INTRODUCTION

Congratulations and a thank-you for the purchase of this Genelec 8200 Series DSP Loudspeaker. These
systems are designed to integrate easily into the digital production environment. There are several ways
to configure and operate the DSP loudspeakers for a wide variety of high quality audio applications. The
loudspeakers also have analog inputs, making them versatile and intelligent replacements for analog
loudspeakers.

This manual addresses setting up and using the 8240A and 8250A DSP loudspeakers in stand-alone
mode without the Genelec Loudspeaker Manager GLM™ and the proprietary Genelec loudspeaker
control network. Use with the GLM™ is described in the DSP System Operating Manual.

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
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.

USING THE 8240A AND 8250A IN STAND-ALONE MODE

The 8240A and 8250A accept both analogue line level input signals and AES/EBU formatted digital input
signals.

When the 8240A and 8250A are not connected to Genelec loudspeaker control network, they operate
in the stand-alone mode. However, settings made with the Genelec Loudspeaker Manager software can
be saved into each loudspeaker and applied even when the network is disconnected by setting
“STORED/MANUAL CONTROL” on switch group 2 of each loudspeaker to position “STORED.”

This manual concentrates on using the 8240A and 8250A without the control network. All issues concerning
use with the network are explained in detail in the System Operating Manual provided with the GLM™
Loudspeaker Manager software kit.

Connections

Each loudspeaker is supplied with a mains cable, one 5 m GLM network cable and an operating manual.
Before connecting up, ensure that the mains switch is off.

“MAINS INPUT” connector
