  • Notes
  • The HY5 has rapidly established a position in the WORLD as the sole hybrid pre-amplifier to contain all feedback and equalization networks within an integrated pre-amplifier circuit.

    Supplied with the HY5 are two stabilizing capacitors and with the addition of volume, treble, and bass potentiometers it is ready for use.

    Internally the HY5 provides equalization for almost every conceivable input, the desired function is achieved by using a multi-way switch or by direct interconnection.

     Two distinctive features of the HY5 are its inbuilt stabilization circuit, allowing it to be run off any unregulated power supply from 16-25 Volts and a balance circuit which, when linked by a balance control to a second HY5, forms a complete stereo pre-amplifier.

    Specifically and critically designed to meet exacting Hi-Fi standards, the HY5 combines extremely low noise with a high overload capability.

    When used in conjunction with the HY41 and PSU45 forms a completely integrated system monophonic preamplifier that only needs the application of the volume and tone controls and the switch to choose the desired input.
