SMK VRE 48 Setup Guide
The Extron SMK VRE 48 V-Rail Extension Kit allows the V-rails that ship with the SF Series
speakers to span 4' (1.2 m) tile grids. The extension bars use the same interlocks as the
modular V-rails that ship with the SoundField
®
XD speakers, allowing the pieces to snap
together (see the speaker user manual for further details).
The V-rail extension bar is connected between the two V-rail half sections that come with the
speakers (see the steps below).
1. Assemble the V-rail to the extension bar by tting the tab on the V-rail end into the
slot on the extension end 1.
2. Open the extension bar
until it locks together
with the V-rail 2.
3. Assemble the other V-rail
end to the extension bar
end by tting the slot on
the V-rail end onto the tab
on the extension end 3.
4. Rotate the V-rail end
until it locks together
with the extension bar 4.
