用本设备。

 本设备是精密设备，请避免强烈撞击或震动。否则会导致设备故障。
