Extron electronic SW AV manual All switcher models

Audio follow — If the switcher is also a video model, audio can be switched with the corresponding video input. Audio follow switching can be done via front panel control or under RS-232 remote control.

Audio breakaway — If the switcher is also a video model, audio can be broken away from its corresponding video input signal. Audio breakaway switching can be done via front panel control or under RS-232 remote control.

Executive mode (front panel security lockout)— All switchers that route audio have an executive mode that locks out the I/O (video/audio/video and audio) selection button, toggling between autoswitch and normal mode, and all audio gain and attenuation adjustments at the front panel. If a switcher is installed in an open area, where operation by unauthorized personnel may be a problem, the switcher can be placed in executive mode. When the front panel is locked, a special button combination is required to unlock the front panel controller before audio gain and attenuation can be adjusted locally.

When the front panel is locked out, audio gain and attenuation is still available via the RS-232 link.

All switcher models

Operational flexibility — The operator can select the input, set the audio gain and attenuation for each input, set the switch mode, and toggle executive mode on and off using:

•Front panel controller — The SW AV series front panel controller supports touch-of-a-button input selection, audio gain and attenuation control, switch mode selection, and executive mode selection.

•RS-232 control — The switcher’s RS-232 link on the RS-232 (SW 8 and SW 12 models) or Remote (SW 4 and SW 6 models) port. The RS-232 link allows remote control via a PC or control system.

°Windows-based control program — Extron’s Windows-based control program provides a versatile range of operational options with its graphical interface and drag-and-drop/point-and-click operation.

°Simple Instruction Set (SIS™) — The Simple Instruction Set program lets a host computer control the switcher with simple commands.

°Optional infrared remote control — The operator can also control the switcher using Extron’s IR 102 Universal remote control kit

(part #70-224-01) connected to the RS-232 or Remote port.

•Contact closure (4-input and 6-input models only) — The operator can remotely control the SW 4 and SW 6 switchers using a contact closure keypad connected to the Remote port. The switcher’s contact closure link on the Remote port.

Rack mount — Rack-mountable in any conventional 19" wide rack with the included rack ears.

Power supply — Includes an internal 100 VAC to 240 VAC, 50/60 Hz, 15 watts, autoswitchable power supply, which provides worldwide power compatibility.
