Product Description

    Details

    Krell Vanguard Vanguard Integrated Stereo Amplifier The Vanguard incorporates a 200-watt-per channel amplifier and a Class A preamplifier, enclosed in a chassis that borrows its design and construction from the new Krell Foundation preamp/processor, Connect stream player, Illusion preamp and iBias amplifiers. An optional, field-installable digital module with USB, HDMI, coaxial, and optical inputs as well as Ethernet audio and Bluetooth streaming will also be available. The Vanguard’s amplifier incorporates a massive power supply with a 750 VA toroidal transformer and 80,000 microfarads of storage capacitance. The tremendous amount of energy on tap provides 200 watts per channel into 8 ohms and 400 watts into 4 ohms. Two quiet, thermostatically controlled fans permit the use of a surprisingly compact chassis. The preamplifier section of the Vanguard borrows its balanced, fully discrete Class A circuit concepts from Krell’s top-of-the-line Illusion preamplifiers. Krell’s Current Mode technology is employed to assure unequaled signal bandwidth, easily enough to handle the latest high-resolution PCM and DSD audio sources without impacting high-frequency response and detail. Packed with many of Krell’s most musical-sounding technologies, the elegant chassis is living-room-friendly. Yet it has enough power to achieve incredible, lifelike dynamics with any speaker. The front-panel menu system provides configuration features such as input naming and input trim. Theater Throughput mode lets the Vanguard serve as the core of a surround-sound system without sacrificing two-channel sound quality. Analog Inputs include three stereo RCA and one stereo balanced XLR. High-quality WBT speaker cable terminals provide a secure, electrically ideal connection. The Vanguard also offers features that make it perfect for custom installation, such as 3.5mm jacks for IR input and 12-volt trigger input and output, as well as optional rack-mount ears. Additionally, the unit can be controlled with home automation systems through its Ethernet connection.
