ONYX 1640

Rear Panel

This is where all the connections are made to the Onyx 1640 (except the headphones and the lamp).

One of the things that revolutionized the compact mixer industry was the “convertible pod” found on the original, classic CR-1604. Using an ordinary phillips screwdriver, the mixer could be converted from desk- top mode (as it comes from the factory) to rackmount mode. Fear not. This feature is so popular that we have kept it in the Onyx 1640. Refer to Appendix D for instructions on converting the I/O pod for rack mounting.

A third option allows you to rotate the pod so that the jacks are on the same plane as all the knobs, buttons, and faders. This is a lifesaver when you have to do frequent repatching of the connectors. This, however, requires the optional rotopod bracket, not supplied with the Onyx 1640. Contact your Mackie dealer for details.

47. 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 groundPin 2 = Positive (+ or hot)Pin 3 = Negative (– or cold)

48. LINE Input (Channels 3-16)

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
49.HI-Z Instrument Input (Channels 1-2)

This is a 1/4" connector, which accepts an unbalanced instrument-level input signal from a high-impedance instrument like a guitar.

50. CHANNEL INSERT

These 1/4" TRS jacks provide a send and return point for channels 1-16. Use the CHANNEL 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 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)

“tip”

sleeve

 

this plug connects to one of the

“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 RECORDING OUTS on the rear panel, which are balanced direct outputs, post-GAIN, pre-LOW CUT.
