Autostart And Remote Control
The 4030B is equipped with an Autostart function,
which automatically turns the amplifier to Standby
mode if an input signal has not been detected for
approximately 1 hour.
The amplifier mode can also be switched by a
12 V DC trigger type remote control. The remote
control wires can be connected to the first two
(starting from left) poles of the Phoenix connec-
tor (See Figure 2 for the connector pin sequence).
Remote control overrides the Autostart function.
Level control
The input sensitivity of the loudspeaker can be
matched to the output of the signal source by ad-
justing the level control on the rear panel.
Setting the tone controls
The frequency response of the Genelec 4030B
can be adjusted to match the acoustic environ-
ment by setting the tone control switches on the
rear panel. The controls are “Treble Tilt”, “Bass
Tilt” and “Bass Roll-Off”. An acoustic measuring
system such as WinMLS or comparable is recom-
mended for analyzing the effects of the adjust-
ments, however, careful listening with suitable
test recordings can also lead to good results if a
test system is not available. Table 1 shows some
examples of typical settings in various situations.
Figure 4 shows the effect of the controls on the
anechoic response.
