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 versa-
tile line of professional power amplifiers with classic toroidal iron transform-
ers.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 installa-
tion 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
standardand thesemi-pro1/4”TRSphono-jacks.Forinstallations 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:
–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 frequen-
cy 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 loud-
speakers,whilst maintaining full peak power.
