2. The optional PLASTER-RING BRACKET (or "mud ring") is identical to the New
Construction Bracket, with the addition of 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 either precut or cut with a rotary cutting tool. The sheet rock hole is
then plastered (or "mudded") up to the ring to create a seamless cutout.
NEW CONSTRUCTION BRACKETS
The model numbers for the New Construction Brackets for the Control 24C/CT Micro and
the Control 24CT MicroPlus are the same as the brackets for the Regular Control 24C & CT
ceiling speaker.
New Construction Bracket: MTC-24NC
Plaster Ring Bracket: MTC-24MR
USING INCL
UDED C-BRACKET WITH SHEETROCK
For most installations, the INCLUDED C-shaped backing plate provides adequate reinforce-
ment to the ceiling material, spreading out the clamping force from the tab clamps.
CUT
OUT SIZES
The speakers are packaged in cardboard cutout templates which can be used for scribing the
cutout hole onto your ceiling surface. The cutout size for the Control 24C/CT Micro and the
Control 24CT MicroPlus is the same as the Regular Control 24C & CT.
Cutout Size: 6.6 inches (168 mm)

- 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
