    Violectric DHA V380 DAC/Amp/Pre-amp

    There is no LED indicator in the volume knobs from any Violectric model. This (unfortunately very expensive) feature is reserved for our Niimbus line. Concerning the volume knob from V340/V380 it was initially intended to use the volume knob from V281 (without white mark). So are the official...

    Violectric HPA V281 - Vorsprung durch Balanced

    ... it maybe your source, it may be your headphones, it maybe your cables, it maybe your ears. But chances are very low that it is the amp. Anyway, that is the reason for the balance control.

    Niimbus Ultimate Series US4/US4+/US5/US5 Pro Headphone Amps - by Lake People

    Hello Everybody. Normally I don´t answer to posts like „Why do they use cheapo Neutrik XLR sockets instead of outstanding ones from the xxx brand”. But sometime I feel I have to adjust things … Neutrik is THE supplier for high quality XLR sockets and connectors. Among others they also offer RCA...

    Review: Niimbus Audio US4+ Statement Amplifier (includes large high-end amp roundup)

    Hello everybody. The Pre-Gain setting will no have any influence on the output impedance of Niimbus US 4 (+) amps. I also often heard that people like the "sound" of a specific gain setting better than other settings - but not neccessarily 0 dB. For my opinion there is no technical reason for...

    Review: Niimbus Audio US4+ Statement Amplifier (includes large high-end amp roundup)

    @ rgs9200m Your questions: 1. OUTPUT GAIN: These switches control the level of the LINE OUTPUTS an have nothing to do with the headphone-amp section of HPA US 4+. These switches had also been part of V281, but internally. On US 4+ they are accessible from the outside. Reason:The Niimbus US 4+...

    Hello John. As I know there are some Niibus amps on their way to the US (TSAV). Unfortunately the English Manual is not fixed by now, also our new proprietary remotes are missing. We will ship both directly to the customers as soon as they are available. Thanks !

    @llamaluv About dip-switches on the back. There are tons of items in the market not offering any gain adaption via dip-switches or by other measures. So a reasonable question to all other manufacturers would be: "Why don´t you employ such on your gear." Instead you are asking the guys who offer...

    Some words about the upcoming D/A converters under the Niimbus brand. The cases will be as those from HPA US 4 /4+. There will also be the prominent large illuminated volume knob. A big point we thought about was to implement a display or not. If yes, it would have been a black/white OLED...

    No problem, as I can see you are from Germany. Just come by to have a listen. Konstanz is a nice place to be - although far from any other place in Germany. From October on there should be some dealers having the Niimbus line. Cheers, Fried

    Violectric HPA V281 - Vorsprung durch Balanced

    @ 111MilesToGo ... and others who like to know what class our amps work, if it is A - A/B - B. Most SS amps work in class-A/B as this is a good measure to avoid zero-crossing distortions compared to class-B. In former times, when electronics had been not so good, class-A was "invented" to avoid...

    Violectric HPA V281 - Vorsprung durch Balanced

    Indeed ! The problem is about having identical 4 channels which is hard to do with 1% tolerance resistors and 5% tolerance caps. Also the signal tracing will be hard ... 1. left channel in-phase / 2. left channel out-of-phase / 3. right channel in-phase / 4. right channel out-of-phase = 4...

    Violectric HPA V281 - Vorsprung durch Balanced

    Again some words about unbalanced and balanced signal. In general it can be said that balanced signals are the better signals. This is because of their nature. Feeding unbalanced signals from one item to the other means that an electric signal is pushed from the transmitter to the receiver. But...

    The leds for "headphone out" and "line out" show white light for engaged operation, red light for disengaged operation (mute). The switching between pre/post fader is made by software menu - like in V281. Via software also a dimming is possible.

    Violectric HPA V281 - Vorsprung durch Balanced

    Normally the balance control is a potentiometer between the left and right channel. Most time it features a so called tap, a forth contact on the 50 % position. As the potentiometer is between the channels it will harm the crosstalk. This in mind we found another way to have a function similar...
