Chapter 1 – Introduction
Figure 1 - The mixIT-12 console.
Thank you for purchasing a mixIT Audio Console System. The mixIT is an affordable, easy to use
Audio overIP system. With support for Ravenna, Livewire+, and AES-67 AoIP built in and Dante
support available as a plug-in option, the mixIT is easy to integrate into an existing AoIP facility
or the perfect introduction to the world of AoIP.
The mixIT is powered by the JET67 Audio Engine. The JET-67 is where all of the audio and
network connections are made. It also delivers power to the audio console. We designed the
JET67 to have sufficient inputs and outputs to connect most studio equipment for the room
based on fader size.
A 4 port Ethernet switch is built into the JET-67. It has two 1GB ports and 2 10/100 ports. The
Ethernet connections are used to configure the engine and to connect Audio over IP devices.
Logitek customers with older JetStream Mini and JetStream Plus Audio Engines can also use the
mixIT console in place of the JET-67 with a special power supply available from Logitek. The
setup of these systems is covered in a different manual.

JET-67 DANTE
This is a card that plugs into the main DSP board of the JET-67 and adds 64 x 64 channels of
Dante networking in addition to the AES-67 networking built into the JET67.
Practically speaking, it’s more audio networking than you’ll ever need for a 12 or 6 fader
console, but that means you’ll never run out of networking power, either.
If you did not order the JET-67 DANTE card when you bought your system and decide to add it
later, it can be installed in the field. The only tool you will need is a screwdriver.
About Logitek
Founded in 1979 by two Rice University students, Logitek has made audio consoles for
television and radio for more than 40 years. After helping found the campus radio station and
installing a donated audio console at KTRU, the pair decided they could design a better one
themselves and the company was born.
In the late 1990s, Logitek was the first North American company to offer a router-based digital
console. Its first virtual PC-based console was introduced in 1999. By 2009, the company had
pivoted to television, offering both physical and virtual consoles that seamlessly interface to
production workflow automation systems.
mixIT represents Logitek’s return to its radio roots, offering a simple user interface, modern
control, and the latest in standards-based networking technology at an attractive price.
Our vision for Audio over IP is simple: we believe that over time, every piece of audio
equipment will have an Ethernet jack on it, and it should be as easy to connect something to
the audio network as it is to plug an XLR into an analog or digital board.
Continuous Innovation Since 1979

Chapter 2 – System Configuration
Figure 4 - Front view, JET67 Audio Engine
With its silent, fanless operation, the JET-67 Audio Engine is designed to be installed in the
studio with the audio console.
System Requirements
The following is necessary to configure your system:
• A computer running Windows 10
• An Ethernet adapter to connect your computer to the JET67
• JetStream Server, available at https://logitek.link/XXXXXXX
• A web browser, such as Chrome, Internet Explorer, or Microsoft Edge. Firefox is not
supported.
Connecting the Console to the JET-67 Audio Engine
Using the supplied standard CAT-5 cable, plug one end into the RJ-45 port on the back of the
JET-67 and the other end into the RJ-45 port on the back of the console.
While we use a standard Ethernet cable for this connection, this is NOT an
Ethernet connection, so don’t plug it into an Ethernet switch! The console and
JET-67 communicate via a RS-485 serial connection. We are also sending
power on one pair of wires and AES-3 digital audio on another pair of wires to
drive the cue speaker.
We recommend CAT-5 for this connection to adequately provide power to the console. CAT-6
and/or thin ribbon network cable generally use thinner wire which won’t work for this purpose.
Good old-fashioned CAT-5 or CAT-5e will always work, even at a distance of 25 feet.

Audio Connections Overview
The JET67 uses quick-connect Phoenix-style terminal connectors. Insert tinned wire into the slot
and tighten the screw to secure the wire. Each terminal block has a positive terminal, negative
terminal, and common ground.
Figure 5 - rear view, JET67 for mixIT12
The JET67 works best with balanced audio. If you have an unbalanced input, we recommend
jumpering negative to ground.
Unlike a traditional audio console, the mixIT controls an audio router. Therefore, you’ll notice
there isn’t an output that’s labeled “program” or “monitor.” You decide where you want to
wire your inputs and outputs and then configure everything in the software.
Instead of having an A/B switch over the fader, you’ll choose in the software what sources are
allowed on each fader. You can have as many or as few choices as you’d like.
In the software, you will choose how many channels and input or output has (stereo or mono).
You can split a stereo pair into two mono channels on either an analog or digital input or
output.
Note that if you route a stereo mix to a mono output, the JET67 will NOT sum the two channels;
you will hear left channel only. (However, if you’re wiring up an AM radio station, we do offer a
mono program mix output so we can sum program for you.) If you route a mono input (such as
a microphone) into a fader, the JET67 will copy the left channel to the right so the input will
feed both left and right.

Connecting Your Computer To The JET67
Overview
We use a program called JetStream Server to make an IP connection to the DSP card inside the
JET67 to configure the engine.
JetStream Server, in turn, serves web pages to your web browser to enter information and
upload to the engine.
Your configuration is stored in memory on the JET67. After you have configured the JET67 you
can disconnect your PC and the audio engine will continue to control the computer. It is not
necessary for JetStream Server to be connected to operate the console.
The configuration will remain in memory on the JET67 even if power is disconnected.
You can save the configuration in a JET67 to an .XLS file and keep it backed up and you can
restore that .XLS file to the JET67 using JetStream Server.
Install JetStream Server

Connect Your PC to the JET67
1. Connect the mixIT directly to the JET67 jack marked “Console” with the supplied CAT-5
cable.
2. Connect the JET67 to power if not already plugged in.
3. Plug one of the Ethernet ports on the back of the JET67 to your local network OR plug an
Ethernet cable from your PC directly into one of the Ethernet ports on the back of the
JET67. The JET67 is set up by default to receive an IP address automatically via DHCP. If
no DHCP server is present, your PC and the JET67 will automatically select IP addresses
within the same subnet via AutoIP.
4. On the console touchscreen, tap the word “mixIT” next to the headphone selector and
make note of the IP address. This is the IP address assigned to the JET67.

number. (if mono, there will only be the Lf box to fill.) Valid numbers on a mixIT-12 are
1-12. Valid numbers on a mixIT-6 are 1-6.
5. The Mode setting determines how the fader will handle the audio when the source is
routed to the fader. The choices are:
Default: if this source is two channels, it will be stereo. If this source is one channel, it
will be mono.
Mono: if selected, a two channel source will be summed when it is routed to the fader.
Phase: phase reverse a two channel source

Logitek mixIT Audio Console System/JET67 Manual

LL: send the left channel only to both left and right
RR: send the right channel only to both left and right
Lx: left channel on left, silence on right
xR: silence on left, right channel on right
5.1: this function is not supported by the JET67
6. If you are using a GPI Input to turn the fader on or off, enter the GPI input number in
the start or stop box. The Cough box will mute the input when that GPI input turns on.
Valid numbers are 1-4.
7. For GPI Outputs: Audio Start pulses a relay when the channel turns on. Audio Stop
pulses a relay when the channel turns off. Audio Tally latches a relay on when the
channel turns on and turns the relay off when the fader turns off. Valid numbers are 1-8.
8. UDP Control: This sends ASCII text via UDP to the specified IP address using the
specified port, usually for automation control. The Start String is the text sent when the
channel turns on and the Stop String is the text sent when the channel turns off.
9.
10. To adjust the gain of the input, enter the value in DB in the IO Gain box. Negative
numbers reduce gain, positive numbers increase it. The valid range is xxx
11. Mix Minus Bus: type in the number of the mix minus bus to have this input removed
from the mix. (Example: if mix minus 1 is derived from program, then mix minus 1 will
be program minus every input tagged with a 1.) More information about mix minus is
found in DSP Settings, Mix Minus.
12. To send the audio from this input to the audio network so other AES-67 devices can use
it, check Yes for Send to Network. Set Network Latency to Low. The JET67 will stream
this source to the network and announce it to other devices using the surface label that
you entered.
13. Click Upload to JetStream to save your changes.
14. To delete this source, click Delete this local input.
15. To cancel and return to the Local IO page, click Cancel edit changes.
Creating or Editing a Digital Input
Digital inputs are handled exactly the same as analog inputs in the editor. The only difference is
in the channel assignment.
AES audio carries two channels on one wire. Therefore, to assign a stereo input on AES input
#1, assign left to channel 1 and right to channel 2. To assign a stereo input to AES input #2,
assign left to channel 3 and right to channel 4.
You can also split the mono channels into separate inputs. (For example, a satellite receiver
might have separate programming on left and right channels or a AES mic preamp might have
microphone 1 on left and microphone 2 on right.) In this case you would set number of
channels to 1 and select 1, 2, 3, or 4 as desired.
For all other settings, follow the analog input instructions.

Creating or Editing a Local Output
To create an output, click Add Output in either the Analog or Digital column.
To edit an output, click on the box for the output that you wish to edit.
You will see the output editor.
Fill in the following information:
1. Surface Label – two fields of 8 characters to identify the source internally on the
JetStream State page
2. Unique Name – give the source a unique name
3. Number of channels – select 1 for mono, 2 for stereo.
4. Assign the channels. For mono, set the Lf channel to the desired output number. For
stereo, set the LF and Rt channels to the desired outputs for left and right. If this is
analog, the channel number will correspond with the output number. If this is digital, 1
and 2 are the left and right channels of AES output 1; 3 and 4 are the left and right
channels of AES output 2.
5. Default Source – choose what audio should be fed to the output. This pick list has each
input along with the console mixes. Available console mixes:
Program Out – the main program mix
Aux 1 Out – the aux 1 mix bus
Aux 2 Out – the aux 2 mix bus
Aux 3 Out – the aux 3 mix bus
Studio Out – the studio monitor output. This corresponds to the Studio/Guest volume
knob on the console. Usually used for talk studio monitor speakers or for guest
headphones.
Phones Out – the headphone monitor output. This corresponds to the Headphone
volume knob on the console. Usually used to feed the headphone amp of the console
operator.
Phones PF – pre-fader output of the headphone monitor. Often used to feed guest
headphone amps with individual volume controls. The audio will follow what the
operator selects in the headphone monitor input, but the volume knob will be ignored.
This way the board operator who is listening to Phones Out can turn the volume up and
down without disturbing the guest.
Monitor Out – the control room monitor output. This corresponds to the Monitor
volume knob on the console.
MM 1 – MM 24 – Mix Minus outputs 1-24. See the Mix Minus section under DSP
Settings to learn how to configure mix minuses.
Mixer A Out – This is a three channel submixer that sums the source routed to MixA1,
MixA2, and MixA3 on the Surface Settings page. Commonly used to sum together
microphones for telephone feeds, it’s a lot easier to tick 3 boxes on a web page than
bury a Shure mic mixer under the console like we all used to do to feed the phone!
Mono PGM – the program bus, summed to mono
Mono Ax1 – the Aux 1 bus, summed to mono
Router 1 Out – the output to Router 1, the left widget on the mixIT fader display.
Router 2 Out – the output to Router 2, the middle router widget on the mixIT fader
