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. Each fader channel has the necessary input and output electronics to allow the via Fader to interface to any balanced, unbalanced, transformer, or transformer-less line level signal. But most importantly... no additional mixer or audio interface is required.

The via Fader 16M is a brand new way to connect your 500 series racks and audio gear. This product is more than just 16 slide faders. Each fader channel has the necessary input and output electronics to allow the via Fader to interface to any balanced, unbalanced, transformer, or transformer-less line level signal. But most importantly... no additional mixer or audio interface is required.

With its clean, uncluttered layout, Speck Via Fader 16M can be placed in a convenient desktop location or installed in your 19" rack. This gives you more choices when it comes to the studio layout. Not exclusively for 500 rack systems, the Via Fader 16M can be used for external DAW summing or as a line mixer for synths and samplers. In many cases, the Via Fader 16M can eliminate the need for a mixing console in your studio. The four Via Fader models give you lots of possibilities.

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.

Kahayan EPSILON II 24 channels analog summing mixer with Unique analog with 3 distinct systems of summing, all in one.

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.

Henry Engineering StereoMixer is an 8-input, 2-output stereo mixer for line level sources. It is an ideal utility mixer that can be used to combine 4 stereo or 8 monaural sources. StereoMixer can produce either a stereo or mono output, selected by the Output Mode switch. In Stereo mode, 4 stereo sources are combined to a stereo output. In Mono mode, all 8 inputs are combined to a mono output. Each input will accept either a balanced or unbalanced source.

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.

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. 

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.

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.

BURL AUDIO introduces its latest hot bed of creativity, the B32 VANCOUVER NextGen, a 32 channel mix bus. Based on BURL AUDIO’s renowned discrete analog, class-A circuitry, the B32 mix bus employs both the transparency of the B26 ORCA, plus the switchable tonality of the new BURL AUDIO BX5 output transformer.

In addition to the BX5, the B32 VANCOUVER introduces a new concept to the summing amplifier, GAIN BOOST. Adding gain boost with the BX5 will give your mixes that glue that you have been seeking ever since retiring your 2-track analog recorder. With 32 input channels and switchable tonality, the B32 VANCOUVER will allow your mixes to thrive in depth, warmth and clarity. Use the B32 VANCOUVER in conjunction with the B1 MIC PREs, the B80 MOTHERSHIP and the B26 ORCA and you will achieve THE COMPLETE SOLUTION.

Henry Engineering  MicroMixer is a 4-input, 2-output stereo mixer for line-level sources. MicroMixer is a perfect utility mixer with numerous uses: combining 2 stereo sources to a stereo output; combining up to 4 mono sources; mixing mono and stereo sources to a stereo output. Each balanced bridging input will accept a balanced or unbalanced source.

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.

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!

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
