The Ditto range of line level mixers offer multiple independent line mixers in compact 1u or 2u subracks. Where multiple talkback channels need to be mixed, or any number of
multiple sources need to be mixed, the Ditto units are a simple and cost effective choice. A typical use would be in outside broadcast or in studios for talk back mixing.
Every unit has the option of adding front panel patch points via 6.35mm jack sockets. There is one under each input and connects in parallel with the main rear input. There is also a jack socket under the output control for monitoring of the output mix.
There are two factory options with the ‘J’ Versions.
1. Inputs are in parallel with the rear inputs (Standard)
2. Inputs are break jacks and replace the rear inputs (add ‘B’ suffix)
