The iP 1150Q is a space-saving four channel power amplifier, ideal for use in
installations as well as in cost-effective live sound systems.
The iP 1150Q offers a choice of applications, such as in multi-channel monitor
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 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 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:
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.
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.
