The OPALine-82 features a switchable input impedance of either 8 ohms or 32 ohms. In 32 ohm mode a total of 16 enclosures may be connected to a single amplifier channel (with 2 ohm rating). This allows the OPALine-82 to be used in distributed designs without the need for input transformers. The 8 ohm setting allows the enclosure to be used in performance applications where maximum amplifier power is required.
Several accessories are available for the OPALine-82 speakers, including the PTB-82 pan/tilt bracket, as well as the SB-82 shackle bracket for ceiling and structural mounting of the OPALine-82. See the downloads area of this page for available accessories and installation guides.
The OPALine-82 can also be used with the On Point Audio OPA-151SA high performance powered subwoofer when extended bandwidth and additional bass is required. The OPA-151SA includes a high performance DSP based preamp that provides complete processing functions. When used without the powered subwoofer the system offers a low frequency bandwidth of 150Hz, making the system ideal for high intelligibility vocal reproduction. A standard telescoping pole typically used with this subwoofer and a portable speaker can be substituted with the On Point accessories P1, or P2 (and additional accessories) when being used as a portable systems with the OPALine-82 speaker system.
