BS-678Wall Mount Speaker System APPEARANCE AND DIMENSIONAL DIAGRAM R6 (R 0. 24 ") 28.3 (1.11") Top View 3 – ø20 (ø0.79") 250 (9.84") 110 (4.33") 83.5 (3.29") 83.5 (3.29") 190 (7.48") 4") 0.2 (R R6 Fron View 3 – ø5 (ø0.2") RearViewDESCRIPTION SPECIFICATIONSThe BS-678 is a double-cone type speaker with a wooden cabinet Rated Input: 6W (100V line), 3W (70V line) Rated Impedance: 100V line: 1.7kΩ (6W), 3.3kΩ (3W), 6.7kΩ(1.5W),that has a stylish, compact and unobtrusive design and that delivers 13kΩ (0.8W)highly cost-effective performance. A push-in type input connector 70V line: 1.7kΩ (3W), 3.3kΩ (1.5W), 6.7kΩ(0.8W), 13kΩ (0.4W)allows easy cable connections and bridge wiring. The selectable Sensitivity (1W, 1m): 94dB (500 – 5,000Hz, pink noise)input impedance can be easily adjusted by changing the tap position Frequency Response: 150 – 20,000Hz (peak –20dB)of the unit’s transformer. 6" (16cm) double cone speaker unit ensures Speaker Component: 6" (16cm) double cone-typehigh-quality sound, making the BS-678 ideal for BGM and Applicable Cable: 600V vinyl-insulated cable (IV wire or HIV wire) Solid copper wire: ø0.8 – ø1.6mm (equivalent toannouncement applications. It can be installed in either a horizontal AWG 20 – 14)or a vertical orientation. Its structure permits direct wall installation 7-core twisted copper wire: 0.75 – 1.25mm2 (equivalent to AWG 18 – 16)with screws, making the speaker unit resistant to falling even if Connetion: Push-in connector (bridging terminal)outward force is applied to it. Finish: Baffle: HIPS resin, off-white (RAL 9010 or equivalent colour) Cabinet: Particle board with pvc sheet, off-white (RAL 9010 or equivalent colour) Grille: Surface-treated steel plate net, off-whiteFEATURES (RAL 9010 or equivalent colour)• Stylish, compact and unobtrusive design Dimensions: 250 (W) × 190 (H) × 110 (D) mm (9.84" × 7.48" × 4.33")• Quick and easy installation Weight: 1.7kg (3.75 lb)• High cost-effectiveness Accessory: Speaker mounting screw (4 × 35 (0.16" × 1.38")) × 2• Horizontal / vertical installation• Ideally suited for BGM and announcements Note: When mounting the BS-678 to plaster board walls be sure to use Wiring Diagram sufficient "anchoring type" bolts from Bridging Input Matching the local hardware store instead of the terminal connector transformer HOT HOT(black) 13kΩ supplied screws. 6.7kΩ 8Ω 3.3kΩ 1.7kΩ 0 COM COM COM(white)
