    40 seconds while keeping the audience unaware of the break. When the COUGH button is pushed, the 6000 plays from memory while the button is held in. As soon as the button is released, the 6000 automatically begins to refill the memory.
  • Page 6: Summary Product Description

    Further description of this feature is provided in chapter 5. • The DELAY numerical readout shows the length of delay time built up by the 6000 in tenth of a second incre- ments.
  • Page 7: Rear Panel View

    See chapter 4 (Installation) for details on the detachable (IEC) power cable. • The REMOTE CONTROL AND INDICATOR interface provides a way to connect to the AirTools RC-6000 or a user supplied remote control and/or indicator panel. See Appendix B for details.
  • Page 8: Installation

    Mounting in an equipment rack The 6000 occupies one rack space (1U) in a standard equipment rack with a width of 19" (48.3 cm), a depth of 7.8” (19.8 cm), and a height of 1.75” (4.45 cm). Allow at least 4” (10.16 cm) behind the unit for the protrusion of connectors.
  • Page 9: Analog Audio Output Connections

    The 6000 has been designed to operate at standard nominal broadcast signal levels of either 0 VU = +4 dBu or 0 VU = +8 dBu. To provide even more flexibility, the 6000 can also operate at -10 dBu and 0 dBu. The 6000’s operating level can be adjusted by navigating to the NOMINAL INPUT and/or OUTPUT LEVEL pages in the setup menus on the LCD display.

    The sync pulses can be used to automate the start and exit for the 6000’s delay. Another use would allow for a DJ to automate the exit of the delay to coincide with a commercial break allowing the DJ to go on break without having to wait for the delay exit in real time.

  • Page 12: Operation

    It is recommended that the 6000 remain in the OPERATE mode at all times. Typically, the 6000 would be placed in the BYPASS mode only if the unit were to malfunction. By design, a loss of mains (AC) power to the 6000 will force the 6000’s audio bypass relays to route the incoming signal directly to the 6000’s output.

  • Page 14: Troubleshooting

    • Check input signal levels and input level control settings. The input may be too low in level. If so, boost the signal from your console or input source. • Is the input signal already noisy? Listen "up stream" from the 6000 to determine if you are feeding it a clean signal.
