3. vent port – aktiv 08 is a vented box speaker system with a vent port on the rear panel. Make sure
you are not blocking the vent port (i.e. by putting the speaker too close to a wall) or the sound
colour will be changed.
4. volume control knob – use the volume control knob to set the proper input level from the sound
source. Make sure to setup all speakers accordingly. When set to the center position, the output
level is set to the recommended calibrated level to reach the most optimised dynamic response
(expecting a balanced XLR +4dBu or unbalanced TS -10dBV input signal).
5. treble attenuation adjustment – to match your aktiv 08 to certain room acoustic requirements, a
change in the treble attenuation can be made with this switch. The default and recommended setting
is 0dB and normally you can always keep it there. Always make sure to setup all speakers
identically.
6. bass roll off adjustment – this switch allows you to match aktiv 08 better to a subwoofer and in
special situations where the room acoustics require it. The default and recommended setting is 50Hz
and normally you can always keep it there. Always make sure to setup all speakers identically.
7. power switch – when you push the power switch, aktiv 08 will be turned on, and –surprise– it
will be turned off when you push the power switch again.
8. power port with ext. fuse – use this connector to plug in the detachable 3-circuit line cord that
connects to the power outlet. The connector contains a replaceable fuse (T2AL/250V).
9. AC Selection – you can select either 115V or 230V AC power according to your local
requirements. Make sure this is selected properly before you switch on aktiv 08 for the first time or
your equipment could be damaged.
10. power mode switch - you can select either STANDBY or ON. When set to ON, the unit will
always be turned on. When set to STANDBY, the unit will switch to power saving mode after a
while without any audio signal. The power saving mode is indicated by a red LED on the front
panel (instead of the blue power LED). When there is an audio signal again, regular operation
resumes. Please note that the POWER MODE switch is only available in models sold in certain
countries.
