# Very low noise # Low distortion 


The ΤM-180 delivers 180WRMS at 8ohms per channel.

Amplification circuit has eight bipolar power transistors per channel in symmetrical configuration.

TM-180 has an engineered architecture with chassis specially designed to isolate the audio circuits from interference and noise.

Τhe redesigned chassis provides enough ventilation.

When viewed from above at the left side are two heat sinks.

At the right side of each chassis are found two power transformers.

The compact design of the circuitry allows short signal path so parasitic capacitance, delay and phase shift are minimized.

Two microcontrollers, one per channel monitors the temperature with 0.1deg accuracy (adjustment is done watching two 3 digits indicators inside the chassis) and interrupts the (channel) power supply in case of overheating; the reset is automatic.

A small amount of negative feedback is applied.

TΜ-180 bass extension and stability during demanding musical passages, coupled with relatively low noise, impart a sense of ease to the presentation.

Soundstage depth is in keeping with other solid state amps at its price level, but width and height are exceptional.

ΤM-180 offers tonal neutrality, dynamic control, expansive sound staging, fine resolution, plenty of power reserves, and great musical expressiveness.












# Πολύ χαμηλός θόρυβος # Χαμηλή παραμόρφωση 


O TM-180 αποδίδει 180WRMS στα 8ohms ανά κανάλι.

Το κύκλωμα ενίσχυσης έχει οκτώ bipolar τρανζίστορ ισχύος ανά κανάλι σε συμμετρική διάταξη.

Ο TM-180 έχει μηχανική αρχιτεκτονική με πλαίσιο ειδικά σχεδιασμένο να απομονώσει τα κυκλώματα ήχου από παρεμβολές και θόρυβο.

Όπως παρατηρείται από πάνω στην αριστερή πλευρά βρίσκονται δύο ψύκτρες.

Στην δεξιά πλευρά κάθε σασί είναι τοποθετημένοι δύο μετασχηματιστές τροφοδοσίας.

Η συμπαγής σχεδίαση του κυκλώματος επιτρέπει μικρή διαδρομή σήματος έτσι η παρασιτική χωρητικότητα, η καθυστέρηση και η μετατόπιση φάσης ελαχιστοποιούνται.
