Drawmer Three-Sum Multi-Band Split & Sum Device
Enables Individual Processing of up to Three Bands Prior to Re-Summing

The benefits of multi-band processing, with the ability to apply different parameters to different sections
of the audio bandwidth have been apparent to sound engineers for quite some time.
However, 'locking in' your audio to any one specific multi-band unit can vastly reduce the creative
options. The desired combination of processing to deal with low frequency energy, the vocal mid range
and high frequency detail and enhancement is not necessarily available from any one manufacturer.
The new Drawmer THREE-SUM opens up a whole new set of options allowing the engineer to split
the audio into two or three bands and apply his or her own sonic signature to each part of the audio
bandwidth.
The THREE-SUM employs a high quality signal path culminating in a variable threshold, brick wall
limiter section with bypass facility. To ensure transparency the limiter design is 'two stage', applying
different processing to the H.F. content of the material. In applications where the dynamics of the
material need to be retained to create an open sound, the limiter is essential for catching peaks.
The THREE-SUM has been designed for use in high-end mastering and general recording
applications, alternatively, it can transform a project studio, equipped only with 'single band'
processors, into a serious multi-band facility.
