Martin Audio VIA2502 – Two-Channel Class D Rack Amplifier

Product Overview

The Martin Audio VIA2502 is a two-channel commercial Class D amplifier designed for fixed installation and portable applications where high output power in a compact rack-mount form factor is the priority. Delivering 2 x 1250 watts into 2 ohms stereo or 1 x 2500 watts bridged into 4 ohms, this rack-mount AV amplifier provides the concentrated multi-channel amplification required for driving passive loudspeakers and subwoofers in commercial AV system builds. The VIA2502 is a direct pairing candidate for Martin Audio CDD, Blackline X, and V.Series speaker systems in installations ranging from houses of worship to large commercial meeting spaces.

Product Description

The Martin Audio VIA2502 occupies the mid-tier of the VIA Series two-channel range, balancing high power output with the efficiency and physical compactness that commercial AV integrators need in rack-limited installations. Two independent channels each rated at 1250 watts into 2 ohms provide the amplification for stereo main systems, dual-zone configurations, or a combination of mains and fill circuits from a single 2U unit.

In bridged mono configuration, the VIA2502 delivers a single channel of 2500 watts into 4 ohms — making it a practical choice for subwoofer amplification or for driving high-output passive full-range cabinets that require more power than a single stereo channel can provide. This flexibility allows system designers to address a range of deployment scenarios without specifying additional amplification hardware.

Class D amplification reduces mains current draw and thermal load significantly compared to equivalent-power Class AB designs, supporting operation in equipment rooms and rack enclosures where heat management is critical for system reliability. A switch-mode power supply auto-senses mains voltage from 115 V to 230 V, enabling straightforward international deployment.

The 2U chassis includes a variable-speed front-to-back cooling fan, and comprehensive protection covering thermal overload, short-circuit, and DC fault conditions maintains full output capability in ambient temperatures up to 40°C. Front-panel signal and clip limiter LEDs give technicians real-time status visibility during system commissioning and ongoing operation.

For DSP and system control, the VIA2502 pairs directly with the Martin Audio DX0.5 loudspeaker management system for small to medium installations, or with the DX4.0 networked system controller when VU-NET software monitoring and remote control are required.

Technical Specifications

Frequently Asked Questions

How many channels does the VIA2502 provide?

The VIA2502 is a two-channel Class D amplifier. Each channel operates independently in stereo mode, or the two channels can be bridged for a single high-power mono output.

What is the output power of the VIA2502?

In stereo mode the VIA2502 delivers 2 x 1250 watts into 2 ohms. In bridged mono configuration it provides 1 x 2500 watts into 4 ohms, suitable for subwoofer amplification or high-output passive full-range cabinets.

Does the VIA2502 include onboard DSP?

The VIA2502 does not include onboard DSP. For loudspeaker management, EQ, crossover, and delay, Martin Audio recommends pairing with the DX0.5 loudspeaker management system or the DX4.0 networked system controller with VU-NET software.

Does the VIA2502 support Dante or AES/EBU digital inputs?

The VIA2502 accepts balanced analog inputs. Dante and AES/EBU digital connectivity are not native to this model. A Dante-capable DSP processor upstream would handle networked audio distribution before the analog signal reaches the amplifier.

How much rack space does the VIA2502 require?

The VIA2502 requires 2U of standard 19-inch rack space, fitting efficiently in wall-mount racks, AV closets, and main equipment rooms.

Is the VIA2502 compatible with Martin Audio CDD Series speakers?

Yes. The VIA2502 is a well-matched amplifier for Martin Audio CDD, Blackline X, and V.Series passive loudspeakers. View the full Martin Audio speaker range at creationnetworks.net/collections/martin-audio.

Can the VIA2502 drive subwoofers?

Yes. Bridged mono operation at 2500 watts into 4 ohms makes the VIA2502 a capable subwoofer amplifier for commercial installations and portable live sound builds.

What warranty does the Martin Audio VIA2502 carry?

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