Important Safety Information
CAUTION: These servicing instructions are for use by qualified personnel only. To
reduce the risk of electric shock, do not perform any servicing other than that
contained in the User Manual unless you are qualified to do so. Refer all servicing to
qualified service personnel.
• Read these instructions.
• Keep these instructions.
• Heed all warnings.
• Follow all instructions.
• Do not use this apparatus near water. Do not expose this apparatus to
dripping or splashing and ensure that no objects filled with liquids, such as
vases, are placed on this apparatus.
• Clean only with a dry cloth.
• Do not block any of the ventilation openings. Install in accordance with the
manufacturer’s instructions.
• Do not install or use near any heat sources such as radiators, heat registers,
stoves, or other apparatus that produce heat.
• Only use attachments/accessories specified by the manufacturer.
• Refer all servicing to qualified service personnel. Servicing is required when
the apparatus has been damaged in any way, such as the power-supply cord
or plug is damaged, liquid has been spilled or objects have fallen into the
apparatus, the apparatus has been exposed to rain or moisture, does not
operate normally, or has been dropped.
• To completely disconnect mains power from this apparatus, the power supply
cord must be unplugged.
For US and CANADA only:
Do not defeat the safety purpose of the grounding-type plug. A grounding-type plug
has two blades and a third grounding prong. The wide blade or the third prong is
provided for your safety. When the provided plug does not fit into your outlet, consult
an electrician for replacement of the obsolete outlet.
The lightning flash with arrowhead symbol, within an equilateral triangle is intended
to alert the user to the presence of an uninsulated “dangerous voltage” within the
product’s enclosure that may be of sufficient magnitude to constitute a risk of electric
shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user to the
presence of important operating and maintenance (servicing) instructions in the
literature accompanying the appliance.

General Precautions
• Do not place heavy objects on the RS32, expose it to sharp objects or handle
it in any way that may cause damage, e.g., rough handling and/or excessive
vibration.
• Do not subject the equipment to dirt, dust, heat or vibration during operation
or storage. Never expose the console to rain or moisture in any form. Should
the unit become wet, turn it off and disconnect it from the power source
without further delay. The equipment should be given sufficient time to dry out
before recommencing operation.
• When cleaning the RS32, never use chemicals, abrasive substances or
solvents.
• The front panel should be cleaned using a soft brush and a dry lint-free cloth.
For persistent marks, use a soft cloth and isopropyl alcohol.
• Keep these instructions for future reference. Follow all warnings in this
manual and those printed on the unit.
• The RS32 must be connected following the guidance in this manual. Never
connect power amplifier outputs directly to the RS32. Connectors and plugs
must never be used for any other purpose than that for which they are
intended.
• The equipment must be powered from an appropriate source which can be via
either of the mains inputs. Use both inputs for redundancy purposes.
• The RS32 must not be operated inside a case or enclosed as the housing
acts as a heatsink for the components inside.
• Refer servicing to qualified technical personnel only.

Introduction
Thank you for purchasing your new Nixer RS32 audio network switch. This unit has
been designed to make it convenient and easy to switch audio signals within Dante
networks without having to change subscriptions. Operation is via it’s clear and
simple to use touchscreen interface and it is housed in a compact and robust case.
The RP32 is a 32-way digital switch with 64 digital inputs and 64 digital outputs.
Switches can be configured as either 2 inputs to 1 output changeover or 1 input to 2
outputs changeover. They can be selected individually or linked together to make
larger switches up to a maximum of 32 ways.
Any switch can be activated by the intuitive touchscreen interface.
At time of purchase, it can be specified with either a Dante or Ravenna interface.
Switches operate almost instantaneously and negate the need of having to use a
laptop and a controller program and the inherent delays these bring.
The RS32 is a compact 1U module with a size of 44mm height, 483mm width (inc.
rack ears) and 120mm depth
It features a large letterbox 6.6” diagonal (168mm) 1440 x 240 24-bit colour LCD and
capacitive touch panel for display and control

Welcome and Unpacking
Thank you for purchasing a RS32
Please take care when unpacking your product
In the box, you will find
• the RS32
• Quick Start Guide
Check that all the parts are present and in good condition
Please contact your retailer immediately should anything be incorrect
Quick Start Guide
Once you have unpacked your RS32 you can follow this quick guide to get you
started using it.
Firstly, you will need to download and install a copy of Dante Controller onto your
PC/Mac
You can download this from
https://www.audinate.com/products/software/dante-controller
Next plug your RS32 into your network with an RJ45 patch lead.
If you have plugged into a PoE enabled router/port you will see the splash screen on
the RS32 appear after a couple of seconds.
If you do not have a PoE port, then you will need to plug in a 24V DC supply with a
2.5mm barrel connector (not supplied but can be separately)
Note it is possible to plug in both a PoE supply and the external DC supply at the
same time for PSU redundancy.
The optional NIX00583 or the NIX00629 can be used to power the RS32.
Once plugged in and power applied the splash screen on the RS32 appear after a
couple of seconds.
After the RS32 has booted you will be presented with the main screen.
If you have a valid network connection the status light in the top left side of the
screen next to the P (primary) will turn green.
At this point start Dante Controller on your PC/Mac and you will see your RS32
appear in the list of devices.
You will then be able to select sources and destinations for your RS32.
For more advice on using Dante Controller please visit the Audinate Website
Once you have done this you will be able to start using your RS32 via the touch
screen interface.
Please take the time to register your RS32 here
http://www.nixerproaudio.com/Registration/registration.php
Once you have registered you will be full access to download the User Manual and
any software updates available for your RS32.

RS32 Front View
The RS32 Dante is operated and controlled via the large letterbox 6.6” diagonal (168mm)
1440 x 240 24-bit colour LCD and capacitive touch panel.
A simple and elegant menu system has been designed to be intuitive to navigate allowing
the user to access all the features of the RS32 Dante very quickly.
The high-resolution screen is easy to read presenting comprehensive metering,
routing and status information to the user.
Firmware updates of the RS32 Dante are achieved via a dedicated USB micro AB
connector on the front panel.
Rear View
On the rear of the RS32 unit there is a Primary and Secondary port for the AoIP
input.
The Control RJ45 allows the RS32 to be remotely controlled via OSC.
The Remote RJ45 is a bespoke remote-control port for additional accessories (note
it is not compatible with ethernet)
The RS32 Dante can be powered via PoE on the Primary port or alternatively via
2.5mm DC input connector and requires powering via an external (not supplied) 24V
2Amp DC adaptor.
Both PoE and the external adaptor can be used simultaneously for redundancy.
The optional NIX00583 or the NIX00629 can be used to power the RS32.
Power
Firstly, connect the RS32 Primary port to a Dante Network via a PoE enabled Switch
You will see the RS32 splash screen which will give information on the Firmware
version and FPGA version.
After a few seconds, you will see the main input screen shown on the next page
