6 TUBE UL TRAGAIN T1953 1. INTRODUCTION With the TUBEULTRAGAIN you have purchased an extremely musical and flexible microphone preamplifier. Our ULTRAGAIN range of devices has been a hit ever since we introduced our first model some 5 years ago.
7 TUBE UL TRAGAIN T1953 therefore impair the performance of the units. The transformer-balanced outputs, commonly used in radio and TV engineering, can also be fitted retrospectively upon request. The BEHRINGER transformer OT-1 is designed to the highest exacting standards and is available as an accessory.
8 TUBE UL TRAGAIN T1953 Fig. 1.2: Control elements on the front panel 1 Use the MIC/LINE switch to toggle between MIC and LINE modes. When the switch in up position, the unit works in MIC mode (now you can activate the +48 V switch if required; in LINE mode this function is disabled).
9 TUBE UL TRAGAIN T1953 Fig. 1.3: T ube section of the TUBEUL TRAGAIN 8 Use the LEVEL control to set the signal gain at the input of the tube stage. The gain can be set from -20 to +20dB, i.e. the signal can be attenuated or amplified by 20dB.

11 TUBE UL TRAGAIN T1953 The LEVEL control The LEVEL control sets the signal gain at the input of the tube stage. Use this control to adapt the TUBE ULTRAGAIN to either home recording level (-10dBV) or professional level (+4dBu). When this level is too low the tube effect becomes less audible and the signal-to-noise ratio deteriorates.
12 TUBE UL TRAGAIN T1953 3. 2 The TUBEULTRAGAIN as a level converter Semi-professional devices in hi-fi and home recording environments are usually operated with a nominal level of -10dBV (0.316 V), while the level used in studios is 0dBu (0.

14 TUBE UL TRAGAIN T1953 without components. Even if special low-noise components are used, a certain degree of basic noise cannot be avoided. This effect is similar when replaying a tape. The non-directional magnetic particles passing the replay head can also cause uncontrolled currents and voltages.
15 TUBE UL TRAGAIN T1953 Fig. 4.3: The interactive relationship between operating level and headroom The need therefore arises for a fast acting automatic gain control system which will constantly monitor the signals and which will always adjust the gain to maximize the signal-to-noise ratio without incurring signal distortion.
16 TUBE UL TRAGAIN T1953 With the introduction of semiconductor technologies in the field of audio amplification it soon became clear that the tube would have to gi ve way to the transistor, as this device featured an enormously enhanced signal- to-noise ratio, less complex power supply and improved frequency response.
17 TUBE UL TRAGAIN T1953 Fig. 4.6: Pentode In a triode the capacitance between grid and anode is a problem with regard to high frequencies and large amplification factors. For this reason, the pentode has a positively charged screen grid between the control grid and the anode.
18 TUBE UL TRAGAIN T1953 4. 6 The best of both worlds Despite many efforts neither manufacturers nor developers have succeeded so far in simulating these positive properties of the tube by means of other devices. Additionally, the natural capabilities of the tube to act as a soft limiter can only be mimicked with highly sophisticated circuitry.

20 TUBE UL TRAGAIN T1953 To eliminate this risk, the BEHRINGER TUBEULTRAGAIN automatically disables the unbalanced jack in MIC mode. Microphones can thus only be connected to the XLR connector. Never switch on the +48 V supply when you use unbalanced microphones, as this could cause electrical damage.
21 TUBE UL TRAGAIN T1953 5. 3 Audio connections As standard, the BEHRINGER TUBEULTRAGAIN is installed with electronically servo-balanced inputs and outputs. This circuit design features automatic hum and noise reduction for balanced signals and thus allows for trouble-free operation, even at high operating levels.
