TUBEULTRA-Q
Ultra-musical 4-band Tube Parametric Equalizer delivers outstanding equalization both in live applications and in the studio
sFor gentle contouring and audio sweetening in audio post-production and recording studios
sFor room equalization and extreme corrective surgery e.g. notching out unwanted frequencies
sOurnewULTRATUBEcircuitrywarmsupyourmusicwithoutunwantednoise
sA special “Warmth” control lets you add the amount of tube sound you want

sEach band is switchable in/out and is fully adjustable from extremely narrow notch filter (0.03 octave) to
broadbandequalization (2 octaves)
sA wide overlap between frequency bands allows for extreme cut or boost
sAdditional sweepable High and Low Cut filters remove unwanted frequencies e.g. floor rumble and tape
hiss
