    Installation and Power Unpacking and Installing the Console The AIR 1 console with its power supply, connecting cable, and techni- cal manual is shipped in one packing box. The console can be unpacked by one person by grasping the console at the both sides, and lifting it up-...

  • Page 7: Power Supply

    Energizing Assuming the AIR 1 console mainframe is properly placed, and its power supply correctly connected to the console, you may now energize the power supply adapter by plugging it into the AC mains. The console’s switches will assume factory default settings.

    (like Belden 9451), just as if you were connecting a balanced source. At the unbalanced source machine’s output, connect the black wire (LO) to the shield. ANALOG OUTPUTS – The AIR 1 console’s PGM 1 and PGM 2 line level analog outputs are electronically balanced, low impedance, outputs, expecting a minimum load of 600 ohms.

  • Page 13: Overview

    Console Features Overview The AIR 1 console consists of an input section with eight faders and associated switches, monitor and headphone section with two faders and associated switches. The basic purpose of the console is to take some of the many audio signals that are wired to the console inputs, and generate several outputs that combine these inputs in various groups and at various degrees of loudness, or signal strength.

  • Page 15: Inputs

    C O N S O L E F E A T U R E S Inputs The AIR 1 console is designed to handle 6 analog stereo (+4dBu balanced) inputs, two mono microphone (-50dBu balanced) inputs, and one external stereo line level (+4dBu balanced) input that goes directly to control room or meter.

  • Page 16: Outputs

    When SW 11 is DOWN the PGM 2 is in stereo mode. Monitor Output The AIR 1 has a MONITOR output designed to drive a stereo pair of powered speakers, or a stereo amplifier driving separate speakers, to allow the operator to listen to either PGM 1 or PGM 2, or an external signal.

  • Page 17: Split Cue, Monitor

    ON AIR LED in the center of the meterbridge is also turned on, and a closure is provided at the TALLY output to activate the external circuitry for the ON AIR indicator. page 2 – 6 AIR 1 / Mar 2012...

  • Page 18: On Air Tally

    Audio coming back from the computer via USB shows up as a stereo analog signal on the LINE 8 fader as long as there are no connections made to the LINE 8 input jacks. page 2 – 7 AIR 1 / Mar 2012...

  • Page 19: Using The Usb Port

    Air 1 USB port. Use a cable having a USB Type B connector on the Air 1 end and a connector on the other end that will mate with the computer’s USB port; this will typically be a USB Type A connector.

  • Page 20: General Considerations

    PGM 1 and PGM 2 as the source (see page 2-7). • The audio coming back into the Air 1 on the USB port is available at the LINE 8 fader as long as nothing is plugged into the LINE 8 input jacks.
