Mackie HMX-56 - page 9

Owner’s Manual

Rear Panel

The rear panel is where you make all your analog audio

connections to the HMX-56.

8. IEC Power Receptacle

This is a standard 3-prong IEC power connector.

Connect the detachable linecord (included in the box

with your HMX-56) to the power receptacle, and plug

the other end of the linecord into an AC outlet properly

conﬁgured for your particular model.

9. Power Switch

This one is self-explanatory. When the power switch is

turned ON (up), power is supplied to the HMX-56 and

the POWER [6] indicator lights up.

10. LEFT and RIGHT MAIN INPUT

These 1/4" TRS jacks accept a balanced or

unbalanced line-level input signal. Connect the main

mix output from the mixer to these inputs.

The

1/4"

TRS inputs are wired as follows:

Sleeve = Shield or ground

Tip = Positive (+ or hot)

Ring = Negative (– or cold)

If you are connecting a mono input signal to these

inputs, use a Y-Cord splitter to connect the signal to both

inputs. See “Mults and Y’s” in Appendix B for more info.

11. EFFECTS SEND

This 1/4" TRS output connector provides a balanced

or unbalanced line-level signal for connecting to the

input of an effects device.

12. L and R EFFECTS RETURN

These 1/4" TRS input connectors accept balanced or

unbalanced line-level stereo signals from an external

effects processor (or other device).

If you are connecting a mono effects return signal to

these inputs, use a Y-Cord splitter to connect the signal

to both inputs (otherwise you will only hear the effects

in one side of the headphones). See “Mults and Y’s” in

Appendix B for more info.

13. SOURCE INPUT A-D

These 1/4" TRS jacks accept a balanced or unbalanced

line-level input signal. This is the signal that you add

into the headphone mix when you adjust the SOURCE

A-D Level Controls [1] on each channel strip. You might

connect a submix output from the mixer to these inputs,

or a direct output from an individual channel (so the

talent can really crank themselves up in the headphone

mix if they want to).

These mono inputs are routed equally to the left and

right phones output.

The

1/4"

TRS inputs are wired as follows:

Sleeve = Shield or ground

Tip = Positive (+ or hot)

Ring = Negative (– or cold)

14. PHONES Out 1-6

Plug your headphones into these jacks. Each PHONES

output carries its own individual mix as determined by

the corresponding channel strip controls.

You can also connect an in-ear monitor (IEM) system to

the PHONES jack to provide an individual monitor mix.

WARNING: The headphone amps

are designed to drive any standard

headphones to a very loud level.

We’re not kidding! They can cause

permanent hearing damage. Even

intermediate levels may be painfully loud with some

headphones.

BE CAREFUL! Always start with the PHONES level

turned all the way down before connecting headphones

to the PHONES jack. Keep it down until you’ve put on

the headphones. Then turn it up slowly. Why? Always

remember: “Engineers who fry their ears, ﬁnd

themselves with short careers.”
