Kaatskit Radio Company

All of our consoles are modular, using “quad-modules”, four inputs in a module. Combining in groups of four provides most of the advantages of a fully modular design at a lower cost and smaller size.

Here are three, in 3 different sizes.

The small one is simple. 8 faders, full monitor, the basic input module. The big one meets the needs of most … 16 faders, the complete input module. The one in the middle is a good fit for a small studio … 12 faders, the complete input module.

Mainframes are available in sizes from 2 bays (8 faders max, or 4 faders with monitor) up to 8 bays (32 faders max, or 28 with monitor).

We offer three types of input modules:

• A “3-bus” module, comparable to what you get with the best analog consoles. There are three stereo buses, “Program”, “Audition”, and “Utility”. Each has two stereo inputs (A/B) with separate gain trims.

• A simple “basic” module, for simpler applications and lower cost. It really has 3 buses. There are no bus assign switches, keeping it simple. You assign the buses with jumper plugs on the back, so it is sort of a permanent configuration. It's the same as the 3-bus module except that some parts, mostly switches, are left out to reduce the cost and complexity.

• An even simpler “unbalanced” version. This is the same as the “basic”, except that there is no input buffer and no gain trim. The gain is fixed, for ”-10 dBv” for most consumer devices. It also uses the less expensive “thin” style faders. It keeps the cost down.

All modules are the same size, and are interchangeable. As you would expect on any real broadcast board, all have “cue”, “talkback”, and remote starts. Connections are RJ-45 jacks, fully “Studiohub+” compatible, including power.

Our main product is console kits, but we do also offer fully assembled consoles.

To save you more money, and to give you more flexibility, you can buy “a-la-carte”. That way you can make little mixers, submixers, and other things we didn't think of.
