Univox Loop Driver - SLS-3 / SLS-5

The all new Univox Class D Tech series with innovative features for versatile applications is here!

The super-efficient design has resulted in a very compact and light loop amplifier, compared to earlier amplifiers. At the same time they boost a higher capacity, perfectly adapted to modern SLS system design. The new Univox SLS series is based on ground-breaking Class D Tech design, where multiple parallel amplifier stages create highest possible performance. Thanks to advanced current, temperature and power protection the SLS-3/5 amplifiers are extremely durable, regardless of loop load – and even when short circuited!

When designing the new SLS-3 and SLS-5 we have changed the balance between available current and voltage. The Class D Technology combined with optimized construction for modern loop design, has resulted in strongly increased voltage capacity while keeping a high current capacity at real loads.

The first two drivers in the series, SLS-3 and SLS-5, are suitable for different room sizes and different metallic impact. Common for both models is that they can cope with higher impedances than earlier models.
