User manual JBL ES90BK

[. . . ] · Position each speaker so that the tweeter is approximately at ear level. · Generally, bass output will increase as the speaker is moved closer to a wall or corner. · Refer to "Home Theater" below if you also plan to use the speakers for home theater reproduction. Figure 2. This overhead view shows a typical home theater plan. [. . . ] The customer is responsible for proper selection and use of mounting hardware (available through hardware stores), to properly and safely wall-mount the speakers. THESE PRODUCTS ARE NOT INTENDED FOR CEILING MOUNTING. CHANGING THE FEET ES80, ES90, ES100 The ES80, ES90 and ES100 feature attractive outboard feet, installed at the factory. However, if you would like to replace them with the less visible inboard feet (included), follow the instructions below. Remove the four feet on the bottom of the speaker by loosening the two screws in each foot. Keep the screws for later use. 10" (254mm) 1/8" (3mm) Two no. 8 round-head or pan-head screws should be used per loudspeaker. The screw head should be between 5/16 inch (8mm) and 1/4 inch (6. 3mm) in diameter, and the screw should be at least 2 inches (50mm) in length. When installing screws in any wall, always use properly selected wall anchors. Attach two of the four self-adhesive rubber pads that came with the loudspeaker to the back of the enclosure in the two bottom corners so that the cabinet is spaced evenly from the wall. Select a suitable mounting location on a wall. (The ceiling is not a suitable mounting location. ) Drill two pilot holes, appropriately sized for the specific self-tapping screw or wall anchor that you will be using. The holes should be 10 inches (254mm) apart. The holes should be 3/4 inch (19mm) below where you want the top of the enclosure to be positioned. Use a carpenter's level to ensure that the holes are even and that the speaker will mount on the level. 2. Attach the black inboard feet to the outer (closest to front of speaker for front feet, closest to rear of speaker for rear feet) holes, from which you just removed the feet, using the same screws you just removed. Hand-tighten securely, using a handheld Phillips (+ tip) screwdriver. Do not use a powered screwdriver of any type. Install the two screws into either a wooden wall stud or anchor, and tighten them until the back of each screw head is about 1/8 inch (3mm) from the wall. Install the loudspeaker by slowly moving the cabinet toward the screws so that the screw heads clear the larger circular portion of the two keyholes. Once both screw heads have entered the keyholes, the loudspeaker should gently be lowered onto the screw shafts. Check that the loudspeaker is firmly locked onto the screws by gently pulling the speaker down and forward. 4. CAUTION: Floorstanding (tower) loudspeakers have a high center of gravity and may become unstable and tip over during earthquakes, or if rocked, tipped or improperly positioned. If this is a concern, these speakers should be anchored to the wall behind them, using the same procedures and hardware customary for anchoring bookcases and wall units. The customer is responsible for proper installation and proper selection of hardware. 3 WIRING THE SYSTEM IMPORTANT: MAKE SURE ALL EQUIPMENT IS TURNED OFF BEFORE MAKING ANY CONNECTIONS. [. . . ] If not, check all wiring connections or consult the authorized JBL dealer from whom you purchased the system for more help. The amount of bass you hear and the stereo-image quality will be affected by a number of different factors, including the room's size and shape, the construction materials used to build the room, the listener's position relative to the speakers, and the position of the speakers in the room. STANDARD CONNECTION Standard Connection Figure 5. Wiring diagram shows polarity connections for one channel of a stereo or home theater system. Listen to a variety of music selections and note the bass level. If there is too much bass, move the speakers away from nearby walls. [. . . ]
