Martin Audio - VIA5004 Ampli 4 x 450W / 8 ohms

The Martin Audio VIA5004 amplifier is a 4-channel Class D amplifier designed to manage complete systems with a single machine. It delivers 4 x 450 W into 8 ohms, with the option of increasing to 800 W into 4 ohms or 1250 W into 2 ohms, so you can easily adapt your configuration to suit the speakers you're using. You can also use it in bridge mode to obtain 2 x 2500 W at 4 ohms, practical for powering subs or more demanding loads.

Its design also allows for a 3-channel configuration, particularly useful for 3-way systems such as some TH Series speakers. This simplifies wiring and reduces the number of amps needed in your rack.
Class D amplification reduces power consumption while maintaining a good reserve of power when the system is under strain. The switch-mode power supply automatically accepts voltages from 100 to 240 V, making it easy to use on different sites. Cooling is provided by variable-speed fans with front-to-rear airflow, suitable for rack integration.

Connections include XLR inputs and outputs for chaining signals, and Speakon outputs for reliable connection to your loudspeakers. Output remains stable with a wide frequency response and good signal control, even at high levels.

Integrated protections continuously monitor temperature, load and any anomalies to ensure the safety of your installation. Weighing in at just 2U and 10 kg, it's easy to transport and can be used in both fixed and mobile installations.

This model is ideal for use in bars, clubs, places of worship, halls or live events. Combined with a suitable processor, you can fine-tune your system and exploit all the power available according to your setup.
