The gain control can be used to adjust the preamplification. For microphone signals, a preamplification of up to 68 dB can be realized – so even really demanding microphones can show their qualities. The control range for line signals ranges between -20 dB and +16 dB. The control range for instrument signals ranges between -6 dB and +30 dB.\r\n\r\nThe Preamp Out picks up the signal directly after the microphone amplifier. This signal can also be recorded on a separate track in the DAW, for example, to be on the safe side. If it is noticed after a recording session that the singer was a little louder in the perfect take and therefore hits the compressor too hard, this incorrect setting can still be changed afterwards. The signal recorded for safety can later be played back into the Channel One Mk3 via the Line In and be processed there with Tube Saturation, Compressor or other tools.\r\n\u003ch3 id=\"toc_1\"\u003eTUBE SATURATION – MAGICAL TUBE SOUND\u003c\/h3\u003e\r\nWith this control the amount of tube saturation can be determined. The output level is accommodated automatically, in extreme settings the level increases by only 6 dB. Therefore decent to expressive harmonic distortions can be easily dialed in by turning just one knob.\r\n\r\nSaturation effects are generated through the tube being pushed to and beyond its normal operating limits. In contrast to semiconductors, a tube thus pushed to such levels does not clip from a certain level, approaching more gradually its level limits and thereby producing its typical tonal result, which in audio signal processing can have such often profitable aural effects — on one hand (and depending on the amount applied), from subtle to extensive harmonic distortion and on the other hand, a compaction of the sonic event, that is, a limiting effect that exhibits a pleasant, rounded or soft sound. Acoustically and also in its range of applications this can be compared very well with tape saturation effects.\r\n\u003ch3 id=\"toc_2\"\u003eDE-ESSER\u003c\/h3\u003e\r\nUnobtrusively and effectively, the Auto-Dynamic De-Esser removes distracting S‑sounds, in a mix or on vocal tracks, by detecting only the S‑frequencies, mixing them back into the main signal phase-inverted, and thus simply deleting sibilants in the original signal. The Auto-Threshold control maintains constant processing even as the singer’s distance from the microphone varies. The result is tonally neutral, unobtrusive and extremely effective. Even at high S‑reduction values, the de‑essing has no significant effect on the character and timbre of the voice.\r\n\u003ch3 id=\"toc_3\"\u003eTRANSIENT DESIGNER\u003c\/h3\u003e\r\nWith the Transient Designer it is possible to manipulate the envelopes of audio signals level-independently (no threshold!). Accelerate or slow down transients, lengthen or shorten sustain times – with just two controls: attack and sustain. All time constants are automated in a musical way and optimize themselves adaptively according to the characteristics of the input signal.\r\n\u003ch3 id=\"toc_4\"\u003eCOMPRESSOR\u003c\/h3\u003e\r\nThe compressor is also extremely easy to operate with one knob only; its strength lies in its unobtrusive, musical operation. The Compression control can be used to set a threshold between 0 dB and -20 dB. The lower the threshold, the more the compressor works.\r\n\r\nThe Make-Up Gain control can be used to make up for the overall level reduction caused by compression. A value between 0 dB and 20 dB can be set by which the level is increased again after compression. With the help of the Gain Reduction display on the panel, the adjustment is very simple: if the maximum reduction value caused by the loudest part is e.g. -9 dB, the Make-Up Gain control should be set to values around +9 dB.\r\n\u003ch3 id=\"toc_5\"\u003eEQUALIZER\u003c\/h3\u003e\r\nThe center frequency of the half-parametric bass filter is set with the LMF control (low\/mid frequencies). The adjustable frequency range is between 30 Hz and 700 Hz so that this filter covers a range of about 4.5 octaves, allowing it to be used from the deepest bass to the lower mid range.\r\n\r\nThe center frequency of the semi-parametric mid\/high frequency filter is set with the MHF control. (MHF: mid\/high frequencies). The frequency range can be set between 680 Hz and 15 kHz so that this filter covers a range of 4.5 octaves and can be equally employed in the lower mid as well as the high range.\r\n\r\nThe high frequency filter in the equalizer module is described as Air. A coil-capacitor filter with so called bell characteristics and a center frequency of 19 kHz comes into operation here. At this frequency the maximum possible accentuation is +10 dB, the maximum possible damping is -10 dB. The soft and natural tonal property, characteristic of the coil-capacitor filter, lends itself extremely well to provide clarity and air to vocals in the upper frequency range thereby improving their presence. On the other hand harsh sounds can be lent a more pleasant sound characteristic through damping.\r\n\u003ch3 id=\"toc_6\"\u003ePREMIUM LUNDAHL TRANSFORMERS\u003c\/h3\u003e\r\nThe Channel One Mk3 Premium includes an input transformer for the microphone inputs and an output transformer for the output Out 1. Transformers are used as an alternative to electronic balancing stages in the inputs and outputs. Transformers can be found in many classics of audio engineering. They make the bass and fundamental tines rounder and give it a little more punch. The high and overtone range sounds a bit silkier and more present.\r\n\r\nThe 2161 input transformer, which is specially designed for microphone inputs, provides an additional gain of up to 14 dB (depending on the microphone), which must then be added to the scaling. This relieves the microphone preamplifier. Since the transformer ratio passively increases the level, no noise is added. Therefore, the input transformer is more important than the output transformer in preamplifiers.\r\n\u003ch3 id=\"toc_7\"\u003eFEATURES:\u003c\/h3\u003e\r\n\u003cul\u003e\r\n \t\u003cli\u003eDiscrete preamp section perfect for vocals or instruments\u003c\/li\u003e\r\n \t\u003cli\u003eTwo microphone inputs and one line input on rear panel, and DI instrument input on front panel\u003c\/li\u003e\r\n \t\u003cli\u003eSPL's Transient Designer for manipulating the envelopes of audio signals level-independently\u003c\/li\u003e\r\n \t\u003cli\u003ePremium Lundahl input and output transformers\u003c\/li\u003e\r\n \t\u003cli\u003e3-band equalizer section for comprehensive tone shaping\u003c\/li\u003e\r\n \t\u003cli\u003eTube saturation for expressive harmonic distortion at the trun of a knob\u003c\/li\u003e\r\n \t\u003cli\u003eCompressor\/limiter controls provide unobtrusive, musical operation\u003c\/li\u003e\r\n \t\u003cli\u003eDe-esser erases sibilants\u003c\/li\u003e\r\n \t\u003cli\u003eHeadphone monitor stage\u003c\/li\u003e\r\n \t\u003cli\u003eInsert (send\/return) for patching external effects\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"Sur Sargam","offers":[{"title":"Default Title","offer_id":52663875961129,"sku":null,"price":297060.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0682\/0750\/9801\/files\/SPL-Audio-Channel-One-MK3-Premium-1.jpg?v=1770878483","url":"https:\/\/sursargam.com\/products\/spl-audio-channel-one-mk3-premium","provider":"Sur Sargam","version":"1.0","type":"link"}
