The DiGiCo SD9 is the entry-point to the SD ecosystem — 48 inputs, 16 outputs, single 15" touchscreen, and one MADI port (with an optical option slot for redundancy). It earned a reputation as the "right-sized" console for regional theater, mid-size touring, and worship gigs that wanted DiGiCo reliability without paying SD12 prices. Discontinued by DiGiCo but still extremely common on rental inventories and used markets.

It sits squarely in the territory where regional theater, mid-size touring, and larger fixed-install worship programs need real mixing horsepower without the footprint or price of an SD12.

For the right show size and budget, the SD9 is a proven, forgiving workhorse.

X32 RackThe Behringer X32 Rack packs a full-featured 40-input digital mixer into a 3U rack-mount form factor, making it a popular choice for IEM mixing and playback rigs on a budget. It can serve as both a monitor mixer and a USB audio interface simultaneously, and optional expansion cards add Dante networking or additional digital I/O. The deep bus structure with 25 mix buses means you can create individual IEM mixes for a full band without running out of routing options.View gear →
X32The full-size Behringer X32 brings 32 Midas-designed mic preamps and 16 XLR outputs onto the console itself, eliminating the need for a stage box on small-to-mid stages. Two AES50 ports still let you hang DL or S-series stage boxes when the rig grows. The 25-bus engine delivers a healthy supply of independent IEM mixes, and Ultranet runs to P-16 personal mixers off a single Cat5 to the stage. A long-running workhorse of monitor world for budget-conscious productions.View gear →
M32R LiveThe Midas M32R Live is the rack-mountable, 16-fader sibling of the flagship M32 console. It brings 16 fully-featured Midas mic preamps, a 40-input mix engine, and two AES50 ports that let you hang Midas DL-series or Behringer S-series stage boxes off a single shielded Cat5e per link — up to 48 channels over one cable. If the rig has a DL16/DL32 or S16/S32 at the stage, the AES50 trunk is the connection back to this console; local XLR inputs on the console itself are reserved for last-minute stage-side patches.View gear →
