TOMO Audiolabs Lisa is a stereo 6 band Eq with dynamics processing on each band. With two shelf bands and four parametric bands - (two parametric bands can additionally be switched over to shelf), as well as low-cut and a M/S matrix, the parallel-structured compression EQ offers unlimited flexibility. The LISA is a mixing and mastering engineer's dream come through.
The most unique feature of the LISA is that the processing is done in parallel.
From the manual:
"The signal is then split into six parallel channels that feed the six independent equalizer bands. After each signal is processed independently, all six channels are then summed up and amplified. The output stage is also transformer coupled and gives the user the ability to mix the processed signal with the unprocessed or dry signal.
Our parallel topology allows parallel processing (two bands at nearly the same frequency) without the issues of interacting frequency curves. This keeps the processed signal very transparent, consistent and controllable. The results stay predictable, helping you to work very quickly and with an experienced touch.
Traditionally designed dynamic equalizers utilize a dynamic processor that is arranged before or after the filter circuit. Part of what makes the design of LISA’s dynamic processor so unique is that it is built into the filter circuit. This allows the user to listen to only the processed signal without any of the dry signal."
• Six frequency bands with a broad frequency
overlap provide optimum processing flexibility
• Each band is equipped with the parameters gain,
frequency, threshold, and six presets for selection
of attack/release behaviour. In addition, the four
mid-range bands have a five-stage quality selection
from 0.4 to 5. Both the second and fifth band
can optionally be used as shelving or bell filters.
The two edge bands (boost) can be switched
between a variant with overshoot and a variant
without overshoot. The four mid-range bands are
configured as boost/cut filters.
• Particular processing versatility thanks to a
parallel circuit concept (mixing console principle)
• Dynamic processing is a component of the filter.
Unlike conventional designs, dynamic processing
is not downstream from the filter; instead,
dynamic processing is integrated in the filter.
• Active filter concept with the tonal attributes
of a passive filter
• Low-cut that is particularly free of colouration
can be switched in 11 positions between 20 and
180 Hz. Filter slope increases dynamically from
12 dB/octave to 18 DB/octave at lower cutoff
• The use of special and, uncompromisingly, the
best components for achieving the highest quality
• Newly-developed transformer concept gives
LISA the ability to render subtle tonal gradations
that surpass those of the leading transformers
on the market
• Additional analogue tone variation thanks to
specific saturation of the input transformers
• Extensive dynamic range of 122 dB and
overload resistance thanks to high operating
voltage (output level + 28 dBU)
• M/S matrix
• Output section permits gain-adapted A/B
• A control function permits solo auditing of
the processing path
• Lock switches with easy-to-reproduce settings
• Ergonomically structured and intuitive user
interface with attractive haptics (tactile feedback) and backlighting which makes for a short learning curve
