ALL included support brackets, C-plate and tile rails
MUST be used when installing into suspended ceiling tiles.
FOR SAFETY: IMPORTANT TO USE BRACKETS
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
upper 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.
The installation system has been designed so that the entire installation can be accom-
plished 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 Ceiling Hole. Cut out the hole size either by tracing the cardboard cutout tem-
plate and cutting the hole or by using a circular cutter set to the cutout sizes listed above. Pull
the wiring through the cutout hole.
Guide to the Pins for Connection - The locking input connector contains 7 terminals,
as marked above the connector. The pin functions are listed on the label located on the
terminal cover plate.

Hole Cutout
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.

- For control 24ct micro and the control 24ct microplus connect the negative input to the common terminal and connect the positive input to the appropriate tap the input pins correspond to the taps of the transformer indicated on the label above each connec tor for example if the system is being driven from a 70v distributed line and the 2w tap is the desired connection the positive input would be made to the input marked 2w violet the negative connection would be made to the common pin 9
- Guide to the pins for connection the locking input connector contains 7 terminals as marked above the connector the pin functions are listed on the label located on the terminal cover plate 9
- On the control 24c micro low impedance version connect the negative wire to the terminal and connect the positive wire to the terminal all other pins are no connection 9
- Paralleling input terminals it is common to run two sets of wires one set is the input to the speaker and the other is the feed to the next speaker in this case simply par allel the two sets of wires to the same terminals on the speaker s terminal block 9
- Step 4 add included metal strain relief as necessary the control 24c ct micro and the 24ct microplus are equipped with two locations where the installer can affix strain relief con nectors one is on the back of backcan and one is on the side for applications with shallow access the location of these two attachment points is shown on the product feature identification on page 3 the installer can attach a wide variety of installer provided fittings to these points if the included equipment is not adequate for the particular installation refer to figure 6 shows the strain relief included with the control 24c ct micro and control 24ct microplus 9

- When using a distributed line system the distribution amplifier is incapable of producing an output voltage higher than its rating 70 v or 100 v depending on geographic region this is a peak voltage rating as such loudpseakers utilizing distribution transformers are not rated for voltage inputs in excess of those amplifier specifications 13
