Configuring the KAV-250a for Bridged Operation

TheKAV-250amaybe configured to operate in a bridgedmodeWhen.bridged, the amplifi- er will deliver 1000wattsto an 8 ohmload. To implementthis configuration:

1.Turn the KAV-250aoff.

2.Locatethe red switch on the backof the amplifier andslide it from the NORMAL

position to the BRIDGEDposition. The numeral2 will appearon the switch, when the switch is in the BRIDGEDposition.

Connectthe interconnect cable to the BRIDGEDinput, either balancedvia the XLRconnector or single-ended via the RCAconnector. Do not use both inputs simultaneously. Connect the speaker cables to the speakerterminals labeled BRIDGED(-)and BRIDGED(+).The lifier is nowreadyfor bridgedoperation.

KAV-250a specifications

Krell Industries has long been synonymous with high-fidelity audio equipment, and the KAV-250a amplifier stands as a testament to the company's dedication to producing premium sound solutions. This powerful amplifier is engineered to deliver exceptional performance, making it a sought-after component for audiophiles and home theater enthusiasts.

The KAV-250a is a solid-state amplifier, featuring Krell's renowned fully complementary circuit topology. This design principle ensures that both positive and negative signal paths are treated equally, resulting in a cleaner and more precise audio output. With a power rating of 250 watts per channel into 8 ohms, and an impressive 500 watts per channel into 4 ohms, the KAV-250a can easily drive a wide range of loudspeakers, from efficient models to more demanding ones.

One of the standout characteristics of the KAV-250a is its sophisticated power supply. It incorporates a massive toroidal transformer and large reservoir capacitors, which not only enhance dynamic range but also contribute to the amplifier's ability to reproduce transient sounds accurately. This robust power supply design allows for impressive control over the speakers, resulting in tight bass response and a more engaging listening experience.

The KAV-250a also features Krell's proprietary Cast technology, which is designed to minimize distortion and maximize signal fidelity. This balanced differential circuit helps maintain the integrity of the audio signal throughout the amplification process, ensuring that listeners experience music exactly as the artist intended. Additionally, the amplifier is designed with both balanced XLR and single-ended RCA inputs, providing flexible connectivity options for various audio sources.

Thermal management is another key consideration in the KAV-250a's design. The amplifier incorporates a sophisticated heat sink system that efficiently dissipates heat, ensuring reliable performance even during extended listening sessions. This attention to cooling not only protects the internal components but also contributes to the overall longevity of the unit.

In summary, the Krell KAV-250a amplifier embodies the pinnacle of audio innovation and engineering excellence. Its powerful performance, advanced technologies, and high-quality build materials position it as a leading choice for those seeking to enhance their audio system. Whether for critical listening or immersive home theater applications, the KAV-250a delivers an unparalleled audio experience that truly reflects Krell's legacy in high-end audio.
