The Concerto Preamplifier reflects the sum total knowledge gained from nearly thirty years of Jeff Rowland Design Group's amplifier and preamplifier design experience. Sonically, the Concerto rests among equals amidst the highest-quality units available.
The Concerto offers a simple feature set for ease of use with a large, high-visibility display for volume level indication. The entire chassis is milled from a solid, massive block of 6061 aluminum to provide a vibration-free and EMI resistant enclosure for sensitive audio circuitry.
Dual, balanced line-level outputs, transformer-coupled balanced and unbalanced inputs, and preamp bypass inputs allow unprecedented compatibility with virtually any A/V component in both stereo and multi-channel installations.
The most commonly used features of the preamplifier can be controlled with an easy to use, six function, hand-held IR remote control. A dual rate volume control allows precision level adjustments over nearly a 100 dB range. The volume control incorporates a permanently noiseless optical encoder that will always maintain its tactile feel, accuracy, and channel balance at all settings.
Modern Instrumentation amplifier circuitry allows an exceptionally low noise floor, revealing previously obscured information, detail, and microdynamics from all program material.
The Concerto is equally capable as the centerpiece of a quality two-channel audio system or a complex, cost-no-object home entertainment system.
