The power conditioner mounted above the base station powers the intercom system.  There is a green LED indicating when the unit is on.  There are also red LED’s that illuminate if there are problems in any of the four channels.

    There are speaker stations in these areas that serve both theatres.  Part of the stage manager’s pre-show checklist should include making sure that each speaker station is switched on and the volume adjusted so they can be heard.  These speaker stations are connected to the base station on channel D, which also carries show sound to these areas.  Each base station can also page these areas using the Announce Button (see below).

    The Mic Select switch should be in the Headset position.  There currently is not a mic on the panel.  The Mic On/Off push button allows turning the mic on or off no matter which channel Talks are selected.  The mic will be turned on automatically whenever a Talk function is activated.  If one or more Talks are active you may turn the microphone off without unlatching the active Talks (see below).

    The Speaker on the base station may be turned on and off with the speaker switch.  The large Volume knob controls the volume of the intercom channels sent to the headset and the speaker of the base station.

    To listen to an intercom channel press the Listen button for the desired channel.  The green LED above the channel indicates when a listen is active.  The Listen Level control (below the Call button) for that channel is usually set to full and the listening volume is set by the Volume control to the left of the speaker.  If several channels are being listened to at the same time it might be desirable to adjust the individual Listen Levels of each channel for the proper mix.

    To talk on an intercom channel, press the desired Talk button.  Pressing and holding the button will cause the function to be active only while the button is held.  Pressing and releasing the button quickly will cause the function to latch on if it was off, or latch off if it was on.  The button will be illuminated dimly while the talk function is on.

    Pressing the All Talk button sends the mic signal to ALL channels while the button is held.

    To hear show sound in the headphones or speaker of the base station adjust the Program Level control below the Link and All Talk buttons.  Show sound for each theatre is sent to the Green/Dressing Rooms on Channel D.  The Inge Lobby also receives Show Sound on channel C.  Show sound can be added to the other intercom channels if desired, please see the UT Technical Staff.

    To send a Call signal, press the Call button for that channel.  Receiving a Call signal is indicated by a flashing Talk button.

    The Link button allows connecting channels B, C and D to channel A.  Talk and Listen buttons are non-functional on channels B, C and D when they are Linked to channel A.  The LED below the channel A Talk button indicates when all channels are linked together.  This feature is rarely, if ever, used at the UT.

    Pressing this button allows the Stage Manager to page the Green/Dressing Rooms. The Talk and Listen latches are not reset, but the microphone does not go to the intercom line when the Announce button is pressed.  The Announce microphone is the headset plugged into the base station.  Note that the Announce feature for either theatre will be heard on the speaker stations even if the speaker station is switched to the other theatre.

    Belt packs, headsets, cables and other supplies are stored in the cage by the gel room.  Intercom jacks are located in various places around the theatre.
