Bosch PRA-AR616 – 600W 16-Zone Router Amplifier

The PRA-AR616 is a high-power, IP-networked router amplifier delivering 600W of reliable power to up to 16 independent zones. It features an integrated spare channel and relay-based routing for fail-safe redundancy, ensuring continuous operation during critical events.

Key Technical Highlights:

  • Nominal Output: 100V (100 VRMS) or 70V (70 VRMS) modes
  • Max Output Power: 600W (EIAJ) / RMS Power: 150W
  • Zone Support: Up to 16 zones with flexible line supervision (end-of-line devices or impedance monitoring, configurable per zone)
  • Redundancy: Integrated fail-safe design with spare channel
  • Power Input: 48 VDC (tolerance 44–60 VDC)
  • Networking: OMNEO IP for audio and control
  • Low Power Consumption and full supervision capabilities

Ideal for emergency voice alarm systems (EN 50849, BS 5839-8, ISO 7240-16) requiring high reliability, zoning flexibility, and networked control in professional installations.

EVID-S8.2TB: Product FAQs

Explore the EVID-S8.2TB surface-mount speaker pair, including audio system compatibility, outdoor use and mounting options. Find answers to common questions before planning your installation.

The Electro-Voice EVID-S8.2TB is an 8-inch two-way surface-mount speaker supplied as a black pair. It is designed for background and foreground music, paging and sound reinforcement in restaurants, retail stores, fitness clubs and hospitality venues.

Yes. Its built-in 60 W transformer supports 70 V and 100 V systems, with selectable 15 W, 30 W and 60 W taps. A 7.5 W tap is available for 70 V systems only. An 8-ohm bypass also supports low-impedance operation.

Yes. The EVID-S8.2TB has an IP54-rated enclosure for indoor and outdoor applications. Its included mounting system supports wall or ceiling installation, with 90° horizontal and 45° vertical adjustment.

The EVID-S8.2TB comes with a pre-assembled mounting system for wall or ceiling installation. It allows 90° horizontal and 45° vertical adjustment to position the speakers. Mounting brackets and a 5 mm Allen wrench are included.

ESCO (Electronic Security Company) is an official Electro-Voice dealer in Pakistan.

Built for Commercial Audio Installation

The Electro-Voice EVID-S8.2TB combines a paintable, fire-rated ABS enclosure with a zinc-plated, powder-coated grille. Connections through the wall-mounted bracket help conceal wiring, while removable locking Euroblock connectors support additional speakers on a distributed line. Its rotatable grille logo accommodates horizontal positioning, and the EVID-S range is designed to work alongside other EVID ceiling and in-wall speakers.


Paintable ABS Enclosure

The fire-rated ABS enclosure can be painted to match the installation décor. The EVID-S8.2TB comes in black RAL 9004.


Corrosion-Resistant Grille

A zinc-plated, powder-coated grille provides corrosion resistance as part of the speaker’s weather-resistant construction.


Concealed Wall-Bracket Wiring

Electrical connections pass through the wall-mounted portion of the mounting system, allowing wiring to remain hidden for a clean installation.


Quick-Attach Mounting

The ball-and-socket mounting system features quick attachment and detachment, with the support bracket integrated into the enclosure.


Locking Euroblock Connections

Removable locking 4-pin Euroblock connectors provide an additional connection option and support wiring to further speakers in a distributed line.


Protected Bypass Selection

A rear-panel switch selects transformer taps or 8-ohm bypass operation. The bypass selection is protected by a safety screw.
