Description

The EMS-4001 adds four powered intercom channels to an MS-2001 Master Station, and it provides talk, listen and call buttons for the added channels. Up to four EMS-4001 Expansion Master Stations may be connected to the MS- 2001 to add up to 16 channels (18 channels total). The MS-2001 microphone is used to talkback to the EMS-4001 channels, and the MS-2001 speaker is typically used for listening. However, there are also separate speaker jacks on the back panel of the EMS-4001 for independent monitor speakers, if desired. There are also 4 additional program inputs on the back of the EMS-4001, one for each added channel.

The MS-2001/EMS-4001 combination can be used as a simple, multichannel intercom user station. In this configura- tion, the program inputs (and possibly the PA output of the MS-2001) are most likely not used, and the station operator has only talk, listen and call capability. It is also possible that advanced features of the MS-2001, such as Mic Kill Send, might be turned off. Alternatively, the MS-2001/EMS-4001 can be used as a master station. In this application, one or more program inputs and the PA output may be connected, and the program signals to the inter- com channels can be turned on or off from the MS-2001. Additionally, the Mic Kill Send feature can be enabled, and microphones on any channels may then be turned off from the MS-2001.

Features

Figure 1 - EMS-4001 Front and back features.

1.Intercom Talk Keys: Momentary or latching (hands-free operation possible).

2.Call Keys: used to call intercom channels and to indicate incoming calls.

3.Intercom Listen Keys: Momentary or latching operation possible.

4.Channel Power Status Indicators: The indicators are green for normal operation and change to red if there is a short circuit or overload condition on a power output line. If an indicator turns red, either disconnect the corresponding channel connector or turn off the intercom systems and locate the problem before resuming operation.

5.Universal AC Power Connector: The unit accepts any input power in the range of 100-240 VAC, 50/60 Hz.

6.Intercom Channel Connectors: These connectors provide the power and audio connections for each of the four intercom channels.

7.EXP IN and EXP OUT Connectors: The EXP IN connector receives the microphone audio signal from the MS-2001, and it sends the monaural mix of the four EMS-4001 channels to the MS-2001 speaker or headset. The EXP OUT connector connects to the EXP IN connector of an additional EMS-4001. Up to four EMS-4001 Expansion Master Stations may be daisy chained with the EXP IN and EXP OUT connectors. An EXP IN/OUT cable is supplied with each EMS-4001.

8.SPEAKERS: Usually, the listen mix of all four EMS-4001 channels is sent to the MS-2001 speaker or headset via the EXP IN connector. Alternatively, speakers may be connected to one or more of the speaker outputs of the EMS-4001.
