✪When connecting audio cables and/or turning power on and off, make sure that all devices in your system are turned off and the volume controls are turned down.

Connecting to the Channel Inserts of a mixing console:

Unbalanced I/O

Most recording consoles have a jack near the mic and line inputs labeled "Insert". This is typically a TRS jack with the send and return on the same jack. To use the PEQ-450 as a channel insert, you will need an insert cable (not included).

		Insert Send:
		To EQ Input
	Ring:
	Insert Return
Tip:	Sleeve:
Insert Send	Sleeve:	Insert Return:
	Insert Ground	From EQ
		Output

This cable splits the TRS insert jack into two unbalanced mono connectors. Usually, the tip is connected to the INPUT of the equalizer and the ring is connected to the OUTPUT of the equalizer. However, this may be reversed on some recording consoles. Check your mixer’s Reference Manual to be sure or just try it both ways – this won’t damage the PEQ-450.
