Introduction
The Z Series is a multi-zone speech privacy system that also supports background music and paging applications. Model Z2-B is a two-zone speech
privacy system providing 60-watts of total amplification and model Z4-B is four-zone speech privacy system delivering up to 120-watts of amplification.
The Z Series is an all-in-one solution that not only supplies high quality speech privacy, but also can deliver high quality background music and paging.
Mic / line and music inputs each have a five-band equalizer and Hi and Lo pass filters to assure maximum performance. Music inputs incorporate either
analog stereo summed inputs or Bluetooth®streaming. For paging applications, the Z Series incorporates a unique hi-Q feedback filter specifically
tailored to the vocal frequency range. Output limiters are in the audio chain to protect against system overdrive.
Advanced features of the Z Series include separate analog masking generators per zone, 14-day system commissioning ramp per zone, and PC project
design software allows system custom project files to meet installation needs.
For conference room applications where secure speech privacy is required, the Z Series features a Speech Privacy Enhancement mode that can be
engaged while a meeting is in progress. Enhanced Privacy mode applies additional acoustical energy to the surrounding environment, increasing the
privacy levels for the conference room occupants. These unique secured speech filters have been approved and implemented in many installations
around the world including military and government facilities. Activation of the Speech Privacy Enhancement feature is accomplished via hardwired
switch, an iOS®or Android®application, or using an optional wireless desktop / wall mount switch. An optional wired or wireless sign is available for a
visual aid to notify attendees when Enhanced Privacy Mode is active.

Opening the Z Series
1. Remove the two Control Panel Dress End Caps. These End Caps are held by magnets with guide pins for alignment. They need to be lifted away
from the panel. See Figure 2.
2. Remove the six Control Panel mounting screws.
3. Carefully tilt back the Control Panel to access the I/O Backbox. The Control Panel and I/O Backbox are connected via harness as seen in Figure 4.
Note: Remove the harness connectors from the Control Panel and leave the cables connected to the I/O Backbox.
Mounting the Z Series
The Z Series can be surface mounted, in-wall flush mounted, or rack mounted. Before mounting the Z Series, there are several factors to take into
consideration. Select the best area for wiring infrastructure such as speaker wire, AC mains power, paging cable and background audio source cables.
Placement of the Z Series is also critical when using the Bluetooth®audio streaming feature. The Z Series should be placed within 50ft of the paired
audio source. Powering the Z Series requires use of the included external power supply. It is suggested to place the Z Series within 6ft 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. Note: Pay attention to the DCV polarity when reconnecting the removable Phoenix connector.
Wire Routing
The I/O Backbox wall mounting can be secured by applying screws to a surface, in-wall, or to a 2-gang electrical box. Wiring into the Z Series can be
done via rear 2-gang opening of the I/O Backbox or via electrical conduit 3/4" and 1/2". Knockouts are located on the top and bottom of the I/O Backbox.
For wiring the Inputs and Outputs see “Wiring the Z Series I/O Backbox”.

In-Wall Mount
1. Cut a hole in the wall (8.27"H x 10.83" W). Make sure the hole has at least 2" of rear clearance. Note: Aligning one side over a stud is the easiest
and most secure method. See Figure 13.
2. Remove the front Control Panel from the I/O Backbox. Be careful removing the cables from the Control Panel PCB.
3. Remove the Dress Ring from the I/O Backbox to allow access to the side mounted wall mount brackets.
4. Temporarily fit the Z Series into the wall cut-out and adjust the side brackets so the front of the I/O Backbox sits flush to the finished wall.
5. On the opposite side of the stud, use an EZ Anchor or add a small backing block (wood) to screw into. Note: The center of the wall mount bracket
has an opening large enough to allow a drywall screw to hold the wood backing block in place while mounting.
6. After mounting in-wall, re-fasten the Dress Ring to the front of the I/O Backbox.
7. Wire the I/O Backbox. See “Wiring the Z Series I/O Backbox” for details.
8. After the I/O Backbox is wired, re-install the front panel (carefully plug in cable connectors, fold closed, and fasten 6 screws) and apply the two
magnetic end caps. Note: Do not force closed or damage may occur. Realign the wires if necessary for smooth panel closure.

Understanding Unique Menu Tree Features
Masking & Privacy Volume Adjust - Each Zone has its own Masking and Speech Privacy Enhancement adjustments. These are separate adjustments
but are relative to each other.
1. Masking Level Zone 1 - This adjusts the Level of Sound Masking only in Zone 1. Note: This adjustment is Pre or Before the Master Zone Level 1.
2. Privacy Level - This feature is designed to temporarily change the masking level. This feature is ideal to use in a medical
office, conference room, or any area that needs a more secure speech environment to prevent conversations from being overheard. When
engaged, the Level at Zone 1 output will increase by the Privacy level entered. In most cases 6dB is common. This Privacy fader level is “relative”
to the Zone fader level and is not active regardless of the position of the fader until the Speech Privacy Enhancement ports “G” and “Engage”
are shorted together or the Z-SIGN or App activate it. Refer to their specific manuals for details. Note: The Privacy Enhancement does not change
the Music (BT / AUX) or Paging (Mic / Line levels). We recommend following the Privacy Enhancement examples listed on the web site to
understand the masking signal flow and gain structure.
Mic & Phantom Adjust (Mic or Line Gain Select) - In this section the Balanced input can be configured to be at Mic or Line Level. If Mic mode is
selected you can also turn on the Phantom 24vDC power if required.
Mic Feedback Filter Adjust - If the Balanced input is selected to Mic mode and you are experiencing feedback while paging, the Z2 / Z4 has a
specialized filter to reduce or eliminate the feedback. Navigate to On / Off, select On, then adjust the frequency Up or Down until the feedback is gone.
This notch filter frequency adjustment range is 200Hz to 6KHz with the level being fixed at -20dB cut with a Q14 (0.1 BW)
System Commissioning Ramp (SCR) - Each Zone has it is own SCR On / Off function and they operate independently from each other. When
turned on, the SCR function last for 14 days with each day representing 1dB of change. When the SCR is turned On, the display will show number 14
representing the numbers of SCR days left. The Masking Level will be down -14dB from the set Masking Level. Note: The SCR is a count down timer
that displays the number of days left. When it gets to 0 days, the SCR will automatically turn Off. At this point the Masking level is where the Masking
fader is set to. The clock must be set for the SCR to function.
Example: If the Masking A Level is -10dB and you select 14 Days for the ramping to take place, then turn ON the SCR, the Masking A Level is -24dB.
The next day the SCR changes to 13 Days and the Masking A output level increases by 1dB making the Masking level -23dB. This will continue until
the SCR days reach 0 Days and the Masking A level reaches -10dB. The SCR will turn OFF automatically.

SHS EQ
Some speakers require unique EQ processing to maximize their performance. This does not mean the speaker will not function without the specific
EQ settings. When using an SHS speaker with a Z2 / Z4 for background audio or paging applications, use the custom EQ setting. AtlasIED has made a
simple SHS EQ On or Off setting for Paging or Music. This setting is located in the navigation tree. When On, this SHS EQ will be applied to all zones.
The Music & Paging EQ are still available for room tuning.
Note: This feature only works with firmware v1.64 or higher and software v1.10 or higher.

Z Series Optional Accessories
Note: All series accessories can be used together.
A. ASP-MG2240S - The Enhanced Privacy In Use Wired Sign is used to inform the public that a Sound Masking system is in use for their security
while having a private conversation. This wired privacy sign is designed to be integrated with the Z Series. The ASP-MG2240S is a 10V DC voltage
powered Acrylic LED Diffusion type sign featuring a multi-functional mount with a polished aluminum finish. The ASP-MG2240S can be mounted to
a wall or to a single gang electrical box. The mounting hardware is included to support most installation requirements.
B. WPD-SWCC - A décor style wall plate featuring a push button switch that activates/deactivates a hard latch contact closure. This product is
designed to be used with compatible AtlasIED products that are designed to be remotely activated. The unit is constructed of durable ABS material
and includes a red LED system status indicator as well as a removable label guard for easy and clean designation of switch function. The unit has a
four-conductor interface connection designed to work with the included Phoenix style connector. This unit can function in remote activation
scenarios up to 200 feet from the controlled unit using 22-gauge wire.
C. Z-SIGN - The AtlasIED Z-SIGN Enhanced Privacy Sign is used to inform the public that a Sound Masking system is in use for their security while
having a private conversation. This wireless privacy sign is designed to be integrated with the AtlasIED Z Series High Definition Acoustical
Systems. The Z Series sign works in conjunction with models Z2-B & Z4-B base units. The Z-SIGN is a wireless transceiver that can be used to
activate the System’s Enhanced Speech Privacy Mode and illuminate indicating the room is secure. The Z-SIGN utilizes 915MHz wireless
technology for communication to the Z2 & Z4 base units. This technology assures communication from the sign to the base unit through walls and
up to 100ft apart. The Z-SIGN also utilizes BLE®technology for the Z-SIGN to communicate to a phone or tablet via iOS®or Android®App. This App
allows for the customer to engage Speech Privacy Enhancement, plus it allows for the installer to adjust the zone levels remotely during system
setup. If using an App, the Z Series features an Enhanced Speech Privacy switch to allow for the sign to set on a desk. The Z-SIGN utilizes high
quality rechargeable batteries to assure maximum usage between charges. The Z-SIGN can also be powered utilizing the included power supply.
Refer to the Z-SIGN data sheet for more information.

D. Z Series App for iOS®or Android®- The Z Series App can be used to engage the Z2 or Z4 into the Enhanced Speech Privacy Mode. It can also be
used to remotely adjust music, paging and masking levels per zone. Each input can be tuned to meet each zone’s acoustical requirements.
Note: The level and tuning section of the Z Series App is password protected.
• The App uses the smartphone Bluetooth®BLE®technology to connect to the Z2 / Z4 Base unit. The distance of the Bluetooth®transmission is
around 100 ft line of site. To avoid dropouts, it is recommended to be in the same room as the Z2 / Z4 base units and stay within 50ft.
• If longer distance is required a Z-SIGN can be used to act as a relay-bridge between the phone App and the Z2 / Z4 base units. The phone
connects to the Z-SIGN via Bluetooth®BLE®and the Z-SIGN transmits the commands to and from the Z2 / Z4 Base units via UHF frequency.
The UHF allows for much greater transmission distances compared to Bluetooth®. It is common to get command transmission distances over
100 ft but will vary depending on the building construction and number of walls it has to go through.

Turning on the Z Series
Press and hold (3 sec) Enter on the Navigation control button and the unit will boot up. Don’t be alarmed if you are hearing masking present at the
speakers. The Masking Level is set low to allow walking the area to see if all the speakers are functioning. Levels can be adjusted via the Navigation
controls. From here select a different preset and change functions. Note: Settings are automatically saved when powering off or if there is a Power
Failure.
Streaming Audio and Bluetooth®Paring
Streaming music from an audio device using Bluetooth®is a convenient way to run background audio without having wires in the way. However, there
are limitations to Bluetooth®technology. Bluetooth®operates best when the audio device and the Z Series base unit are close to each other. Line of
sight is always best. Bluetooth®can go through a wall as long as the audio device and base unit are very close to each other, but this practice is not
recommended. Note: Bluetooth®streaming music can only be connected to Z Series base unit. See diagram below.
Pairing an Audio Device to the Z Series
A. Make sure Bluetooth®is active on the audio device. Make sure the Bluetooth®Device and discovery page is open.
B. On the Z Series Home screen the model and identification code of the unit will appear. Remember this because it will appear in the audio device
Bluetooth®list while pairing.
C. For illustration purposes we are pairing to a Model Z4 with an ID of 5267. On the Z4, navigate to the Bluetooth® Music screen. Select the Right
arrow and the window will change to “Pairing...”. Find AtlasIED Z4-5267 on the Bluetooth®discovery section of the audio device. Select it to
connect. Note: Each time a new Z Series unit is used, the audio device will have to be paired to the specific Z Series unit. Use the Model Number
and Unit ID Number of the Z Series unit to determine which unit to pair with.
D. Remember the audio level of the music from the Z Series works in conjunction with the Bluetooth®level setting in the audio device.
E. The Z Series Home screen will display the name of the audio device on the display while streaming. The audio device can also be disconnected
from the Home screen.
