group connectors- rear panel

The HPW group output connections are located on the Master rear output panel. Each group features a 1/4” TRS output connector, along with a 1/4” TRS Insert connector. The output is a ground-compensated, impedance-balanced TRS jack. For wiring purposes, treat this connector exactly like a balanced output. When connected to an unbalanced input, the ground-compensation circuitry will act to reduce the ground-signal differences between the console and the remote gear.

The TRS Insert jack is wired as Tip=Send, Ring=Return, Sleeve= Audio Ground. This is the “industry-standard” wiring scheme for most single-jack inserts.The Insert send-point is located directly after the group mix amp, the Insert return feeds the top of the group fader, or the top of the level pot if Fader-Reverse is active (see Block Diagram).

47group output 1/4"TRS jack

The group output signal is available at this output jack.The output jack is impedance- balanced, ground-compensated.

Tip is +Drive, Ring is -Drive Return, Sleeve is Chassis Ground Send (Drive) impedance is 50Ω

Ring impedance is 50Ω to Audio Ground

Nominal Operating Level= +4dBu

Max Output Level= +21dBu (into 2kΩ or higher)

48insert jack 1/4"TRS jack

This switching 1/4” TRS jack allows an external signal processor to be inserted into the signal path of the group.The tip carries the SEND signal from the group, and the ring car- ries the RETURN signal back to the group.The Insert-Send point is located directly after the group mix amp, the Return comes back at the top of the group level control.

Tip is Send, Ring is Return, Sleeve is Audio Ground. Send (output) impedance is 50Ω

Return (input) impedance is 5KΩ Nominal Operating Level= -2dBu

NOTE: To avoid any degradation of the HPW’s group signal, any processing gear patched into the group insert jack should have a low impedance output (<100Ω) and must be capable of cleanly driving a 2KΩ load to +21dBu.

The

not change

the function

of any of the rear-panel

jacks. The

and Insert jacks are always

located

here. Similarly, the

Aux Output and Insert jacks

always

retain their same

function.
