User manual BIAMP IWA250 BACK-BOXES

[. . . ] IWA 250 ­ Backbox Installation Backbox Installation: Backboxes are available for mounting the IWA 250 chassis in the wall, flush with the finished wall surface ("IWB" In Wall Box), or for mounting on the surface of the wall, with a 4" projection ("SMB" - Surface Mount Box). [. . . ] The "IWB" can be mounted between standard 16" center studs, using the six mounting holes on each side of the box. The "SMB" can be mounted onto standard 16" center studs, using the four outer-most "keyhole" slots, or onto other suitable surfaces, using the six inner-most "keyhole" slots. Wire Routing: Wiring that carries signals of dramatically different voltages must be separated by as much distance as possible. Microphone and line level wiring should never be run with loudspeaker or power wiring. To reduce the potential of crosstalk or oscillations that could damage the amplifier, never bundle the microphone and line level cables with loudspeaker or power cables. It is recommended that all loudspeaker wiring enter the backbox at the upper right "knock-out", and route through the cable tray. It is recommended that wiring for the microphone and line inputs should enter the backbox at the lower right "knock-out", and route under the bottom edge of the chassis. NOTE: AC power should enter the backbox at the bottom left "knock-out" (a standard AC duplex outlet, with enclosure and cover, is provided). [. . . ] Constant voltage outputs (25, 70. 7, or 100 volts) can tolerate lighter gauge cables or longer cable runs (check an appropriate line loss chart for specific application requirements). 1 IWA 250 ­ Backbox Installation IWB (In Wall Box) SMB (Surface Mount Box) 5Jul06 585. 0044. 90A 2 [. . . ]
