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 Position Gain Switch (MPGS)
To meet the demands for a flexible gain structure in the system, Lab.gruppen offers the MPGS. 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:
- 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.
