AB - Master

With T.S.S. True - Switching - System

True Switching A/B Selector

Switches 1 input signal between 2 different outputs or 2 inputs alternately to 1 output. Typical applications would be the selection between 2 different amps with one guitar, or playing two guitars alternately over the same amplifier. The TSS system is also employed here to assure completely unmodified instrument signals.

Individual "ground lift" switches for each in- and output can prevent most common "hum problems" if necessary. The "Auto Mute" feature shorts the unused output to ground automatically to stop external amplifier noise from creeping into your system. Bright LEDs indicate the active channel. Remote control can easily be provided by attaching a standard footswitch (latched type) or Midi switcher.

  • Features:

  • - Equipped with high-end audio relays
    - DC input- and -output jacks
    - low power consumption
    - connectable housings - 4 units are < 19", 1RU
  • Power:

  • - electr. stabilized power supply 9V..12V DC, min. 100 mA, 2.1mm plug, tip neg.

Loop - Master

With T.S.S. True - Switching - System

True Switching Loop Selector


This unit will loop any effect into your system by simple operation of a switch. It can easily be remote-controlled by attaching a standard footswitch (latched type) or Midi switcher. Bright LEDs indicate, whether the loop is presently active or bypassed.

The Loop-Master features the ingenious Nobels TSS switching system to prevent any possible signal degradation in bypass mode. This allows for the use of even noisy vintage effects, that commonly exhibit the phenomenon of "tonesucking" when bypassed.

  • Features:

  • - Equipped with high-end audio relays
    - DC input- and -output jacks
    - low power consumption
    - connectable housings - 4 units are < 19", 1RU
  • Power:

  • - electr. stabilized power supply 9V..12V DC, min. 100 mA, 2.1mm plug, tip neg.

Split - Master

Active 4x2 or 2x4 Signal Splitter

A universal high quality signal splitter for instrument and line level applications, that allows the user to distribute up to 4 independent audio signals to several devices each. The buffered outputs prevent any possible signal degradation or interference between them.

The unit features 4 inputs and 8 outputs that can be utilized in different combinations. Depending on which inputs are used it is possible to route either 2 mono signals (i.e. one stereo signal) to 4 outputs each or 4 mono signals to 2 outputs each. It is also possible to use a "mixed mode" with 1 mono input to 4 and 2 mono inputs to 2 outputs each.

  • Features:

  • - DC input- and -output jacks
    - low power consumption
    - connectable housings - 4 units are < 19", 1RU
  • Power:

  • - Electr. stabilized power supply 9V..12V DC, min. 100 mA, 2.1mm plug, tip neg.
