harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.

Increase the separation between the equipment and receiver.

Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

Consult the dealer or an experienced radio/TV technician for help.

Modifications not expressly approved by the manufacturer could void the user’s authority to operate the equipment under FCC rules.

SYSTEM

Genelec 8240A and 8250A DSP Loudspeakers are designed for precise monitoring of 24 bit/192 kHz AES/EBU digital audio signal or line level analog audio signal. They are fully compatible with Genelec Loudspeaker Manager GLM™ and the proprietary Genelec loudspeaker control network, and Genelec 7260A, 7270A and 7271A DSP Active Subwoofers, but can also be used independently of these. The 8240A and 8250A feature high SPL output, low colouration and broad bandwidth in a small enclosure size. They are suitable for a wide variety of tasks, such as near field monitoring, mobile vans, broadcast and TV control rooms, surround sound systems and home studios. The Minimum Diffraction Enclosure™ (MDE™) and advanced Directivity Control Waveguide™ (DCW™) technologies provide excellent frequency balance even in difficult acoustic environments.

Drivers

The bass driver dimensions are 165 mm (6 1/2”) and 205 mm (8") for 8240A and 8250A respectively. The long, flow optimized reflex tube has a large cross sectional area and terminates with a wide flare at the back of the enclosure. The high frequency driver is a 19 mm (3/4”) metal dome on the 8240A and a 25 mm (1") metal dome on the 8250A. All drivers are magnetically shielded.

Amplifiers

The amplifier unit is mounted in the rear of the loudspeaker enclosure. The unit incorporates special circuitry for driver thermal overload protection. Variable input sensitivity allows accurate level matching to console output section.
