  • Amp 1 output Ch 2 goes to +/- 2 on the "AMP 1&2" NL8 and "AMP 1" NL4
  • Amp 2 output Ch 1 goes to +/- 3 on the "AMP 1&2" NL8 and +/- 1 on the "AMP 2" NL4
  • Amp 2 output Ch 2 goes to +/- 4 on the "AMP 1&2" NL8 and +/- 2 on the "AMP 2" NL4
  • Amp 3 output Ch 1 goes to +/- 1 on the "AMP 3&4" NL8 and +/- 1 on the "AMP 3" NL4
  • Amp 3 output Ch 2 goes to +/- 2 on the "AMP 3&4" NL8 and +/- 2 on the "AMP 3" NL4
  • Amp 4 output Ch 1 goes to +/- 3 on the "AMP 3&4" NL8 and +/- 1 on the "AMP 4" NL4
  • Amp 4 output Ch 2 goes to +/- 4 on the "AMP 3&4" NL8 and +/- 2 on the "AMP 4" NL4
  • Amp 5 output Ch 1 goes to +/- 1 on the  "AMP 5" NL4
  • Amp 5 output Ch 2 goes to +/- 2 on the  "AMP 5" NL4

NOTES

  • The NL8 outputs are "3 way outs" meant for the VTX A12 speaker and the Vertec 4888 speakers.
    • +/- 1 and +/- 2 are for the LF drivers
    • +/- 3 is for the MF drivers
    • +/- 4 is for the HF drivers
  • The NL4 outputs are used mainly for the G28 subs woofers.
    • NO MORE THAN 2 G28s PER NL4
    • AMP 5 is the default amp for the subs
  • "AMP 1&2" NL8 is wired in parallel with "AMP 1" AND "AMP 2" NL4s; "AMP 3&4" NL8 is wired in parallel with "AMP 3" AND "AMP 4" NL4s
    • IF USING THE NL8s, DO NOT USE THE NL4s THAT ARE WIRED IN PARALLEL WITH THEM, AND VICE VERSA.

POWER

  • CIRCUIT 1 is powering Amps 1&2
  • CIRCUIT 2 is powering Amps 3&4
  • CIRCUIT 3 is powering Amp 5

CAUTION: This amp rack will not have enough power to run concert level audio with the Mains and Subs together.  If needing concert level audio, contact Audio Department Head about options to get more power.

The "HiQnet" ports go to a network switch in which all the amps are networked into.  This is for easier setup for Performance Manager.
