Overview – App Control
Dayton Audio Matrio Control Mobile App
The Dayton Audio Matrio Control app allows for complete control of all of the Matrix88 or DAX88
units on your network. The Zone Control menu allows for individual control over each zone of
your system, and the Group Control menu is an advanced feature that lets you send commands
to many or all zones at once, even zones that are on separate units. The settings menu has
controls for custom naming your inputs, zones, and even the device name. All customization is
stored on the Matrix88 or DAX88 itself, which means that end users can open the app can use
the system without any knowledge about how the system is wired.
For more detailed information about Matrio Control, see the dedicated Matrio Control section of
this guide (p.27) and also download the free app from the iOS or Android app store. The app can
be fully explored and experienced in demo mode even without a Matrix88 unit.

line level audio zones in the form of stereo RCA jacks. These outputs can be connected to
external ampliers.
2. Zone Preamp Outputs 7-8 – Like the previous Zones, Zones 7 and 8 have preamplied,
analog line level RCA connections for connecting external ampliers. These zones also have
Optical Toslink outputs for connecting external equipment with a digital Toslink connection.
3. StereoRCAInputs–Inputs 1-4 have stereo RCA jacks for connecting any analog input
source like TV’s, DVD players, Streamers, CD players, etc.
4. Stereo 3.5mm Inputs – Every input 1-7 has a stereo 3.5mm jack for connecting analog input
sources such as cell phones, tablets, laptops, wireless receivers, etc.
5. OpticalToslinkInputs–Inputs 5 and 6 feature optical Toslink inputs, which are useful for
attaching digital audio sources, such as from a TV, DVD player or wireless streamer. The
output of your audio source must be manually set to Stereo PCM if automatic settings do not
work.
6. Wi-Fi Antenna –
Allows the Matrix88 to be connected to your network wirelessly. Dayton Audio
recommends to always use a wired ethernet connection instead of Wi-Fi whenever possible.

7. AC Input – This unit comes with an IEC jack that permits the removal of the AC power cord.
This allows exibility of changing thew power cord for different countries. The IEC socket also
houses the main fuse holder. Plug the power cord supplied with the amplier into this socket
and to a wall socket or appropriate surge protector.
8. KeypadConnections–These RJ45 jacks allow you to connect optional DAX88KP Keypads,
which allow per zone control without the use of the mobile app. Note: These ports are labeled
1-8, however the dipswitches on the back of the keypad need congured so they control the
correct zone (p.19).
9. 12VDC Trigger Outputs – Useful for automation systems, each zone has a corresponding
12V trigger that will output 12V when the zone is on, and 0V when the zone is off. This can
be useful to trigger the power state of other equipment like external ampliers, video screens,
or anything else with a 12V input trigger that corresponds with that zone (p.25).
10. 12VDC Trigger Inputs – Applying 12V to the Mute Trigger will mute all zones, and will
unmute all zones if the signal is removed (0V). Applying 12V to the Power On Trigger will turn
on all zones. The Zones will remain on even when the 12V signal is removed. The power on
trigger can be even more useful when combined with the automatic standby function (p.25).
11. SerialPortforRS232ControlandDeviceUpdates–This port allows RS232 commands
to be sent to and from the DAX88, which can be useful for automation systems. This port can
also be used to upgrade the rmware on the Matrix88. See the “RS232 Control” section for
more details.
12. USB Power Outputs – Useful for powering or charging external devices such as streamers,
tablets, etc, these USB ports are for power only and will not transmit any data. The ports are
capable of 5V, 1A of output each.
13. NetworkLANConnection–This RJ45 jack allows the DAX88 to be connected to your
network via a standard ethernet patch cable.

Overview – Keypads
DAX88KP – Keypads (Oponal)
The DAX88KP Keypad is designed for ease of use with accessible controls over the
corresponding Matrix88 zone. Soft-touch backlit buttons and a backlit LED display provide
convenient control of the zone’s power status (ON/OFF), source selection, volume, treble, and
bass controls. A built-in IR target or external IR target connected to the EXT-IR terminals on the
rear of the keypad, relay commands to the Matrix88 main unit through your DAX88IR IR Remote.
A DAX88KP will control one zone at a time, which is congurable with dip switches on the back of
the keypad.
Five LEDs on the keypad face indicate the operational function of the keypad. The EXT LED
indicates that the system is receiving a trigger command from an external IR target.

Overview–IRRemote
DAX88IR – IR Remote for Keypads (Oponal)
The DAX88IR Infrared Remote Control provides complete zone control through the built-in IR
receiver on the Matrix88’s keypads. All keypad functions can be accessed using the DAX88IR.
In addition to the keypad functions, the DAX88IR has a mute button to temporarily mute audio
in the corresponding zone. Once the mute function is activated the keypad’s LED display will
ash, indicating the mute status is active. To deactivate mute, press the mute button again on the
DAX88IR Remote, or disable mute with the Matrio mobile app.

Overview–ExternalDevices
Ampliers,StreamersandotherExternalDevices
Zone Outputs
As a line level device meant for distributing audio, the Matrix88 will require external equipment
in order to produce sound. Specically, it will require external ampliers to power your speakers.
The Matrix88 cannot drive speakers directly unless the speaker has a built-in amplier. The
Matrix88 is compatible with any amplier that has an analog, unbalanced line input, or an optical
input accepting stereo PCM. The connector type used on the Matrix88 for output are stereo RCA
jacks. However, common adapters can be found at any audio retailer to adapt these outputs to
work with ⅛ inch (3.5mm) or ¼ inch cables.
Examples of common output devices for the Matrix88 are:
1) Amulti-channelamplierthatdoesnothaveappcontrol– The Zone Outputs of the
Matrix88 can be used as a source for each of the zones on any multichannel amplier,
(p.16) which can be used to bring smart features to an existing amplier, effectively
upgrading your multichannel amplier to function similarly to a Dayton Audio DAX88.
2) A70VAmplier– Many commercial installations already use ampliers like this to
power many speakers in a row that all play at once and do not require individual control.
The Matrix88 can be used as the audio input to an amplier like this, which can bring
app control to an existing installation. This might be especially useful if you intend on
expanding a business with existing audio that already works, but you want to add more
zones with individual control.
3) Powered Speakers – With speakers that already have amplication built in, such as
studio monitors, party speakers, PA Speakers, etc, the Matrix88 can be easily connected
to these speakers analog inputs and used in a larger whole home or business system.
4)
Powered Subwoofers – The Matrix88 can be easily connected to most powered
subwoofers, as long as they have analog inputs. In the example above of upgrading an
existing 70V Amplier system, you could use one zone to connect to the 70V amplier,
and another to a powered subwoofer or subwoofer amp to add some oomph to the
environment the 70V system is in.
5) AmplierFlexibility– In one room, you might only require 50W per channel to power
your ceiling speakers. In another room, you might have a 500W amplier powering some
big tower speakers. Unlike multichannel amplifers, the Matrix88 gives you the exibility to
put the power where you need it, while maintaining control over each zone with the Matrio
Control app.

12
Overview–ExternalDevices
Input Devices
The Matrix88 has RCA inputs, 3.5mm inputs, and even digital optical inputs to make it a breeze
to attach any input device you might have to your Matrix88, such as an external streamer, TV,
radio, CD player, turntable or anything else you can think of. The included USB power jacks
provide 5V, 1A of power which is enough to power many external streaming devices, such as
Airplay receivers, Chromecasts, Alexa Devices and more.
Triggers
The included input and output triggers can be useful for additional automation of your system.
For example, your external amplier, might have input triggers that can turn the device on when
it sees a 12V signal. The Matrix88 can output a 12V signal from any zone when it is turned on,
which could turn on your external amplier. Or, perhaps you have a projector screen that you
want to come down from the ceiling when zone 4 turns on. If the motor of the screen has a 12V
input, this can be easily done. For more information, see the section on Triggers (p.25).

Installation – Before you Start
Matrix88 Installation
With included feet and rack mount options, the Matrix88 is easy to install in a variety of
scenarios. Install the Matrix88 in a well-ventilated location. Make sure that your installation of
the Matrix88 does not impede airow to your connected ampliers or networking equipment. The
Matrix88 should not be placed directly on top of an amplier or other heat generating equipment,
especially if it blocks any vents. Do not expose the unit to excessive dust, do not allow dust to
build up on the unit.
Overview (Read Fully Before Installaon)
1. The Matrix88 can be mounted in a standard 19” A/V equipment rack using the included rack
mount kit.
2. When possible, test that all of your speakers, ampliers and input devices are working
properly before attaching them to your Matrix88.
3. Plan on installing your Matrix88 in a location where you will have wired network access. This
means you can install the Matrix88 near a network switch, or plan to run a Cat6 network wire
from your router to the network port of your Matrix88. Although it is possible to congure
the Matrix88 to the network using Wi-Fi, it is not recommended for stability. More details
about network conguration are found in the sections below. If you connect your Matrix88
wirelessly, it is imperative to have a strong signal.
a. Ensure that you have a robust and stable wireless network before installing your
Matrix88, even if you are connecting your Matrix88 to your network via ethernet, as
interfacing with the device will still happen wirelessly via a phone, tablet, etc. Control
of the Matrix88 through the Matrio Control app will not work properly without a working
and reliable wireless network. If connecting your Matrix88 wirelessly, your network
must support the 2.4Ghz spectrum.
b. If you are using a router that was given to you by your internet service provider,
consider upgrading to a higher quality router, as ISP provided routers are often not of
high quality, especially units that are both modem and router combined.
c. Plan to have a secure wireless network with access to the same VLAN that the
Matrix88 is connected to, that only trusted phones, tablets, etc will have access to.
With the Matrio Control app, any user on the same network as the Matrix88 will be
able to make changes to the system via Matrio Control.
4. Use high quality cable for connection of the keypads to the Matrix88. We recommend Cat5e
cabling to connect keypads, but you can also use Cat6 or better. Because audio is not
transmitted through this cable, the performance of Cat5e at a minimum is adequate. Higher
quality ethernet cable will NOT improve audio performance. Buying cabling pre-terminated
with RJ45 connectors (ethernet patch cables) might be desirable if you do not want to
terminate the wire yourself. Additionally, keypads must be congured using the dipswitches
on the back of each keypad. Plugging a keypad into the rst keypad port will not make it
control zone 1 automatically, you must congure the dip switches.

14
Installation – Before you Start
5. Following installation of your Matrix88 unit, ampliers, speakers, inputs, keypads and other
accessories, the power switch on the front of your Matrix88 device will need to be switched to
the ‘ON’ position before it can be used.
6. It is highly recommended to label all of your wires during the installation process, which will
make it much easier to fully setup your device in the Matrio Control app following installation.
7. The Matrix88 provides convenient 5W USB-A ports (5V, 1A) to power additional streamers,
adapters, tablets, or any other USB powered devices. These USB ports are not an audio
input, and will not interface with the Matrix88. These ports will each provide 5W even if both
are being used at once.
8. Use high quality ampliers with the Matrix88. Test all ampliers before connecting them to
your Matrix88.
9. When rst turned on, each of the Matrix88’s zones will be off, and will need turned on for use.
The default matrix routing is that input 1 is routed to zone 1, input 2 is routed to zone 2, and
so on. Keep this in mind when you rst test your Matrix88 after installation.

15
Installation–Zone/AmplierConnection
ZoneConnection(ConnectingExternalAmpliers)
The Matrix88 is a line level device, with 8 stereo zones represented with RCA jacks on the back
of the unit that will output line level analog audio signals. RCA outputs can be used to distribute
an audio signal to ampliers, powered speakers, or even a powered subwoofer. Connect one end
of a set of RCA cables to your desired zone of the Matrix88, and connect the other end to your
amplier or speaker.
ANoteonCables: Use only high-quality, single ended, shielded RCA cables for connecting external
ampliers to the Matrix88. It is not necessary to use esoteric materials or audiophile branded cables
for your system. However, there are many RCA cables (often included with devices, rather than
individually sold) that are very low quality and can introduce noise into your system. If you are unsure
where a set of RCA cables came from, it is fair to try them with your system. But if there are any
unexpected issues with sound quality, such as audible noise or distortion, we recommend trying
higher quality cables from a reputable company rst. Many cables do not have any shielding, use
poor quality materials, have poor construction, etc. If the audio quality of your system is good but you
want it to be better, we recommend upgrading your speakers or ampliers, not your cables unless
there is a distinct issue with your cables.

16
Installation–Zone/AmplierConnection
Example - Connecng to a Mulchannel Amplier
A typical use case of the Matrix88 is to connect it to an existing multichannel amplier to retrot
the device with app controllable features and wireless streaming. These ampliers often have
inputs for each zone of amplication, so each zone output of the Matrix88 can be connected to
the zone input of the multi-channel amplier, and effectively add the network controllable features
of the Matrix88 to the amplier. In this scenario, it is often helpful to connect the output triggers of
the Matrix88 to the input trigger of your amplier, as seen in the trigger section.

17
Installation–InputsConnection
InputConnection
The Matrix88 has 8 inputs with a variety of connector types (RCA, 3.5mm, Digital Optical, and
wireless streaming). These inputs are part of the device’s matrix, which means any input can be
assigned to any zone and changed at any time. For example, one day you might want a different
input per each zone for individual listening. The next day, you might want to broadcast your TV
audio to every zone so no one misses anything about the big game. With the Matrio Control app,
each input can be given a custom name that better describes it and makes it simple for the end
user to control. Use only high quality cables for connecting external inputs to the Matrix88.
• Inputs 1
-
4 are stereo, unbalanced, line level source inputs via RCA style female connectors
or a female 3.5mm jack. If both inputs are present, the audio from each will mix together.
•
Inputs 5
-
6 have options for TOSLINK (optical) input, or analog audio input through a 3.5mm jack.
• If using TOSLINK, make sure to use “PCM-Stereo” or Auto Detect setting on your
source device. Your device should be set to auto detect by default and work properly,
but if not, you can usually nd these settings in settings -> Audio -> S/PDIF or
something similar. Refer to the user manual of your source device. You will know if
your settings are correct or not, because if they are incorrect, the sound will be digital
noise rather than proper audio. Keep the volume of any zones set to this input very
low until you have veried the audio is correct and not digital noise.
• The 3.5mm jack will take priority over the TOSLINK input, meaning that if anything is plugged
into the 3.5mm jack, the TOSLINK input will be disabled. These inputs will NOT mix.
• Input 7 is a 3.5mm jack for analog, stereo audio.
• Input 8 is Wi-Fi streaming, and is represented on the back of the Matrix88 with a wireless
antenna. More information about wireless streaming can be found in the “Wi-Fi Streaming”
section of this guide (p.32).

18
Installation–InputsConnection
Sharing your Inputs to Mulple Matrix88 Units
If you have multiple Matrix88 units and want to use the same input device on all of them, you
have a couple of options.
1) The preferred option is to split your input source and route it to both devices. There are many
devices and cables available from your Dayton Audio retailer that will split an analog or TOSLINK
signal so you can connect it to multiple Matrix88 devices. You will need to name both inputs
the exact same name within the Matrio Control app for each Matrix88 unit to ensure that group
control input switching works correctly. See the diagram below, which is an example using a CD
player as an input connected to Matrix88_1 and Matrix88_2 using an aux splitter (male 3.5mm to
dual female 3.5mm).
2) All of the Matrix88’s zones are line level RCA outputs. One of these zones could be used to
route the desired audio source from your rst Matrix88 into your second Matrix88. For example, if
you are streaming music using the Wi-Fi input of your rst Matrix88, set either zone 7 or 8 of your
rst Matrix88 to input 8 (Wi-Fi), and then connect zone 7 or 8 to one of the inputs on your second
Matrix88. This will effectively share the desired input between your devices if the correct zone on
your main Matrix88 is turned on.

19
Installation – Keypads
Keypads
In addition to control via the Matrio Control app, each individual Matrix88 zone can be controlled
with keypads that can be mounted into a standard single-gang wall plate. Up to 8 keypads
(one per zone) can be installed directly to the Matrix88 via the 8 RJ45 jacks (also known as an
ethernet jack). Keypads offer convenient control for volume, source input, bass and treble. The
keypads also feature an IR sensor that can be used with the DAX88IR Remote Control to control
a keypad wirelessly.
1) Use high quality Cat5e/6 cable between the Matrix88 and DAX88KP keypads. Proper
installation techniques will guarantee that the keypads will work properly up to 600 feet from
the Matrix88. The use of RJ45 (typical ethernet) connectors on the keypads and keypad hub
means that pre-terminated cables can be easily sourced, and the equipment to terminate
Cat5e/6 cable yourself can be easily found, if necessary.
2) Use standard electrical boxes or low voltage rings to mount the keypads.
3) Theswitchesonthebackofthekeypadmustbeconguredsotheycontrolthecorrect
zone. Although the Matrix88’s keypad jacks are labeled with 1 – 8 for each of the eight zones,
the dip switches on the back of the keypads must be set so they correspond to the correct
zone like the chart below shows. Plugging the keypads into the 1 – 8 labels of the hub does
NOT determine which zone each keypad controls. Setting the dip switches gives each keypad
a distinct address. The up position is ‘ON’, whereas the down position is ‘OFF’ This chart is
also found on each keypad for ease of installation. The example on the right has the correct
settings for “Zone 3”. IMPORTANT: If you do not complete this step for each keypad, your
keypads will not control the correct zone.

Installation – Keypads
4) If you are crimping your own RJ45 jacks, the ‘B’ conguration should be used. This is the
‘standard’ conguration, and is how a typical ethernet patch cable you would buy from a
retailer is wired.
5) A standard IR target can be attached to the back of the keypad to the green port with labels
+5V, GND, and Data. This can be useful if you want to be able to point the remote a different
direction than where the keypad is.
