The Jeff Rowland Consummate II is a premium stereo preamplifier designed by Jeff Rowland Design Group, known for its Class A circuitry and exceptional audio performance. It features a line-level preamplifier with a separate regulated power supply housed in a dual chassis design. The unit offers selectable overall gain settings (6 dB, 12 dB, 18 dB, or 20 dB) and input sensitivity options to accommodate various source levels. It supports six line inputs, three of which are balanced, with both RCA and XLR connectors, and provides balanced outputs in RCA and XLR formats. The preamplifier maintains Differential Mode technology throughout its circuitry for superior signal integrity. Volume control is managed by a digitally-controlled resistor matrix with 200 precise steps, allowing user-stored level settings for each input and dual-rate attenuator adjustments. Additional features include microprocessor-controlled switching, infrared remote control with a separate remote receiver, image shift control, mono and channel cut functions, and user-controlled display shut-off. The frequency response extends from 0.05 Hz to 200 kHz (-3 dB), with a total harmonic distortion of less than 0.012% at 2.5 V RMS. Signal-to-noise ratio is 88 dB (A-weighted, referenced to 500 mV). Maximum output voltage is 8 V RMS. Input impedance is selectable among 300, 10k, or 100k ohms (unbalanced) and 600, 20k, or 200k ohms (balanced). Output impedance is selectable between 150 or 300 ohms (unbalanced) and 300 or 600 ohms (balanced). The unit measures approximately 13.75" W x 15" D x 2.65" H for the preamplifier chassis, with the power supply in a separate chassis of the same size, and weighs about 28 lbs (12.8 kg) including the power supply. Originally It remains highly regarded for its sonic quality and build excellence among audiophiles.
