Monitoring

When recording to computer software with a ProFX 

mixer, use direct hardware monitoring:

• 

Listen to the track you are recording directly off 
of your mixer, while also listening to previously-
recorded tracks on your DAW software, as they 
are fed back into the mixer.

The procedure is as follows:

• 

Arm the track you wish to record onto, on your 
DAW software, such as Tracktion.

• 

On the track you have just armed, disable input 
monitoring (see top of next page), so that 
while recording, you do not hear the return 
of that track coming from the computer. This 
will ensure you do not mix the direct track you 
are monitoring, with the duplicate of the track 
on the DAW as it is being recorded. You do not 
want to hear the direct and DAW track of the 
same source simultaneously, as the DAW ver-
sion might be slightly delayed, and the combi-
nation of the two will produce a fi ltered sound.

• 

Make sure that the DAW’s input meters show 
a healthy level, and if it needs to be increased 
or decreased, adjust the signal’s channel fader 
[31], not the gain knob [20].

• 

Press record on the DAW and record the track.

Overdubbing

To overdub additional tracks while listening to previ-

ously recorded ones, follow these steps:

• 

Press Play. The previously recorded track will 
now play out of the DAW’s main L-R mix into 
the USB input of the mixer.

• 

Set the level of the USB input level knob [40] 
to a level where you can hear the previously 
recorded track comfortably.

• 

Arm a new track in the DAW software, be sure it 
has input monitoring disabled (see top of next 
page), and record the new track on your DAW.

• 

While recording the new track, you will hear 
the previously recorded tracks coming into 
the mixer’s USB input, while you simultane-
ously hear the current track you are recording 
directly through the mixer hardware.

• 

Repeat these steps until you have built up all 
the tracks of your recording.

The mixer's built-in USB connection allows overdub 

style recording to a Mac or PC digital audio workstation 
(DAW) through the USB cable. 

Here are some steps showing how to record a fi rst 

track, and then record additional tracks while monitor-
ing ones that have already been recorded.

1.  Connect to the mixer, the sound source you 

wish to record to your audio software, for ex-
ample: 

• 

A microphone for a voice or instrument.

• 

A line-level source such as an electronic 
keyboard.

• 

An instrument connected directly to the 
instrument input 1 (with the hi-z switch 
[7] pressed in).

 2.  Make sure the USB thru switch [41] is not 

pressed in. This will ensure that during each 
recording pass, the audio software only receives 
the track-in-progress as an audio signal, and 
not the pre-existing mix from the computer as 
well.

3.  Set the gain knob [20] at the top of the channel 

you are using, to an appropriate level for the 
source being recorded, using the level set LED 
[21] as a guide. Once the gain has been set, set 
the channel fader [31] to unity (U). 

 

The signals going out to your computer are not 
affected by the main fader [48] or the head-
phones knob [42].

4.  If you are recording an acoustic source through 

a microphone, monitor it through headphones, 
not through speakers. This will prevent sound 
from the speakers from leaking into the micro-
phone. If working in this fashion, turn down 
the main fader, and instead turn up the phones 
knob for safe listening levels in the head-
phones.
