Setting the input sensitivity

Mounting options

The vibration insulating Isolation Positioner/Decoupler™ (Iso-Pod™) 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.

Genelec 8240A and 8250A can be fitted to König & Meyer loudspeaker mounts on two sets of M6x10

mmthreaded holes on the back of the enclosure. On the base of the enclosure is an M10x10 mm threaded hole which can be used for securing the loudspeaker to its base. Do not use this thread for mounting the loudspeaker on a microphone stand which has a 3/8" UNC thread. A wide variety of ceiling and wall mounts is available through your Genelec dealer.

The loudspeaker level sensitivity functions for both analog and digital input. The sensitivity can be matched by adjusting the rotary Level control together with the System Level switches located in the switch group

2.(switches 6 and 7). The switches provide attenuation levels of -10 dB (sw. 6 ON), -20 dB (sw. 7 ON) and -30 dB (both switches ON) The combined attenuation ranges from 0 to -42 dB.

Functions on switch group 1 (Tone controls)

Switch group 1 (the upper switch group) comprises the tone controls that can be used to adjust the frequency response of the system in stand-alone mode to match the acoustic environment. The controls are labelled "TREBLE TILT", "BASS TILT", "BASS ROLL-OFF" and “DESKTOP”. The factory settings for these controls are all "OFF" to give a flat anechoic response. Note that these controls have no effect when switch 1 “STORED/MANUAL CONTROL” on switch group 2 is set to “STORED” or when the loudspeaker is connected to the Genelec loudspeaker control network.

Bass Roll-Off control

Bass Roll-Off control (switches 1 and 2) affects the low frequency roll-off of the loudspeaker and attenuates its output near the cut-off frequency. Attenuation levels of -2 dB (sw. 1 ON), -4 dB (sw. 2 ON) or -6 dB (both switches ON) can be selected.

Bass Tilt control

The Bass Tilt control switches (swiches 3 and 4) offer three attenuation levels for the bass response below 800 Hz, usually necessary when the loudspeakers are placed near room boundaries. The attenuation levels are -2 dB, -4 dB and -6 dB.

Desktop low frequency control

The desktop low frequency control (switch 5) attenuates the bass frequencies around 160 Hz by 4 dB.
