3 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.
4 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.
5 USING THE 8240A AND 8250A IN ST AND -AL ONE 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.
6 “DIGIT AL IN AES/EBU” connector Use this female XLR connector for AES/EBU formatted digital audio input signals. This input is selected automatically when a valid digital audio signal is present, and overrides the analogue input.
7 The overload light (red) is activated by several events, • exceeding the maximum input range of the analog input • exceeding the maximum input range of the digital input with large probability .
8 Mounting options The vibration insulating Isolation Positioner/Decoupler™ (Iso-P od™) table stand allows tilting of the loudspeaker for correct alignment of the acoustic axis. The stand can be attached to three mounting points allowing vertical and symmetrical horizontal positioning.
9 This feature is designed to compensate for the boost often occurring at this frequency range when the loudspeaker is placed upon a meter bridge, table or similar reflective surface.
10 F unctions on Switch Group 2 Stored / Manual Ctrl This allows the selection between two basic methods of controlling the loudspeaker in the stand-alone mode. “MANUAL CTRL ” refers to controlling the loudspeaker using the controls on the loudspeaker’s back panel.
11 • Connect the GLM Control Network to the main loudspeakers. • Make a System Setup in GLM. It will consist of main loudspeakers as this is all the network can see, so suitable Rapid Cabling Presets are “Stereo Pair (Analog)” and “5.0 Surround System (Analog)”.
12 Guarantee Genelec 8240A and 8250A are supplied with one year guarantee against manufacturing faults or defects that might alter the performance of the loudspeakers.
