Tubes do not however have the same task in a recording studio as in an overdriven guitar amp, where the
considerably higher saturation of the tube(s) leads to a full and often deliberate modification of the input signal
(in many cases combined with a heavy increase in noise floor levels). In the studio more subtle effects are
needed. Here, tube circuits add life to the signal’s tonal character and increase its power to make itself heard.
Often, tubes also increase the signal’s perceived loudness (in relation to the unprocessed signal), i.e. the
perceived loudness goes up although the volume level remains the same. This is because the dynamic range
of the applied audio signal is limited by the tube circuit, while the amplitude of the signal with the lowest
loudness is raised. Thus, increasing tube saturation produces a slight compression effect over the entire
dynamic range.
A similar effect can be perceived when analog tape is saturated. This saturation effect also compresses the
recorded audio material and produces additional harmonics.
The BEHRINGER MODULIZER PRO is equipped with tube emulation algorithms that due to extensive re-
search deliver very subtle and natural sound effects. These newly developed algorithms are capable of deliver-
ing both the subtle nuances of a tube as the strong coloration as produced by heavy saturation.
5. INSTALLATION
Your BEHRINGER MODULIZER PRO was carefully packed in the factory and the packaging was designed to
protect the unit from rough handling. Nevertheless, we recommend that you carefully examine the packaging
and its contents for any signs of physical damage, which may have occurred in transit.
+
If the unit is damaged, please do not return it to us, but notify your dealer and the shipping
company immediately, otherwise claims for damage or replacement may not be granted.
Shipping claims must be made by the consignee.
5.1 Rack mounting
The BEHRINGER MODULIZER PRO fits into one standard 19" rack unit of space (1 3/4"). Please allow at least
an additional 4" depth for the connectors on the back panel. Be sure that there is enough air space around the
unit for cooling and please do not place the MODULIZER PRO on high temperature devices such as power
amplifiers etc. to avoid overheating.
5.2 Mains connection
The mains connection of the MODULIZER PRO is made by using a mains cable and a standard IEC recep-
tacle. It meets all of the international safety certification requirements.
+
Please make sure that all units have a proper ground connection. For your own safety, do not
remove the ground connection within the units or at the supply, or fail to make this connection
at all.
Before you switch on the unit, check that it is configured to match your AC mains voltage requirements. If it
does not comply, then it is necessary to switch the operating voltage to the correct supply requirements
BEFORE turning on the unit, otherwise the unit could be severely damaged. You will find this combined fuse
holder/voltage selector at the back, adjacent to the IEC receptacle. IMPORTANT: This does not apply for
general export models which are built for one operating voltage only.
The AC voltage selection is defined by the position of the fuse holder. If you intend to change the operating
voltage, remove the fuse holder and twist it by 180 degrees before you reinsert it. Matching the two markers
monitors the selected voltage.
+
If the unit is switched to an other operating voltage, the ruse rating must be changed. See the
technical specifications in the appendix.
A safety fuse protects the unit from serious defects. If the fuse blows, this is a warning sign and always
indicates that the circuit is overloaded. The fault must always be repaired before the fuse is replaced. If the
safety fuse is faulty and needs replacing after the unit is repaired, please make sure that you replace it only
