WHAT DOES AN AUDIO MIXER DO?

While a digital system rounds off all values for level, pan, eq-ing and compression, the analog summing technique operates with an infinitely high resolution, causing no rounding errors or digital distortions. The analog domain offers a number of great advantages compared to the simple “DAW bounce-function”.

Why analog summing mixer?

Summing mixer is simply combining DAW, Synth, or Drum machine output signals. The idea of a summing mixer is that you feed it multiple analogue audio signals, eg. outputs of your audio interface, synth or drum machines which are then combined (i.e. summed) in the analogue domain.

What exactly does a summing mixer box?

Beside of combining signals, It provides Headroom — buffer safe zone for harmonics, transients or loud sounds without risking clipping, which result a more dynamic open and wide, depth 3D sound, just like the good old analog days.

Basically, instead of having your tracks merged digitally into a stereo mix in your DAW, you run each track individually out to the analog summing mixer and do it all there, then bring it back into your DAW

Analogue — analog summing boxes have their uses beyond simply combining (sum) signals. Features like Mono option per channel for mono instruments like kick basss and master‑bus insert send return points, for example, can be extremely useful, as they provide an easy way to incorporate outboard hardware (EQs, compressors and the like) into your rig.

D-Sub DB25 Tascam Standard Analog Balanced

TASCAM developed the standard for multi-pin DB-25 cables over 10 years ago, and most of the pro audio industry has followed this standard. This is the pinout found on TASCAM mixers, recorders and their accessories.

Be sure you’re using Analog DB-25 — NOT (AES/EBU digital)!

process of “Brauerizing”; Multi-Bus Compression, Multi-Vocal Compression
“Brauerizing” is the name given to a mixing mentality honed by Grammy award winning mixing engineer Michael Brauer, feeding audio into compressors and equalizers in order to impart harmonic content to the input signal, as well as utilizing subtle group compression to “glue” audio together through an audio phenomena known as “counter pumping”

Balanced audio is a method of interconnecting audio equipment using balanced lines. This type of connection is very important in sound recording and production because it allows the use of long cables while reducing susceptibility to external noise caused by electromagnetic interference.

XLR balanced pinout: 1=GND, 2=hot (+), 3=cold (-)

The XLR connector is a style of electrical connector, primarily found on professional audio, video, and stage lighting equipment. The connectors are circular in design and have between three and seven pins. They are most commonly associated with balanced audio interconnection, including AES3 digital audio, but are also used for lighting control, low-voltage power supplies, and other applications.
