Allen Heath ZED-12FX

Summary

Simplest thing that could possibly work.

Use the ¼ inch phone jack (Tip-Sleeve) outputs to

  • The Model II Analog Input.
  • Compact Channel 2
    • Set the ToneMatch® switch to Line Level
    • Set the Compact Channel 2 Volume so that with the mixer set at maximum volume levels the Compact Signal/OL light does not turn red.

Outputs

¼ Inch with suitable output

for PS1 Powerstand Channel 1 or 2 inputs

You can use TS (Tip Sleeve) unbalanced cables, or TRS (Tip Ring Sleeve) balanced cables, but since the ¼ inch phone connections at the Bose Classic and Model I Power Stand are unbalanced there is no particular benefit using balanced cables.

¼ Inch Tip-Sleeve (unbalanced) to ¼ Inch Tip-Sleeve (unbalanced)

Tip-Sleeve to Tip-Sleeve

This should work fine.

¼ Inch Tip-Ring-Sleeve (balanced) to ¼ Inch Tip-Sleeve (unbalanced)

Tip-Ring-Sleeve to Tip-Sleeve

This should work fine.

¼ Inch Tip-Ring-Sleeve (balanced) to ¼ Inch Tip-Ring-Sleeve (balanced)

Tip-Ring-Sleeve to Tip-Ring-Sleeve

This should also work, but likely no better than a simple ¼ Inch Tip-Sleeve to Tip-Sleeve cable. This is because the ¼ Inch input on the Bose System is Tip-Sleeve (unbalanced) anyway.


XLR Balanced +4

The nominal output of the XLR Balanced Outputs is too high for the XLR inputs on the PS1 Power Stand Channels 1 and 2. If you want to use balanced cables from the Mixer to Channels 1/2 on the L1 Classic or L1 Model I you may need to use a Pad to lower the signal level from the mixer.

The PS1 Power Stand (Classic) / Model I XLR inputs are designed for microphone level inputs so the +0 dBu output from this mixer is too high for optimal operation - even with the trims levels set to 0. For best results use a Pad to more closely match the output of the Allen Heath mixer with the inputs of the PS1 Power Stand (Classic) / Model I
