Vertec 4886/4883 System

The Vertec 4886s are a passive speaker, meaning they only require a single amp channel to run.  They have an A/B switch on the back so that when using the Orange outputs on the back of the rack, you can run up 8 4886s on a single NL4.  The 4883s are bi-amped subs, meaning they take 2 channels of amplification to run.

INPUT WIRING

• The presets on these racks have been reworked that you can keep the wiring inside the same and still have a stereo system when using the Analog 1 and Analog 2 inputs at the top of the rack.
• If the system is not working in Stereo from the onset, make sure the wiring in the rack matches the picture above.
• NOTE: There are two sets of presets for the 4886s in Array, one set that is labeled "NL4" (Presets 2-4) and ones that are labeled "NL8"(Presets 34-36) that correspond to which outputs you are going to use to send to you PA.
  • The NL4 preset is the most likely to be used.  Use when flying the 4886s and ground stacking the 4883s.
  • The NL8 is used when running the the 4886s and 4883s with a single NL8 run i.e. you are flying the Subs with the Mains.

OUTPUT WIRING

Below a couple of examples on how to wire the 4886s and 4883s with the VRack 12000HD.

6 4886s Hanging and 2 4883s Ground Stacked a Side

Wired with NL4

 

• The 4886s come out of Orange Outputs 1&2 (Left & Right respectfully) 
  
• The 4883s (Subwoofers) come out of the Blue Output 3 on both Ch 1 and Ch 2
  
  • The Blue Outputs are wired in parallel, so both +/- 1 and 2 are being powered by a single amp channel

2 4883s and 6 4886s Hanging Together

Wired with NL8

• Input wiring is the same as the previous example.
• Both stacks using a single NL8 home run with NL8 Jumpers
  • NL8 line will carry all channels needed to run whole stack.

NOTICE: The A/B switches on the back of the 4886s are very important.  Make sure the switches are set correctly to avoid overloading the amplifiers.
