Η προσθήκη του PP 4 στο οικιακό σύστημα, ζωντανεύει τα LP με τη μορφή εκτεταμένου και πλούσιου ήχου. Προσφέρει εξαιρετική και μετρημένη απόδοση ήχου, συνδυάζει δύο απλές λύσεις – το PP 4 Digital Phono και τον προενισχυτή USB – σε μια μικρή συσκευή, καθιστώντας εύκολη την προσθήκη phono σε στερεοφωνικούς ενισχυτές και δέκτες AV χωρίς είσοδο phono. Το PP 4 χρησιμοποιεί θωρακισμένο καλώδιο USB και έλεγχο στάθμης εγγραφής, που μειώνει τον θόρυβο και βελτιώνει τη διαδικασία μετατροπής αναλογικού σε ψηφιακό. Ως μέρος της δέσμευσης της NAD για το περιβάλλον, το PP 4 διαθέτει ένα πιο αποτελεσματικό «πράσινο» τροφοδοτικό που μειώνει την κατανάλωση ενέργειας. Διαθέτει επίσης λειτουργία Auto Power Down που εξοικονομεί ενέργεια απενεργοποιώντας όταν δεν χρησιμοποιείται.

With the addition of the PP 4 to your home system, the LPs you cherish the most come alive in the form of expansive and rich sound. Offering superb and measured sonic performance, NAD combines two simple solutions – the PP 4 Digital Phono and the USB Preamplifier – into one small device, making it easy to add phono to stereo amplifiers and AV receivers without a phono input. The PP 4 uses a shielded USB cable and recording level control, which reduces noise and improves the analogue-to-digital conversion process. As part of NAD’s commitment to the environment, the PP 4 features a more efficient “green” power supply that reduces power consumption. It also has an Auto Power Down feature that saves energy by shutting off when not in use.

Cary Audio has always supported playback of vinyl records, and today there is a revival of the LP as a serious format, both for audiophiles and for the general music public. With the new VT-500, even the most demanding vinyl enthusiast will realize this exotic unit is dedicated to nothing short of incomparable vinyl playback.

About the VT-500 Phono Preamplifier

The VT-500 is a vacuum tube stereo phono preamplifier utilizing four (4) 6SL7 dual triode tubes. The RIAA equalization curve is derived from a passive RC circuit located between the two gain stages. The VT-500 uses a fully regulated power supply housed in a large separate heavy-duty external power supply chassis ensuring an extremely quiet operation. The MC section uses two high quality step-up transformers providing enough gain for use with any MC cartridge with a very low noise floor. The VT-500 offers inputs and selectable loading to match almost any moving-magnet or moving-coil phono cartridge. This will optimize the response to best match your cartridge.

For the analog lover, the VT-500 is a magical blend of art and technology that will add to your music listening enjoyment hour after hour. You’ll hear subtle shadings and exciting dynamic contrasts on all types of music. If you are serious about your vinyl music collection and your turntable, the VT-500 should be part of your system.

The MP1100 Vacuum Tube Phono Preamplifier will give vinyl lovers a new level of musical enjoyment and exhilaration. It’s filled to the brim with everything you need to not only play new records or pressings from the early days of vinyl, but it will also get every last musical note and nuance out of them – including some you may have never heard before.

«Phono stages: I dream about them, but I never had a dream like this. The new MP1100 phono stage from McIntosh is quite unlike anything that would pop into my head in the middle of the night, but McIntosh does a lot of things differently – and also very well. Their new MP1100 phono stage… is both fascinating and impressive… a phono stage that has it all.» – Hi-Fi World

The MP1100 is designed first and foremost for analog audio and achieves our most accurate equalization ever. It utilizes four 12AX7A vacuum tubes, with 2 tubes used per channel in a fully balanced configuration – making it our very first fully balanced vacuum tube phono stage. For those with multiple turntables or tonearms, there are 3 sets of RCA phono inputs; XLR connectors are also available on 1 of the inputs. All phono inputs allow for adjusting both resistance (7 settings) and capacitance (8 settings). For ease of use, it comes pre-programmed with profiles for Moving Coil and Moving Magnet cartridges as well as the McIntosh MT10 and MT5 turntables. Five additional profiles are included that are fully customizable and can be assigned to any phono input. RIAA, LP, NAB, AES and 78 analog equalization curves are included.

The MP1100 exhibits «an absolute accuracy in the timbre,» making it sound very close to the real instrument. Winner of Top Quality Award. – Fedeltà del Suono

«The MP1100 transformed itself into a time machine… I was sitting not just in the front row, but right beside Carole King and James Taylor, totally immersed in the music.» – Part-Time Audiophile

Two fairly rare but highly useful analog filters are built-in: a Rumble Filter helps remove noise that may have seeped into a song during the recording process; while a Scratch Filter can help restore the sound of frequently-played records that may have become a little worn, or records that may have some damage. Adjustable gain from 40dB to 64dB allows for further customization, while a Mono setting permits proper playback of mono recordings. In addition, there’s a pair each of balanced and unbalanced high level inputs for connecting other sources. For connecting to the rest of your audio system, there are a pair each of balanced and unbalanced stereo outputs.

«It’s one of a kind… very easy to use and to configure… from an acoustic point of view… [it] is the best phono preamplifier» from McIntosh. – Suono

Not to completely overlook the merits of digital audio, the MP1100 has an optical, coaxial and USB output. These digital outputs are fixed at 24-bits and can be set to either 96kHz or 192kHz. When used with a properly configured conversion program, the USB output can be used to “rip” your albums to your computer. Our digital output clipping indicator will notify you when distortion caused by loud sections in a song is being recorded to the file, allowing you to adjust your settings in order to create pristine, distortion free digital versions of your albums. For pure analog use, the digital outputs can be completely disabled and powered down.

«A serious stand-alone phonostage… Perhaps one of the quietest all tube phonostages we’ve heard… For someone wanting a reasonably priced, all-encompassing vinyl playback and archiving workstation with multiple turntables, the MP1100 is without peer.» – Tone Audio

To combat noise, the MP1100 features a dual mono design with the left and right audio channels electrically and mechanically isolated from each other while the power supplies are electronically separated. It can be paired with any preamplifier, integrated amplifier or home theater processor that includes volume control. An ideal match is our C1100 Vacuum Tube Preamplifier which also has a dual mono design; both also share the same polished stainless steel and hairline brushed black Titanium stainless steel chassis to create a cohesive appearance. Classic McIntosh design cues complete the MP1100. Contact your local dealer to learn more. 

Τεχνικά Χαρακτηριστικά

The MP100 is the first dedicated phono preamplifier from McIntosh and is designed to help both new and experienced vinyl lovers get the most fidelity, performance and – most importantly – enjoyment from their albums.
Like all McIntosh products, the MP100 is packed with features designed specifically for the vinyl lover including: Moving Coil and Moving Magnet inputs; Moving Coil and Moving Magnet adjustable loading (6 settings each); balanced and unbalanced analog outputs; optical, coax and USB digital outputs; and a Mono switch for when playing mono records to decrease noise and play the signal correctly.
There are many ways to integrate the MP100 into your audio system. If you’re new to vinyl and just building your system, it can become the main part of your setup. Or if you already have a system with an older preamp you don’t want to part with, the MP100 is an excellent way to add modern phono features. If you’ve got a home theater system and would like to add a turntable, the MP100 is an easy way to add full phono preamp capabilities without having to get a full-sized stereo preamp that would undoubtedly duplicate many of your home theater processor’s features.
While spinning vinyl on a turntable is a great and unique way to enjoy music, there’s no denying the convenience of having digital versions of the albums. When used with a properly configured conversion program, the MP100 can “rip” the records to a computer via USB to produce high quality digital files. The digital outputs are fixed at 24-bit/96kHz to capture the full dynamic range of a record while optimizing digital file size. If an album has a very loud section, the clipping indicator will alert you so you can lower the digital output in order to produce a distortion-free recording.
Compact in size at just 3” tall, it has many ageless McIntosh design cues. It shares the same 11.5” narrow chassis design as the MXA70 Integrated Audio System​, MHA100 Headphone Amplifier​ and MB50 Streaming Audio Player to help build a cohesive system. It can also easily be added to a system comprised of standard, wider width chassis. Contact your local dealer to learn more. ​

Ακουστικές Εντυπώσεις

O PA-23 δημιούργησε μια αίσθηση δυναμικής απόδοσης. Χωρίς εμφανή θόρυβο, ακούστηκε δυναμικός και καλόηχος. Χαμηλά πήραμε καλό έλεγχο με σωστό σώμα που απέκλινε -ίσως- ελάχιστα προς το υπερελεγχόμενο χωρίς να αφήνει περιθώρια για παράπονα. Οι φίλοι των ρυθμικών κομματιών θα τον συμπαθήσουν πολύ. Η μεσαία περιοχή αποδόθηκε με πολύ καλή λεπτομέρεια, μια αίσθηση εγγύτητας και καλές δυνατότητες περιγραφής των ηχοχρωμάτων. Ο προενισχυτής απέδωσε πολύ καλά την δομή των μουσικών κομματιών και φάνηκε πολύ αναλυτικός. Η περιοχή των υψηλών συχνοτήτων ακούστηκε ισορροπημένη με καλή έκταση, αρκετά γρήγορη, αποκλίνοντας λίγο προς το φωτεινό-λαμπρό, χωρίς να κουράζει ή προβάλλεται υπερβολικά και χωρίς λόγο. Η στερεοφωνική εικόνα ήταν αρκετά καλή, με μικρή τάση για ασάφεια στον οριζόντιο άξονα η οποία θα μπορούσε να εκληφθεί και ως “ατμόσφαιρα”.

Τελικώς…

… παρά το χαμηλό του κόστος, ο PA-23 είναι ένας καλοκατασκευασμένος προενισχυτής με καλές επιδόσεις (ειδικά σε θέματα θορύβου) και ενδιαφέροντα ήχο που έχει ως δυνατό σημείο την απόδοση των ρυθμικών μερών, κυρίως λόγω του δυναμικού αλλά και ελεγχόμενου χαρακτήρα του. Το βασικό του μειονέκτημα είναι η διαφορά στο κέρδος μεταξύ των καναλιών του, κάτι που θα πρέπει να προσέξει η εταιρία.
