AUDES ST 900DC. AC Power conditioner New Model.

AUDES ST 900DC AC Power conditioner.

The Audes ST-900, ST-1500 and ST-3000 power conditioners are designed to power high-end and high-fidelity AV devices. The main element of the device is a 230 VAC/115 + 115 VAC balancing ring transformer designed and developed by Audes, which isolates the equipment from the household network. Despite the significant power rating of such transformers, the construction of the power conditioner completely excludes harmful electromagnetic radiation.

Audes’ own DC blocker is installed in the ST-900 DC, ST-1500, ST-3000 and ST-5000 models. This is used to eliminate the humming noise caused by direct current components in the network. It is an in-house development that works in a sound-neutral manner and therefore does not reduce the sound gain through the power conditioner.

H Audes είναι μια εταιρεία με έδρα την Εσθονία που ξεκίνησε τις δραστηριότητες της το 1935, όταν μια ομάδα ανθρώπων, αποφάσισε να δημιουργήσει την παραγωγή ραδιοφωνικών δεκτών στην Εσθονία. Το εργοστάσιο ονομαζόταν RET (Raadio-Elektrotehnika Tehas).

Η RET (Raadio-Elektrotehnika Tehas) έλαβε άδεια από το Υπουργείο Οικονομικών. Οι ιδρυτές του εργοστασίου ήταν ο Friedrich Olbrei, ο Karl Reinmann και ο Hans Võrk. Η περιγραφή των δραστηριοτήτων της αναφέρεται ως «ανάπτυξη, παραγωγή και πωλήσεις οποιουδήποτε εξοπλισμού ραδιοφώνου, ήχου και κινηματογράφου, συσκευών και άλλων ηλεκτροτεχνικών εξαρτημάτων».

Ένα από τα “δυνατά” προϊόντα της εταιρείας είναι και το Power Conditioner ST-900.

Το ST-900 μπορεί να χρησιμοποιηθεί για εξοπλισμό ήχου και εικόνας, ενώ η ποιότητα, κυρίως του ήχου, βελτιώνεται σημαντικά ως αποτέλεσμα. Απλά συνδέετε όλες τις συσκευές στις πρίζες του Power Conditioner και οι επονομαζόμενοι πόλοι αποτελούν παρελθόν. Να σημειώσουμε ότι το ST-900 λειτουργεί χωρίς διαθέσιμη σύνδεση γείωσης!
Ο μετασχηματιστής του Audes ST-900 έχει σχεδιαστεί με τέτοιο τρόπο ώστε ο αριθμός των στροφών του πρωτεύοντος τυλίγματος να είναι μέγιστος, με αποτέλεσμα την πολύ χαμηλή κατανάλωση ισχύος πράγμα που οδηγεί στο να είναι πάντα ενεργοποιημένο το Power Conditioner.

Το Audes ST-900 έχει πολύ χαμηλή αντίσταση εξόδου συνεχούς ρεύματος και επομένως μπορεί εύκολα να προσφέρει υψηλές κορυφές ρεύματος χωρίς πτώση της δευτερεύουσας τάσης (230V). Αυτό επιτυγχάνεται επειδή η Audes έχει αναπτύξει έναν μετασχηματιστή με πολύ μεγάλο πυρήνα και λειτουργώντας τον με ελάχιστη επαγωγή, οι τρέχουσες κορυφές που μπορεί να προσφέρει το Audes ST-900 είναι πολλές φορές υψηλότερες από αυτές του δικτύου.

Ένα άλλο πρόβλημα με την τροφοδοσία του εξοπλισμού υψηλής τεχνολογίας AV, είναι η “μόλυνση” του δικτύου. Ο μετασχηματιστής Audes ST-900 έχει σχεδιαστεί για να λειτουργεί ως φίλτρο χαμηλής διέλευσης. Επειδή σχεδόν όλες οι βλάβες του ηλεκτρικού δικτύου είναι υψηλής συχνότητας, η συχνότητα διακοπής είναι 800 Hz.

Στην πρόσοψη υπάρχει ένα αμπερόμετρο και ένα βολτόμετρο, για να μπορεί κάποιος να βλέπει ανά πάσα στιγμή, πόσο ρεύμα απορροφάται απο τα μηχανήματα και σε ποια τάση.

Το Audes ST-900 αντλεί ρεύμα αιχμής, περίπου 12Α, όταν είναι ενεργοποιημένο, ενώ είναι εξοπλισμένο με προστασία υπερφόρτωσης και είναι θερμικά προστατευμένο (απενεργοποιείται ο μετασχηματιστής μόλις η θερμοκρασία του, φτάσει τους 90 ° C. Όταν η θερμοκρασία πέσει στους 75 ° C, η συσκευή επανασυνδέεται αυτόματα στο δίκτυο.

General

The Audes Power Conditioner ST-900 can be used with both sound and image equipment; the quality, especially of the sound, but also that of a beamer, for example, is greatly improved as a result. The best result is achieved by connecting the entire installation to the Power Conditioner. The Power Conditioner is designed for use with both solid state and pipe equipment.
It doesn’t matter how you plug the equipment into the sockets of the Power Conditioner! The so-called poles are therefore a thing of the past. The Power Conditioner also works without an earth connection available!
The transformer of the Audes ST-900 is designed in such a way that the number of primary turns is maximum; as a result, the power consumption of an unloaded Audes ST-900 is very low; in practice you always leave the Power Conditioner “on”. On the Ampere and Voltmeter you can read how much current is absorbed at which voltage.

Stable voltage / current supply

During highly dynamic parts of an audio track (eg Tutti Fortissimo of a full symphonic orchestra, sounds of large ethnic drums, bass parts of experimental electronic music and cinematic SFX = special effects) a (power) amplifier draws enormous current peaks from the mains. Values ​​from 50 to 100A are certainly no exception, the voltage level (230V) must remain constant under these harsh conditions, so without “dips” and moreover (theoretically) an “infinite amount of current can be supplied”.
An ordinary household socket, which is connected to a distribution board in the meter cupboard with long electrical cables, cannot supply such current levels, partly because of the relatively high output impedance. The Audes ST-900 has a very low
DC output resistance and can therefore easily deliver high current peaks without the secondary voltage (230V) dropping. This is achieved because Audes has developed a transformer with a very large core and by operating it with a minimal inductance, the current peaks that the Audes ST-900 can deliver are many times higher than those of the mains.

Mains pollution

Another problem with the power supply of high-end AV equipment is contamination of the mains. This is caused by, among other things, switches, controllers of electric motors, dimmers, switching power supplies and last but not least (nearby) solar panels!
Electrical disturbances are eliminated by the symmetrical construction of the primary and secondary winding of the Audes transformer. The secondary winding is divided into two halves and has a center tap, which is connected to the ground terminals of each CEE 7/3 socket.
The high-quality CEE 7/3 sockets are galvanically isolated from the mains.
The Audes transformer is provided with proper shielding against electromagnetic interference from outside.
The Audes ST-900’s transformer is designed to act as a low-pass filter. Because almost all electrical network failures are high frequency, the cut-off frequency is 800 Hz. The foregoing technical aspects make it possible to remove virtually all contamination that reaches the primary side of the transformer via the mains, so that a reliable stable voltage and very high-quality clean power is available for your equipment on the secondary side of the transformer.

Security

The Audes ST-900 draws a peak current of approximately 12A when switched on. As a result, the inrush current of the Power Conditioner is not too high for your 16A fused mains connection and there is no need to use a switch-on delay.
The Audes Power Conditioners are equipped with overload protection and are thermally protected, which switches off the transformer as soon as the temperature of the transformer reaches 90 °C. When the temperature drops to 75 °C, the device automatically reconnects to the mains.

How do you experience it

The response time of an amplifier to an audio signal is considerably shorter when using a Power Conditioner, especially at lower frequencies, this shorter response time also benefits the reproduction of transients. The dynamics are dramatically increased, resulting in more realistic-sounding musical instruments and cinematic SFX.
During the Power Conditioners demos, most listeners will experience the increase in dynamics as if the volume was turned up a little with the same volume control position. The placement of instruments and the height, width and depth of the soundstage increase, there is clearly more “air around the instruments”, all in all a huge improvement. We dare to say that everyone is really enthusiastic after a demo. We often hear: ”I really did not expect this” and “What a huge improvement”. This improvement is already clearly audible on ALL somewhat serious audio equipment!

Applications

The Audes ST-900 produces virtually no acoustic noise, making it extremely suitable for use in recording studios, listening rooms at the Hifi dealer, but of course also in combination with audio-video equipment at home, with the aim of giving you a magnificent “live” experience of your favorite music and/or movie

Using the ST-900 with AV equipment, including solid state and tube equipment, significantly improves the quality of the sound as well as the picture. The best result is achieved by connecting the entire installation to the Power Conditioner.
It no longer matters how you insert the plug into the socket!

Test Audes

During highly dynamic parts of an audio track (eg Tutti Fortissimo of a full symphonic orchestra, sounds of large ethnic drums, bass parts of experimental electronic music and cinematic SFX) a (power) amplifier draws enormous current peaks from the mains. Values ​​from 50 to 100 A are certainly no exception, the voltage level (230 V) must remain constant under these harsh conditions, so without dips.
An ordinary household socket, which is connected with long electrical cables to a distribution board in the meter box, cannot supply such current levels because of the relatively high output impedance. ST-900 has very low DC output resistance and can therefore easily deliver high current peaks without voltage drop. This is achieved by using a transformer with a very large core and running it with minimal inductance. As a result, the response time of an amplifier to an audio signal is considerably shorter, especially at lower frequencies, which benefits the reproduction of transients. This dramatically increases dynamics, resulting in more realistic-sounding musical instruments and cinematic SFX.
Another problem in the power supply of high-value equipment is contamination in electrical networks. This is caused, among other things, by switches, controllers of electric motors, dimmers, switching power supplies of modern AV equipment, not to mention solar panels that are used in the vicinity.
The high-quality CEE 7/3 sockets are galvanically isolated from the external electrical network. The transformer is provided with proper shielding against electromagnetic disturbances from outside.
Electrical disturbances are eliminated by the symmetrical construction of the primary and secondary winding of the transformer.
The secondary winding is divided into two halves and has a center tap, which is connected to the ground terminals of each CEE 7/3 socket.
The transformer of the ST-900 is designed to act as a low-pass filter. Because almost all electrical network disturbances occur at higher frequencies, the cut-off frequency is 800 Hz. The filter effect is partly caused by the self-induction of the very large core; the magnetic flux hardly changes when contaminated in electrical networks. Foregoing technical aspects make it possible to remove almost all electrical network contamination, providing a reliable and very high quality clean power supply for AV equipment.
When switched on, the transformer draws a peak current of approximately 20 A. A special switch-on resistor limits this peak current, so that the switch-on current of the Power Conditioner is not too high.
Audes Power Conditioners are equipped with overload protection and are thermally protected, which switches off the transformer as soon as the temperature of the transformer reaches 90 ° C. If the temperature drops to 75°C, the device automatically reconnects to the mains. The transformer is designed in such a way that the number of primary turns is maximum. As a result, the power consumption of an unloaded ST-900 is very low.
The ST-900 produces virtually no acoustic noise, making it ideal for use in recording studios, (home) cinemas, showrooms, but of course also in combination with your audio equipment at home, with the aim of giving you a magnificent “live” experience of your favorite to give music.

Upgrade
Do you want to get more out of your HiFi set? Then this is a nice upgrade. Due to the very stable voltage/current supply, the ST-900 gives more detail and depth to the reproduction of each set that can be connected to it.
The ST-900 has 5 power connections, so enough for the average HiFi set. You can connect all your devices in your set to this. For the heavier sets with more power demand, we have the ST-1500 and ST-3000.
