    Crown Bus loop. In the previous example, an AMB-5 could be installed in loop 1 and use IQ address 77 because it is not an SMX-6 . A valid IQ address is any number from 1 to 250. Do not use a number higher than 250 since they are reserved for special use.

  • Page 15: Connecting The Audio Ins & Outs (Step 3)

    3.3 Connecting the Audio Ins & Outs (Step 3) IQ mixer/multiplexers have 6 mic/line inputs and 2 stack inputs. (Input 6 of the AMB-5 is dedicated for ambient sensing and is discussed in Section 3.3.2.) For output, there are two audio channels that feed two main and two auxiliary bus outputs.

  • Page 16: Amb-5 Ambient Sensing Input

    3.3.2 AMB-5 Ambient Sensing Input – In addition to its automatic mixing capabilities, the AMB-5 also has the ability to adjust the output level of Channel 1 to the ambient sound level. (Remem- – ber, Channel 2 functions only as an MPX-6 .) It does this with its sensing input (input 6).

  • Page 17: Audio Outputs

    Channel 2. Simply connect each ambient sensing microphone to one of the five regu- lar inputs of the AMB-5 and use the IQ software to assign each of them to Channel 2 only. Switch the sense input to the line-level position (L) and connect the main audio output of Channel 2 to it.

  • Page 18: Stack Inputs

    The stack in jacks (Figure 3.15) enable the audio inputs to be increased by stacking 2, 3, or more mixer/multiplexers to create a 12x2, 18x2 or wider mixer. Use 2-conductor shielded cable to route the signal from the main output of one unit to the stack input (RCA phono jack) of the second unit.

    INPUT 110 VAC Fig. 3.23 Sample Auxiliary System Wiring The solid state relay shown (Crown part number C 7308-7) can be ordered from Crown. The Aux port uses a male 3-pin mini XLR connector which is located above the DB25 connector (Figure 2.1).

    Crown Bus loop, it is recom- mended that no more than 20 units be connected to an AMB-5 or SMX-6. This is because of the tremen- dous timing demands on their microprocessors. More than 20 IQ components may cause timing problems.
