This question often reaches us. Mm systems have often a very strong level rise in the frequency range above 5 kHz. The more highly the inductance and resistance of the MM´s the more highly this rise. This is not only measurable but clearly audibly, e.g. several railways rise around 10 kHz, steep waste with approx. 20 kHz. work. Different phase shifts arise negatively from mm to mm, which cannot be corrected by Phonostufen. The most glaring difference between MM and MC-systems is, apart from the basic construction and differences in the moved mass, the phase behaviour. With MM's the phase can be shifted within the scanning field gladly up to 180 degrees. In other words e.g.: the bass range is shown with correct phase and the high clay/tone range with twisted phase. The signal rotated thus its polarity completely. The angular phase shift amounts to with MC-systems however always only few degrees or milli degrees over the complete scanning field, there is probably the reason to be searched, why MC-systems are called faster, more solvent, more transparently or more spatially. All of this is simple technical provably there it to check is to after-listen and naturally. However the circle closes here, because our Phonoverstärker is always equipped with an extended RIAA, which contributes to the fact that starting from 10kHz likewise a more correct phase position and level are reached. One is closer at the original, speaks hears a more natural and more transparent extended high clay/tone rendition.

7.- TRUE balanced with just two conductors?
Normally balanced connections have 3 conductors: positive, negative and ground.
But in the case of eg. cartriges or microphones, which are balanced sources with just 2 conductors - positive and negative. The technical term is floating balanced or balanced without ground. Yes this is TRUE balanced! The positive signal is connected to one dedicated amplifier stage and the negative signal is inverted and also connected to one dedicated amplifier stage = differential amplifier!
So what happens when they bid 2 hearts???
Wrong cables to the turntable, or power cables too close to the phono cables/ phono stage,
can cause hum/noise or radio. It is strongly recommended to use balanced cables for the XLR-input ,
the PHONO2CI is intrinsically dead quiet.
Please play around with the position of your cables and the position of the PHONO2CI,
you then will localise disturbances that may come from other hifi devices/transformers/ handy loaders /lamps/ and so on.

NEW - ASIO Drivers for iTunes 6 & 7 for Windows:

NEW - recording and highend music archivie building with the USB2DA
You can record all digital inputs and the microphone input of the USB2DA
with this free software. Via USB onto your computer:
NEW - aditional digital inputs for the USB2DA
Some USB2DA users would like to connect more digital sources as inputs available.
We recommend to connect the best sounding device at the COAX input. Unfortunately are no quality COAX switches available.
But for the TOSlink input we have a suggestion: up to 4 devices my be connected at a single TOSlink input by using a cheap
COAX to TOSlink convertor and a automatic TOSlink switch 4in1 or 2in1.
....Problems with USB-connections often resulting from old drivers.
Here is the instruction for driver-installation:
Here are the latest drivers from TexasInstruments, the manufacturer of our USB-Interface-Chips:

NEW - soon we complete an instruction for:
Realtime digital room correction for the USB2DA and computers
This will be very interesting... Please contact us when you have questions or comments.

The internal DIP-Switches have following function:
OFF = bridging is DISABLED (Capacitors are ON)
ON = bridging is ENABLED (Capacitors are OFF)

Avoiding signal losses instead of correcting them. The common way of reducing measurable distortions is overall negative feedback (NFB). At the first glimpse this method seems to solve the problem, but it works only for static test signals, not for "random" music signals. Negative feedback looks good on measurement equipment and paper, but has the well known limitations in sound quality we all got used to. As there are no common ways to test short time (transient) distortions, which occur during fast signal changes, most engineers assume they just don't exist. Prof. Matti Otala developed a way to measure Transient Intermodulation (TIM), which is only a small part of the whole story. It succeeded to proove the existence of short time distortions, which origin from NFB limitations. As a consequence the development of amplifiers without overall negative feedback but only local feedback and very low dynamic and static distortions was initiated. (There are already amplifiers without NFB on the market, but with sound influencing distortions.) Advanced-Class-A avoids degradation of sound quality instead of correcting it afterwards.
The breakthrough of Advanced-Class-A technology is: The signal transistor does neither pass through its voltage characteristic Vce nor the current characteristic Ic.
Passing the voltage characteristic is avoidable by using a floating cascode circuit. This method is known, but causes losses in efficiency and power when using traditional circuitry.
As the signal transistor in Advanced-Class-A circuit does not handle the current requested by the speaker, loss in efficiency is negligible.
Advanced-Class-A's most significant progress is splitting the handling of the loudspeaker's current request from the music signal voltage output stage! Advanced-Class-A means: The signal transistor is not loaded by any connected load, either devices, cartridges or speaker's current requests, because it has strong current handling "assistants" - thus no sound degradation effects due to the load happens. With today's common amplifiers it is easy to hear whether it sounds like an airy ballet dancer or a heavyweight bodybuilder, because the music signal has to pass the more or less "heavyweight" output transistors using NFB correction. In Advanced-Class-A technology the fast, airy and delicate signal transistor and the heavyweight current assistants work, supporting each other. However, the current assistants are not "allowed" to take part of the signal voltage. This means: The signal transistor does not pass through his current characteristic Ic. The load, speakers or small-signals, "sees" only the signal transistor, but no "current assistants". This is due to the signal transistor's very low output impedance, combined with the very high output impedance of the "current assistants". In case of some small current inaccuracy that may occur, the "current assistants" are safely "overruled" by the signal transistor. Unlike usual amplifiers the Advanced-Class-A amp sounds like unlimited power, as long as it works within the designated power range; combined with speed, dynamic and colourful elegance.
