CLEAR-COM对讲系统RM-702介绍
Encore™ is a 2-wire analog partyline system with intuitive plug-and-paly design and superior “Clear-Com Sound”audio clarity.
Description
The RM-702 is a 1RU two-channel remote station with programmable front panel buttons and individual channel volume control. The RM-702 is powered directly from the intercom line and requires no external AC power. Unlike the MS-702, the RM-702 has no power supply, circuit breaker or linking function.
Monitoring System
The RM-702 can monitor intercom activity on one or both channels with individual volume level controls. Monitoring intercom activity is possible through a headset or the internal high sensitivity loudspeaker.
Talk Selection
The RM-702 has mic pre-amps with limiters. An individual electronic momentary/ latching Talk button is available for each channel. Illuminated dual-action Talk buttons light an LED dimly when latched: blue-color while in standby, amber-color when latched. The latching feature can be disabled. The channels can be accessed separately or simultaneously without tying them together. A selector switch toggles between the headset or microphone. The Talk buttons can also be controlled with a footswitch.
Call Signaling
The RM-702 features individual call buttons and visual call signaling to attract the attention of operators who have removed their headsets or turned o their speakers. The visual signal flashes the illuminated Talk button when a call is received. The call signaling feature can be programmed to the Talk buttons.
Program Interrupt (IFB)
The RM-702 accepts either a balanced or unbalanced line-level audio input through the DB-15 connector on the rear panel. The program can be monitored at the station or fed into another channel where it can also be set up for IFB/Program Interrupt from this or any other station.
描述
RM-702 是一个 1RU 的两通道远程站，带有可编程的前面板按钮和单独的通道音量控制。 RM-702 直接由对讲线路供电，无需外部交流电源。与 MS-702 不同，RM-702 没有电源、断路器或链接功能。
监视系统
RM-702 可以通过单独的音量控制监控一个或两个通道上的对讲活动。可以通过耳机或内部高灵敏度扬声器监控对讲机活动。
谈话选择
RM-702 具有带限制器的麦克风前置放大器。每个通道都有一个单独的电子瞬时/锁定通话按钮。带灯的双动通话按钮在锁定时会发出微弱的 LED 灯：待机时为蓝色，锁定时为琥珀色。可以禁用锁定功能。这些通道可以单独或同时访问，而无需将它们捆绑在一起。选择器开关在耳机或麦克风之间切换。通话按钮也可以通过脚踏开关进行控制。
呼叫信令
RM-702 具有单独的呼叫按钮和可视呼叫信号，以吸引已摘下耳机或关闭扬声器的操作员的注意力。接到电话时，可视信号会闪烁点亮的通话按钮。呼叫信号功能可以编程到通话按钮。
程序中断 (IFB)
RM-702 通过后面板上的 DB-15 连接器接受平衡或非平衡线路电平音频输入。节目可以在该站监视或馈送到另一个通道，也可以设置为来自该站或任何其他站的 IFB/程序中断。
