& V250, V35 specifications

The Bogen V35 and V250 are two high-performance public address (PA) systems designed to meet the demands of various venues and applications. Known for their robust features and advanced technologies, both models provide exceptional audio quality, versatility, and ease of use.

The Bogen V35 is a compact yet powerful amplifier, catering to mid-sized venues such as schools, conference rooms, and places of worship. It offers an output power of 35 watts, making it ideal for announcements, background music, and public speeches. One of its main features is the built-in digital signal processing (DSP), which enhances sound clarity and enables users to tailor audio to specific needs. The V35 also supports various input options, including microphone, line-level, and RCA connections, allowing for multiple audio sources to be integrated effortlessly.

The V250, on the other hand, is engineered for larger venues and higher output requirements, boasting an impressive 250 watts of power. This model is particularly suitable for auditoriums, large conference halls, and outdoor events. The V250 is equipped with advanced features such as feedback suppression and automatic gain control, which help maintain consistent audio quality regardless of the environment or speaker proximity. Like the V35, the V250 includes multiple input channels, allowing for comprehensive audio mixing capabilities.

Both the V35 and V250 utilize Bogen's innovative thermal protection system, which ensures the amplifiers remain cool even during extended use, promoting longevity and reliability. Additionally, these models are designed with user-friendly interfaces, featuring clear knobs and indicators for adjusting volume, bass, and treble with ease.

In terms of build quality, both amplifiers are housed in durable metal enclosures, making them suitable for both permanent installations and portable use. Their sleek design means they can easily fit into any environment without being an eyesore.

In conclusion, the Bogen V35 and V250 stand out for their versatile features, advanced technologies, and high-quality audio output, making them excellent choices for a range of public address applications. Whether for small gatherings or large-scale events, these amplifiers deliver effective sound solutions tailored to the needs of users.
