4 Th e Kultube is an e x trem ely vers atile compres sor wi th a broad r ange of control f acili ties that cover all t ypic al compressor applic ations . From improved ste reo m ixes in the “MIDI Studio “ to surround mas tering with s everal dev ices connec ted, all jobs c an be under taken to the hi ghe st deg ree of sound qualit y .
5 Car eful ly se lect a place for set ting up the Kultube. T he unit should be situated away f rom heat s ources and direc t sunlig ht. Avoid inst allation in env ironment s expos ed t o vi br ations , dust , heat , cold or moisture.

8 Sidec hain inp ut s Thi s ja ck i s used as a s i dechain input for connec ting an e x ternal audio sig nal to con t rol th e Kultube (e. g. an equalizer for f requenc y dependent proce ssing ). It is conf ig ured as a s tereo RC A jack , wi th the lef t channel on the tip and the righ t cha n nel on the ring.

RED / V U Thi s swit ch cha n ges the VU met e r over to Gain R e duct ion mode. Th e indicator needle then jumps to the 0 dB value and moves to the lef t with increasing compression.

12 TUBE HARM ONICS The TU BE HARM O NICS cont rol allows you to dr ive the tub e output s tage inf i- nitely variable to desperat ion: the more the cont rol is tur ned in, the f ur ther the tube get s into sa turation and the more har monic s are produced.
13 The R atio c ontrol As in d i ca t ed a bo v e, t hi s determine s the ratio b et ween the in - and output level above the threshold s et ting. T he pres et value specif ies how the input dynamics sh ould behav e wi th resp ec t to the output: a ratio of 1 to 2 means that only half of t he dy nami c c h ang e wi ll b e p r esent on the output.
14 Operating Understanding and enjo ying the Kultube In the lat ter ca se the r atio changes depending on the in 0ut sig nal. A s the preset t hreshold v alue is approached the r atio is compar ati vely small (1: 1 . 5) and doesn’t reach the preset ma ximum value until high input le vels are present .
15 Proc essed in this way , dr ums ge t more s elf ass er t ion and sound ‚f a ster ’ . The be st settin g is not alw ays ea sy to f ind, since you usually need to f ind a compromise.
