The LAB 1200C gives the opportunity of use in several applications, such as; in
multi-channel monitor systems, fourchannel reproduction, and compact amplification
in active 2-, 3-, and 4-way systems.

The LAB 1200C gives the possibility to bridge connect one or two of the two pair of channels (channel A and B and/ or channel C and D). These bridge mode combinations solve most of the problems concerning different impedance’s and maximum power handing of loudspeakers.

The switch-mode power supply is the modern solution of the weight and size problem. With switch technology operating at a high frequency, it is possible to use ferrite transformers instead of heavy iron transformers and large electrolytic capacitors.
Switch-mode technology has been applied in power supplies in TV-sets during
the latest 30 years. But in the LAB 1200C the power capacitivity is 10 times larger. We have designed the LAB 1200C to obtain the same characteristics as a conventional
power supply. Thanks to the switch-mode power supply it is easy to get the DC-rail voltage stabilised. This is made by controlling the magnetic energy in the ferrite transformer with a
pulse width processor and magnetic “Flux Sense” windings. Twenty-four 250 watt bipolar power transistors constitute the output stages, which are totally complimentary. The
power transistors are cooled by a solid copper cooler, called Intercooler®, originally
designed for our LAB 1300 power amplifier.

LAB. GRUPPEN’s specially designed thermal feedback circuit protects against thermal breakdown. The LAB 1200C is completely shortcircuit protected . The LAB 1200C is
equipped with LAB. GRUPPEN’s Adaptive Limiting SystemTM short circuit
protection, which permits very high peak-currents, but still holds the transistors
within the so-called “Safe Operation Area” at the present operating voltage.
This makes it possible to run loudspeakers with impedance variations,
which are considerably lower than the lowest permitted impedance of the
power amplifier.
