  • Annotazioni
  • A 2 x 70 watt Hi-Fi stereo power amplifier. On the front, a press button for Power and a Power on indicator and a Bridged Mono indicator. On the back, Left and Right input RCA sockets for connection to a preamplifier. In order to use the RB-971 Mk II in bridged mode, three “jumper” connectors inside the amplifier must be moved from one set of pins to another. In bridged mode the Left and Right channels are bridged into a into a single mono amplifier and the cable from the preamplifier output is connected to the Left input RCA socket. Four terminals to connect one stereo pair of loudspeakers, or to one loudspeaker in bridged mode where the wires to the loudspeaker are connected to the positive terminals of the left and right channels.

    Continuous Power Output :
    70 watts per channel, min. RMS both channels driven into 8Ω
    from 20Hz to 20kHz with < 0.03% Total Harmonic Distortion
    95 watts per channel, min. RMS both channels driven into 4Ω
    from 20Hz to 20kHz with < 0.05% Total Harmonic Distortion
    Bridged Mono Power Output :
    180 watts mono, min. RMS driven into 8Ω
    from 20Hz to 20kHz with < 0.1% Total Harmonic Distortion
    Total Harmonic Distortion ......:  < 0.03%
    Intermodulation Distortion .... :  < 0.03% (60Hz :7kHz, 4:1)
    Damping Factor ................... :  500 (20Hz - 20kHz, 8Ω)
    Speaker load impedance  .....:  4Ω minimum Stereo, 8Ω minimum bridged mode
    Input Sensitivity/Impedance ..:  1.0V/33kΩ
    Frequency Response ...........:  10Hz - 100kHz, ±1dB
    Signal to Noise Ratio ............:  116dB (IHF, A Network)
    Power Consumption .............:  250 watts
