1. Use second drain wire if available or add an extra section of wire Standard cables are generally constructed using a male connector at one end and a female connector at the other end This allows several cables to be interconnected to create longer cable runs Audiocom master stations speaker stations and belt packs also typically provide both a male and female Neutrik connector for each intercom channel This permits loop through connection of several intercom stations using the standard cables Audiocom power supplies use a 3 pin male Neutrik connector for each channel Audiocom wallplates use male Neutrik connectors FIGURE 3 Cable Wiring Diagrams for Audiocom Applications Desktop or Rackmount Installation PS 2001L Power Supply Combine Isolate Switch set to Isolate Pa 1 1 channel cable 2 2 channel cable Y cable 0 0 o US2000A e S e o 2000 Master Station To all stations on channel 1 BP 1000 A o mo 00 G HEADSET LINES BP 1000 5 o o HEADSET A o o ao ch oo oye gt HEADSET LINES BP 2000 oo Ono Gi 00 ofo a HEADSET LINES BP 1000 oo L oo s HEADSET LINES FIGURE 4 Typical connections using a single PS 2001L Power Supply to power two channels To all stations on channel 2 BP 1000 1 Gs O HEADSET BP 1000 1 o o HEADSET Note A JB 2 Junction Box may be used ins2.
