Equipped with a very efficient and lightweight KLARK TEKNIK Class-D power amplifier, the iQ18B provides an impressive 3000 Watts of output power. A high degree of control over the loudspeaker system's performance is managed by a sophisticated, but easy-to-use KLARK TEKNIK digital signal processor (DSP), which provides dynamic EQ and transparent limiting for the utmost punch and definition at high output levels with long-term reliability. iQ18B's advanced DSP speaker modeling presets include detailed and accurate models of some of the audio industry's most-respected speaker systems.

Fully featured user interface consisting of an LCD display, the Channel A/B gain control, and a single rotary encoder for intuitive access to level, EQ, Speaker modelling, and Feedback Control (FBI). In addition to the two combination balanced XLR/jack inputs and balanced XLR outputs for powered satellite loudspeakers, the iQ18B features a mic/line switch and level control with signal present LED.

ULTRANET technology allows the use of Cat 5 cables for transmitting pristine multichannel audio signals and other information between ULTRANET-enabled products such as digital mixers, powered loudspeakers, and personal monitor systems. This digital distribution networking not only eliminates the potential for RFI and crosstalk so common to analog methods, but also significantly reduces the setup or installation time required. An onboard USB port provides access for remote control of the iQ18B via PC computer, and DSP and speaker modeling firmware updates.

The birch plywood enclosure is finished in a hard-wearing semi-matte-black paint and fitted with a rugged powder coated perforated steel-mesh grille, standard 1.4" (35mm) pole mount to support a satellite speaker, and plated steel casters with rubber wheels. A mains power input and link output are provided via Neutrik powerCON connectors.
