The new XOverWizard II software will come in two versions - a standard with nearly the same functionality as
the "old" XOverWizard and an advanced version with integrated measurement system and optimizer. The new software will
control all of our digital crossovers. Click the picture above and have a look...

Hörtest at Klang + Ton - Germany:
Ground Sound = Robert will visit Klang + Ton's Hörtest on the 21. June 2008
The A/O loudspeaker will be "activated" with our electronics (Chassis603 + Chassis1503).
The new compact CoolbackII600 will be displayed together with the development amplifier
code name OP. We will of course bring a sample of our modules and a proto type board of
the DCN28DAV. The A/O is a Wilson Watt/Puppy inspired Klang + Ton loudspeaker project
published in issue 6/2007 + 1/2008.

Coolback II 600
The Coolback II 600 will substitute both the Coolback 300 series and the "old" Coolback600 series.
The Coolback II 600 will be Ready-made for Plug and Play and it is a 3-way amplifier with our DCN23 digital crossover.
It will produce 2 x 180W (PA3CC) + 1 x 120W (PA1CC) at 8Ω.
The Coolback II 600 is 180mm wide and 600mm high - a thickness of 15mm - a flange of maximum 18mm for mounting.

Peter K's horn system
Peter bourght the amplifiers from gallery 3.
The system consists of two very big 29Hz basshorn and two 2" coax BMS 4592 ND / Horn.
Peter says:
"I do not miss any of my previous amps!"
"The sound is still clear and clean with a nice sense of ‘presence’ "
"the ‘blocks’ are VERY silent considering that the sensitivity of the speakers is +110 dB/1 watt(!) "

New products in 2008:
The PSU4DB, PSU8DB and PSU12DB has been released, which will enable our customers to build a complete High-End Stereo Amplifier
using exclusively Ground Sound products - a combination of PSUxDB, PAxCC, AmpC and transformer.
|
The PSU4DB, PSU8DB and PSU12DB has also lead to three new Stereo Power Amplifier kits:
|
In the following months we will also release four digital crossovers.
One of the new Digital Crossovers is the DCN28DAV, which have been very long time expected. It is a combination of a pre-amp and a
digital crossover cabaple of digital audio input. The digital audio input accepts PCM signals of 32kHz - 192kHz sampling rate and
16-20-24bits resolution.
The other Digital Crossovers are an enhanced version of the DCN23 called DCN24, the DCN22PRO intended for high grade active PRO
loudspeakers - the DCN22 includes clip-limiters and a lot of processing power per channel - and the last digital crossover will be
the DCN48CAR, which will be a complete 4 input / 8 output Digital Crossover for implementation in cars. DCN48CAR will include a 12V
automotive power supply and remote turn ON/OFF.
