The 1U high Frame is the standard frame for almost every application and setup. Channel Strips, Stereo Mastering Sets, Processing Units, M/S Microphone Preamps and a lot more are possible in a single 1U high frame that offers a very flexible solution at an affordable prices. The 2U high and 4U high frames can be used alternatively. These larger frames are of advantage, if a ToolMod system consists of many modules.

Module Compartments
There are five module compartments in total in the 1U high ToolMod frame. The standard version has four spacers. Five size 2U modules can be installed. The spacers are fixed between top cover and bottom cover with Philips head screws and can be removed or installed easily, without disassembling the frame. If a spacer is removed, size 4U modules can be installed in two adjacent compartments. This principle offers very high flexibility, since the 1U high frame can be used for any combination of modules on the fly.

The modules are fixed with knurled screws that are used as handle when removing or installing modules. Knurled screws and blind panels are available as Accessories.

The pictures show a 1U high frame with removed top cover with three 2U and one 4U modules. The picture on the left side shows a partly removed 2U module.

Module Versions
The 1U high ToolMod frames are designed for modules with horizontal faceplates. The only difference between horizontal and vertical modules is the orientation of the lettering and the control knobs. Modules with vertical faceplates can be installed in 1U high frames and are fully functional. The lettering is simply rotated in this case.

Connectors
The four audio connectors for each of the five module slots are installed on the rear panel. The female XLR connector is usually used as audio input, while the male XLR connector is the output of most of the modules. The two additional TRS connectors are used differently, depending on the module. The connector assignment of a particular module can be found on the module web pages. Here is the assignment of the Connectors of the TM101 Mic Pre as an example. 4U modules are installed in two module slots, which means that there are two complete connector sets per module. Stereo modules in 4U size always use the XLR connectors for the main inputs and outputs.

The female and the male 5-pin XLR connector for the power supply are internally connected in parallel. The power supply system uses the 'daisy chain' principle; power is connected from frame to frame. Information in detail on the power supply units can be found on the ToolPwr Power Supply Units web pages.
