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 moni-

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.

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.

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.
