Three different ToolMod Frames are available. The small, 1U high, rack-mounted ToolMod frame can house up to five modules. The variable subdivision with removable spacers allows using 2U and 4U modules as well. Each frame compartment can be used for mono or stereo modules. All necessary connectors are installed. The modules are installed horizontally.

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.

SpacerToolMod 1HE SpacerModule Compartments
There are five module compartments in total in the 1U high ToolMod frame. The standard version comes with two spacers. Up to four spacers are possible. With 4 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.

This principle offers very high flexibility, since the 1U high frame can be used for any combination of modules on the fly.

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. The pictures to the right show the TM101 transformer Mic-Pre in both, horizontal and vertical versions.


Rear View of the 1U-high ToolMod FrameRear Panel of the 1U-high ToolMod Frame

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 mono modules. The two additional TRS connectors are used differently, depending on the module. With 2U format stereo module, the TRS connectors are used for the input and output of the right channel. The connector assignment of a particular module can be found as a link 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.
