TC Electronic Massenburg Design Works Hi-Res EQ

The license includes two equalizers. One for dual mono and stereo, one for 5.1 or 6.0. Both can be used at sample rates between 44.1 and 96 kHz.

Massenburg DesignWorks® HiRes EQ
In recognition of George Massenburg's great sense of audio and strong influence on previous TC processors, the new MDW® HiRes EQ has been developed. The MDW® design complements the TC alternatives and therefore offers the user a choice between several desirable EQ flavors, each with specific advantages.

The combination of System 6000 and MDW® HiRes EQ constitutes a 48 bit precision signal path from Input to Output. It comes in 2 and 6 channel configurations with flexible linking and absolute/relative real-time adjustment properties. The 6-channel version features 6 identical processing channels making it equally suitable for controlling 5.1 and 6.0 signals.

If the System rate is set at 44.1 or 48kHz, the signal is up-sampled to double rate, processed and down-sampled to System rate. This approach is one way of mimicking more precisely the behavior of analog EQs plus reducing alias distortion. The EQ can also be operated at 88.2 or 96kHz. At high System rates, up/down sampling is bypassed, providing a bit transparent signal path at unity gain.

The EQs feature 5 parametric bands per channel. Outer bands can be configured as shelving or 2nd order filters (Butterworth). Band 1 filters can be switched between 2nd and 4th order. All five bands cover the complete frequency range. Each parametric or shelving band is capable of cut/boost over a +/-25 dB range."
