Martin Audio VIA5002 – Two-Channel High-Power Class D Amplifier

Product Overview

The Martin Audio VIA5002 is a high-power two-channel commercial Class D amplifier engineered for subwoofer amplification and high-output passive speaker systems in commercial and portable sound installations. Delivering 2 x 2500 watts into 4 ohms or 2 x 1600 watts into 8 ohms, this rack-mount power amplifier provides the concentrated output needed for demanding low-frequency and full-range applications in houses of worship, auditoriums, and live sound environments. As the most powerful two-channel model in the VIA Series, the VIA5002 is the preferred choice for system designers specifying high-headroom commercial AV amplifier solutions.

Product Description

The Martin Audio VIA5002 leads the two-channel VIA Series lineup, combining maximum power density with the compact 2U rack-mount form factor and high operational reliability that commercial AV integrators require. With 2 x 2500 watts into 4 ohms, the VIA5002 delivers the output headroom to drive high-excursion passive subwoofers, high-power full-range cabinets, and high-sensitivity loudspeaker arrays to their rated capacity under extended operating conditions.

At 2 x 1600 watts into 8 ohms, the VIA5002 is equally suited to driving 8-ohm passive cabinets common in installed commercial AV applications. This dual impedance flexibility allows system designers to specify the VIA5002 across a range of loudspeaker systems without compromising available headroom or requiring additional amplification stages.

The Class D amplification topology minimizes power dissipation at rated output, reducing heat buildup in rack enclosures and equipment rooms. The switch-mode power supply maintains stable output across the global mains range of 115 V to 230 V with auto-sensing, simplifying international and multi-site deployment. Total output power of 5000 watts is delivered in a chassis light enough to reduce rack structural loading relative to equivalent linear-topology designs.

Variable-speed front-to-back cooling manages thermal load quietly during lower-demand periods and scales fan speed as power output increases. Comprehensive protection circuitry monitors thermal, short-circuit, and DC fault conditions continuously, maintaining full output capability in ambient temperatures up to 40°C. Front-panel signal and clip limiter LEDs provide the visibility technicians need during commissioning and routine system checks.

For upstream DSP integration, the VIA5002 pairs with the Martin Audio DX0.5 loudspeaker management system for installations requiring crossover and EQ, or with the DX4.0 networked system controller for full VU-NET software monitoring and network-based system management.

Technical Specifications

Frequently Asked Questions

How many channels does the VIA5002 provide?

The VIA5002 is a two-channel Class D amplifier. Both channels operate at full rated power simultaneously, making it suitable for stereo subwoofer arrays, dual-zone high-power applications, and high-output two-channel system builds.

What is the output power of the VIA5002?

The VIA5002 delivers 2 x 2500 watts into 4 ohms or 2 x 1600 watts into 8 ohms. This is the highest-rated two-channel model in the VIA Series and is intended for subwoofer amplification and high-output passive speaker systems.

Does the VIA5002 include onboard DSP?

The VIA5002 does not include onboard DSP processing. For loudspeaker management including crossover, EQ, delay, and limiting, Martin Audio recommends pairing with the DX0.5 loudspeaker management system or the DX4.0 networked system controller for VU-NET software control.

Does the VIA5002 support Dante or AES/EBU digital inputs?

The VIA5002 accepts balanced analog inputs. Dante and AES/EBU digital connectivity are not native to this model. For networked audio, a Dante-capable upstream processor such as the Martin Audio DX4.0 would handle signal routing and conversion before the analog feed reaches the VIA5002.

How much rack space does the VIA5002 require?

The VIA5002 occupies 2U of standard 19-inch rack space. For a 5000 W two-channel commercial power amplifier, this is an exceptionally compact physical footprint.

Is the VIA5002 well-suited for subwoofer amplification?

Yes. The VIA5002 is specifically noted by Martin Audio for subwoofer applications. At 2500 W per channel into 4 ohms, it provides the sustained high-current output that large-format passive subwoofer systems demand in commercial and live sound environments.

Is the VIA5002 compatible with Martin Audio CDD Series and other passive speakers?

Yes, though the VIA5002 is most commonly specified for subwoofer or high-output applications given its power rating. For full-range CDD, Blackline X, and V.Series speaker system combinations, visit creationnetworks.net/collections/martin-audio.

What warranty does the Martin Audio VIA5002 carry?

Martin Audio products purchased through Creation Networks are covered by Martin Audio's standard manufacturer warranty. Contact creationnetworks.net for warranty registration assistance and support.
