Tiptop Audio MIXZ
MIXZ is a low-cost, analog multi-channel mixing module for mixing audio, CV and gate signals with excellent linear response and low noise. Balancing a clear visual layout and multiple mixers in a small footprint makes the MIXZ easy to use in a variety of configurations within the modular synth. Its high quality analog mixing circuitry makes for a great sounding mixer with plenty of headroom, providing a smooth organic merge of dynamics, and excellent separation of mixing sections and channels. MIXZ has three sections:
Mixer A - a low-noise, 4-channel mixer with independent gain control for each channel
Mixer B - a low-noise, 4-channel mixer with master gain control
Bus Mix - a multi-channel mixer that mixes signals from modules utilizing the Tiptop Bus Mix
Mixer A and B ca be configured as either two independent 4-channel mixers or as a single 8-channel mixer. If the output of Mixer A is not in use, then Mixer A will be routed internally to Mixer B forming the 8-channel mixer.
Tiptop Bus Mix is a new method we have developed to mix audio signals through the Eurorack power bus board without patch cables, a little bit of magic, eh? Although this technique is not ideal for a low-noise mix, we found it to be useful for some applications including mixing our drum modules, which all have a Bus Mix enabled output. The result is that your drum modules are always available and mixed on the master out of the MIXZ with a flip of a switch. This will ave you time and frees up cables for repatching sounds again and again, while keeping the channels of MIXZ free to bring other signals into the mix.
Combining the Bus Mix with Mixer A and B, the MIXZ can sum dozens of channels in only 10HP.
