Experiment with speaker placement to obtain the best bass level and stereo imaging in your room. Figure 3. This figure shows an alternate layout, which may be more suitable for some rooms. [. . . ] The center rear channel is for a 6-channel system. HOME THEATER For front-channel use, place one speaker on the left and another on the right, along either side of the television monitor. Since the speakers are magnetically shielded, you can place them near the TV without worrying about the field distorting the TV picture. For surround-channel use, place speakers on bookshelves or stands alongside the listening position. Tour and Balcony are also wall-mountable. Final placement depends on room acoustics, availability of space and your listening preference (Figures 2 and 3). In 6- or 7-channel configurations, place the rear channel(s) behind the listening position, as shown in Figures 2 and 3.

Balcony Important Safety Notes · Proper selection of mounting hardware and installation of the wall brackets are the responsibility of the customer. · This product is not intended for ceiling mounting. 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. 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. Conversely, if you place the speakers closer to the walls, there will be more bass output. See Chart 1/8" (3mm) WIRING THE SYSTEM IMPORTANT: Make sure all equipment is turned off before making any connections. For speaker connections, use a high-quality speaker wire with polarity coding. The side of the wire with a ridge or other coding is usually considered positive polarity (i. e. , +). NOTE: If desired, consult your local JBL dealer about speaker wire and connection options. The speakers have coded terminals that accept a variety of wire connectors. The most common connection is shown in Figure 4. To ensure proper polarity, connect each + terminal on the back of the amplifier or receiver to the respective + (red) terminal on each speaker, as shown in Figure 5. [. . . ] Connect the ­ (black) terminals in a similar way. See the owner's guides that were included with your amplifier, receiver and television to confirm connection procedures. IMPORTANT: Do not reverse polarities (i. e. , + to ­ or ­ to +) when making connections. Doing so will cause poor imaging and diminished bass response. CARE OF YOUR SPEAKER SYSTEM Each JBL Venue Series enclosure has a wood-grain-vinyl finish that does not require any routine maintenance. [. . . ]
