LAB GRUPPEN iP 2100 2X700W POWER AMPLIFIER

The iP 2100 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.

Key Features:
2 x 425 watts @ 8 ?
2 x 700 watts @ 4 ?
2 x 1050 watts @ 2 ?
(Measured just below clip level, with both channels driven)
Compact design: 2U high
Intercooler? cooling system with front-to-rear airflow
Multiple positions gain switch
Easily accessible dust filter
Improved low-end power bandwidth
Neutrik Combo jack and Phoenix terminal block input connectors
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:

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 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:
ALStm 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.

The high efficiency of the ED series enables maximum efficiency with low heat generation.

A new and unique Class-H circuity technology using state of the art SMD Surface Mount Technology with a reduced number of components offering performance levels exceeding audiophile levels like a slew rate of 50V/µs and high-end extended dynamic sound. The 2U amplifier provides 2x550W into 4 Ohm is equipped complete with temperature-controlled fan cooling, all common protective circuits such as over-temperature, short circuit, RFI and soft start.
The integral soft clip limiter protects against damage to the connected loudspeakers, the activity of a protective circuit, signal and limiter are shown for each channel by LEDʼs.

This professional stereo power amplifier, working in class-H mode, provides 2x800W, at an efficiency of around 85%.

A passive transformer based power supply and hand selected components makes this power rating possible with exceptional audio quality and absolute reliability, even in the 2 Ohm mode. The output stage is fully protected against over-temperature, short circuit, RFI and equipped with soft start circuit and temperature-controlled fan cooling.  The integral soft clip limiter protects against damage to the connected loudspeakers.  The activity of a protective circuit, signal and limiter is shown for each channel by LEDʼs.

Crownʼs new CTs series of power amplifiers are remarkable for their loud, punchy sound; sustained, tight bass; and superior protection against overheating and overload. This paper explains the design features behind those advantages. After reading this information, youʼll know why Crown CTs amps sound better than the competition. CTs amplifiers can provide large amounts of power into various loads, such as 2, 4, 8 ohms and 70V. With most power amps, the maximum output power tends to drop as the load impedance increases. But with the CTs series, the power stays the same at almost any impedance. 2-ohm Dual (per Ch.) 250W 4-ohm Dual (per Ch.) 600W 8-ohm Dual (per Ch.) 600W 16-ohm Dual (per Ch.) 300W 70V Dual (per Ch.) 600W 4-ohm Bridge 500W 8-ohm Bridge 1200W 16-ohm Bridge 1200W 140V Bridge 1200W Crown switching power supply for less weight Sustained Power on long-duration signals due to regulated, "stiff” power supplies with incredible energy storage (huge filter capacitors). Extra Hidden Power during high-level transients and during incomplete use of all the channels. Overheating and overload protection thanks to the sophisticated TLC circuitry which compresses the signal only when needed. Compression is controlled not by temperature, but by signal voltage. This keeps the loudness up during compression more than with competitive amps.
