Rotel RB-970BX Stereo/Mono Power Amplifier 60 WPC — Japan

Rotel RB-970BX Stereo/Mono Power Amplifier 60 WPC — Made in Japan

A Made-in-Japan Rotel stereo power amplifier from the celebrated 970BX separates series, combining refined circuit engineering with exceptional versatility — including a bridged mono mode that unleashes 180 watts into a single channel.

The RB-970BX is the power stage to the RC-970BX preamplifier, and together they form one of the most respected budget-audiophile separates pairings of the 1990s. In stereo mode it delivers a confident 60 watts per channel into 8 ohms with vanishingly low THD of 0.03% and a damping factor of 280 — a figure that reflects tight, controlled bass response and authoritative speaker grip regardless of the load. The signal-to-noise ratio of 116 dB is exceptional and represents a level of quiet that lets the finest details in a recording come through cleanly.

The rear-panel bridged mono switch transforms the RB-970BX into a 180-watt monoblock — a compelling option for driving a centre channel, a subwoofer, or a demanding single speaker in a high-power application, all without purchasing additional hardware. Speaker load impedance is rated from 4 to 16 ohms in stereo and 8 ohms minimum in bridged mode, making it compatible with a wide range of loudspeakers. Frequency response extends to 100 kHz, preserving transient detail and air that lesser amplifiers simply discard.

This unit is in very good condition and has been thoroughly inspected and tested to confirm full functionality.
