ProDX: Rear Panel Features continued...

4. Bluetooth / Line In

This stereo input channel – 3/4 on ProDX4 and

7/8 on ProDX8 – may accept an 1/8" line-level signal

from a smart phone, MP3 player, or other signal source.

While not a “physical” connection, this is the same

channel that is used for Bluetooth, too.

This channel is selected when the BT / Line In

button [12] is engaged and the Mix button [15] is set

to Main, Aux 1, Aux 2 [ProDX8 only], or FX. Then the

level may be adjusted with the endless rotary knob.

The next two pages describe these two features

and setting input and output levels.

The Bluetooth may disconnect when affected

by electrostatic discharge (ESD) or electrical

fast transients (EFT). If this occurs, manually

reconnect the Bluetooth connection.

NEVER connect the output of an ampliﬁer

directly to a ProDX’s input jack. This could

damage the input circuitry.

A Bluetooth connection and 1/8" line-level

connection may NOT be used simultaneously.

If there is a physical connection to the

line input, it will take priority over any Bluetooth

connection. For example, if you are playing a song

from a smart phone (connected via Bluetooth)

and connect an MP3 player to the 1/8" jack, the

smart phone song will be interrupted and the MP3

player now takes precedence.

5. Main Out L/R

The 1/4" TRS output connectors provide balanced

or unbalanced line-level signals that represents the

end of the mixer chain, where your fully mixed stereo

signal enters the real world. Connect these to the left

and right inputs of your main power ampliﬁers, powered

speakers, or serial effects processor (like a graphic

equalizer or compressor/limiter).

The main out is selected when the MAIN button [14]

is engaged and the Mix button [15] is set to MAIN.

Then the level may be adjusted with the endless rotary

knob. The next two pages describe these two features

and setting input and output levels.

6. Aux Out

The ProDX4 has one aux out, while the ProDX8 has

two aux outs. These balanced 1/4" connectors are fed

a unique mix that’s created with the pre fader aux

levels for each channel. These line-level outputs

are typically (but not always) utilized for connecting

powered loudspeakers as monitors.

The aux out level is selected when the MAIN button

[14] is engaged and the Mix button [15] is set to AUX1

(or AUX2). Then the level may be adjusted with the

endless rotary knob. After ﬁve seconds of inactivity, the

selection changes back to the default “MAIN”. The next

two pages describe these features and setting input and

output levels.

7. Phones

This 1/8" connector supplies the output to stereo

headphones. This is the same mix as the main L/R,

but with its own independent output level. Headphones

are selected with the headphones icon button [17] and

the level may be adjusted with the endless rotary knob.

The phones output follows standard conventions:

Tip = Left channel

Ring = Right channel

Sleeve = Common ground

WARNING: The headphone amp is loud

and can cause permanent hearing damage.

Even intermediate levels may be painfully

loud with some headphones. BE CAREFUL! Always

turn the phones level control all the way down before

connecting headphones or doing anything new that

may affect the headphone volume. Then turn it up

slowly as you listen carefully.

8. Update

If the mixer needs a ﬁrmware update, this is the

place. Simply connect the ProDX to a Mac or Windows

PC via mini USB, run the app, and follow the on-screen

instructions.

There is absolutely no reason to do this unless

a ﬁrmware update is available (which will be

rare, if ever)...and you will know.
