How To Switch Between Studios or Turn On / Off Automation


Active Studio - Only one studio can be active at a time.  The active studio is the studio whose audio (from the PGM-1 bus) is fed to the transmitter and web stream.

Automation - When automation is active, neither studio is active.  Both studios can be used for other purposes such as training or preproduction.  No audio from either studio will be sent to the transmitter or web stream.

Automation audio can be supplied from the ENCO machine in either studio. The computer that is supplying audio will show a playback deck (DECK4) running by itself. Do not interfere with the operation of this deck. All other ENCO features can be used for local production without affecting automation.

Stack Lights – The colored stack lights indicate important things at a glance. For this document remember that a green light indicates which studio is active. A blue light indicates that automation is engaged and audio is present.

Monitors - Use the Axia monitor controls on the console to select what audio you are listening to.  Choices include:

EXT1 : "To/Air Web" - This is the default monitor source.  It will monitor the audio that is actually going to the transmitter and web regardless of whether that audio is coming from Studio1, Studio2, Production, or automation.

EXT2 : "91.7 FM" - This is the audio output of an FM receiver tuned to our frequency.  It monitors our actual on air signal.  Note that this is (obviously) post delay.

PGM1 : You would normally use this source if you are doing some local audio production in a studio which is not currently on air.

PGM2, PGM3, PGM4, AUX A, AUX B, AUX C, AUX D : More busses that you can use for whatever creative purpose you have in mind.  Never let it be said that we don't provide you with a lot of busses.


Switching Studios:

We use an ARM / TAKE method of switching studios.  This is a standard interlock technique in broadcast that guarantees that both the studio that is ceeding control and the studio that is taking control are prepared for the transfer.

Locate the backlit LCD buttons for the subsequent procedures.



From the currently active studio (the one giving control):

Press the GREEN "GIVE STUDIO" Button.

The studio is now armed for the other studio to take.

You may press the button a second time to cancel and disarm the transfer.


From the studio taking control:

When the transfer is armed, the "TAKE STUDIO" button will illuminate. 

Pressing the "TAKE STUDIO" button will transfer control to the waiting studio.

To ensure a smooth transition wait for a suitable break in the audio.

The transfer does not crossfade.  There is a short fade down, the transfer, and then a short fade up.  The transition takes about 1 second.

Turning Automation On:

Press the GREEN “GIVE STUDIO” Button.

Two buttons will begin to flash which are marked “S1 AUTO” and “S2 AUTO”.

Press either button to start automation. The “S1” and “S2” labels just indicate which ENCO computer will run the automation program. It does not normally matter which one is selected. 

Automation takes a few seconds to complete all of the necessary start up checks.


Turning Automation Off:

You can return from automation to live broadcasting from either studio.

From whichever studio you wish to broadcast from you will see an LCD button marked “RETURN TO S1” if you are in Studio 1 or “RETURN TO S2” if you are in Studio 2.

When you press the button, automation will stop cold and control will immediately transfer to the studio you are in. There is no fade out. Therefore it is important to wait for a suitable break in the audio.



If something unexpected happens, press the “KNOWN GOOD” button from whichever studio is experiencing the problem. Among other things, this button causes the system to double check all the audio assignments for that studio.

Consoles can lose their state if they are powered down or rebooted during operations. Pressing the “KNOWN GOOD” button will restore their state.

If the ENCO automation playback deck is accidentally stopped, it can be resumed by pressing “CTRL + PLAY”. Using this key sequence will cause it to start from where it left off, rather than from the top of the playlist.

Refer to the studio technical binders if trouble develops.
