Description
The MS-704 is a 2RU four-channel main station with programmable front panel buttons, individual channel short-circuit protection, individual channel volume control, and a regulated fail-safe power supply. The MS-704 supports up to 55 beltpacks or 10 speaker stations, or 12 headset stations.
Audio Sources and Monitoring
The MS-704 accepts five separate program audio sources: four line-level balances inputs and one assignable line-level input. The assignable program input accepts a balanced signal and is designed for monitoring external audio. The four balanced program inputs can be used to create individual program feeds on the intercom channels. The MS-704 can monitor intercom activity on one or all four channels with individual volume level controls. Monitoring intercom activity is possible through a headset or the internal high-sensitivity loudspeaker.
Talk Selection
The MS-704 has mic pre-amps with limiters and speech-shaping circuits. 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.
Announce Output
For paging, the MS-704 provides a balanced, line-level output signal to a ?-inch TRS connector on the rear panel. The front panel Announce button activates the output and th Announce relay. The relay circuit, on a separate ?-inch TRS connector, is typically used to mute monitors.
Call Signaling
The MS-704 has individual Call buttons with visual call signaling for each channel on the partyline. The visual signal will flash brightly and will emit an audible signal if the remote station operator holds the Call button for more than 2 seconds. The call signaling feature can be programmed to the Talk buttons.
描述
MS-704是一個2RU四通道主站，具有可編程前面板按鈕、獨立通道短路保護、獨立通道音量控制和穩(wěn)壓故障安全電源。 MS-704支持多達55個腰包或10個揚聲器站，或12個耳機站。
音頻源和監(jiān)控
MS-704 接受五個獨立的節(jié)目音頻源：四個線路電平平衡輸入和一個可分配的線路電平輸入?？煞峙涞某绦蜉斎虢邮芷胶庑盘?，專為監(jiān)控外部音頻而設計。四個平衡的節(jié)目輸入可用于在對講頻道上創(chuàng)建單獨的節(jié)目饋送。 MS-704 可以通過單獨的音量控制監(jiān)控一個或所有四個通道上的對講活動。可以通過耳機或內部高靈敏度揚聲器監(jiān)控對講活動。
談話選擇
MS-704 具有帶限制器和語音整形電路的麥克風前置放大器。每個通道都有一個單獨的電子瞬時/鎖定通話按鈕。帶燈的雙動通話按鈕在鎖定時會發(fā)出微弱的 LED 燈：待機時為藍色，鎖定時為琥珀色?？梢越面i定功能。這些通道可以單獨或同時訪問，而無需將它們捆綁在一起。選擇器開關在耳機或麥克風之間切換。通話按鈕也可以通過腳踏開關進行控制。
宣布輸出
對于尋呼，MS-704為后面板上的1/4英寸TRS連接器提供平衡的線路電平輸出信號。前面板Announce按鈕激活輸出和Announce繼電器。繼電器電路位于單獨的?英寸TRS連接器上，通常用于使監(jiān)視器靜音。
呼叫信令
MS-704有單獨的呼叫按鈕，partyline上的每個通道提供可視呼叫信號。如果遠程站操作員按住呼叫按鈕超過2秒，視覺信號將明亮閃爍并發(fā)出聲音信號。呼叫信號功能可以編程到通話按鈕。
