User manual GENELEC 6040A

[. . . ] Uniform dispersion control is achieved with the revolutionary DCWTM Technology pioneered by Genelec, which also results in perfect phase and delay uniformity at the crossover frequency. Magnetic shielding is standard on the 6040A to ensure minimal interference with TV screens and computer displays. CROSSOVER The active crossover network consists of two parallel bandpass filters. Acoustically, the filters are complementary and the slopes are 24­32 dB/octave. [. . . ] If the ratio of direct sound to reflected sound is greater the listener is then able to listen to more of the material and less of the room effects. Subjectively this is perceived as superior stereo imaging. INSTALLATION Each 6040A speaker is supplied with a mains cable, a set of pads (attached) and spikes for the speaker base and an operating manual. After unpacking place the speaker in its required listening position. Before connecting up, ensure that the mains switch is off and the mains voltage selector set to your local voltage. Audio input is via a 10 kOhm balanced XLR connector or an unbalanced RCA connector at the speaker base. Do not use both input connectors at the same time. Once the audio and mains connections have been made, the speakers are ready to be switched on. REMOTE CONTROL AND AUTOSTART The 6040A has a provision for remote ON/STANDBY switching by remote control or automatic signal sensing. Two pairs of connectors are provided at the base of the speaker next to the signal input connectors, pins 1 and 2 for a 12 V DC trigger type remote control and pins 3 and 4 for an external switch or relay type control. Do not connect two remote controls at the same time. The remote control function must be activated by turning the "REMOTE CONTROL" dip switch on the base panel to "ON". If a remote control is not used, the "autostart" function provides automatic ON/STANDBY switching by signal sensing. Switch the "AUTOSTART" dip switch to "ON" and "REMOTE CONTROL" dip switch to "OFF" to activate the function. The "Remote control" function overrides "autostart" so it must be deactivated when using "autostart". "Autostart" switches the speaker to "STANDBY" mode if an input signal has not been detected for approximately twenty minutes, and back to "ON" mode when the signal returns. SETTING THE VOLUME CONTROL The input sensitivity of the speakers can be matched to the output of the preamplifier by adjusting the sensitivity control on the speaker base panel. USING THE TONE CONTROLS The response of the 6040A can be adjusted to overcome acoustical problems in the listening room. Excessive bass level often results if the speakers are placed near a wall or into a corner. Treble can be dull or too bright depending on the acoustical damping characteristics of the room etc. These effects can be corrected by adjusting the tone controls on the speaker base panel. [. . . ] · This equipment is capable of producing sound pressure levels in excess of 85 dB, which may cause permanent hearing damage.
