  • Page 30: How To Create Zones

    How to Create Zones To establish a daisy chain correctly, first you must understand and plan your MT700 Stingray Mixer daisy-chain configuration. The order in which you place an MT700 Stingray Mixer in a chain affects whether the unit is connected to other mixers in the chain, or is split off into a separate zone.
  • Page 31 1. In this illustration, five (5) MT700 Stingray Mixers are grouped into three (3) zones, referred to here as Zones A, B, and C. Zone A is assigned to rooms 1 and 2. Zone B is assigned to rooms 3 and 4. Zone C is assigned to room 5 only. Configure the first primary mixer for room 1, and a secondary mixer without primary settings for room 2.
  • Page 32 Zone B. To convert to this configuration from the configuration represented in illustration 1, switch the MT700 Stingray Mixer for room 2 to primary status, and the mixers for rooms 3 and 5 to secondary status. Leave the mixer for room 1 set to primary.
  • Page 33 3. In this illustration, room 1 remains isolated as Zone A, rooms 2 and 3 are grouped together to form Zone B, and rooms 4 and 5 are grouped together to form Zone C. To establish Zone C, set the mixer for room 4 to primary status. Operating Manual – MT700 Stingray Phoenix Audio Technologies...
  • Page 34 Zone B, and rooms 4 and 5 are grouped together to form Zone C. To configure the zones in this way, set the MT700 Stingray Mixer for room 2 to secondary, the mixer for room 3 to primary, and leave the mixers for rooms 4 and 5 set to primary and secondary status, respectively.
  • Page 35 When daisy chaining more than one MT700 Stingray Mixer to cover multiple rooms, follow these guidelines: 1. The mixer in the first, primary position controls all other secondary mixers in the chain.

  • Page 36: Zoning Quick Reference

    Assigning secondary status to an MT700 Stingray Mixer does not erase automatically any primary settings previously programmed into it. When you assign primary status to an MT700 Stingray Mixer then later switch its status to secondary, the secondary mixer automatically inherits all settings programmed into the primary mixer.
