D-Link MR-8A Matrix Assign Unit Price in Pakistan (All Variants) | Skyrs

Here is the data sheet, deployment, and installation profile for the Dlink MR-8A Matrix Assign Unit series.

Dlink MR-8A Matrix Assign Unit

The Dlink MR-8A is a high-performance audio and control signal routing matrix assignment module engineered for complex, multi-zone public address, paging, and voice-alarm distributions. It serves as the primary switching hub to intelligently route inputs to multiple targeted output zones dynamically.

Equipment Variants Available for SKYRS Pakistan

To accommodate specific regional installation frameworks and architectures in Pakistan, Dlink provides the MR-8A series in three operational variants:

  • Dlink MR-8A Standard (MR-8A-STD): The foundational hardware platform relying on manual front-panel tactile selection, ideal for isolated command rooms.

  • Dlink MR-8A Logic Remote (MR-8A-LR): Integrates rear-panel logic override contacts, allowing external relays or emergency triggers to instantly override standard assignments.

  • Dlink MR-8A Smart Network (MR-8A-IP): Outfitted with digital data-bus communication interfaces to facilitate automated matrix routing commands via networked control systems.

Technical Specifications

The core architecture across all MR-8A models includes the following operational parameters:

Parameter Specification
Matrix Configuration 8 Input Channels to 8 Output Zones (Fully Assignable)
Control Logic Type Active Low (0V) triggering for override functions
Crosstalk Isolation > 75 dB at 1 kHz
Frequency Response 20 Hz to 20 kHz ($\pm$ 1 dB)
Rear Connections Detachable Euroblock / Screw Terminal blocks
Power Requirements 24V DC / 220V AC Dual Power Backup capability
Form Factor 19-inch Rack-mountable (2U Height)

Deployment and Installation

Physical integration must follow structured audio engineering standards to preserve signal isolation.

Rack Mounting Instructions

The Dlink MR-8A is built into a standard 2U, 19-inch rack-mount chassis. Fix the module securely to the vertical rails of the equipment cabinet using four M6 equipment rack screws. To minimize any induced hum from electromagnetic fields, isolate the chassis from massive high-voltage step-up transformers or power distribution units.

Signal and Control Wiring

  • Connect your source audio lines or microphone pre-amplifiers to the designated input terminal blocks on the rear panel.

  • Route the output terminals directly to the inputs of the localized zone power amplifiers.

  • For the Logic Remote variant, wire the emergency control contacts from your central system panel to the priority input block to allow automatic matrix overrides during emergencies.

Configuration and Management

Commissioning the module ensures seamless distribution behavior across all zones.

Setting Up Route Assignments

  • For manual modules, select the active matrix paths by engaging the front-panel assignment keys, locking inputs to their designated zone outputs.

  • For remote and network variants, configure the DIP switch matrix array located on the rear panel to define default fallback routing rules if control communication drops.

Matrix Level Balancing

Use the recessed trimming potentiometers on each input channel to balance line levels before broadcasting. Calibrate the input levels so that the signal peaks match the optimal input sensitivity of the connected power amplifiers without clipping the output matrix stages.

Direct Procurement and Distribution

Exclusive Authorization Notice: Every variant of the Dlink MR-8A Matrix Assign Unit series is distributed within Pakistan exclusively through SKYRS. Complete system provisioning, localized warranty management, parts availability, and engineering support are available strictly and only at SKYRS.
