Fusion Processing

Transformer

Fusion features a custom-designed SSL TRANSFORMER circuit, which is engaged via the front panel transformer
switch. This circuit does a number of things: The 600Ω, 1:1 winding transformer and surrounding circuitry adds low-
end harmonic content and a favourable slight top-end phase-shift to the sound. Furthermore, the underdamping
of the transformer adds a subtle 'weight' to the sound. It is worth noting that the drive of the transformer circuit is
self-contained, so there is no advantage in driving the Input stage of Fusion to achieve more level through the transformer.
Also, as is inherent with transformer designs, extreme low-end frequencies begin to be rolled off, the more level is put through
- so bear this in mind. Typically, a level of +16dBu will see a 0.5dB roll off between 40Hz and 30Hz and this is quite often (but
not always!) welcome in keeping the bottom-end in check. Experiment with engaging the transformer at any point during the
mixing process to see if it makes the mix sound better (it often does).
