8 Tracker Meter Bridge

The 8 Tracker attempts to squeeze a lot of functionality into a small space. The larger part of the mixer is taken up with the 8 channel amps and their faders. All the other functions of the mixer need to be contained in the 3U meter bridge running along the top. Here is a suggested layout for the 3U top sub-rack:

There is no room for a master slider fader so a large rotary knob is used instead. As I am right handed I have placed this in the right most module of the meter bridge. This module also contains a Twin Line Amp (TLA) that provides the mix bus amplifiers for the master left and right outputs. Another TLA is used for the AUX mix bus amplifiers. This is shown at the far left of the meter bridge. Next to the AUX sends are the four direct inputs housed in two modules. Each module uses one TLA which can handle two direct inuts. On the right, next to the master fader, is another TLA which provides the PFL bus and the talkback amplifiers. This leaves just three slot widths in which to house the meters and monitor section. A Sifam AL29SQ meter will fit in one module width with enough room below for its switching so the two central module spaces are used for the meters. This leaves one slot to the right of the meters for the monitor section. As there is a lot of cabling behind the meter and monitor panels and some of it is interconnected, it probably makes sense to combine these into a single three module wide panel. The monitor panel will probably need its own small board to accommodate the 10K:600 monitor isolation transformers.
