APB Dynasonics MixSwitch - 4-Channel Console Switch (Touring Version)

The MixSwitch provides the ability to easily switch between a primary digital or analog console and a backup console. It can also select between headline and opening act consoles, or allow selection between FOH and DJ mixers in club applications.

Features:

• Provides ability to easily switch between a primary digital or analog console and a backup console.
• Select between headline and opening act consoles in concert/presentation situations in SWITCH mode or operate both consoles simultaneously in SUM mode.
• Allows selection between FOH and DJ mixers in club applications.
• Announce microphone input with EQ and limiting independent of primary or secondary consoles. (Master units only)
• Stereo program input with EQ and limiting for music playback independent of primary or secondary consoles. (Master units only)
• Additional stereo XLR line input provides connection of a third console or facility input. (Master units only)
• Input and Output monitoring via LED meters and audio listen system.
• Highest possible audio performance - THAT Corporation InGenius® devices used on all XLR line inputs and OutSmarts drivers on all main XLR outputs.
• Expander units (Mixswitch™-Expander or Mixswitch™-C) may be linked to a master Mixswitch™ for use wherever more line level signals require switching.

MixSwitch can be thought of as a high-quality, 4-channel A-B Switch. Four "A" Inputs and four "B" Inputs are either switched or combined into four Outputs. A1 is switched or combined into Output-1, A2 into Output-2, A3 into Output-3, and A4 into Output-4.

Inputs B1 through B4 are likewise steered to Output-1 through Output-4.

A front-panel mode-switch determines whether the A and B Inputs are selected individually (Switch) or mixed together (Sum). 2 LEDs indicate the desired Mode. A separate toggle/select switch is provided for the A and B Inputs plus an additional switch to Mute both sources.

NOTE: When unpowered, the MixSwitch will hard-bypass the A-Inputs to their respective Outputs via internal relays. When bypassed, no internal
circuitry is connected to the XLR jacks except for these relays (i.e. True-bypass mode).

Inputs are routed to their respective Outputs at Unity Gain. When A and B are both selected, they are mixed together equally, both at unity gain. The gain-staging of the MixSwitch provides the headroom needed for this function.

Although the main function of the MixSwitch is basically simple, it has to be as transparent to the audio signals as possible. To this end, it uses the latest and greatest interface chips available from THAT Corp to make connecting to the outside world as trouble-free as possible. The InGenius® input stage can easily deal with the inconsistencies of real-world balanced sources.

The OutSmarts® outputs are capable of driving long lines without distortion or instability.
