WTSD-MIX31K

Owner’s Manual

Introduction

Model WTSD-MIX31K is a 3x1 Mic / Line / Aux / Bluetooth analog mixer that features a
balanced microphone / line input and an auxiliary 3.5mm and Bluetooth summed input
with a balanced line output. The WTSD-MIX31K utilizes commercial grade Bluetooth
technology featuring ultra low noise levels, long range connectivity, no auto connect and
quick disconnect bump feature. Selection between mic or line level for the XLR input is
done via front panel switch. The high gain mic inputs incorporate user enabled Phantom
Power for condenser microphones and a 125Hz low cut filter to eliminate unwanted low
frequency interferences. A local mute button mutes output to the bus and a system
priority button can mute building wide BGM systems to isolate the room. An adjustable
VOX feature allows for AUX input background audio to be muted when announcing is
present. The AUX input is a stereo 3.5mm jack and is electronically summed to achieve
the best audio performance. Separate level controls for each input provide control for the
audio mix needed.

A basic WTSD system consists of four elements; a WTSD mixer, Cat5/6 cable, inline 24V
DC power supply and an end point break out board / hub. All four are included with the
purchase of a WTSD mixer except for the Cat5/6 cable. A 2-gang box is all that is needed
to complete an installation. There are two versions of the WTSD end points offered. The
WTSD-PWBOB comes with each unit and features a balanced audio output with signal,
mute, system priority and power LEDs and 12V DC logic output for remote system muting
or power sequencing. The WTSD-PWHUB is sold separately and features level control
at the system head end, input limiting, isolated relay outputs to trigger system priority
muting or system power activation, and an emergency mute port. The WTSD features an
energy saving auto sleep function that can shut off the audio system when not in use
after approximately 1 hour. As soon as the WTSD mixer senses an audio signal, the WTSD
sends a command down the bus to wake the system up.

The WTSD-MIX31K analog audio BUS can easily be converted to an Audinate Dante
digital signal by interfacing with the optional AtlasIED TSD-DAC2i converter. The WTSDs
are uniquely designed to fit into most 2-gang electrical boxes and utilize industry standard
Cat5/6 cable for power, control, and audio. The WTSDs deliver high quality audio hundreds
of feet by the use of a low noise / high gain preamp design and balanced audio bus. The
proprietary low voltage bus is designed so that up to 3 WTSD mixers can be daisy chained
on the same bus cable run while allowing for independent mixer operation. Each WTSD
incorporates separate level controls for each input, a local mute, system priority override
and an auto sleep function.

The optional WTSD-COVER stainless steel weather resistant locking security cover with
gaskets is available for tamper proof indoor or outdoor applications. The PCBs are weather
treated to reduce corrosion in damp environments. With the PCB treatment and the
WTSD-COVER accessory, the installation will have protection against the environment and
tamper protection for years of continuous operation.

WTSD-PWBOB Features

The power break out box (PWBOB) is a DC power injector / trigger control / audio interface
module. Each WTSD kit comes with a WTSD-PWBOB. This module can be placed in an
equipment rack and connected to a WTSD via Cat5/6 cable. The PWBOB serves as the DC
power injector to power WTSDs. The PWBOB is also the audio interface between a power
amplifier, DSP or mixer. The indicators on the PWBOB are a useful visual guide to see the
status of a WTSD that may be located several hundred feet away from the PWBOB in the
equipment rack.

WTSD-MIX31K

Owner’s Manual

Using Commercial Grade Bluetooth

The WTSD-MIX31K utilizes a commercial grade Bluetooth technology featuring
ultra-low noise digital interference, high gain output, non-auto connectivity and a local
disconnect bump feature. These features are not found in a consumer Bluetooth device. In
commercial applications speakers that are commonly used are designed to deliver a high
sound levels (SPL). These speakers are designed to be very efficient and are sensitive to
unwanted noise from the amplifier or audio source. Bluetooth technology was intended
for consumer applications and can produce unwanted digital noise at high volume levels.
The WTSD-MIX31K was designed to reduce or eliminate the digital noise issue. Another
common issue using consumer grade Bluetooth is the auto connect feature commonly
used. Auto connect is ok when getting in and out of a vehicle, but in a commercial
application it is not good to have someone walk into a room such as a gym and auto
connect giving them unauthorized control over the audio system. Another common issue
with consumer Bluetooth technology is when someone is unknowingly connected to
the audio system and no one else can take control over the audio system because it is
connected / locked to a person in the room. The WTSD-MIX31K does not utilize
auto-connect technology and has the ability to bump a paired device from its connection
by pressing the Bluetooth music disconnect switch. These features combined make the
WTSD-MIX31K ideal for commercial applications.

1. First Time Pairing

• Turn the music level control all the way down (fully counter-clockwise).

• Press the Bluetooth music connect / disconnect switch 1 time. The Bluetooth LED will
begin to blink blue.

• Go to the Bluetooth setting on the audio device being paired.

• Find “Atlas MIX31” and select pair.

• Once paired the Bluetooth LED will turn to steady state illumination, indicating the
device and the WTSD-MIX31K are now connected.

• Before playing music, adjust the audio device level to 3/4 of the max source level.
Slowly turn the music level control to the desired listening level.

• If the device fails to connect in 30 seconds the Bluetooth LED will turn Off and restart
the pairing process.

2. Disconnecting the WTSD-MIX31K from the Paired Audio Source

• Press the Bluetooth music disconnect switch on the WTSD-MIX31K.

• Turn Off the Bluetooth feature on the paired audio device.

• When disconnected the Bluetooth LED will not be illuminated.

3. Reconnecting an Audio Source

• Turn the music level control all the way down (fully counter-clockwise).

• Press the Bluetooth music connect switch 1 time.

• The Bluetooth LED will blink. Select “Atlas MIX31” in the Bluetooth device settings.

• The Bluetooth LED will illuminate a steady state indicating the device and the
WTSD-MIX31K are connected.

• Before playing music, adjust the audio device level to 3/4 of the max source level.
Slowly turn the music level control to the desired listening level.

4. Out of Range Auto Connect

The WTSD-MIX31K has great range when compared to other Bluetooth devices due to the
antenna placement within the device. Achievable range for Bluetooth connection is 100ft
(33m) line of site. If the paired device goes out of the Bluetooth connection range from
the WTSD-MIX31K the following will happen:

• Intermittent music indicates the user needs to move closer to the WTSD-MIX31K.

• If the user walks completely out of range, the WTSD-MIX31K will remain paired to the
last device for 1 minute looking to reconnect. After 30 seconds of searching, the
Bluetooth indicator will blink indicating it is about to be disconnected from the audio
source.

• After 1 minute, the Bluetooth LED will stop illuminating indicating the audio source was
disconnected. The Bluetooth connect switch will need to be pressed to re-connect.

Things to Consider Before Installation

1. Select the correct mounting method. It is critical to fit the WTSD and the wires in
the box without causing damage to the WTSD. Refer to the section “Choosing a WTSD
Wall Mounting Method” for details on selecting the correct mounting method for the
application.

2. Check for local electrical codes for low voltage installation requirements.

3. Do not use shielded Cat5/6 cable. The RJ45 connectors on the WTSD do not have a
ground connection for the shield, so it is not necessary. The STP Cat6 can also be less
flexible when installing in a back-box.

4. If using a WTSD outdoors, make sure the optional WTSD-COVER is used and do not
expose directly to rain or snow. At minimum, place under an eve.

Things to Be Careful of During Installation

1. If using a shallow electrical back-box do not stuff the cables if there is no room. This
can damage the WTSD.

2. When running the Cat5/6 cable use standard IT wiring practices. If not, noise
interference can happen.

3. Avoid AC mains power. Never run the WTSD BUS cable parallel next to AC 120V – 240V
electrical runs and stay clear of AC outlets, or unwanted noise pick up can occur.

4. Using low grade / cost RJ45 connectors can cause an intermittent connection and
popping in the audio system may occur.

Owner’s Manual

Choosing a WTSD Wall Mounting Method

When selecting the correct installation method of a WTSD it is important to know the
state / city electrical codes. The WTSD should not be required to be mounted a in a UL
certified electrical box. This is because the WTSD family meet lows voltage electrical
codes. AtlasIED suggests following IT wiring practices. Check for local electrical codes
and requirements before starting installation. Note: It is not advisable to bundle IT-Data
infrastructure wiring runs with the WTSD-BUS long runs.

All WTSDs are designed to mount using standard 2-gang (NEMA) size hole spacing and
fasteners. Fasteners are included with the WTSDs along with a WTSD-PWBOB and a
24VDC-PSU. If only one WTSD-MIX31K or WTSD-MIX41K is used in a system, then only
one Cat5 or 6-RJ45 to RJ45 (T568 non-crossover cable), will be needed to connect the
WTSD to the WTSD-PWBOB at the head-end. If other WTSDs are needed in the same
system, then a loop thru or 2 x Cat5 or 6 (one IN and one OUT) will be the max amount of
wiring inside of a back-box.

The overall depth of the WTSDs are approximately 2.5". The RJ45 connectors plug in
vertically on the rear inside of the 2.5" depth (see diagram below). It is always a good
practice to include a service loop length of cable to allow removing the wall plate without
pulling cable and possibly damaging the WTSD. The diagram shows that 3" depth is the
minimum space required to allow for the cable to be looped.

WTSD mounting options are:

1. Electrical 2-gang box

2. Wall mount 2-gang retro fit ring

3. Direct surface mount (this requires a 3.25" W x 2.70" H hole)

Owner’s Manual

Electrical 2-Gang Box Mounting

When planning to install the WTSD-MIX31K back-box types and depth clearances need to
be considered. This document in no way includes all options available that will work for the
WTSDs. It is simply a guide to help save time when determining and planning materials
for a project.

1. 2-Gang Low Voltage Retro-Fit Back-Box

Where a retro-fit full back-box is required, most deep (3" min or 34 in3) low voltage retro-fit
2-gang back-boxes will work. Figure 1 is a Carlon 2-gang low voltage retro-fit 3-5/8" deep
box. Figure 2 is a Legrand Pass & Seymour 2-gang low voltage retro-fit 32 in3, 3" deep
back-box.

Figure 1 Figure 2

2. 2-Gang Low Voltage New Construction Box

Where Class 2 low voltage wiring is acceptable but new construction prewiring is
required, most deep (3" or 34 in3) low voltage new-work 2-gang back-boxes will work.
Figure 3 is an Arlington FA102GC 2-gang adjustable 43.5 in3, which provides the most
space for wiring found by AtlasIED. Figure 4 is a Carlon B234ADJ, 2-gang, 3" depth
adjustable back-box. It has a little less space than the Arlington. Note: This back-box is
easier to use after breaking out the Romax clamp tabs.

3. 2-Gang Outdoor Box

Figure 5 is a BELL-5389, 36 in3 metallic 2-gang box coupled with Figure 6, a Bell-5407-0B
1-1/32" deep weatherproof extension ring that fits on the front and comes with a gasket.
Use these when outdoor all-weather protection is required. In this application use a
WTSD-COVER over the WTSD to seal the assembly.

Figure 5 Figure 6

4. 2-Gang Low Voltage New Construction Rings

Where Class 2 low voltage wiring is acceptable but new construction prewiring is
required, most low voltage new construction rings will work. Figure 7 is a Thomas & Betts
CARSC200ADJ 2-gang box. Figure 8 is a Thomas & Betts CARSC200A box with Smurf
Tube mounts. Smurf Tube couplers can be problematic with the WTSDs. If the couplers
are used they need to be kept almost flush to the inside of the ring in order to clear
WTSDs.

Installing the 24VDC Power Supply

Powering the WTSD BUS requires use of the included external power supply. A UL
Certified external 24VDC 1A power supply is supplied to power the WTSD-MIX31K. It is
suggested to place the WTSD within 10ft of a 120V AC outlet. If this is not possible, the
power supply wire for the 24VDC output can be extended up to 50ft. Note: This does not
void the warranty as it is the low voltage wire that is being extended. Pay attention to the
DCV polarity when reconnecting the removable Phoenix connector. Only use the included
approved power supply or failure may occur. Must be installed by a qualified technician.
Local electrical codes will apply.

Installing the WTSD Indoors

It is recommended before installing the WTSD to review the local codes for placement
of the device. Installing a WTSD does not require using the WTSD-COVER but it is
recommended to use the WTSD-COVER for security reasons. Refer to the WTSD-COVER
section for more details. For most indoor applications, a low voltage electrical ring is all
that is required to mount the WTSD. Using an electrical ring with a WTSD allows for an
easy spacious installation.

Installing the WTSD Outdoors

If using a WTSD outdoors, it is recommended to use the optional stainless-steel locking
WTSD-COVER. The WTSD needs to be mounted in a location that is under a building
overhang or a under weather deflection shield. Note: Do not place directly in rain or snow.
Using a quality outdoor electrical box is critical to obtaining a weather sealed fit.

Using the Optional Weather Resistant WTSD-COVER

The WTSD-COVER optional stainless-steel locking cover can be used in indoor or outdoor
applications. It works with most 2-gang electrical outlet boxes. It comes with factory
mounted gaskets to seal the cover to the WTSD and electrical box. Note: If using
outdoors it is recommended to locate the WTSD and WTSD-COVER under a building
overhang. Do not place directly in rain or snow.

The WTSD-COVER is supplied with stainless-steel screws and a locking set of keys (2).
The gaskets are factory mounted; one on the ring to seal against the WTSD wall-plate, and
one on the inside of the door to seal the door when it is closed.

Installing Multiple WTSD Mixers On the Same BUS

The proprietary WTSD low voltage bus is designed so that up to 3 WTSD mixers can be
daisy chained on the same bus cable run while allowing for independent mixer operation.
Even when daisy chained each WTSD incorporates separate level controls for each input,
a local mute, system priority override and an auto sleep function. All WTSD models are
interchangeable within the WTSD BUS.

The furthest distance between the sound system front end (WTSD-PWBOB or
WTSD-PWHUB) and the furthest WTSD wall mixer is 400ft to remain within the noise
level specifications. Pay attention to the daisy chain wire looping. Refer to the diagrams
below.

Using the WTSD-PWHUB (Accessory)

In some applications, the WTSD-PWHUB can be used in place of a WTSD-PWBOB. The
advantage of using a WTSD-PWHUB over a WTSD-PWBOB is that the WTSD-PWHUB has
a variable gain control at the rack, a variable hard limiter, auto sleep and system priority
override relay contacts instead of voltage triggers. It also provides an emergency override
GPIO port to interface with fire / evacuation systems. In this example, the WTSD-PWHUB
uses the auto sleep relay to turn the main room amplifier On / Off.

Connecting a WTSD to Dante Network

The WTSD analog audio BUS can easily be converted to an Audinate Dante® digital signal
by interfacing a WTSD-PWBOB or WTSD-PWHUB with the optional AtlasIED TSD-DAC2i.
The PoE powered TSD-DAC2i transceiver has two channels of network audio and will
support two separate WTSD systems.

RJ45 Shims - There are many manufactures of RJ45 connectors and Ethernet cables
that vary in size tolerance. These slight size variations can cause intermittent connectivity
issues. This does not happen often, but if encountered, these issues can be easily
resolved by using the RJ45 shims to fill the small gap between the RJ45 male connector
and the RJ45 PCB mating receptacle. With the RJ45 inserted into the receptacle, slide a
shim between the male connector and the PCB mounted receptacle. This is shown in the
illustration below. Note: All 4 shims are not required to be used.
