ISO-3 Isolator

Currently building to order with a 4-5 week lead time from placing order.

3-way operation with optional plug-in cross-over points, internal phono preamp input and internal trim control.

The Bozak ISO-3 uses high performance analogue tone control circuits using individually selected discrete components that isolate the signal into three bands.

The level of each band is controlled independently and Bozak’s frequency dividing technology provides superior dynamic response making the control smooth, predictable and ultra controllable.

The individual tone control allows the user to isolate beats, vocals and high hats as well as adjusting the overall tonal quality.
The cross-over points have been carefully selected to yield a very natural sound and to emphasise the artistry in the musical production.

Bozak’s overall frequency response is second to none, we do not use low or high pass filtering in our circuits so you hear and feel the full sub and high frequencies.

Fitted with ALPS RK27 Blue Velvet pots, carbon resistors, polyester mylar capacitors and ultra low noise hi-fi grade worldwide toroidal power transformer, all culminating in Bozaks signature rich warm sound.

The ISO-3 is fitted with a phono pre-amp switched internally for direct connection of a turntable plus a trim control to balance the input to output signal to match up the ISo-3 with any mixer.
