FLOW 8 Controls
(1)  MIC 1/MIC 2 inputs accept 
audio signals over cables using 
balanced XLR connectors. Both 
XLR jacks feature individually-
selectable phantom power for 
condenser mics. Phantom power 
can be activated in the control 
app or via the MAIN button and 
SELECT/ADJUST push encoder (see 
"Getting Started").
(2)  MIC 3/MIC 4 combo jacks accept 
audio signals from line-level 
sources or dynamic microphones 
over cables with balanced XLR, 
balanced ¼" TRS or unbalanced 
¼" TS connectors. To run 
condenser microphones with 
these inputs, you will need an 
external preamp or phantom 
power supply that provides  
+48 V of power, such as the 
Behringer PS400.
NOTE: These inputs do NOT oer 
phantom power!
(3)  FOOTSW jack connects to an 
external single or dual 
control footswitch using a ¼" 
TRS connector. 
(4)  PHONES jack connects to 
headphones using a 
 ¼" TRS stereo plug.
(5)  MAIN L/MAIN R connections send 
out the nal stereo mix over cables 
using balanced XLR connectors.
(6)  STEREO/MONO inputs can accept 
either stereo line-level signals 
(5/6 and 7/8 stereo pairs), or a 
mono signal (5L and 7L for mono 
line-level sources, 6R and 8R for 
mono Hi-Z signals from guitars 
and basses.)
(7)  MONITOR SEND  
(MON 1/MON 2) jacks provide two

place your smartphone directly 
onto the mixer for easy viewing 
of levels and settings on the 
smartphone control app.

selected in the controlapp or by 
pressing the menu layer’s related 
hardware button (see [16], [21] 
and [22]).
(10)  OFFSET/CLIP LEDs indicate when 
the input gain is clipping the 
channel headroom or when the 
hardware faders are in a dierent

shown in the control app (the LEDs 
will switch o when the hardware 
faders are returned to the level 
shown in the control app).

MON 2 menu layer is selected. 
Pressing the MENU button again 
will exit from Menu Mode.

between the two FX engines for 
patch selection and parameter 
adjustment. When the FX 1 or 
FX 2 menu buttons are selected, 
the channel faders are then used 
to set Send levels to the 
FX engines.
(17)  MENU SCREEN displays the names 
of the currently-active eects for 
the two FX engines, and allows 
access to the FX preset list when 
the FX 1 or FX 2 button is pressed. 
Press the MENU button to open 
and close Menu Mode. Rotate the 
SELECT/ADJUST push encoder to 
navigate sub-menus and  
then press to select specic 
menu items.

time-based eects.
(21)  MON 1/MON 2 buttons select 
either of the monitor mixes 
for direct monitoring and level 
setting in place of the main mix. 
To return to the main mix, 
press the MAIN button. 
Press MON 1 and MON 2 
simultaneously to active the  
EZ GAIN function 
(see "Getting Started").
(22)  MAIN button selects the main 
mix for the nal output. Press the 
MAIN button to return to the main 
mix after selecting and checking 
monitor mixes with the MON 1 and 
MON 2 buttons. Press and hold 
the MAIN button for manual gain 
setting and to activate phantom 
power (see "Getting Started").
(23)  VU METER shows levels for the 
main mix, monitor mixes or FX 
send signals. In SOLO mode, 
this meter allows more detailed 
gain setting on individual input 
channels. The red LEDs "1" and "2" 
at the top of the meter will light 
up when +48 V phantom power is 
activated for Channels 1 and 
2 respectively.
(24)  MAIN knob controls the master 
volume for the currently selected 
buss – FX 1, FX 2, MON 1, MON 2 or 
MAIN. The nal volume setting is 
indicated by the LED ring around 
the knob. When adjusting the 
master volume setting of the 
currently-selected bus from the 
smartphone app, the LED ring 
will change to show the volume 
setting selected for that bus in 
the app.
(25)  USB AUDIO jack enables 
connection to a computer for 
audio streaming, rmware 
updates and MIDI control. 
This USB connection also 
allows FLOW 8 to be used as 
multi-channel audio interface for 
recording to computer.  
When used as a recording 
interface, 10 channels are 
transmitted to the computer 
(8 analog inputs, plus the main 
L/R bus mix tapped pre-fader), 
and 2 stereo playback channels, 
controllable via the BT/ USB 
channel, are streamed back to the 
FLOW 8 mixer.
(26)  DC IN jack uses a Micro-USB 
connection to provide power to 
the unit. Power should come from 
either the included external power 
supply or a USB power bank with 
a Micro-USB connection.
