Page 6: Introduction
The heart of the TUBE ULTRAGAIN is an extremely low-noise microphone preamp circuit that uses discrete components to produce a highly transparent sound. In combination with our BEHRINGER tube technology, the operational amplifiers 4580 and a sophisticated circuit topology, the TUBE ULTRAGAIN yields excellent noise and distortion properties! The switchable +48 V phantom power supply allows for connecting almost any kind of microphone and suppresses power-up thumps with its “soft mute”... -

Shipping claims must be made by the consignee. The BEHRINGER TUBE ULTRAGAIN fits into two standard 19" rack units of space (3 1/2" / 89.5 mm). Please allow at least an additional 4" depth for the connectors on the back panel. - Page 8 TUBE ULTRAGAIN T1953 Fig. 1.2: Control elements on the front panel 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).
- Page 9 TUBE ULTRAGAIN T1953 Fig. 1.3: Tube section of the TUBE ULTRAGAIN Use the LEVEL control to set the signal gain at the input of the tube stage. The gain can be set from -20 to +20 dB, i.e. the signal can be attenuated or amplified by 20 dB. When the control is at its center position, the level is unaltered.

The nominal level is +4 dBu. The maximum output level is +16 dBu. 2. OPERATION Before you can use the BEHRINGER TUBE ULTRAGAIN as a preamp, we recommend that you study the various functions of the device. The high gain factors provided by the microphone preamp can produce extreme levels on the output side, which may damage subsequent devices. -

A/B comparison. The WARMTH control The UTC circuitry forms an integral part of the BEHRINGER TUBE ULTRAGAIN. It provides the distinct tube sound. Gently turn the control clockwise to add increasing amounts of harmonics. It improves the transparency of other instruments, particularly those rich in upper harmonics. The WARMTH meters provide an instant overview of the process. -

Yet, the increase in loudness goes in line with a need for optimized audio quality. Today, audiences expect to hear a powerful and transparent sound. To fully understand how the BEHRINGER TUBE ULTRAGAIN works you will need to know the meaning of a decibel and how audio dynamics work. -

TUBE ULTRAGAIN 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. The resulting sound of the various frequencies is heard as noise. -

TUBE ULTRAGAIN 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. -
Page 16: Design And Functional Principle Of Tubes
TUBE ULTRAGAIN T1953 With the introduction of semiconductor technologies in the field of audio amplification it soon became clear that the tube would have to give way to the transistor, as this device featured an enormously enhanced signal- to-noise ratio, less complex power supply and improved frequency response. Plus, semiconductor-based circuits can be realized much more easily—for less money. -

TUBE ULTRAGAIN 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. -

TUBE ULTRAGAIN 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. -

TUBE ULTRAGAIN T1953 Fig. 4.8: Dynamic range of various media 4.9 Phantom power Condenser microphones need a specific supply voltage polarizing the condenser diaphragm. This voltage can be furnished from an internal battery, or an external power supply that is either connected directly to the microphone or supplies the voltage through the microphone cable. -
