The JBL MTC-SB2W is a bracket for installing the JBL Control SB2 Subwoofer onto a wall or into a corner. The bracket acts as an enclosed shelf upon which the SB2 sits. The
bracket’s outside lip and securing screws keep the subwoofer from sliding off or jumping out of the support.
Warning: This bracket is not intended to be used ANY other way.
Step 1: Install the bracket SAFELY to the building’s struct ur e. IT IS THE
RESPONSIBILITY OF THE I NSTALLER TO DETERMINE THE STRENGTH OF THE BUILDING STRUCTURE AND TO ENSURE THE SAFETY OF THE BRACKET INSTALLATION TO THE BUILDING STRUCTURE!
The bracket and Subwoofer MUST be oriented as show n in Diagrams 1 & 2.
Step 2: Remove the three (3) bottom screws on the front of the load-baffle of the Control
SB-2 (see diagram 3)
Step 3: Connect appropriate wires to Control SB2 terminal cup. Step 4: Set the Control SB2 into the bracket frame. Step 5: Secure the Control SB2 to the bracket by reinstalling the three (3) removed load-
baffle screws through the holes in the front of the bracket. Secure the screws into t he subwoofer. (see diagram 4).
Step 6: Apply a secondary safety strap between a secondary building structure point and
the subwoofer/bracket assembly as a backup support. The safety strap and all attachments must be capable of holding the product, keeping it from falling in case of catastrophic failure of the primary bracket mounting to the building structure.
Hints for Locating the Control SB- 2 f or Pr oper Output Sensitivity – The placement of the Control SB-2 can be used as a tool for adjusting the subwoofer output level to match those of the satellite speakers. Positioning the SB-2 close to the junction of 3 boundaries (ceiling/wall/wall junction or floor/wall/w all junction) yields maximum output sensitivity. Placement at the junction of 2 boundaries (wall/wall junction) reduces the subwoofer sensitivity by 3dB. Placement along a flat wall further reduces subwoofer sensitivity by another 3dB for better tonal balance with less efficient or high impedance sat ellite systems.
