H διάσημη Iαπωνική εταιρία παρουσίασε ένα νέο ζευγάρι προενισχυτή και τελικού ενισχυτή στο γνωστό σαμπανιζέ φινίρισμα, με modular αρχιτεκτονική και μερικές ενδιαφέρουσες πατέντες για τον πρώτο και δυνατότητα γεφυρωμένης λειτουργίας για τον δεύτερο.
Ο C-2150 περιλαμβάνει το νέο ρυθμιστικό στάθμης AAVA και ενσωματώνει ένα νέο κύκλωμα προενίσχυσης, που επιτρέπει στον χρήστη να ρυθμίσει τη γωνία φάσης (phase angle) ανεξάρτητα για κάθε μία από τις εισόδους γραμμής του.
Πρόκειται για μοναδικό χαρακτηριστικό που «δικαιώνει» το όνομα της εταιρίας!
O P-4500 αποδίδει 2x180W στα 4Ω και μπορεί να γεφυρωθεί για να φθάσει τα 1000W σε φορτίο 2Ω, διαθέτοντας συντελεστή απόσβεσης 700.

The C-2150 for the first time combines a new topology called ANCC with the AAVA volume control principle. As a result, music reproduction is supple, elegant and full of transparency, with a spatial expression capability that makes one forget the presence of any volume control circuit. With a functionality level close to higher-end models and a versatile array of input and output terminals, plus the choice of adding option boards, the C-2150 provides fully immersive music enjoyment. This next-generation control center will satisfy even the most demanding music lover.
- AAVA volume control with newly developed ANCC feature
- Five line level and two balanced inputs for optimum flexibility
- Recorder connection support
- Logic-control relays for shortest signal paths
- Separate power supplies for left and right channels
- Fully modular construction with individual left / right amplifier units
- Phase selection function
- Tone controls
- Dedicated headphone amplifier
- Option board slots provide additional versatility for digital input handling and analog record playback

The quest for the optimal power amplifier has just taken another giant leap forward. The P-4500 features an instrumentation amplifier configuration realized with discrete semiconductors in the signal path, triple Darlington 4-parallel complementary push-pull architecture and many other technology advantages. The result is an impressive S/N ratio of 121 dB, rated output of 500 watts into 1 ohm (music signals), and a damping factor of 700. A newly developed output protection circuit can also detect any short-circuiting of the speaker terminals, for complete peace of mind. This power amplifier is the ultimate tool for immersive music enjoyment on the highest level.
- Power amplification stage with 4-parallel complementary push-pull configuration
- Linear output characteristics (90 W / 8 ohms, 180 W / 4 ohms, 360 W / 2 ohms)
- 500 W output into ultra-low impedance load of 1 ohm (music signals)
- Instrumentation amplifier principle
- Current feedback topology
- Balanced Remote Sensing
- High damping factor of 700
- Speaker output protection with short-circuit detection
- Highly responsive large peak power meters
- Support for bi-amping and bridged mode
