Name: VIA5004
Rating: 4.7 (23 reviews)

The VIA5004 is an advanced 4-channel power amplifier which combines high power density with superb audio performance in a lightweight, cost-effective package. Delivering 4 x 1250 watts into 2 ohms, or 2 x 2500 watts into 4 ohms bridged, it is ideal for powering Blackline X, CDD and V.Series systems in small to medium-scale installations and portable sound applications. It can also be configured for 3-channel operation, for perfect compatibility with TH Series 3-way systems.

Features

Four channels of efficient Class D amplification
5000 Watts total power output
2U rack height
Exceptionally lightweight
Switch mode power supply
Variable speed cooling fan with front-to-back airflow
Global mains operation, 115V to 230V auto-sensing
Comprehensive protection systems
Signal and clip limiter LEDs

Applications

Small to medium-scale installations
Portable sound and stage monitoring
Hotels, restaurants and bars
Houses of Worship and auditoriums
Educational facilities
Live music and dance clubs
Mobile DJ’s

Its high efficiency design reduces the energy drawn from the mains supply and ensures the power reserves needed to deliver superb sound in demanding environments with reliability and ease.

Comprehensive protection functions continuously monitor its performance to maintain safe operating conditions and full output capability in ambient temperatures up to 40°C.

For a wide variety of installations and portable situations, the VIA5004 ideally partnered with the Martin Audio DX0.4 or DX0.6 system processor. Larger installations will benefit from use with the DX4.0 with its on-board network capability and proprietary VU-NET software control.
