This picture shows a wall cupboard
with its door fitted and closed.
The aerials are for the radio
microphones.
The rack cupboards that we supply have a removable door (once unlocked) for ease of operation during an intensive
period of use, such as a show, and removable side panels for ease of maintenance.
Standard rack system
Our SYS20 & SYS30 series hall systems are based around an industry
standard 19” rack system ‒ you get no bonus points for guessing that
the equipment panel mounting width is 19”.
There is also an easy to follow system for the height of equipment in the
cupboard: these heights are measured in ‘U’ units (1U is 1
3
/4” or 45mm).
A SYS20 is usually fitted in a 12U cupboard and the SYS30 into a 15U.
Therefore a 12U rack mount unit has panel height of 21”
and a 15U a panel height of 26
1
/4”.
All of the items fitted into the rack cupboard are screwed to the vertical front runners,
including panels, shelves, amplifiers etc. The overall system is very flexible and makes
it easy to provide bespoke configurations with additional components such as a
CD/USB player, graphic equaliser, loop amplifier or more radio microphones. Often a
larger cupboard is requested to allow space for future expansion of the system.
Overall size of rack mount cupboards: width = 600mm, depth = 500mm.
12U height = 640mm, 15U height = 775mm, 18U height = 910mm.
