6 TUBE COMPOSER T1952 1. INTRODUCTION In purchasing the new TUBECOMPOSER T1952, you have acquired an extremely efficient and universal dynamics processor, which combines the precision of the solid state technology with the warmth and liveliness of tube technology.
7 TUBE COMPOSER T1952 expander/gate section can be used as an independent unit to eradicate noise offering almost limitless possibilities within this application.
8 TUBE COMPOSER T1952 1. 3 Control elements Fig. 1.1: Front of the TUBECOMPOSER The BEHRINGER TUBECOMPOSER has two identical channels. Each channel is equipped with 7 toggle switches, 9 rotary controls, 6 LEDs and 2 VU meters. The CH 1 MASTER switch is for stereo operation: Fig.
9 TUBE COMPOSER T1952 6 The THRESHOLD control sets the threshold point for the Compressor section. It has a range of -40 to +20dB. The Soft Knee characteristic is applied to the signal exceeding the threshold point by a maximum of 10dB. Above 10dB, the signal would experience Hard Knee compression.
10 TUBE COMPOSER T1952 Fig. 1.3: Control elements of the peak limiter and tube sections 17 The VU METER can display three levels: the actual gain reduction of the compressor, the input or the output level. Gain reduction is displayed in a range of 1 to 30dB, the input or output level is displayed in a range of -30 to +10dB.

12 TUBE COMPOSER T1952 2.1 Compression/levelling/limiting/clipping Now that the functions of the individual sections have been clearly explained, we would like to acquaint you with more terms and relationships of the dynamics process. Compression A compressor converts a large dynamic level into a restricted range.

14 TUBE COMPOSER T1952 If the controls are set correctly, the drum sounds will be dry, sharp and clearly defined. If you do not have enough mics (or TUBECOMPOSER channels!) to record ea.

17 TUBE COMPOSER T1952 2. 6 The vacuum tube of the TUBE COMPOSER Our engineering team has made it possible to enhance the traditional tube circuitry (particularly for our TUBE COMPOSER) and adapt it to meet the high sound quality and dynamics requirements of modern, pro-level audio technology.
18 TUBE COMPOSER T1952 3.1 .3 The TUBECOMPOSER in digital recording and sampling In an analog recording, too low recording levels lead to an increased noise level, whereas too high levels will cause a compressed and squashed sound. In extreme cases, it will cause distortion due to tape saturation.
19 TUBE COMPOSER T1952 as the last link in the chain preceding the power amp. Thus, you can effectively avoid damage to the midrange/ tweeter range caused by clipping of the high-energy bass signals.
20 TUBE COMPOSER T1952 3. 3 The TUBECOMPOSER as a sound effects unit In the early 1960s, musicians began looking at the recording process as a way to create new sounds.
21 TUBE COMPOSER T1952 3. 6 Side chain 3.6.1 The TUBECOMPOSER as De-Esser De-essing is a special application of frequency selective compression.
22 TUBE COMPOSER T1952 3.6.3 Suppressing instruments during recording Another function of the BEHRINGER TUBECOMPOSER allows helpful correction of previously recorded material. If, for example, an excessively loud bass drum needs to be suppressed, reduce all the equalizers frequency bands above 150Hz.

24 TUBE COMPOSER T1952 frequencies are equally affected, we term this white noise. It is fairly obvious that electronics cannot function without components. Even if special low-noise components are used, a certain degree of basic noise cannot be avoided.
25 TUBE COMPOSER T1952 Fig. 4.3: The interactive relationship between the operating level and the 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.
26 TUBE COMPOSER T1952 level of noise, hum or other ambient background hiss, which can disturb the quality of the program material. Normally these noises are inaudible if the level of the desired signal lies significantly above the level of the noise.
27 TUBE COMPOSER T1952 processing meant the beginning of a new era of recording media that provided plenty of dynamic response and allowed for loss-free copying of audio signals. As digital media were enhanced, however, many people began to miss the warmth, power and liveliness they knew from analog recordings.
28 TUBE COMPOSER T1952 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.
29 TUBE COMPOSER T1952 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.
