The Solid Foundation:
Lab.gruppen Core Technologies
D Series is built around proven Lab.gruppen amplifier technologies
with an established track record of undisputed sonic excellence
and rock-solid reliability in both touring and high performance for
large scale installed applications.
•
Regulated Switch-Mode Power Supply (R.SMPS) –
A fully regulated design that ensures stable output power
independent of deviations in the mains voltage
•
Breaker Emulation Limiter (BEL) –
Dedicated algorithm anticipates breaker behavior to prevent
power interruption
•
Under-voltage Limiting (UVL) –
Reduces power output for continued operation despite
severe voltage drops
•
Best-in-class Power Factor Correction (PFC) –
Unique Current Draw Modeling (CDM™) reduces mains
peak draw.
•
Patented Class TD® Output Stage –
Combines the efficiency of Class D with the sonic qualities of
Class B topologies.
•
Inter-Sample Voltage Peak Limiter (ISVPL™) –
Digitally controlled peak limiter with exceptional accuracy
for maintaining sonic purity
•
Intercooler® Cooling System –
Extraordinarily efficient, the copper-finned Intercooler is
mounted transverse to air flow to prevent “heat island”
overheating of last output devices
•
Full Suite of Protection Circuits –
D Series units and connected loads protected by Current
Average Limiter (CAL), Very High Frequency Protection (VHF),
Direct Current Protection (DC), Short Circuit Protection,
Current Clip Limiter, Voltage Clip Limiter
