Power Dynamics PDD900 Digital Amplifier 2x450W 4ohm

Ενισχυτής 2 x 450W, της σειράς PDD. Η σειρά PDD διαφέρει απο τις άλλες, γιατι υιοθετεί την τεχνολογία Class D. Το κόστος είναι ανάλογο της Class A/B, αλλά η ισχύς, αξιοπιστία και απόδοση είναι σε σημαντικά υψηλότερα επίπεδα. Οι ενισχυτές της σειράς PDD είναι ιδανικοί για επαγγελματική χρήση. Λόγω του χαμηλού βάρους και του μεγέθους 1U, αυτός ο ενισχυτής είναι εύκολο να μεταφερθεί και πιάνει ελάχιστο χώρο.

Output power: 8 Ohms

The high efficiency of the ED series enables maximum efficiency with low heat generation.

A new and unique Class-H circuity technology using state of the art SMD Surface Mount Technology with a reduced number of components offering performance levels exceeding audiophile levels like a slew rate of 50V/µs and high-end extended dynamic sound. The amplifier provides 2x300W into 4 Ohm is equipped complete with temperature-controlled fan cooling, all common protective circuits such as over-temperature, short circuit, RFI and soft start.
The integral soft clip limiter protects against damage to the connected loudspeakers, the activity of a protective circuit, signal and limiter are shown for each channel by LEDʼs.

Solid DYNACORD amplifier technology at highly competitive prices.
These amplifiers offer high, stable power output and a high efficiency factor on the high performance level and are therefore the ideal choice for driving a multitude of mobile and club systems. SL series power amplifiers are equipped with a comprehensive protection package and dynamic limiters.
The integrated, switchable Low-Pass Notch filter (a typical DYNACORD special feature) corrects the frequency response and optimizes the transient behaviour of loudspeakers.
