Klark Teknik DSP Technology Class-D power amplifier
iQ8
The 2,500-Watt iQ8 is a powered two-way loudspeaker ideally suited for a wide range of portable and fixed installation, music and speech sound reinforcement applications. The driver complement includes an 8" low frequency driver with a low mass voice coil for improved transient response, and a high temperature 1" compression driver with copper clad aluminium voice coil for extended high frequency reproduction.
Equipped with a very efficient and lightweight two channel Klark Teknik Class-D power amplifier, the iQ8 provides an impressive 2,500 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 for remarkable full range response at low volume levels, and transparent limiting for the utmost clarity at high output levels – and long-term reliability. iQ8’s advanced DSP speaker modelling presets include detailed and accurate models of some of the audio industry’s most-respected loudspeakers.
Klark Teknik also developed a highly versatile Spatial Contour Control (SCC) DSP function, which allows the user to easily optimise the iQ8’s frequency response for the physical speaker placement. This advanced functionality provides frequency compensation for stand, floor, wall or ceiling placement, much like the adjustments commonly found on studio reference monitors.
On the rear panel amplifier module, you will find a fully featured user interface consisting of an LCD display, the Channel A and B gain controls, and a single rotary encoder for intuitive access to level, EQ, Speaker modelling, SCC, Subwoofer Integration and Feedback Control (FBI). In addition to the two combination balanced XLR/jack inputs, balanced XLR outputs for each of the two independent channels, and a Mix Out XLR connector, the iQ8 features a mic/line switch and level control with signal present LED on each channel.
The iQ8 also features our proprietary ULTRANET technology, which allows the use of CAT5 cables for transmitting pristine multi-channel audio signals and other information between ULTRANET-enabled products, such as digital mixers and personal monitor systems. This digital distribution networking not only eliminates the potential for RFI and crosstalk so common to analogue methods, but also significantly reduces the setup or installation time required. An onboard USB port provides access for remote control of the iQ8 via PC computer, as well as DSP and speaker modelling firmware updates.
The lightweight fibre glass reinforced composite enclosure is fitted with a rugged powder coated perforated steel mesh grille and multiple internal rigging points for permanent installations. The iQ8 is also fitted with a dual angle pole mount socket, allowing the enclosure to be pole mounted straight on, or raised and angled downwards for optimal audience coverage. Mains power input and link output is provided via Neutrik powerCON* connectors.
