2) The optional PLASTER-RING BRACKET or “mud ring”
(MTC-19MR) contains a circular offset, forming a 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 is then plastered (or “mudded”) up to the
ring to create a seamless cutout.
USING INCLUDED C-BRACKET WITH SHEETROCK
For most installations, the INCLUDED C-shaped backing
plate provides adequate reinforcement to the ceiling material,
spreading out the clamping force from the tab clamps.
CUTOUT SIZE
Packaged with the speakers are cardboard cutout templates
for scribing the cutout hole onto your ceiling surface. The
cutout size diameter for the Control 226C/T is 12.1 inches
(307 mm).
Control 226C/T PREPARATION
The installation of the Control 226C/T can be accomplished,
if necessary, without requiring access above the ceiling.
Bracketry for use with either suspended ceilings or sheetrock
ceilings is included. The speaker 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 speaker for ultra-fast snap-on
installation.
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 226C/T
ceiling speaker.
However, a particular procedure that is sometimes used for
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 BRACKET (MTC-
19NC) is 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.

Control 226C/T INSTALLATION
The installation system has been designed so that the entire
installation can be accomplished from beneath the ceiling,
for instances when access above the tile is not possible or
practical. However, in some cases it may be easier with
removable ceiling tiles to access from both the top and bottom
of the ceiling tile during various phases of the installation.
Step 1 – Cut the Hole. Cutout the hole size either by tracing
the cardboard cutout template or with a circular cutter set to
the cutout sizes listed above. Pull the wiring through the
cutout hole.
Step 2 – Insert Backing Hardware Through the Hole.
Packaged with the speakers are two types of backing
hardware – a C-shaped backing-plate bracket and two tile
rails.
Suspended Ceilings – Insert the C-plate through the hole
cut in the ceiling tile. Place the C-plate around the hole with
the tabs located as shown on Figure 4. Insert the tile rails
through the cut hole in the ceiling tile. Snap the two rails into
the two tabs in the C-plate and align the rails so that the
ends extend OVER the T-channel grid on the side of the tile.
Secure the rails onto the C-bracket tabs by inserting a screw
though each tab into the rail. This can all be accomplished
from below the ceiling tile, if necessary.
FOR SAFETY: IMPORTANT TO USE BRACKETS.
ALL included support brackets – C-plate and tile rails
-- MUST be used when installing into suspended ceiling
tiles.
Tile Rails: The tile rails are designed to fit either standard
24-inch wide tiles or 600-mm wide tiles. The tile rail pieces
do NOT physically attach to the T-grid struts. Instead, the
inverted-V shape at the ends of the rails sit OVER the T-grid
strut. During normal operation, the rails are supported by
the edge of the tile. In the unlikely even that the tile comes
out or falls apart, the ends of the support rails are designed
to catch onto the T-grid, providing secure support to hold the
loudspeaker assembly in place.
Vibration Reduction: These loudspeakers can generate
substantial vibration, which can cause buzzing of the ceiling
materials or structure. Depending on the character of the
ceiling tile and structure, the installer might need to place
neoprene or other dampening material under the tile rails or
the edges of the tiles to eliminate rattles.
Cutout Placement: The tile rails are pre-punched with
attachment holes along their length. Placement is not limited
to the center of the tile as is the case with many other tile rail
support systems.
Non-Suspended Ceiling Types – The C-bracket can be
optionally used by itself to shore up the ceiling material and
to spread out the clamping force from the tab clamps. Insert
the C-plate through the cut hole in the ceiling and place it on
the back side of the hole before inserting the speaker.

JBL Professional Control 200 Series
Control 200 Series Loudspeakers include Euroblock or
Phoenix-type locking input connectors that allow the system
to be “pre-wired” before the speakers are installed.
Connecting the Wiring to the Euroblock -- Connect the
wiring to the removable locking connector
that is INCLUDED with the speaker by
stripping the insulation back about 5 mm
(about 3/16 inch), inserting the bare end of
wire into the connector and screwing down
the hold-down screw until tight using a small
flatblade screwdriver. Tighten any unused
screws to avoid vibration. Using terminal
block connectors allows the system to be pre-
wired before final installation of the drivers.
When wiring Control 200 Series loudspeakers,
always use proper electrical wiring practices
in accordance with your area’s building codes
and regulations.
Control 226C/T
Connecting the Input Terminal Block on the Control
226C/T -- The input terminal cover on the Control 226C/T
is fitted with a conduit connector for running and securing
wiring or conduit to and from the unit. To wire the unit:
1. Loosen the screw on top of the input terminal cover and
then remove (and save) the input terminal cover screw on
the side of the can.
2. Swing open the input terminal cover and remove the
euroblock connector.
3. Insert the bare end of wire into the euroblock connector
and secure the wires with the hold-down screws. (see
Connecting the Wiring to the Euroblock)
4. Loosen the conduit
connector on the input
terminal cover and insert
the wired euroblock
connector through the
conduit connector opening.
Connect the euroblock to
the matching receptacle.
5. Shut the input terminal
cover and replace and
tighten the terminal cover screws.
6. Allowing sufficient strain relief for the input wiring and re-
tighten the conduit connector on the terminal cover.

NOTE: The input terminal
cover on the Control 226C/T
also includes a .75 in (19 mm)
knockout for an additional
conduit clamp. This knockout
point can be used in addition
to the conduit connector
located on the top of the can
and is useful for wiring loop-
thru runs or when access
is limited on the top of the
Control 226C/T can.
Guide to Connection Pins on Control 226C/T -- There
are two (2) removable locking input connectors with two (2)
terminals on each. The pin functions are listed on the label
located on the cover on the rear of the can.
On the Control 226C/T, connect the negative wire to the “-”
or pin 2 and connect the positive wire to “+” or pin 1. Pins 1
& 2 are looped to pins A & B, respectively (Pin 1 connects
to Pin A and Pin 2 connects to Pin B) inside the speaker.
Pins A & B are intended as loop-through connections to
subsequent loudspeakers. (See next page Using Loop-
Through Terminals).
To select the operating mode or desired output tap of the
loudspeaker, simply rotate the tap selector switch located on
the front of the baffle to the desired setting.
Note: Both 70V/(100V) connections and low impedance
connections are made at the same pins. When using the
transformer tap selections, be sure that the power amplifier
is set on 70V/(100V) Mode and the leads feeding the system
are connected to 70V/(100V) outputs on the amplifier.
Control 227C & Control 227CT
Guide to Connection Pins on Control 227CT -- The
removable locking input connector contains 5 terminals, as
marked on the connector. The pin functions are listed on the

On the Control 227CT, connect the negative input to the
“Common” terminal and connect the positive input to the
appropriate tap. For example, if the system is being driven
from a 70V Distributed Line and the 30W tap is desired, the
positive input would be made to the input marked 30W and
the negative connection would be made to the “Common”
pin. The input pins correspond to the taps of the transformer
indicated on the label below each connector.
Guide to Connection Pins on Control 227C -- The
removable locking input connector contains 4 terminals, as
marked on the connector. The pin functions are listed on the
label located on the crossover frame.
Pins 1 & 4 are the “+” and “-” inputs to the loudspeaker.
Connect the negative wire to “-” or pin 4 and connect the
positive wire to “+” or pin 1. Pins 1 & 4 are looped to pins 2 &
3, respectively (Pin 1 connects to Pin 2 and Pin 3 connects
to Pin 4) inside the speaker. Pins 2 & 3 are intended as loop-
through connections to subsequent loudspeakers. There are
two possible hookup schemes for connecting subsequent
speakers, determined by the desired result from the circuit
whenever this speaker’s connector gets disconnected during
troubleshooting.
Hookup Schemes for Subsequent Speakers
Choose whichever of the following hookup patterns best
accommodates your installation.
1.) Paralleling Input Terminals -- Connect the wire pair of
the subsequent speaker to pins 1 & 4 (in parallel with the
input wire pair). Whenever the connector is pulled out of the
speaker for troubleshooting, subsequent speakers will stay
connected. This can be useful during troubleshooting to be
able to disconnect a single loudspeaker at a time. In this
hookup scheme, no wires get connected to pins 2 & 3.

GRILLES, MAINTENANCE & CONTACTING JBL
Painting the Grille -- The optional MTC-RG6/8 grille for
Control 227C/CT loudspeakers features a powder coated,
satin finish paint (RAL 9016 - Pantone equivalent 11-
0602TPX) and can be painted to match any decor. This
should only be done when the grille has been removed from
the loudspeaker and back can assembly.
For best results, a spray paint technique is recommended.
If the grille is rolled or brush painted, the grille perforations
may become clogged with paint and poor sound quality may
result. When painting the Control 226C/T grille, remove the
backing grille cloth to avoid paint clogs or diminished sound
quality reproduction.
To avoid damage when removing the Control 226C/T grille,
use a scratch awl, flatblade screw driver, or similar tool to
GENTLY pry the grille from the baffle at one of the dog ear
points.
Maintenance -- No maintenance is required when assembled
in accordance with the instructions and wiring guidelines
