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

    Some words about the differences between Niimbus US 4 / US 4+ / US 5 / US 5 Pro The audio circuitry and power supply circuitry is totally identical on all 4 items. This concerns the inputs (although US 4 offers less inputs), the line outputs, the headphone amps, the power supply. Nothing is...

    Violectric HPA V280 - balanced headphone amp - impressions and discussion thread

    Nobody must be puzzled of not receiving his ordered HPA V280 amp. We shipped our complete inventory to Drop - nothing left in stock ! As far as I know Drop scheduled the delivery somewhen in July. Would like to hear some hopefully positive opinions ... But as the successors of V281 and V280...

    Violectric HPA V280 - balanced headphone amp - impressions and discussion thread

    Ex works the unbalanced outputs from HPA V280 are set to 2 x stereo operation. But there are jumpers inside the amp to provide balanced operation for both ¼” phone jacks. Please see the attached pic from HPA V280. V280 open low res.jpg The 2 jumpers are close to the 4-pin XLR socket. "U"...

    Just take a look at the manual which can be downloaded here US 4+ Manual 2018-en-2.pdf / US_4_Manual_2018-en-2.pdf In the technical data you can find the output impedance from the headphone outputs to be 0.1 Ohm unbalanced and 0.2 Ohm balanced. Cheers, Fried

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

    As you can see from the block circuitry, Niimbus US 4+ is able to receive unbalanced signals and output balanced and unbalanced signals on its headphone- and line outputs. Same is true for the balanced inputs. All this with maximum flexibility as the headphone rails and the line-out rails may...

    Can Lake People pre amp cause a fire?

    Funny review that. I would recommend reading the manual first and than compare. So Z would have known that on G109 there are 3 different gain settings, that the figures for the output power are per channel, that provisions are made so amp will not explode. But, if you connect a very sensitive...

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

    Just chiming in to answer a few questions. Is Niimbus the V284 we talked about some time ago? Yes and no. We had plans to relase an amp over V281. As V281 turned out to be our most successful amp we analised customers demands and wishes the past years. The results - even to questions never...

    The status led is red for some seconds during powering on. Afterwards it turns white to display correct operation. Any failure caused by DC or overload will disconnect the headphones from the amp. This again is displayed by the satatus led turning red.

    Violectric HPA V281 - Vorsprung durch Balanced

    @ zhgutov (Dimitry) and the measurements. Crosstalk is always measured by every manufacturer with the volume potentiometer fully open (right or CW position). As a matter of facts and by design a potentiometer will drive the signal to high(er) impedance state – thus makes the signals more...

    Violectric HPA V281 - Vorsprung durch Balanced

    These words had been posted by me earlier but it seems to be necessary to bump them from time to time ... About different kinds of potentiometers (volume control) Think of a simple potentiometer as an open resistor with its resistance increasing from one end to the other. One end of the...

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

    One aspect for "Niimbus" is meteorological and means a special kind of cloud. We had a more general approach in mind as "Niimbus" means -> reputation and brilliance, also there is a theological aspect as "Niimbus" also stands for -> halo. But "Nimbus" in our case is not intended to describe the...
