tor systems, four-channel reproduction and compact amplification in active
2-, 3-, and 4-way systems.
The iP 1150Q gives the possibility to bridge connect one or two of the two
pairs of channels (channel A and B and/or channel C and D).
The Iron Power (iP) family of power amplifiers is the new compact and
versatile line of professional power amplifiers with classic toroidal iron trans-
formers. To achieve a compact design, the latest semiconductor technology is
utilized. This, together with Lab.gruppen’s proprietary copper cooling sys-
tem, Intercooler®, enhances the 2 ohms capacity. A easily accessible dust filter
on the front ensure a clean front-to-rear airflow.

tem, Intercooler®, enhances the 2 ohms capacity. A easily accessible dust filter
on the front ensure a clean front-to-rear airflow.
A new Bi-phase wiring scheme also increases the capacity of the power
supply. This extends the power bandwidth in the low end.
Besides the traditionally superb Lab.gruppen sonic performance, there is a
full line of features to make the iP family functional in all situations from
installation to cost-effective live sound systems:

With the Neutrik Combo-jack we offer both the professional XLR-type
standard and the semi-pro 1/4 ” TRS phono-jacks.

Soft Start
Toroidal transformers require a huge amount of start current to build up a
magnetic flux when the amplifier is switched on. Therefore Lab.gruppen have
included a soft start circuit to minimize the risk of blowing the wall fuse and
to reduce flickering in the lighting.

Sophisticated protection circuitry, combining:
– ALS
™
short circuit protection; the Adaptive Limiting System permits very
high peak currents, but keeps the amplifier within the Safe Operation Area.
– DC protection; protects against infrasonic signals
– VHF protection; protects the loudspeakers against strong very high
frequency non-musical signals above the audible range.
– Thermal protection; prevents the amplifier from being overheated. The
protection indicators on the front panel are switched on, as a warning, before
the protection process is initiated.
– AC protection; shuts down the power supply if the line voltage is outside
the operating voltage.
– Clip limiter; prevents severely clipped waveforms from reaching the
loudspeakers, whilst maintaining full peak power.
