Pre Amplifier Rotel RC-970BX MkII is a classic analog stereo preamplifier from the 1990s, widely recognized in the high-fidelity world for its excellent balance of cost and audiophile performance. Designed around the concept of the "line-stage", this model was intentionally developed without an internal phono stage, focusing its budget entirely on high-quality line sources (such as CD players
Main Technical Features
• Total Harmonic Distortion (THD): ≤ 0.004% (20 Hz - 20 kHz).
• Frequency response: 4 Hz to 100 kHz (+0 dB, -3 dB).
• Signal-to-noise ratio: 95 dB.
• Input sensitivity/impedance: 150 mV / 24 kΩ.
• Dual pre-amplification outputs: Equipped with two RCA outputs (Pre-Out), facilitating bi-amplification setups or connection to two power amplifiers simultaneously.
• Audio inputs: 5 line inputs (CD, Tuner, Aux and two Tape loops/Tape
• Tone controls: Includes Bass and Treble controls, which can be fully bypassed to keep the signal as pure as possible.
Construction and Sound Philosophy
The RC-970BX MkII’s internal circuit was designed with fully symmetric PCBs and signal paths of equal length, minimizing the use of internal bridge wires to ensure greater consistency and sonic quality. Rotel used metal-film resistors and polystyrene/polypropylene capacitors in critical sections, powered by a highly regulated supply.
