FUSE HOLDER / VOLTAGE SELECTION
. Before connecting the T1951, confirm that the voltage
display matches your local mains voltage. When replacing the fuse, you must always use the same
type. In many units the fuse holder can be installed in one of two positions, allowing you to switch
between 230 V and 115 V. If you wish to operate a unit outside Europe at 115 V, then a stronger fuse
must be used (see chapter 6 SPECIFICATIONS). The mains connection is made via the IEC
receptacle. An appropriate mains cable is included.

AUDIO IN
. These are the audio inputs of your TUBE ULTRA-Q, available both as balanced 1/4" TRS and
XLR connectors.
15
AUDIO OUT
. These are the audio outputs of your TUBE ULTRA-Q. Matching 1/4" TRS and XLR
connectors are wired in parallel. The automatic servo function recognizes balanced or unbalanced
connection and automatically compensates for the difference in level (correction 6 dB). The BEHRINGER
OT-1 output transformer is optionally retrofitable.

2.1 Introduction
The BEHRINGER TUBE ULTRA-Q gives you a combination of all technical properties both of parametric
equalizers and of narrow-band notch filters. With its excellent audio quality and outstanding specifications it is
simply better than any conventional equalizer. The ULTRA-Q can be used to make up for frequency response
deficiencies and to creatively process any audio material, thus giving you undreamed-of equalization flexibility.
It is a highly efficient and all-purpose tool both in creative audio processing in broadcast and television studios,
in video post-production and on stage. Each of its four bands can be freely adjusted in quality: from extremely
narrow to broad-band. The TUBE ULTRA-Q is superior to graphic equalizers in all respects.
The BEHRINGER TUBE ULTRA-Q uses our newly developed ULTRA-TUBE technology, a development
resulting from two years of intensive research work by our engineering team. The ULTRA-TUBE technology
overcomes the problems related to tube circuitry (see chapter 4) and generates upper harmonics even at low
levels to give your recordings more warmth and power.
2.2 The TUBE
ULTRA-Q in the signal path
The best point to insert the TUBE ULTRA-Q in the signal path depends on the task on hand: basically, it can
be inserted in the main mix insert points of your mixing console, subgroup inserts, subgroup outputs, effects
paths or between signal processor(s) and mixing console/power amp, etc.
Due to its 2-channel architecture, you can also insert the TUBE ULTRA-Q in two independent channels of the
mixing console (if available). This way the TUBE ULTRA-Q acts as a high-quality and versatile channel EQ.
Depending on the wiring of the inserts on the console, you either need a special 1/4" stereo insert cable that is
routed to two mono jacks (send & return), or two separate cables for the send and return path. Connect the
insert sends of the subgroups to the inputs on the TUBE ULTRA-Q, and the insert returns to the outputs.
You can even connect the two channels of the TUBE ULTRA-Q in series to make one equalizer with 8 bands!
Connect the output of channel one with the input of channel two. Set the output of channel one as well as the
INPUT control of channel two at 0 dB.
2.3 Filter settings
You may find that getting to know a dual channel processor like the TUBE ULTRA-Q is easier when you
concentrate on one channel first. If you have a mixer, connect the TUBE ULTRA-Q to the insert of one channel
only.
Always start off by setting all controls to neutral. All gain controls at 0 dB and bandwidth wide. This prevents
wasted time looking for non-existent problems or that settings with a gain higher than 0 dB cause problems
