•Program audio switcher — A four input, one output stereo audio switcher allows the audio input of any video group to be selected for the program audio output, with volume and mute control. The MPS 409 features balanced/unbalanced program audio output on a 5-pole captive screw connector.

•Microphone/line input — One 3.5 mm captive screw connector is used for a balanced/unbalanced Mic or Line level input. The input has an adjustment range of -66 dB to +12 dB. The microphone input includes a Mute button for "talk‑over", with adjustable threshold and volume control.

•Front panel security lockout (Executive mode) — Prevents unauthorized use in non-secure environments. Locks out all front panel functions except input selection and program volume control to prevent unauthorized changes.

•RS-232 remote control — A rear panel RS-232 port enables control via a control system. Extron Electronics Simple Instruction Set™ (SIS™) allows for quick and easy programming.

•Rack-mountable— The 1U high, full rack width, metal enclosure is rack‑mountable, with supplied rack mounting brackets.

•Multiple switcher modes — Multiple switcher modes provide flexible signal routing capabilities to address the varying system switching environments. Users can choose among four switcher modes: Single, Separate, Single-combine, and Separate‑combine.

оо Single switcher mode — Allows one-touch switching. When one of the nine inputs is selected, video and associated audio input signals are routed to the outputs of its group; the selected audio is also routed to the program audio output. In this mode, outputs of the other groups are muted.

оо Separate switcher mode — Allows independent switching of any given group. This effectively segregates switching operations so that the MPS 409 becomes four separate video switchers. While operating in separate switcher mode the program audio can be output from any group, while cueing up for another group, without interruption.

оо Combine switcher mode – Allows up to five HDMI and DVI source devices to be routed to a single HDMI-enabled digital display. Audio from the corresponding digital input, connected through the 3.5 mm stereo jack, is routed to the local and program audio outputs. This mode can be used when the switcher is in Separate or Single switcher mode.

•Front-panel Mic and Program Audio output volume controls — To streamline audio setup, the MPS 409 features front-panel Mic and program audio output volume controls which allow for easy and separate adjustment of Mic and program audio volumes. This eliminates the need for audio preamplifiers in many system designs.

•Audio input gain and attenuation — Allows users to set the level of audio gain and attenuation for each input channel so that there are no noticeable volume differences when switching between sources.

•Mic talk over — The talk over feature automatically reduces program audio when it detects a microphone signal. This eliminates the need for a separate stand-alone audio ducking processor. The talk over level is adjustable via the RS-232 control.

•HDMI 1.3 compatible — Supports HDMI 1.3 specification features, including data rates up to 6.75 Gbps, deep color, auto-lip sync, and HD lossless audio formats.

•Audio breakaway — Provides the capability to break an audio signal away from its corresponding video signal and route to the program audio output, allowing the audio channels to be operated as a separate switcher.
