GAIN REDUCTION meter. This meter indicates that the limiter has been put into operation and is
controlling the gain reduction. In this case, it might be wise to reduce the bass level with the LEVEL
control. It is also possible to use the limiter to create a desired effect. With the correct settings it is
possible to create a so-called loudness effect: At low volumes the ULTRABASS PRO creates additional
harmonics and extends the range of the used system and at higher volumes the limiter limits the strain
of the created subharmonics to free the maximum sound pressure level of the system.
Satellite section
The X-OVER function acts as a highpass filter in the stereo main path for use in combination with a
subwoofer. The activated highpass filter prevents the main speakers (now operating in a multiway active
system) from being overloaded by the generated low frequencies. If the X-OVER switch is set to SPLIT,
all low-range frequencies below 70 Hz are filtered in the stereo main path, and the newly generated low
frequencies are exclusively routed to the subwoofer via the subwoofer output.
However, if the X-OVER function is switched to FULL RANGE, the generated subharmonics can be
added to the original stereo signal by depressing the ULTRABASS switch. The low-frequency signal
remains present at the subwoofer output.
ULTRABASS switch. With the ULTRABASS switch the generated subharmonics can be led to the
satellite loudspeakers. This is usefull to create a smooth transition from subwoofer to satellite, or if no
subwoofer is used.
SATELLITE LEVEL control. This is the level control for the main speaker system in full range operation
and for the satellites in split (x-over) operation.
+
The level of added bass-frequencies present at the satellite output is not dependent on the
setting of the SATELLITE LEVEL control. Only the setting of the BASS LEVEL controls the level
of subhamonics.
LEFT / RIGHT OUTPUT LEVEL meter. With these level meters the left and right output level of the
ULTRABASS PRO can be monitored.
As mentioned before the ULTRABASS PRO has several controls which influence the sound characteristics of
the unit. The FREQUENCY, DYNAMIC PUNCH, SUBHARMONICS and BASS MODE controls change the
sound of the ULTRABASS PRO. The other controls govern how much of the effect is audible and how the unit
is connected. Please take the time to play around with the ULTRABASS PRO at home or “off line” to get the
feel of the possibilities it offers.
