the three tone control switch groups ‘treble tilt’, ‘bass tilt’ and ‘bass roll-off’ on the rear panel of the amplifier. The factory settings for these controls are ‘All Off’ to give a flat anechoic response. See Table 1 for sug- gested tone control settings. Figure 5 shows the effect of the controls on the anechoic response. Always start adjustment by setting all switches to ‘OFF’ position. Then set only one switch to the ’ON’ position to select the response curve needed. If more than one switch is set to ‘ON’ (within one switch group) the attenuation value is not accurate.

Vertical / horizontal mounting

The speakers are normally delivered set up for vertical mounting. Horizontal mount- ing should be avoided due to the increased likelihood of early reflections that degrade the the direct sound. If horizontal mounting is needed the DCW plate may be rotated so that the Genelec logo remains horizontal by removing the four corner screws of the DCW and carefully lifting and turning the DCW.

Console top mounting

If the 1031A’s are used for near field monitor- ing, avoid mounting them on the meter bridge of the console. Instead position the speakers slightly behind the console by using floor stands or wall mounts. This prevents the first reflections from the console surface from coloring the sound.

Overload indicators

The speaker is provided with two status LED's marked 'OVL' and 'ON'. The green ON-LED when lit indicates that the speaker is ready for use. The red OVL-LED indicates that the amplifier is overloaded or the driver protection circuit is activated. In both cases reduce the signal level so that the LED stops blinking. If the OVL-LED stays on constantly it indicates that the amplifier thermal protection is activated. Let the amplifier cool down and check that the ventilation at the rear side of the speaker is not blocked. There should be a clearance of more than 4" (10cm) between speaker rear and any solid surface.

Maintenance

No user serviceable parts are to be found within the amplifier unit. Any maintenance or repair of the 1031A unit should only be undertaken by qualified service personnel.

Safety considerations

Although the 1031A has been designed in accordance with international safety standards, to ensure safe operation and to maintain the instrument under safe operating conditions, the following warnings and cau- tions must be observed:

1.Servicing and adjustment must only be performed by qualified service personnel. The amplifier’s rear panel must

not be opened.

2.Do not use this product with an unearthed mains cable as this may lead to personal injury.

3.To prevent fire or electric shock, do not

expose the unit to water or moisture. Do not place any objects filled with liquid, such as vases on the speaker or near it.

4.Note that the amplifier is not completely disconnected from the AC

mains service unless the mains power cord is removed from the amplifier or the mains outlet.

WARNING!

This equipment is capable of producing sound pressure levels in excess of 85 dB, which may cause permanent hearing damage.
