Audio features

Captive screw audio connector (A) models — These switchers input and output balanced or unbalanced stereo audio signals, on 3.5 mm, 5-pole captive screw terminals.

RCA audio connector (A RCA) models — These switchers input and output unbalanced stereo audio signals on left and right RCA connectors.

Audio input gain/attenuation — You can set the level of audio gain or attenuation (+10 dB to –18 dB) via the RS-232 port or from the front panel. Individual input audio levels can be adjusted so there are no noticeable volume differences between sources and for the best headroom and signal-to-noise ratio. This function also eliminates the need for separate preamps or attenuators when used with professional (higher line level) and consumer (lower line level) audio equipment.

Audio output level switch — The audio level of each output can be set to either –10 dBV (consumer level) or +4 dBu (pro level) via RS-232 control only.

Audio follow — In audio/video switchers, audio can be switched with the corresponding video input. Audio follow switching can be done via front panel control, optional IR 501 control, or the RS-232 port.

Audio breakaway — In audio/video switchers, audio can be broken away from its corresponding video input signal. Audio breakaway switching can be done via front panel control, optional IR 501 control, or the RS-232 port.

Common features

Switching flexibility — Provides individually buffered, independent matrix switched outputs with audio follow and audio breakaway for audio versions.

•Any input to any or all outputs

•Quick multiple tie — Multiple inputs can be switched to multiple outputs simultaneously. This allows all displays (outputs) to change from source to source at the same time.

Operational flexibility — Operations such as input/output selection and setting of presets can be performed on the front panel, via the RS-232 port, or using the optional IR 501 small matrix universal remote control. The RS-232 port allows remote control via a PC or control system.

•Front panel controller — The MAV series front panel controller feature supports touch-of-a-button input and output selection, preset creation and selection, and audio gain and attenuation control.

•RS-232 control — The switcher’s RS-232 port allows remote control via a PC or control system using Extron’s Simple Instruction Set (SIS™) or the included Windows®-based control program.

•Optional IR remote control — The MAV switchers are remote controllable, using the optional small matrix IR remote control.

The switcher’s IR receiver is disabled by default and must be enabled to use the IR remote control. See the IR receiver enable SIS command in chapter 4, “Remote Operation” to enable the IR receiver.

Upgradeable firmware — The firmware that controls the switcher’s operation can be upgraded in the field via the RS-232 port, without taking the switcher out of service. Firmware upgrades are available for download on the Extron Web site, www.extron.com, and they can be installed using the Windows-based control program.
