DTC_BDA_1.1 14.01.2002 16:32 Uhr Seite 5 MindPrint-DTC TM Congratulations and thank you for choosing the MindPrint ® DTC™ in your search for superior sonic results. The MindPrint Dual Tube Channel signal processor combines two high-quality microphone preamps, equalizers and compressor/limiters in one unit, giving you all the functionality of a fully-loaded high-end channel strip.
DTC_BDA_1.1 14.01.2002 16:32 Uhr Seite 6 MindPrint-DTC TM 1. The Input Section The DTC™ has a comprehensive input section consisting of a line-level input, an instrument input and a microphone input. You can add a digital input by installing the MindPrint DI-Mod 24/96 expansion module. Inner workings of the High-Zensitivity™ Transformer Question: At 5 kOhms, the impedance of the microphone input is considerably higher than normal. Why does MindPrint deviate so greatly from the 600-Ohm standard? 1.
DTC_BDA_1.1 14.01.2002 16:32 Uhr Seite 7 MindPrint-DTC TM 1.2 Line Input BALANCED Operation: LINE/INSTR GAIN: adjusts the preamplification level of LINE IN, INSTRUMENT IN, and DIGITAL IN. ENGLISH LINE IN A Connections: On the rear panel, the DTC™ includes a SEND and RETURN jack on each channel for inserting external signal processors into the DTC™ signal path. The connectors are stereo-style balanced Tip-Ring-Sleeve jacks, with the Tip hot (positive) and the Ring cold (negative).
DTC_BDA_1.1 14.01.2002 16:32 Uhr Seite 8 MindPrint-DTC TM 1.4 Digital Input If you wish to use the DTC™ as the front end for digital mixers or hard-disk recording systems, you can install a digital interface into the expansion slot provided for this purpose on the back of the DTC™. Operation: DIGITAL IN: Assuming the optional DI-Mod 24/96 digital interface is installed, pushing this switch in will activate the digital input.
DTC_BDA_1.1 14.01.2002 16:32 Uhr Seite 9 MindPrint-DTC TM Operation: METER: Switches the display between Input and Output. IN: Displays the level of the Input signal. OUT: Displays the level of the Output signal. Note: Take care when adjusting input levels that the level remains in the green, as this will leave enough headroom for later processing stages. The Output display works like the display of a digital device; that is, if the red “OVER” LED lights up, you run serious risk of unwanted distortion.
DTC_BDA_1.1 14.01.2002 16:32 Uhr Seite 10 MindPrint-DTC TM 2. Equalization: Frequency Processing 2.1 LOW CUT and HIGH CUT Operation: LO CUT/HI CUT: activating either of these buttons will switch that filter into the signal path. FREQUENCY: sets the cut-off frequency of the filter. Helpful Hint The steep 24 dB-per-octave slope of the Lo Cut filter can help remove undesirable low-frequency sounds such as vocal pops cleanly without any degradation of the rest of the signal.
DTC_BDA_1.1 14.01.2002 16:32 Uhr Seite 11 MindPrint-DTC TM 2.2 Low and High- Shelving The term “Shelving” (shelve = to slope gradually) describes the filter slope of this equalizer. For example: with a high-shelving equalizer all the frequencies above the selected frequency are boosted evenly. For frequencies below that point, the boosting gradually declines to zero. Operation: FREQUENCY: sets the cut-off frequency of this EQ band.
DTC_BDA_1.1 14.01.2002 16:32 Uhr Seite 12 MindPrint-DTC TM 2.3 Mid-Bell-Filter The designation “bell filter” derives from the bell shape of the frequency curve. A certain frequency range is boosted or cut. The farther from the center frequency, the more mild the effect. Operation: FREQUENCY: Sets the center frequency of the band. LMF: Operating range from 47 Hz to 1600 Hz HMF: Operating range from 190 Hz to 13 kHz LMF & HMF: switches the Lo-Mid or Hi-Mid frequency band into the signal path.

DTC_BDA_1.1 14.01.2002 16:32 Uhr Seite 14 MindPrint-DTC TM 3. Compressor/ Limiter: Dynamics Processing The final stage of processing is the opto/tube-compressor/limiter. When properly adjusted, it will ensure that the signal will not be overdriven into clipping in the analog realm nor (with the DI-Mod option) the digital realm. By compressing the dynamic range of the input signal, it maintains the output signal at a higher average volume level. 3.
DTC_BDA_1.1 14.01.2002 16:32 Uhr Seite 15 MindPrint-DTC TM The Release control determines how much time should be allowed to pass, after the unit has reduced a loud signal, before it is ready to again raise a soft signal. Operation: RELEASE: The Release time can be set to anywhere from 20 milliseconds to 2 full seconds. 3.4 Filter Helpful Hint A very fast Release setting (completely counterclockwise) tends to raise the level of reverb trails and overly thicken the sound.
DTC_BDA_1.1 14.01.2002 16:33 Uhr Seite 16 MindPrint-DTC TM Question: What roles do the opto-couplers and the tubes perform in the DTC™? Pegel Answer: The opto-coupler compresses in a very unobtrusive and pleasing way. Since an opto-coupler is a passive component, it sounds substantially cleaner than an active semi-conductor circuit. The tube with its natural form of saturation reliably handles the limiter function, and is naturally responsible for the harmonic overtones. mit Adaptiv ohne Adaptiv.
DTC_BDA_1.1 14.01.2002 16:33 Uhr Seite 17 MindPrint-DTC TM 4.1 Master Level The Output control determines the output volume of the DTC™. It affects the analog output as well as the digital output, if installed. LINE OUT A UNBALANCED MONITOR BALANCED Connections: The balanced XLR output serves as a recording out for any devices connected to it such as recording devices, mixing consoles, or exterrnal converters. The unbalanced 1/4-inch output is intended to be used as an analog monitoring point.

DTC_BDA_1.1 14.01.2002 16:33 Uhr Seite 19 MindPrint-DTC TM The DI-Mod 24/96 AES/EBU Digital Interface Option The DI-Mod 24/96 AES/EBU expands the DTC™ with a digital output and input in 24-bit format with sampling rates of 44.1, 48, and 96 kHz and a dynamic range of over 113 dB. It is the logical extension of the analog DTC™, optimally converting its output signal to digital, and helping your DTC™ fit into your digital studio environment seamlessly.
