Connection and SetupRequired Cable:
Use a standard TRS "Y" Insert Cable.
TRS Tip: Sends the signal to the external processor.
TRS Ring: Returns the processed signal back to the mixer.
Routing: Assign individual channels to a subgroup (e.g., Sub 1-2) using the assignment buttons next to the channel faders. Use the Pan control to send the signal to either the odd or even subgroup in a pai

Key Features of Subgroup Inserts

Signal Path Location: These inserts are located before the subgroup faders. This means moving the fader will not affect the signal level being sent to your external processor, which is critical for maintaining consistent threshold levels on devices like compressors.

Dual-Functionality (Direct Outs): On many Mackie models, including the 32-channel VLZ series, these insert jacks can also double as Direct Outs. By inserting a mono 1/4" plug only to the "first click," you can tap the signal without interrupting the signal flow to the main mix.

Onboard Integration: In addition to physical inserts, the 3204VLZ4 features dedicated inline compressors on each of the four subgroups. This allows for smooth dynamic control of grouped signals, like a drum kit or a choir, without needing external hardware
