2 About MSD-701AMP
The MSD-701AMP is a seven-input digital presentation switcher with built-in audio power amplifier.
The seven digital and two analog inputs accept a wide variety of video formats including HDMI, DVI,
HDBaseT, Composite video, RGB, and YPbPr. Input video signals are converted to HDBaseT and HDMI
signals at up to QWXGA or 1080p. Two selected input video signals can be displayed on a single screen in
picture-in-picture or side-by-side layouts.
Up to four audio can be mixed: one of seven digital audio, one of three analog audio, one mic, and one line.
Audio is output to digital connectors, an analog connector, and two speakers. Enhanced audio features
include compressing, limiter, and seven-band equalizer for mic input and tone controls for speaker output.
The MSD-701AMP can be configured remotely from RS-232C and LAN. External devices can be controlled
via RS-232C, LAN, CEC, or contact closure by registering control commands.
Additionally, the MSD-701AMP includes button security lockout and button caps to prevent accidental or
inappropriate changes.
