TUBE ULTRAFEX T1954

Remember, less is more. Used with care an exciter can greatly improve the intelligibility while extreme set-

tings can become sharp after a while.

+

When exposed to high sound pressure level (as in a recording studio) the ears can show signs

of fatigue, resulting in a decreased sensitivity to high frequencies. Take regular breaks when

you are using this, or any other sound equipment.

2.7 Adjustment of the Tube Stage

With the settings you have achieved so far a considerable sound improvement can be made. You may not

know this, but you have already benefitted from the tube stage of the TUBE ULTRAFEX. Even when the

WARMTH control is turned fully counter-clockwise, subtle and hardly noticably warmth and musicality is

added to the signal. You can now drastically increase the effect by turning up the WARMTH control.
Increasing amounts of upper harmonics generated by the new UTC circuitry are then added to the signal. This

leads to more musical and transparent hights which combine perfectly with the enhancer/exciter effect, which

can perhaps even be reduced a little in favour of the warm tube sound. You can monitor the amount of warmth

that is added with a glance at the WARMTH meter.

2.8 Adjustment of the Surround Processor

Sound quality during signal transmission is given top priority today. The signal is processed with the help of

reverb devices, compressors, exciters, denoisers etc. to produce a compact, low-noise and transparent sound.
However, the fact that hearing impression depends largely upon the positioning of the instruments within the

stereo panorama is often enough neglected. Using the Surround Processor of the TUBE ULTRAFEX, the

intensity of the stereo effect can be dramatically improved. The program material gains in liveliness, loudness

and transparency. As in a cinema with its special acoustics, the listener has the impression that the orchestral

instruments are placed all around him. The Surround Processor enlarges the stereo basis dependent on the

program material, without audibly colouring the sonic image.
The function of the Surround Processor is based on the derivation of a special signal, which is generated from

the difference of the left an right channel. This signal is then delayed program-dependently and mixed with the

original signal. The difference between the two channels is the “stereo substance” whose ambience and spatial

information is improved by delaying the signal.
Due to the described function, the Surround Processor is principally useful only with stereo program material.

3. APPLICATIONS

3.1 Sound Enhancement during Replay

For this application, the BEHRINGER TUBE ULTRAFEX follows the master or multi-track recorder, i.e., in-

serted between tape machine and mixer (or amplifier). Of course, a cassette recorder, or similar, can also be

used as signal source.
If a companding noise reduction system is used in this situation, it should precede the TUBE ULTRAFEX.

3.2 Sound Enhancement during Recording

The sound enhancing effect can be increased by using the BEHRINGER TUBE ULTRAFEX not only during

replay but during recording. This method of sound processing is recommended, in particular, if the subsequent

storage medium is of poor quality. When doing tape duplications, the enhancer signal added during the record-

ing will compensate for the loss in quality which occurs when several generations of copies are made from the

master tape.
In this scenario, insert the TUBE ULTRAFEX directly after the master output of the mixer into the recording

path of the master or multi-track machine.
In particularly difficult cases, we recommend using the TUBE ULTRAFEX both during recording and replay.
