Info
In the digital age achieving a higher level of quality is something that is nearly impossible to do with just higher sampling rates or bit depths. Digital processing quality is better than ever, and has reached a level (with the new DVD standard) that meets even the highest sonic and dynamic requirements. With a sampling rate of 96 kHz we can reproduce frequencies that are more than double the highest frequencies man's hearing mechanism is capable of perceiving. A resolution of 24 bits offers us a dynamic range that can capture sound at pressure levels that go far beyond the threshold of pain of human hearing. In the past, our attempt to reproduce all the perceptible nuances of a sound was severely limited by the available technology; today we are much closer to capturing all the details of a sound in its full glory.
Question
Since digital technology today is capable of such high resolution, one would think that the best and shortest connection would be a pure analog-to- digital converter. So why is MindPrint now developing high-end analog technology?
Answer
Even more important than the quality of the digital converter itself is the quality of the analog circuitry preceding the converter. Today the only part of the signal chain that is subject to loss is the analog section that prepares the signal right before it hits the digital realm. The task of the DTC™ is to make this part of the path as good and as short as possible. The thing to keep in mind is that the sound of instruments and microphones occur in the analog realm, as waves and current, and not as bits and samples. And waves and current are very sensitive as to how they react to physical quantities such as impedance, capacitance, and induction. And only when we pay proper attention to these quantities, and waves and current are turned into the "right form," do we stand a good chance of performing a proper conversion to digital. Technically speaking, the job of the DTC™ is to take a very weak modulating eleHigh-Zensitivity™ Transformer. The complex interplay of impedance, capacitance and induction in the input transformer is responsible for the optimal matching of the microphone's diaphragm to its electronics, and aids considerably in enabling the microphone to reproduce sound in a natural manner. MindPrint has researched these phenomena and collaborated with the company Hauffe to develop
a new transformer.
This sophisticated transformer possesses the advantageous sound characteristics known from older models, but avoids their common side effects, such as phase distortion in the treble region. It can do so because it has such an extremely broad frequency range (up to 127 kHz) that the phase distortion occurs out of the range of human hearing. Furthermore, because it has a turns ratio of 1:5 the transformer makes life easier for the subsequent amplifier stage, thereby reduces distortion and makes it possible to achieve an extremely good signal-to- noise ratio.

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. |
|
|
1.1 Microphone input |
|
|
Connections: |
|
|
An XLR jack is provided on the back of the DTC™ |
|
MIC IN A |
for each channel for microphones of all types. |
|
To accommodate condenser microphones, |
||
BALANCED |
48-volt phantom power can be applied from |
|
a switch on the front panel. |
||
|
||
|
Impedance is 5 kOhms. |
|
|
Operation: |
|
|
MIC IN: switches on the microphone input. This |
|
|
switch has priority over all other input switches. |
|
|
MIC GAIN: adjusts the input sensitivity of the |
|
|
microphone signal within a range of +20 dB to |
|
|
+72 dB. |
|
|
-20 db: switches a passive pad of -20 dB before |
|
|
the microphone channel preamp stage to avoid |
|
|
distortion from high-output microphones. |
|
|
48 V: applies phantom power to the channel. |
Warning: DO NOT turn on the 48V phantom power with unbalanced microphones or ribbon mics,
as these can be damaged by the phantom power!
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?
Answer: The impedance of microphones is not a constant but is frequency dependent. Within the frequency range of microphones there exist certain impedance peaks which can far exceed 1000 Ohms. If the input impedance of a microphone preamp is less, these peaks are damped, which in effect automatically changes the frequency response. Since these peaks occur especially in the treble region, the automatic damping of low-impedance preamps leads to a loss of brilliance. The DTC™, due to its highimpedance design, can handle even extreme peaks and thereby avoids losses in the highs. This especially makes dynamic microphones sound more transparent and natural. Condenser microphones also sound better, since their amplifiers, which are not loaded down as much, can operate with less distortion. ctrical signal with a very broad frequency range and amplify it and "shape" it. But this electrical signal has its own peculiarities: depending on whether the induction and the capacitance is set up in the circuit to run in parallel or in series, these can have a damping effect on the bass and treble. With all analog sound sources, whether pickup or microphone, or even a normal cable, the capacitance and inductance play a role and influence the sound. The special input circuitry of the DTC™ respects them in a very special way, so that they do have the necessary "raw form" required for the subsequent frequency and dynamics processing.

1.2 Line Input |
|
|
Connections: |
|
LINE IN A |
On the rear panel, the DTC™ includes a SEND |
|
and RETURN jack on each channel for inserting |
||
BALANCED |
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). The Sleeve is |
|
|
connected to ground. When you insert an |
|
|
unbalanced mono 1/4-inch plug, the RETURN |
|
|
automatically switches to unbalanced |
|
|
operating mode. |
|
|
Operation: |
|
|
LINE/INSTR GAIN: adjusts the preamplification |
|
|
level of LINE IN, INSTRUMENT IN, |
|
|
and DIGITAL IN. |
Note: Ensure that the MIC IN button is not pressed in.
1.3 Instrument Input
Connections:
A 1/4-inch mono input jack for connecting instruments is located on the front panel of the unit. When you insert a plug into this jack, the Line input and the Digital input are automatically switched off. The sensitivity of the Instrument input was chosen so that electric guitars and bass guitars could be connected directly.
Operation:
LINE/INSTR GAIN: adjusts the preamplification level of LINE IN, INSTRUMENT IN,
and DIGITAL IN.
INSTRUMENT IN: becomes active the moment you insert a plug into this jack, assuming that the MIC IN switch is turned off.
Info
The pin-outs of the XLR jack are in accordance with to the international standard, IEC 268-12, whereby Pin 1 is ground, Pin 2 is hot (positive) and Pin 3 is cold (negative). If you are using an unbalanced connection, Pins 1 and 3 are to be bridged. If you have a stereo-style TRS plug, the tip carries the positive signal and the ring the negative, while the sleeve is connected to ground. If you insert an unbalanced mono 1/4-inch plug, the input automatically switches itself to unbalanced mode.
ENGLISH
Info
With an input impedance of 2.2 megohms, the instrument input ensures that there will be no damping of highs by magnetic pickups and no damping of the lows by piezo-electric pickups.
