00:00:04:15 - 00:00:36:10 Unknown Operating the mixing console. This video will provide you with a complete overview of the Studer On- Air 1500 radio console. Table of contents. Console Overview; Recalling Snapshots; Channel Strip Operation; Studio Monitoring, Talkback and Communication; and Using the On-board Counter. Console Overview: The On-Air 1500 is the heart of four of the five studios in the Allan Slaight Radio Institute. 00:00:36:12 - 00:00:57:17 Unknown Let's take a look at the different sections of the console and what each one does. On the left, we have 12 channel strips to mix up to 12 mono or stereo inputs. Above that is our counter and recorder, allowing us to keep track of time and make recordings of our work. Beside that, in the top right corner are our meters, showing our overall output levels. Below the meters, 00:00:57:18 - 00:01:22:01 Unknown are our monitor controls allowing us to make adjustments to what we hear in the control room and adjoining interview room, or announce booth. Below that are our talkback controls, which help facilitate communication between the studio and booth. Lastly, in the bottom right corner, we have our snapshot selectors, which enable different users to select different layouts and presets for the console. Recalling snapshots: 00:01:22:03 - 00:01:46:17 Unknown Let's start with the snapshot selector. Each snapshot saved to the OnAir 1500 can contain a different configuration of input and output routing. In a professional radio station, this type of quick recall is useful when one studio serves multiple programs with different requirements. Since different students will be using the control rooms for different applications, it's important that before doing anything, we restore the board to a standardized setting. 00:01:46:18 - 00:02:09:18 Unknown SNAP 1 is our basic template for production work in the Allan Slaight Radio Institute. To load SNAP 1, press and hold the LOAD SNAP button while also pressing the SNAP 1 button. Release both buttons and the SNAP 1 button should now be illuminated, meaning the snapshot has been loaded successfully. Channel Strip Operation: Now let's look at our channel strips. 00:02:09:19 - 00:02:30:23 Unknown Each of the 12 channel strips allows the user control of a mono or stereo input signal. On the left you'll find line level inputs such as computers, a mini jack input, and a phone hybrid. On the right, you'll find our control room and booth microphone inputs. Each channel strip has an ON button below the fader. To send a signal to the Master program bus, 00:02:31:00 - 00:02:48:07 Unknown we'll need to ensure this button is illuminated. Next, we'll want to bring up the fader on the channel strip to a position known as unity, marked with a zero beside the fader. Once the fader is at unity, turn your attention to the rotary encoder at the top of the channel strip, which can be used to control multiple parameters of the channel. 00:02:48:07 - 00:03:21:11 Unknown By default, this should be set to control the channel's input gain. You can confirm this setting by looking to the right of the channel strips at the rotary encoder assigned section, and ensuring GAIN/CAL is selected. Setting a source’s input gain to an appropriate level is essential whenever introducing a new source. Watching the program meter in the top right corner of the console and with the source audio playing, or with talent speaking into their microphone, adjust the rotary encoder so that the program's output level is averaging around -20 dbfs, with peaks around -10 dbfs. 00:03:21:12 - 00:03:41:03 Unknown This process should be repeated for each signal included in your mix, and repeated any time a new person is using one of the microphones. You'll notice that when a control room microphone’s, channel strip is turned on and the fader is raised, the control room speakers automatically shut off. This is to protect from signal feeding back into the microphone. 00:03:41:05 - 00:04:10:21 Unknown If using a control room microphone input, headphones must be worn in the control room. If we want to preview an input before sending to our Master Program bus, we can use the PFL button at the bottom of each channel strip. This stands for Pre-Fade Listen and is sometimes referred to as a solo button. When engaged, the input source will play through the OnAir 1500’s built in PFL speaker, but will not go to the master program bus -- provided that the ON button is not selected for that channel. 00:04:10:23 - 00:04:32:07 Unknown Studio monitoring: Let's turn our attention to the monitor section. Here we can select which of the available output busses we wish to monitor and adjust the volume of our loudspeakers, headphones, and PFL speaker in the control room as well as the level of the booth headphones. In the top right corner of our monitoring section is the CR/ST button. 00:04:32:10 - 00:04:57:06 Unknown This allows us to toggle between controlling levels in our control room and our booth. When the button is not illuminated, our adjustments affect monitor controls in the control room. We'll want to select PGM or program in our monitor section to ensure what we're hearing is the Master Program bus output. Our DIM and CUT buttons allow us to temporarily attenuate the overall output level to our loudspeakers, or mute the signal entirely. 00:04:57:11 - 00:05:33:20 Unknown We can control the volume of our control room loudspeakers using the LSP VOL rotary encoder. This will only affect the volume of what you are hearing, not the levels that are being broadcast. The HP VOL rotary encoder adjusts the volume level sent to the board operators headphones in the control room, but this level can be adjusted further at the physical headphone output device. To adjust the levels sent to the control room guests’ headphone device, press and hold the GUEST HP button while adjusting the HP VOL encoder. To adjust the level of our built in PFL speaker hold SP and adjust the HP VOL rotary encoder. 00:05:33:21 - 00:06:03:21 Unknown Alternately, if you'd rather PFL your sounds through the main studio loudspeakers, enable PFL TO MON. When a channel strip has PFL engaged, the signal will interrupt the master program bus’ playback, but will not impact the actual output signal. Talkback and communication: In order to communicate between the control room and booth, we use a system called talkback. This allows both rooms to hear each other without including the signal in the master program bus. To talk back to the booth, 00:06:03:23 - 00:06:33:06 Unknown hold the TB ST button and speak into CR MIC 1. This is the designated talkback microphone in the control room. Alternatively, we can use the TB button located on the channel strip you would like to speak to. To communicate with the booth., we can press TB on any of the IR MIC channel strips. Note that enabling the TB function will temporarily mute the board operator's microphone from the main program bus, as well as automatically dimming the control room loudspeakers. 00:06:33:12 - 00:06:58:05 Unknown Be sure to disable Talkback when not in use. Talkback received from the booth will be audible through the built in PFL speaker. To also hear it through the headphone outputs in the control room, ensure HP SPLIT is engaged in the monitor section. Using the On-board Counter: Lastly, let's look at the counter. While each studio and control room contains a network synced clock, 00:06:58:07 - 00:07:22:02 Unknown the counter enables users to time shows in a number of fashions. Beneath the counter display are four buttons, allowing the counter to function in different ways. If REC INFO is selected, it will count down the remaining record time available on your USB memory stick. If CLOCK is selected, the counter will display the time of day. If FADER is selected, the counter will act like a stopwatch, 00:07:22:04 - 00:07:42:17 Unknown starting from the time the last used fader was activated, stopping when the fader is lowered or when the channel is taken off air. This feature can be used in situations such as timed live talk segments. If MAN is selected, the counter functions like a stopwatch. If the COUNT DOWN button is illuminated, the counter will count down from a manually programed time. 00:07:42:20 - 00:07:57:17 Unknown After selecting MAN and COUNT DOWN, use the left and right arrow buttons to adjust the time you would like to use. When ready to count up or down, press START. Press STOP once to pause the counter or twice to reset it.
