The iP 2100 is a space-saving power amplifier, ideal for use in
installations as well as in cost-effective live sound systems.

The Iron Power (iP) family of power amplifiers is the new compact and
versatile line of professional power amplifiers with classic toroidal iron
transformers. To achieve a compact design, the latest semiconductor tech­nology is utilized. This, together with Lab.gruppen’s proprietary copper
cooling system, Inte rcooler®, enhances the 2 ohms capacity.

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:

Multiple positions Gain switch

To meet the demands for a flexible gain structure in the system, Lab.gruppen
offers a multiple position gain switch. The maximum amplifier gain can be set
to all industry standards: 20, 23, 26, 29, 32, 35, 38 and 41 dB.

Versatile input connection

With the Neutrik Combo-jack we offer both the professional XLR-type
_standard and the semi-pro 1/4” TRS phono-jacks. For installations the 3-pin
Phoenix terminal block may be handier.

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:

– ALStm 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.
