LAB GRUPPEN iP 1150Q 4CHANNELS 4X200W POWER AMPLIFIER

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.
 
Key Features:

4 x 130 watts @ 8 ?
4 x 200 watts @ 4 ?
4 x 270 watts @ 2 ?
(Measured just below clip level, with all channels driven)
Compact design: 2U high
Intercooler? cooling system with front-to-rear airflow
Easily accessible dust filter
Improved low-end power bandwidth
Neutrik Combo jack
Bridged mono outputs in one SpeakOn connector

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.
 

PA Power Amplifier 4 x 160 W 4 Ohms

The C 16:4 is one of two mid-power, four-channel amplifiers in the C Series family. Attractively packaged in a 2U chassis, it provides 4 × 400 W output into 4 ohm loads.

C Series amplifiers are uniquely capable of adapting to a wide variety of demanding load conditions. Each channel has an individually configurable Voltage Peak Limiter (VPL™), which allows the output to be optimized for any loudspeaker load – whether a single large subwoofer or a series of small 100/70 V loudspeakers. VPL works in combination with adjustable input gain to achieve maximum headroom regardless of input levels or output impedances.

Every C Series is ready for the NomadLink® network right out of the box. With NomadLink, key amplifier parameters are displayed via DeviceControl software, and remote control of channel mutes and power on/off is under network control.

Note 1): Automatic -6 dB gain compensation when bridging channels. Ch.’s A+B and/or C+D, can be bridged individually.
Note 2): PAL can reduce the maximum output power to keep the power supply operating safely, and/or to prevent excessive current draw tripping the mains breaker.
Refer to Operation Manual.
Note 3): For sine waves, peak voltage output values translate to Vrms with the formula V/1.41 = Vrms. E.g. 100 V peak equals app. 70 Vrms.
Hence, outputs can be set for high-impedance loads without requiring a transformer.
All specifications are subject to change without notice.

The DPA series amplifiers are digital power amplifiers designed to meet the specialized needs of sound contractors for Multi-Zone distributed speaker systems. They are designed in six different models of Class D power amplifiers, divided in three different architectures to meet the requirements for all kinds of applications.

They combine the best of all features in one single series of amplifiers, providing an outstanding sound quality with all the known advantages of Class D Amplifiers. Such as the excellent efficiency and very low heat dissipation. And due to the complete passively cooled entity only a minimal of maintenance is needed, while ensuring maximum reliability.

The small size of a single rack space make them very interesting for fixed rack mount as well as mobile applications.
