A-105-2 24dB SSI Low Pass Filter

Module A-105-2 is a voltage controlled low pass filter with 24dB/octave slope. It is the successor of the A-105 which had to be discontinued because the obsolete SSM2044 filter circuit. The A-105-2 is based on the SSI2144 which is in turn the successor circuit of the SSM2044. The features of both modules are nearly the same. The main difference is the clearly reduced front panel width of the A-105-2 (4HP instead of 8HP) and the associated changes of the controls and sockets positions. In addition the A-105-2 is equipped with 2 audio inputs.

  • Technical notes:

    Frequency range: about 15Hz ... 15 kHz

    Resonance up to self oscillation

    Max. input voltage at Input 2 without clipping/distortion: about 15Vpp

    Max. output voltage without clipping/distortion: about 15Vpp

    The signals of both inputs are mixed before they are processed by the filter. This saves an external mixer for small setups.

  • Control Frequ: manual frequency control

    Control FCV2: attenuator for the frequency control voltage applied to socket FCV2

    Control Q: manual resonance control

    Control QCV: attenuator for the resonance control voltage applied to socket QCV

    Control Input 1 Level: attenuator for the audio input signal applied to socket Input 1

  • Socket Input 1: audio input 1 (with attenuator)

    Socket Input 2: audio input 2 (without attenuator)

    Socket FCV1: frequency control voltage 1 (without attenuator, about 1V/oct scale)

    Socket FCV2: frequency control voltage 2 (with attenuator)

    Socket QCV: resonance control voltage (with attenuator)

    Socket Out: audio output
