CONTROL 40 SERIES PREPARATION

The installation of the Control Contractor 40 Series in- ceiling loudspeakers can be accomplished, if necessary, without requiring access above the ceiling. Bracketry for use with either suspended ceilings or sheetrock ceilings is included (see below for additional details on the Control 42C). The loudspeaker is held securely in place via mounting ears which lock into place. Inputs are attached to a removable locking connector (included) which can be prewired before installing the loudspeaker for ultra-fast snap-on installation.

The lightweight Control 42C (0.7 kg / 1.6 lbs) includes a C-ring but does NOT include tile rails. In the event that tile rails are required, they are available as an optional accessory (MTC-Rail).

OPTIONAL PRE-INSTALLATION BRACKETS

IN MOST CASES, NO BRACKETS OTHER THAN THE ONES INCLUDED WITH YOUR SPEAKER ARE REQUIRED. Everything needed for most installations of these loudspeakers is provided with your Control Contractor 40 Series in-ceiling loudspeakers.

Installation into sheet rock (typically gypsum board) can be facilitated by the use of JBL’s optional preinstallation brackets before the sheetrock is installed. The preinstallation bracket provides a bracket to which wiring can be tied behind the sheetrock and it can function as a cutout template when many cutouts are to be made in a production-line style installation. Two types of pre- installation brackets are available from JBL Professional as optional accessories:

1)The optional NEW-CONSTRUCTION BRACKETS (available options and listed below) are made of flat sheet metal, with wings to attach to the building structure. Holes are drilled for nails or screws at 16 inches (406 mm) and 24 inches (610 mm) on-center. Additional holes can be drilled by the installer at other spacings up to a maximum of 24-3/4 inches (630 mm) apart. Sheet rock installs over the bracket, and the bracket provides a template for blind cutout of the hole in the sheet rock. The sheet rock is typically cut with a router-type cutting tool, using the bracket ring as a cutout guide.

MTC-47NC for the Control 47C/T & Control 47LP MTC-19NC for the Control 47HC & Control 40 CS/T

2)The optional MUD-RING BRACKET (available options and listed below) contains a circular offset, forming an edge guide for sheet rock plastering. The bracket has wings that attach to the building structure. Sheet rock is typically precut, then the sheet rock hole can be plastered (or “mudded”) up to the ring to create a seamless cutout.
