surrounTec™ [:monolog] Keramik
passive ultra high performance reference loudspeaker system

 

[:monolog] is our analog reference-tool for demanding listeners and mastering engineers. Despite its height of over 1.50m it presents a large one point sound source with a frequency response from infrasonic up to over 40Khz. This 3way monitor is absolutely neutral and without any distortions. The frequency shifts linear from low levels up to high levels without alterations.

A special feature of the surrounTec [:monolog] is the phase coherent playback in combination with the ideal mechanical Time-Alignment of the installed drivers. The result is a perfect step response (all drivers start at the same time at the same place with an identical rising edge). This means not only that all drivers radiate all frequencies from the same place at the same time but also that the phase is passed on between the drivers without noticeable turns. This is realized through our surrounTec™ filters. We archive this by filtering the signal path of every driver seperately until it is flat. This concept means that all indivdual frequency responses add up perfectly at any given time. This loudspeaker behaves like a large broad-band driver and radiates sound correctly with regards to phase and time. The filters are build by hand and we only use Mundorf Supreme Silver/Gold/Oil components and silver solder. It goes without saying that all build-in components are milled from the full block and receive extensive surface treatments.

The main attributes of every [:monolog] are unmatched stress less and effortless listening at any level, ultra neutral and unaltered audio reproduction with precise bass without any overlay effect down to infrasonic playback. This results in true holographic transients. You will not miss bass, overtones nor corporeity. The full frequency response is available at all levels.

The [:monolog] are designed for bi-amping (minimum impedance smaller 2 Ohm!). Thus optionally we offer to equip the subwoofers with one 500Watt analog class D monoblock amplifier each. These amplifiers have a fine power filter and a ring-core transformator for large power reserves and stable power supply. The level adjustment to the mid- and high tone section is done via a fully symmetrical analog level adjuster with 12 individually cascaded single resistors (!) which dampen the level by 1/2 dB each. The cooling fins are milled from the full aluminum block to guarantee maxuimum heat discharge. The input section is symmetrical XLR or chich.

Furthermore we offer class D monoblock amplifiers for the high- and midtone sections as well. These 250Watt strong amplifiers are also equipped with a ring-core transformator and HxR filtering. The amplifiers deliver high resolution dynamics, an absolut linear amplification and large power reserves.
