788T Input and Track Relationship – v 1.60

With revision 1.60 firmware for the 788T,  the unit has gained four record tracks, for a total of twelve. Each of the eight 788T inputs can be routed to any of the twelve tracks in limitless combination.

The diagram below illustrates the routing possibilities of the 788T.


788T inputs are physical connections, selected from three signal types:

  • mic-level signals, analog (with or without phantom)
  • line-level signals, analog (with or without phantom)
  • AES3 or AES42 digital signals (AES42 power available)

The 788T has eight inputs, and each of the eight inputs can be routed to any of twelve tracks. Assigning inputs to tracks is done from the Input Settings Window.

By toggling any of the eight input switches, the Input Settings Window for that associated input appears on the LCD (Input 1 shown below). The display below highlights the section of the Input Setup Window showing input routing. In this example, Input 1 is routed to the following tracks: L, A, B, C, D, E, F, Aux1, and Aux2.

To route inputs to tracks, pressing the Play button brings up the Input Routing Menu shown below.

Remember that each of the eight inputs can be assigned to any of the twelve tracks.

The video below shows a brief overview of input-to-track routing.


With inputs routed to tracks, tracks can recorded, and/or used as output buses. For tracks to be recorded, they must be “armed” for recording. Track arming is done in the Track Setup Menu. Access the Track Setup Menu (shown below) by pressing the front panel INPUT button.

A track is armed and ready to record when an asterisk is shown next to the track name. The Track Setup Menu also indicates levels at each of the twelve tracks at a glance. The front-panel blue LED’s also show the status of track arming.

Tracks are either pre-fader, post-fader, or both, depending on the track.

  • Tracks A – H, pre-fade only
  • Tracks L, R, post-fade only
  • Tracks Aux1, Aux2, pre- or post-fader

Typical applications for tracks A-H are for isolated recording of the eight inputs.

Left and Right Tracks

Left and right tracks L and R are commonly used to assign multiple inputs for a mix, either mono or stereo. When using the CL-8 with the 788T, the fader controls on the CL-8 control the level of each input sent to any post-fade tracks, chiefly the L and R tracks. The combination of the CL-8 and the 788T makes for a powerful, flexible mixer setup.

Since there is no dedicated master level control on the CL-8, a Master Gain Menu is available by pressing the Play button (below “Levels”) while in the Track Setup Menu. The Master Gain Menu is shown below.

The levels of the L and R track, as well as the Aux1 and Aux2 tracks can be viewed and controlled from the Master Gain menu.

The video below shows how tracks are armed and the control of master levels.

Tracks as Buses

Because of the routing flexibility of the 788T, complex cart-based setups can be built. Whether or not a track is armed to record has no effect on its ability to be used as a source for any of the six physical outputs on the 788T. An example of why this is useful is shown with the example below.

Input assignments as follows:

  • Input 1 – boom, main mic
  • Input 2 – boom
  • Input 3 – lav
  • Input 4 – lav

Track assignments as follows:

  • Input 1 to A for iso track recording
  • Input 2 to B for iso track recording
  • Input 3 to C for iso track recording
  • Input 4 to D for iso track recording
  • Inputs 1, 2, 3, 4 to L for a mono mixed track recording
  • Input 1 to  Aux1 to feed a camera input (L) with main boom
  • Inputs 2, 3, 4 to Aux2 to feed a camera input (R) with other input signals

Output Assignments as follows:

  • Aux1 to output-1
  • Aux2 to output-2

In this example, tracks Aux1 and Aux2 are used exclusively as signal buses to provide a feed to to the camera for a backup recording.
