Mackie Onyx 80 Rear Panel, 67. MIC Input, 68. LINE Input, 69. INSERT

Rear Panel

This is where all the connections are made to the Onyx 80 Series (except the headphones and lamps).

67. MIC Input

This is a female XLR connector, which accepts a balanced microphone input from almost any type of micro- phone. The microphone preamps feature our new Onyx design, with higher ﬁdelity and headroom rivaling any standalone mic preamp on the market today.

The XLR inputs are wired as follows:

Pin 1 = Shield or ground

Pin 2 = Positive (+ or hot)

Pin 3 = Negative (– or cold)

68. LINE Input

This is a 1/4" TRS connector, which accepts a balanced or unbalanced line-level input signal from almost any source.

When connecting a balanced signal to the LINE inputs, wire them as follows:

Tip = Positive (+ or hot) Ring = Negative (– or cold) Sleeve = Shield or ground

When connecting an unbalanced signal, wire them as follows:

Tip = Positive (+ or hot) Sleeve = Shield or ground

69. INSERT

These 1/4" TRS jacks provide a send and return point for each channel. Use the INSERT jacks to connect serial effects devices such as compressors, equalizers, de-essers, or ﬁlters to each individual channel.

The INSERT points are after the GAIN, Polarity, and Low Cut controls, but before the EQ and Fader controls. The send (tip) is low-impedance, capable of driving any device. The return (ring) is high-impedance and can be driven by almost any device.

Special insert cables are available, specially designed for this kind of insert jack. They are wired as follows:

	ring		SEND to processor
tip		(TRS plug)	“from tip”
	sleeve
this plug connects to one of the			“to ring”
mixer’s Channel Insert jacks.
			RETURN from processor

Tip = Send (output to effects device) Ring = Return ( input from effects device) Sleeve = Common ground (connect shield to all three sleeves)

Besides being used for inserting external devices, these jacks can also be used as channel direct outputs; post-GAIN, post-LOW CUT, and pre-EQ. This is an unbalanced direct out, in contrast to the DIRECT OUTS on the rear panel, which are balanced direct outputs, post- GAIN, post-INSERT, and pre-EQ.
