NAT AUDIO - SPECTACULOS

Un singur cuvant defineste totul: SPECTACULOS.

O liga aparte, un Ultra High-End pur, NAT AUDIO seteaza propriile standarde.
Si efectele sunt imediate.
Impactul vizual este imediat completat de cel sonic, emotional.

Reprezentatia este live, in fata ta, in casa ta.

Totul pana la cele mai mici detalii, pana la cele mai profunde trairi pe care ti le poate
crea un concert live, in confortul casei tale.

Smoothness, life like, deeply musical sound.

SPECTACULOS.

Single Ended Integrated Amplifier
After a few years in production NAT revised a real high-end integrated amplifier -
from Single to Single HPS (Hybrid Power Supply)!
Single HPS operates in single-ended, zero global feedback, pure class A manner.
Power output is set to 50W into 8 ohms.
Best quality of amplification will be with moderate sensitivity loudspeaker with stable
impedance from 4 ohms to 16 ohms.
Driver stage in Single HPS form E88CC (or equivalent) tube, capable to act as low
distortion stage, made by military standard, indicate as N.O.S. (new old stock) grade
of the highest quality.
Output stage form military grade direct heated triode (D.H.T.) GM70, high performance
tube capable to dissipate up to 125W.
Single HPS represent a truly single-ended design without parallel connection of tubes
with high 50W of power output.
Hand coiled and assembled wide bandwidth output transformer (custom designed for NAT ) is used.
Single HP's bandwidth from 10Hz - 60.000Hz has exceptional good flatness for single-ended
zero feedback type.
By specific connection of the output transformer with power tube, amplifier may drive almost
any type of loudspeaker with damping factor that is few times higher than normal.
Filament soft start improve reliability of entire integrated amplifier by avoiding voltage stress
during turn-on procedure.
Standby function additionally improve reliability of non analog section.
No any adjustment from time to time of output tubes is necessary.
Single HPS has automatically adjust current capability for GM70 tube no matter of tube duration -
constant current in time domain - from the brand new to the end point of tube lifespan.
To avoid unnecessary heat Single HPS has possibility to be selected to low mode - 30W of output
power with significantly reducing of power consumption!
Power supply section participate in sound quality almost as amplifiers main circuit.
Silent power unit of 400W is designed for double power than Single HPS consume.
Over 500J of energy storage is used in form of high quality multi-capacitors bank!
Separate power supply (conditioner) unit additionally improve sound quality by removing magnetic
leakage flux inside the main chassis!
For the highest "purity" of power supply voltage a special designed and selected passive components are used.
Tonal quality is totally independent from line voltage instability.
Attenuation network as one of the most important part of any integrated amplifier is realized in Single HPS
as 56 high reliability silver contact silent relays network.
Only one resistor of high quality at any volume setting is on the signal path (shunt type)!
Volume control linearity is at high level - from DC to over 1MHz!
Single HPS is equipped with multi function remote control unit made from solid block of aluminium.
Front panel is made from solid block of aluminium as well! Indication of all amplifiers function is shown
by blue led's on universal function display.
Quality of electronic components that is used inside Single HPS are at high level - military grade and N.O.S. tubes,
Teflon and "in-oil" military grade capacitors, Caddock and Vishay 5ppm resistor, Ohmite Alumina HV type resistor,
many electrolytic capacitors for 105C of operating temperature, last generation J-FET semiconductors, laboratory
grade speaker connectors, Hammond mechanics, teflon isolated silver-ofc military grade wiring.
Single HPS works properly at world wide AC line voltage from 100 – 250 VAC, 50-60Hz (different voltages set in factory only).
ADDITIONAL INFO:
Single HPS is equipped with pre. out connection for subwoofer amp. or similar biamplification purposes.
There is possibility for connecton of external preamplifier (line stage) to drive Single HPS as stereo power amplifier.
NOTE:
Standard version use pseudo-balanced input
First step of upgrade: pure-balanced input realised with hand coiled nano-crystalline core transformer
Premium step of upgrade: pure-balanced input realised with hand coiled silver-ofc wired nano-crystalline core transformer
