1 Overview
Appropriate for small projects to the biggest installations, the VoiceArrest sound
masking system is simple and highly versatile, without compromise on sound masking
performance and quality.
This user manual describes in details how to install the VoiceArrest rack-mount series
of controllers.
The rack-mount series of controller oers powerful ampliers ideal for larger sound
masking systems.
The VAR-96-8CH controller features powerful ampliers capable of driving up to 12
speakers per zone for a total of 96 loudspeaker per controller.
The VAR-CTLV2 controller is a line-level version of the VAR-96-8CH which requires
external ampliers to drive loudspeakers.
Both the VAR-96-8CH and VAR-CTLV2 oer an intuitive touch-screen interface for
quick adjustments.

4 Installation
4.1 Safety Instructions
• Read and keep these instructions.
• Heed all warnings and follow all instructions contained within this manual.
• Install in accordance with the manufacturer’s instructions.
• Clean only with dry cloth.
• Do not install near water.
• Do not block any ventilation openings.
• Do not install near any heat sources such as radiators, heat registers, stoves, or
other apparatus (including ampliers) that produce heat.
• Use the power cord with sealed mains plug appropriate for your local main supply
as provided with the equipment. If the provided plug does not t into you outlet
contact the manufacturer.
• Protect the power cord from being walked on or pinched particularly at plugs,
convenience receptacles, and the point where they exit from the apparatus.
• Only use attachments and accessories specied by the manufacturer.
• Refer all servicing to qualied service personnel. Servicing is required when the
apparatus has been damaged in any way, such as when 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.
• Operate the product only with the voltage specied on the unit. Fire and/or
electric shock may result if a higher voltage is used.
• Do not modify, kink, or cut the power cord. Do not place the power cord in close
proximity to heaters and do not place heavy objects on the power cord and/or the
product itself, doing so may result in re or electrical shock.
• Be sure the installation of this product is stable, avoid slanted surfaces as the
product may fall and cause injury, property damage, electrocution and/or re.
• Do not open the cover.

4.2 Securing the Controller
The VoiceArrest controllers with a rack-mount form factor are designed
to be installed in a standard 19” rack-mount cabinet using the provided
mounting brackets. The enclosures are 1.7” high and occupy a 1U space.
It’s recommended to leave some room above each controller to allow air
circulation.
4.3 Powering the Controller
The rack-mount controllers are delivered with their own power-supply
units. Only one controller can be powered per power-supply unit. Place the
power-supply in the dedicated bay.

4.4 Connecting Loudspeakers
4.4.1 VAR-96-8CH
Sound masking loudspeakers are typically suspended from the deck, above the
acoustic ceiling tiles. Dierent types of loudspeaker can be used depending on the
installation requirement. Refer to the loudspeaker user guide for more information.
Use 18-AWG 2-Conductors wire to connect the loudspeakers to the VoiceArrest
controller. Use plenum rated cable and follow local regulations. Typical wire will
be 18/2 FT4. All speakers on a channel are connected in parallel using twist-on
connectors.
Refer to the Design Guidelines Handbook for guidelines on loudspeaker layout and
zone denition according to room characteristics.

4.4.2 VAR-CTLV2
The VAR-CTLV2 does not include power ampliers. External ampliers must be used
to drive loudspeakers. The recommended power amplier is the Ashly TRA-2150.
Using the VAR-CTLV2 paired with an external amplier allows to increase the number
of speakers. Note that the output level may be reduced due to a lower sensitivity tap
setting on the speakers.

4.5 Connecting Active Volume Control Sensors
The best location to put the active sound masking volume control sensor is through
the acoustic tile. Sensors must be installed, if possible, in a central position to catch
most of the noise in the zone.
Connect the sensor with 22 AWG shielded cable and BCN connectors. Up to 6 sensors
can be connected on the active input. Connect the shield wire on the negative
terminal on the controller end only, do not connect the shield on the sensor terminal
and let it oat. If many sensors are used, connect the shield between them to ensure
continuity.
Note: When a long cable is used, it’s recommended to run the cable separate from the speaker lines. A minimal
distance on 12 inches between the speaker wires and the volume control cable is recommended.
Refer to the Active Control Sensor User Guide for more information on Active Control.
Refer to the Design Guidelines Handbook for more information on sensor layout.
