AMPLIFIERS - GUIDE 153
KIND AUDIO | DD+ / DQ+
www.kindaudio.com
KIND launches its MkII energy saving digital DD+ / DQ+ amplifier series, consisting of the 2-channel DD+ range and the 4-channel DQ+ range. Both amplifier series are manufactured in Italy and offer premium quality, high level sound performance, two ohm capability, lightweight and compact size. The five DD+ models range from 2 x 1,000W to 2 x 2,600W into four ohm, and 2 x 1,800W to 2 x 4,000W into two ohm. The five DQ+ models range from 4 x 750W to 4 x 2,100W into four ophm, and 4 x 1,250W to 4 x 2,500W into two ohm. The DD+ / DQ+ series incorporate comprehensive warning and protection features to safeguard the amplifier and loudspeakers. All models are fitted with limiter and multiple gain with seven step of 3dB from 26 to 44dB. The amplifiers have an open input architecture and can ac- commodate an optional AES / EBU in-out, DSP and remote control board. All the models have a regulated switch mode power supply with PFC, works from 95 to 265VAC, with this advanced solution the amplifier output power is not affected by mains fluctuation.
KLING & FREITAG | TOPAS
www.kling-freitag.biz
The Kling & Freitag Topas is a network-compatible DSP amplifier particularly adapted for optimised use with Kling & Freitag speakers. However, the operation of other speaker systems is possible. By Ethernet, Topas may be added and turned off, controlled and monitored in a very flexible way. Four freely assignable inputs may be controlled by analog voltage levels. Four outputs are available in the open-col- lector circuit. Free assignable events like error and log status, signal, starting delay for further output stages (power sequencing) and output stage state can be freely assigned to the inputs by the web interface. In the monitored pro sound installations, the Topas is recommendable because of the integrated speaker monitoring and signaling by email. Further equipment characteristics are the integrated web server for the clear lay-out of configuration, the easy finding of all appliances in the net by AutoIP / mDNS and the configurable access control by username and password. The Topas design permits the monitoring of the internal protection circuit (clipping, DC, short-circuit, temperature, supply tension) by remote software or by WebClient. The high functionality, performance and extensibility of the Topas system is ensuring a high reliability level for planning and return of investment.
LAB.GRUPPEN | E SERIES
www.labgruppen.com
Lab.gruppen’s E Series amplifier range provides ample power reserves with amazingly low power consumption, therefore reducing the total cost of ownership below that of conventional designs. E Series utilises much of the unique design philosophy and energy-efficient concepts debuted in the Swedish company’s flagship PLM 20000Q touring amplifier, but here deployed in a 1U, install-centric platform. Certified as Energy Star 2.1 compliant, E Series power amplifiers are extraordinarily efficient both in terms of net operating efficiency and typical current draw. In this respect, the power-to-current-draw ratio for burst signals with 1/8th average power is 400W output for 1A of line current at 120V mains - a performance characteristic matched only by the PLM 20000Q. Control via third-party systems is enabled via GPIO, and build quality is robust in the
Lab.gruppen tradition. The E Series comprises three two-channel power amplifiers, all incorporating
Lab.gruppen’s IDEEA (IntelliDrive Energy Efficient Amplifier) technologies. Nominal output power ratings per channel (@ four ohms or 70V) are 600W, 400W, and 200W for, respectively, the E 12:2, E 8:2, and E 4:2. However, significantly higher per-channel outputs are possible with asym- metrical loading and proper setting of
Lab.gruppen’s proprietary Rail Sensing Limiter (RSL).
LYNX AUDIO | DSX SERIES
www.lynxproaudio.com
The DSX amplifiers offer a powerful, reliable and lightweight DSP controlled amplifier. Select from 16 models with power output from 1,200W to 6,000W, two or four channel models, all offering plenty of power level with low distortion and a weight of around only 8kg each. Every DSX amplifier has an integrated digital signal processor, a complete protection package, including the PMS power management system to control the amount of power that the amp delivers, ICL intelligent clip limiting system, muting at turn on and a full pack of features for fail-safe operation. The DSX series offer a fully programmable DSP, including limiter compressor, crossover, noise gate, delay, PEQ, gain control, Ethernet control and digital inputs in AES / EBU or EtherSound. With 0.5ms fixed latency this DSP is one of the lowest latency processors available. All DSX amplifiers deliver a wide dynamic range of 120dB, high performance Cirrus Logic AD & DA 24 bit converters running at 96kHZ. The internal DSP processing works with double precision in floating point, achieving an internal resolution of 56 bit, one of the largest resolutions available on the market today. This enables the use of high precision filters with extremely low distortion delivering unbeatable sound clarity and quality.
