Switchers provide a solution for distribution and control of multiple A/V
sources to multiple A/V devices. The defining function is that
ability to control any input from any output individually, ideal for
sophisticated home A/V distribution as well as commercial applications
for bars/ restaurants and professional video
there are analog models for VGA and Component as well as digital DVI (HDCP
compliant) that can be used for DVI/HDMI equipment.

Analog Matrix Switchers are available for manufacturers of quality
products like Key
Authority. These devices support audio/video switching
generally using component video and accompanying audio (Toslink, Coax,
or L+R RCA) and few can use the analog audio substituted for H+V
sync supporting VGA/RGBHV. Analog Matrix Switchers are considered
stable and reliable and used in homes with multiple displays or
restaurants and sports bars, unlike HDMI based matrix switchers that can
be problematic when TV's of different resolutions are used. Matrix
Switchers are likely to be supported by the major control product
companies like Crestron, AMX, and Control4.
Switching of digital devices are rare due to the licensing and
functional feature requirements that support HDCP. We currently
offer products from Dtrovision that support 6x6, 9x9, and 18x18 designed
for professional environments. The DVI models used with Fiber Optic cables
can deliver up to 1080p transmission at single-link (1.65Gbps) for up to
at further than 50 ft. (900 Meter) lengths.

Features and Options
can be the ideal solution when automation is integrated into your
entertainment system. There are several control system interfaces
as listed below. Companion audio switching is another popular
feature for learning remote use. Below are list of features to
look for in your choice of switchers.
- Auto-sensing switches poll for active signal which triggers the
switching function. To optimize how this works, a priority
sequence is also used to allow two devices to be powered up in a
Controlled - An IR port present with or without remote can be the
lowest common denominator in the automation system, better combined with
hard wired front panel push button.
- The preferred interface for high level control, RS-232 is used for
complex automation commands that control macro laden programming.
Whole house systems such as AMX, Crestron, as well as a whole new legion
of automation pioneers appearing on the market ushers in more
competitive pricing in the control arena.
Switching - Companion audio switching helps to ease the automation
programming allowing both to be done simultaneously. Sometimes
overlooked, and one of the more useful features is the presence of both
analog and digital audio options, especially in a home with children or
casual users that should be kept away from high end media systems.
Analog audio allows the use of speakers in a TV for casual watching or
Distribution- Few switchers, often a multiple output matrix units
offer amplification for distribution of A/V signals that require long
Scaling - Video processing or scaling is often done in the display,
but many enthusiasts add external scalers that often improve the image
quality, especially in digital panels that require more precise
resolution controls for non-standard native pixel grids. Many
scalers function as switchers as more manufacturers introduce products
that accept multiple digital sources (DVI or HDMI).
