11946 kr incl VAT
500 series discrete class A optical compressor, side chain insert, Lundahl input & output transformers.
Description
A versatile mono compressor for 500 series frames that takes optical compression to the next level for all forms of music production. Indulge yourself in it’s smooth and creamy sound!
Control genius
You may know the sound of vintage optical compressors like the Teletronix LA2A, but often you need more control than just 2 knobs. So we present an enhanced design – the Essence – with attack & release settings carefully selected for a more varied dynamic palette plus the intelligent auto modes for that really smooth “set and forget” operation we all love. And unlike the slow LA designs, this compressor can also respond much faster when you need it. The soft knee opto action is perfect for smoothing the dynamics of vocals and a stereo pair will find immediate use to glue together stems, synths and the mix buss. And as our users report, the Essence is brilliant on bass guitar!
Audio path quality
The audio input is coupled directly to our custom made LDR (light dependant resistor) gain reduction element via a Lundahl LL1540 input transformer. This is followed by a discrete signal path using our Class A BE40 amplifier and BE50 high current line driver that excites the Lundahl LL1517 output transformer. The combination of high end Lundahl transformers with our circuits creates a very warm low end sound along with a creamy top end finish void of midrange harshness.
Creative versatility
The Essence is the only 500 series compressor (that we know of) to feature a side chain insert point so you can apply equalisation to the compression characteristic to control certain parts of the audio spectrum. The insert can also be used to “key” the compressor from another sound for all sorts of creative pumping effects. In addition, there is on board side chain shelving eq allowing you to quickly adjust the compressor sensitivity at high and low frequencies.
