The iP 900 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, Intercooler?,
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
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.
