BPS
Solid State Batery
Phono Stage

Umanjena veličina Nagra BPS (BPS - Bipolar Phono Stage) fono sekcije je rezultat upotrebe bipolarnih tranzistorsa, sa povoljnijom cenom za implementaciju u odnosu na verziju sa cevima.
The reduced size of the Nagra BPS phono preamplifier is the immediate result of using completely solid-state technology, less costly to implement than for the valve version.

The Nagra BPS enjoys an attractive positioning thanks to a simplified approach as regards functions. Nagra however retained the popular load adaptation found on the VPS model, which allows to obtain, with small plug-in modules, the desired matching between the phono preamp and the specific cartridge used on the turntable arm.
The equipment supports either moving-coils (MC) or moving-magnet cartridges (MM) by means of appropriate switching.

VFS - Vibration Free Suport
Za idealnu reprodukciju VPS bi trebalo da se instalira na VFS (postolje za absorpciju vibracija) za totalnu eliminaciju mehaničkih vibracija.
Ideally, the VPS should be installed on the VFS (Vibration Free Suport) shock absorbing plates, to totally eliminate any mechianical vibration from being transmitted to the highly sensitive input stage.

PL-P

Battery operated Tube Pre Amplifier with phono stage

PL-P je visoko kvalitetno cevno predpojačalo u klasi A sa visoko preciznom Phono sekcijom za gramofonske ploče. Sa jedinstvenim internim dopunljivim baterijskim napajanjem, visoko osetljivom Phono sekcijom i u potpunosti izolovanim strujnim napajanjem kako bi se izbegao bilo kakav šum.
The PL-P vacuum tube pre-amplifier is a high quality pure class A tube based pre-amplifier including a high precision phono stage for vinyl records. With its unique internal rechargeable battery power supply, the highly sensitive phono stage, features individually hand-wound NAGRA built transformers, is entirely isolated from the mains power supply and hence avoids any form of hum loop. Able to handle both moving coil and moving magnet cartridges and up to 4 independent sources the PL-P is an extremely flexible preamplifier.
Uncompromised power supply
In any pre-amplifier, the power supply is a sensitive and significant component. This is especially true when dealing with phono levels. That’s why the PL-P power supply uses a set of rechargeable "D" cell batteries, operating through an external current charging AC supply. This design eliminates all disruptive effects of AC powering from wall outlets and may solve persistent hum problems. The internal power supply regulation circuitry of the PL-P uses proprietary, dual DC-to-DC converters to eliminate power supply ripples and assures a clean power source for all active electronic stages and components.
Unique design phono stage
The phono stage is built around the best tubes out of our selection and especially designed Nagra transformers for impressive noise figures, dynamic and high-resolution performance with both moving magnet and moving-coil cartridges.
Variable capacitive (from 47 pF to 837 pF) and resistive (30 Ω to 330 Ω) loading is provided to allow ideal matching with most available cartridges. Switches for selecting the appropriate loading options are internally mounted on the circuit board to protect sensitive low-level signals from undesirable interferences.
A class tube
Two triode sections, biased for pure class-A operation, are implemented in each channel for additional amplification. The PL-P has two stages, the first one for level input management and the second for output level management and record loop.
As in all vacuum tube circuits within the PL-P, precise DC filament voltage regulation from the power supply ensures low-noise, high-resolution performance and a long lifetime. The output stage vacuum tubes, operating in pure class-A, are directly coupled to the output connectors; they can accommodate loads as low as 600 Ω. To facilitate tape transcriptions and external signal processing, a full tape loop facility is also provided.

Attention to detail
To reduce unwanted interference, the main circuit board is mounted on elastomer dampers to eliminate the effect of external vibrations.
To conserve component life and battery reserve, only those vacuum tubes required for the selected input are turned on. The audio output is automatically muted when switching between input sources.

Ergonomics
Input selection is made on the left side of the front panel using a precision rotary switch. One phono and three line level inputs are provided. Input levels for all sources can be adjusted via left and right potentiometers on the front panel. A clever geared clutch mechanism, allows these channel adjustments to be made either independently or together.

Tradition - Level matching through the Nagra modulometer
A highly precise, Nagra-made modulometer, identical to the legendary NAGRA IV-S, provides a multitude of functions through two coaxial, internal pointers representing the left and right channels. The Nagra modulometer is a true measurement device that allows precision over a large scale. The modulometer can be used to adjust the volume and balance potentiometers for:

• Reaching a proper balance between left and right channels ; 
• Compensating the level differences between various recordings ;
• Controlling the power supply DC input level ;
• Controlling the output level of the amplifier (if correctly sets)

PSA

Pyramid Stereo
Power Amplifier

PSA je stereo verzija PMA postavljena na jednoj šasiji piramide. Daje 100 W izlazne snage po jednom kanalu. Pruža istu čistoću zvuka i prirodnu transparenciju kao i MPA ali u mnogo kompaktnijem formatu.
The PSA is a stereo version of the PMA mounted in a single pyramid chassis. It gives 100W of output power from a single stereo unit. The PSA provides the same sonic purity and natural transparency as the MPA but in a more compact format.  Designed to be used in conjunction with either the PL-L or PL-P pre-amplifiers and is an efficient amplifier with a unique power factor correction system with auto start stop.
Unique design
The PSA is a single chassis unit, delivering 100 W (into 8Ω). The revolutionary concept encompasses an aluminium pyramidal design that is as functional as it is distinctive. The electronics benefit from the experience of the MPA, Nagra’s first solid-state power amplifier.
Pure power = pure sound
The performance of an amplifier depends very much on the powering unit, thus on the mains’ quality. As the latter can’t really be improved, the PSA integrates a PFC – Power Factor Corrector. This device acts like a reserve of power to deliver pure DC voltages to the amplifier. Benefiting from Nagra’s first PFC developed for the MPA, the pyramid’s innovative PFC is the subject of a new Nagra patent.

Audiophile’s choices
To achieve ultimate sound and reliability, the selection of every component is critical. This is especially true for the choice of the power transistors. After numerous electrical and subjective tests, the Research and Development team has chosen to use MOSFET transistors from Exicon. They demonstrated the best characteristics among all the specifications we are concerned with.
Controlling power
When dealing with top-class loudspeakers, you are entitled to expect the best protection from your amplifier. The PMA will automatically switch to the protection mode in the event of a DC voltage occurring on the output connectors or in the case of overheating. In addition, an overload LED will blink if the PSA reaches its maximum power.

VPA

Pure Class APush-Pull

Triode Monoblocks

VPA je par mono cevnih pojačala. Opremljeni su sa simetričnim i asimetričnim ulazima, pružaju snagu od 50W u čistoj klasi A bez povratne sprege. Koriste par uparenih i ručno selektiranih 845 cevi ya yvuk bey premca. Još od prestavljanja 1998 godine, VPA su postavili novi standard za cevna pojačala, osvojili prestižne nagrade i što je još važnije postali referenca za ogroman broj audiofila širom sveta.
The VPA is a pair of mono block vacuum tube power amplifiers. Equipped with symmetrical and asymmetrical inputs, they offer a power output of 50 Watts through a pure class A output stage with no feedback. Using a pair of matched and individually selected 845 output tubes the VPA offers a clarity of sound second-to-none.  Since its introduction in 1998, the VPA has set new standard for vacuum tube amplifiers, won prestigious awards and, more importantly, became a reference for a tremendous number of audiophiles all over the world.

Difficult Speaker Loads and Zero Negative feedback
Vacuum tube amplifiers seldom drive difficult speaker loads with success. Using electrostatic or low-impedance dynamic speaker designs with these amplifiers often yield unpredictable results. With the VPA, implementing a zero negative feedback design renders matching difficult speakers much easier. In addition, the VPA offers 4, 8 and 16 Ω outputs so it can accommodate even the most demanding loudspeakers.Constructed in machined-aluminum towers, its highly sophisticated design is based on Nagra’s simple rule: only the best components, no compromises on quality. In addition, the VPA uses fully balanced circuitry from input to output to minimize intermodulation distortion and phase shift as well as decreasing the need for internal feedback.
As a result, the rise time, slew rate and overshoot characteristics of the Nagra VPA are uncommonly good compared to other amplifiers, and simply extraordinary for one based on vacuum tubes. These performance characteristics are constant whether the VPA is delivering minimum or full power.

Fast, Deep and Low with Nagra Output Transformers
Proprietary Nagra output transformers are used to avoid low-frequency saturation and high frequency ringing so common in other transformer-coupled output states. Bass notes are delivered with absolute authority and sound-stage scale delineation is simply superb.

Choice of 845 Tubes
The 845 tubes go through a 24 hour burning and numerous measurements before computer-assisted matching by pairs.
Inputs
The VPA features both balanced and unbalanced inputs on XLR and RCA connectors.
Monoblock design
The monoblock design offers the advantage of providing one power unit per channel, this contributes to the channel separation and thus respects the signal’s integrity. The amplifiers should now stand close to your loudspeakers, enabling shorter speaker cables to be employed and thus allows a better damping factor.
In addition, the tower configuration allows an optimization of the floor space.

About the company - Nagra, a legendary brand, an unique company
Few names in the world of professional audio enjoy prestige on a par with that of Nagra.
Spanning more than half a century, the story of the brand has been punctuated with inventions and developments that have revolutionized the history of sound recording.
In 1951, Stefan Kudelski developed the first independent, portable recorder, the
Nagra I. This machine went down in history as it introduced a concept that had remained unattainable until that moment: freedom of movement.
For the world of radio and television and for the cinema and recording industry in particular, this was a giant step forward, and one that opened up extraordinary horizons. The invention was all the more spectacular in that it came with a very high quality of sound reproduction. In this regard, Nagra recorders surpassed many large stationary installations. Furthermore, they were exceptionally robust.
Different generations of equipment succeeded one another, continuously developing the qualities upon which the brand’s success had been built. Nor was this triumph limited to the ranks of reporters and sound engineers.
Scientists, explorers, ethnologists, musicologists and other enthusiastic sound recordists traveled to the remotest corners of the planet, their Nagra machines slung across their shoulders, collecting records that were often of exceptional value.More than any other machine, the Nagra recorder contributed to the establishment of the world’s sound archives.
A successful overture to the audiophile market
Nagra has always fascinated audiophiles. Since 1997, the business has devoted particular attention to this market, designing a specific range of exceptionally high quality Hi-Fi equipment: PL-L and PL-P pre-amplifiers, VPA tube amplifiers and MPA, PMA and PSA transistor amplifiers, DAC converters and the SNST-R miniature recorder.These devices are achieving international success and are regarded by the specialist press as flagship equipments.
