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.

Κατάλληλος για εγκαταστάσεις & P.A. 10,3Kg. | The LD Systems DP600 Power Amplifier offers an amplifiying level of 2 x 300 W 2 Ohm
The new DEEP2 amp series features four class-H power amplifiers with toroidal core offering amplifying levels from 2 x 400 W till 2 x 810 W at 4 Ohm. During the development of this series we attached a great importance to the reliability and the durability of the amps in continuous operation, this is why we used exclusively high end and selected components for the construction of these products.
The DEEP2 series features a Clip Limiter as well as every common protection circuits. These amps are 2 Ohm and 4 Ohm (bridge) stable in continuous operation. On the rear panel you will find all the common In- and Outputs.
The DEEP2 series will convince every user thanks to a dynamic and very clear sound which is perfectly adapted for Subbass applications as well as for multifunctional speakers. All models are lightweight and feature a robust steel plate housing and a very user friendly and compact design.
The DEEP2 series will prove to be a profitable and reliable choice for bands, renting companies and professional users thanks to its excellent price/performance ratio.

COMPACT MODERN DESIGN
Compact size (2U-Rack Height) with up to 1200W per channel@2ohms
these amps save valuable rack space without compromising power output.
HIGH CURRENT TOROIDAL TRANSFORMER
A high-current toroidal transformer saves rack space
and minimizes hum and noise.
EXCELLENT SOUND QUALITY
The low T.H.D.(0.05%) and high damping factor (400 or higher)
gives excellent sound quality.
2 STAGE POWER SUPPLY
The high-power units (L1800 and L2400) have a 2-Stage Class-H design
that maximizes their performance.
EQUIPPED WITH 30Hz or 50Hz HPF
All amplifiers are equipped with high-pass filters on each channel to
help maintain sound quality, yet help protect the loudspeakers.
EXTENSIVE PROTECTION CIRCUITS
Extensive protection circuits monitor over voltage/current conditions, overheating,
output shorts, and DC voltage to improve performance and reliability.
CLIP-LIMITER CIRCUITS
Clip-limiters on each channel are provided to help prevent
distortion due to excessive signal levels.
