Shipping info

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.

The module has these controls and in/outputs available:

  • 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

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.

  • Width: 4HP
  • Depth: 45mm
  • Power: 20 mA +12V / 20 mA -12V / 0 mA 5V

These times are estimates and are not guaranteed. Delivery may occasionally take a little longer due to customs processing, local conditions, or carrier delays.

Dispatch times

Orders placed before 15:00 CET (Central European Time) on a working day are normally dispatched the same day. Orders placed after 15:00 CET, or on weekends and public holidays, will be dispatched on the next working day.

If you have an urgent order, please email us at info@signalsounds.eu before placing your order and we'll do our best to accommodate you.

Pre-orders

If a product is listed as a pre-order, it means we've ordered it from the supplier but it's not physically in stock yet. The product listing will include an estimated shipping date based on the best information we have from the supplier, but do bear in mind this is subject to change and is not a guaranteed date.

If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch at info@signalsounds.eu if you have questions.
