Audio gain and attenuation | Extron electronic 1616 HV, HVA instruction

Operational flexibility — Operations such as input/output selection, setting of presets, and adjustment of audio levels can be performed on the front panel or over the RS-232/RS-422 link. The RS-232/RS-422 link allows remote control via a PC, RS-232 capable PDA, or control system.

•QuickSwitch Front Panel Controller (QS-FPC™) — The CrossPoint Plus series QS-FPC feature supports touch-of-a-button input and output selection, preset creation and selection, and audio gain and attenuation control.

•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. The Windows-based control program also has an emulation mode that lets you create a switcher configuration file at the home office and then download it for use by the switcher on site.

•Simple Instruction Set (SIS™) — The remote control protocol uses Extron’s SIS for easy programming and operation.

Audio gain/attenuation — Users can set the input level of audio gain or attenuation (-15dB to +9dB) via the RS-232/RS-422 link or from the front panel. Individual input audio levels can be adjusted so there are no noticeable volume differences between sources (figure 1-3).
