SPL Reducer small Reducer – The new passive Power Soak from SPL and TonehunterIn addition to our active TRANSDUCER and CABULATOR versions with speaker simulation —which you surely know or have heard of— we have now launched the REDUCER, a purely passive power attenuator for guitar amps.

The product is very easily explained: as the name implies (we had to think really hard for this one..!), it reduces the power output of the guitar amp. This means that all sorts of amps, especially tube amps, can now be overdriven without the need of having to be too loud. Your neighbors are gonna love us  :-)

ProfessionalAudioMag 12 2010 The Transpressor passes the Professional Audio test

Professional Audio magazine reviewed our Transpressor in their December 2010 issue. Georg Berger called it the “Dynamic Duo.” He liked specially the “wonderfully organic analog sound” and the “brilliant Auto function in the compressor section.” But that’s not everything by far:

“Both dynamic sections have excellent audio properties and the shaping possibilities they offer make them very appealing. The Transpressor works best when both sections interact. It really doesn’t matter if you have the Transient Designer before or after the compressor in the signal path, the possibilities to shape sound are endless. We can give more punch to over-compressed signals by emphasizing the attack with the Transient Designer. Or, the other way around, we can control a very aggressive guitar by smoothing out its attack and then make it bigger with the compressor: in the end we would have a wonderful flat sounding and cutting guitar. These are only two of the countless options available — we wouldn’t have enough space in this review to even start to mention them all.”

A closer look at the Frontliner

Jens1 300x251 A closer look at the FrontlinerOn the 15th of May, 2010, we visited Jens from our Hardware Department. He is giving right now the finishing touches to the Transpressor, his latest baby, which made its debut at this year’s Musikmesse. The unit tested by the visitors to our stand last March was only a prototype of the Transpressor. Like all of them could see, it was perfectly functional. But Jens is a perfectionist, so he wanted to recheck some minor details regarding the circuit and the layout of the circuit board before the unit went into production.

However, before the Transpressor came, Jens used to spend all his time with the Frontliner. It took him one whole year to get it the way he wanted it to be (from concept to actual production). Even though we know he is always really busy, we decided to meet up with him so he could tell us some of the secrets behind the Frontliner. And he was more than happy to welcome us…!
