Teknosign Sum Adjust PRO, currently at “Pre-Release” stage is the best summing amp we can make. Based on the same core of Sum Adjust Junior, it is still a 16 channels summing amplifier with much more interesting features that make it the perfect tool for both High-End studio recording, Live recording and Broadcast. In addition to the Junior, Sum Adjust PRO is equipped with 16 (2 digits 7-segments) displays above each channel that show the exact dB attenuation for each channel. It has 3 Masters (both stereo and mono), 16 XLR inputs, 2 Tascam DB25 inputs, an additional input to cascade more units and an external Master Send / Return connector where to possibly connect other devices (such as a Compressor, for example) with a dedicated push button for instant comparison of processed or not processed signals. A special Lock control has been implemented to “freeze” all knobs and buttons for a safe operation of the gear in live situations. 

The Teknosign Sum Adjust LT has the same core and the same high quality audio features of his brother Sum Adjust Junior. His goal is to satisfy even professionals with smaller budgets without having to sacrifice the quality of their mix. Therefore, to reduce costs, attenuators for the input channels have been eliminated and an attenuator is only provided for the master output. However, the possibility to link the channels in the stereo bus remains. Sum Adjust LT is therefore a summing amp with basic functions like its competitors but it has a big advantage over them. In fact, like its brother counterpart Sum Adjust “Junior” it has the digital control via VST/AAX plug-in and the ability to automate, the memory, the ease of use, the possibility of registration etc. Therefore programming and recalling settings of the bus can also be managed via a dedicated plug-in within your DAW. The Sum Adjust LT is a perfect complement to a larger machine, as the Sum Adjust Junior or other professional summing mixer.

Speck Electronics X.Sum - If you need more than simple summing, then you need the X.Sum.
The Speck Electrinics X.Sum is a 32 x 4 line mixer that can be used for external DAW summing or as a line mixer for synths, samplers, and effect returns. Any of the 16 stereo channels can be assigned to either the main stereo Mix output or the stereo Mix-B output.

Chandler Limited Mini Rack Mixer Expander - 16 Channel Expander for Mini Rack Mixer
The Expander for Chandler Limited Mini Rack Mixer allows you to expand it to 32 channels or more (with more expanders) when combined with the Chandler Limited Mini Mixer.

Together, these units make an attractive, space-saving mixer for studios that are moving from a full-size mixer to a more hybrid setup with a digital audio workstation, but still need enough channels to control your machine's outputs (DAW or tape). Each channel is transformer balanced and driven by Chandler's new Line Amplifier, which is borrowed from other Chandler products but has been redesigned for use in the mixing console and expander. Like the Mini Mixer, the Expander is filled with discrete amps and classic sounds. The unit features 20 discrete amplifiers and 22 custom wound transformers. So it delivers all the punch and tone you need in today's digital environment.

Chandler Limited's Expander mini-mixer is only an additional 16 channels of the mixing section and therefore does not contain a monitor and master control section . Contact Floating Point Audio to build your system!

Looptrotter SATUR-8/24 is the 24 channel summing unit containing 8 channels with analog saturation. The design refers to the sound of old tube mixing consoles and tape recorders.

When you need Faders but don't really need a console 
The via Fader 10M is a brand new way to connect your 500 series racks and audio gear. This product is more than just 10 slide faders.

But most importantly... no additional mixer or audio interface is required.

Purple Audio MOIYN is an all-discrete 8 channel summing amp. Only for the Purple Audio Sweet Ten.

The Moiyn makes the Sweet Ten into a 8×2 mixer.

The Moiyn only works in slot 9 of the Purple Audio Sweet Ten rack.

With the Moiyn installed into slot 9 of the Sweet Ten, slots 1 through 8 become input modules to the Moiyn. Because of the Moiyn’s differential summing input amplifiers, any standard module can be used in slot 1 through 8 with minimal loading, and without unbalancing their outputs. This means that even while you use the Moiyn to sum the outputs of the modules in slots 1 through 8, you can still take the slot 1 through 8 output XLRs to your DAW or tape machine.

The Tree Audio Stem, one of our latest products, is 8x2 channels of all discrete, Class A Inward Connections amplifiers. It's a stand alone unit that can be used with any console or just as a mixer; no need to use it with a Roots console. Pete Townshend just bought and used a Stem on the latest Who album.

The Shadow Hills Equinox is like a complete small-format recording console in just 2 rack spaces. It features 2 GAMA mic preamps, 30 channels of analog summing, and a mastering-grade monitor controller.

Finally, with the Teknosign SUM ADJUST CLASSIC summing mixer, you will have a true out of the box mixing power in your Digital Audio Workstation (DAW). You will be able to mix like in the best recording studios with the possibility of adjusting the relation between the various channels in an impeccable way.

The result will simply be the greatest sound you have ever experienced.

BURL AUDIO introduces its latest hot bed of creativity, the B32 VANCOUVER NextGen, a 32 channel mix bus.

Purple Audio MFTwenty5 is a rack mount discrete summing mixer designed for the 500 series modules and racks. The MFTwenty is a central hub connection other components (fader pack, Vu meters, 500 series racks and modules) to offer an analog modular console. The MFTwenty5 brings new use and value to your 500 racks & modules. Several MFTwenty units can be chained for larger systems. Four fader packs are offered. The optional fader pack and meter can also operate in standalone, without the MFTwenty5.

Undertone Audio Pyra-Sum is a passive summing mixer that has what other summing mixers don't: multiple cascading busses. This bussing architecture allows you to truly have the sound and workflow of a large format console but with even more sonic flexibility and in a much smaller format. We've left out any active circuitry, which means that you have total control of the coloration that's added in the makeup gain stages—it also means you'll need to use this with eight of your own 19" or 500 Series preamps. Want a different sound? Swap the preamps. You could use dedicated preamps for that 70s sound. Tube preamps for that 50s sound.  UTA preamps for a size and musicality that has never existed before.  Or, since the preamps are inserted after each stage of summing, you can mix and match— dedicated preamps on the drums, UTA preamps on the music, and nother type of mic pres on the vocals ... etc. The sonic possibilities are endless.

• Four discrete stereo summing busses
• Recreate the bussing architecture of a large format console
• Incorporate the sound and color of any mic preamps you choose
• All passive circuitry
• Make better use of all your favorite outboard gear
• Make Pyra-Sum the heart of your ultimate hybrid mixing setup

Like his fellow companion Sum Adjust Classic, Teknosign Sum Adjust Junior is a pure analog summing mixer, but offering digital commands. It shares the same high-quality audio core circuits and great heritage of the past, giving you the best analog sound. However, the Junior is inspired to the great Total Recall consoles of the mid 80’s that were also able to store the global setting of the machines.
