Compact matrix switch

AUTHOR: Inavate

Hall Research Technologies said its 16x16 VGA/HDTV is the most compact matrix switch it has released so far. The Model VSM-I-AP-16-16 is controlled via the front panel, serial RS-232 and IP ports.

All AV and control connections are on the rear of the rack-mountable unit. Standard HD15 video connectors directly tie to PCs or LCD's and can also be used with YPbPr video signals.

The matrix is compatible with PC video to 1920x1600 or analogue SD/HDTV Component Video from 480i to 1080p.

Stereo audio inputs may be routed to follow the video or switched independently. Balanced stereo outputs on screw terminals are provided that can be set to either standard line level of –10 dBV or professional level of +4 dBu.

Each audio input features a user programmable gain or attenuation stage with a range of +6 dB to –24 dB. This allows normalisation of volume levels among all the sources so when outputs are switched between inputs with different audio levels, the signal remains at a constant volume. In addition, during the audio gain adjustment, the front panel LED’s act as a precision VU bar level meter.

Built-in battery-backed clock/calendar and scheduling feature enables the matrix to recall various preset patterns at specified times throughout the day.
