6 UL TRA TWIN GX212 1. INTRODUCTION Thank you very much for expressing your confidence in BEHRINGER products by purchasing the ULTRATWIN GX212. With the ULTRATWIN, you have acquired a modern guitar workstation that sets new standards in guitar amp engineering. When developing the GX212, our top objective was to reproduce the authentic sound of clas[...]

7 UL TRA TWIN GX212 1. 1 Design concept The philosophy behind BEHRINGER products guarantees a no-compromise circuit design and employs the best choice of components. The operational amplifiers used in the ULTRATWIN are exceptional: they boast extreme linearity and very low distortion characteristics. To complement this design, the choice of compone[...]

8 UL TRA TWIN GX212 The mains connection of the ULTRATWIN is made by using the enclosed mains cable and a standard IEC receptacle. It meets all of the international safety certification requirements. + Please make sure that all units have a proper ground connection. For your own safety, never remove or disable the ground conductor of the unit or of[...]

9 UL TRA TWIN GX212 8 The MID BOOST button allows you to raise the midrange frequencies in the OVERDRIVE channel. When the button is on, the associated control LED lights up. 9 Use the MORPHING control to crossfade between the various distortion characteristics available. 10 The PRESENCE control allows you to boost/cut the high midrange frequencies[...]

10 UL TRA TWIN GX212 numbers will be stored with the channels and can be recalled using the footswitch or the front panel buttons. When MIDI is on, this assignment feature will be disabled, so that in this mode both channels and effects can be selected separately. 19 The DOWN button allows you to decrement the program number. 20 With the UP button [...]

11 UL TRA TWIN GX212 32 The connectors EXT. LEFT and EXT. RIGHT allow for connecting external loudspeakers. Please always connect speakers with a minimum resistance of 4 W . Maximum power will be delivered if 8 W speakers are connected. Push down the INTERNAL OFF button (see ) to operate external speakers. 33 Use the INTERNAL OFF switch to mute the[...]

12 UL TRA TWIN GX212 2. WIRING EXAMPLES 2. 1 Standard setup consisting of guitar, footswitch and external effects device To use your ULTRATWIN for rehearsals or on stage, please wire up the unit as shown in fig. 2.1. Of course, you can also use a wah-wah or other pedal effect instead of the external 19" effects unit, or simply work with the in[...]

14 UL TRA TWIN GX212 3. EFFECTS PROCESSOR A very special feature of your ULTRATWIN is its built-in effects processor, which offers the same audio quality and algorithms as our popular 19" effects devices VIRTUALIZER PRO and MODULIZER PRO. This effects module provides 31 different groups of first-class effects such as reverb, chorus, flanger, d[...]

16 UL TRA TWIN GX212 1 7 - 19 Wah/Delay/Distortion: In general, filters are used to provide some static equalization of a signals frequency response. The wah effect  combined with delay and distortion in this preset  allows the mid- range frequencies to pass, while it more or less suppresses the remaining frequency ranges. Guitarists such [...]

17 UL TRA TWIN GX212 The LFO speed of all modulation effects is controlled by the PARAMETER control. EFFECT A controls the effect intensity or depth. High values produce a very intensive effect. In the case of the tremolo algorithm, EFFECT A adjusts the panning between left and right, and vice versa. 3 0 - 33 Phaser: From a technical point of view,[...]

EFFECT A governs the basic character of the effect in 32 steps, PARAMETER adjusts the delay time, and EFFECT B controls the delay mix. As a little extra, this effect includes an LFO-controlled notch filter, which is added as of Variation #24. P[...]

21 UL TRA TWIN GX212 7 5 - 81 Pitch Shifter: This effect shifts the pitch of the input signal and can be used to produce musical intervals and harmonies or simply to widen a single voice. Heavy detuning by several semi-tones up creates a Mickey-Mouse-type effect. The preset variations include various fixed intervals for the right channel, while the[...]

22 UL TRA TWIN GX212 9 0- 91 Compressor: Often, the signal level exceeds the headroom of signal-processing devices and therefore needs to be limited in its dynamic range, so as to avoid distortion. This job is done by compressors and/ or limiters. Limiters abruptly limit the signal above a specific threshold, while compressors provide for a soft[...]

Various degrees of resonance emphasis allow you to emulate different speaker characteristics. The PARAMETER control adjusts the cutoff frequency of the low-pass filter. EF[...]

24 UL TRA TWIN GX212 Additionally, you can deactivate the LFO in LFO-controlled modulation effects, and modulate these effects with MIDI controller #15. To activate this MIDI controller, you need to set the LFO speed to zero, either on the ULTRATWIN or by means of the corresponding MIDI controller. Of course, you can also control the ULTRATWIN from[...]
