Installation
1. Install the ARM motorised microphone as per separate instructions given with
the product.
2. Ensure that the Control unit power supply is
NOT
switched on until all wiring
and connections have been completed.
3. Connect the ARM motorised microphone(s) to any of the M1
– M4 motor outlet
ports on the Control unit. It does not matter which port is used as they are all
connected in parallel.
4. Connect the DSP logic signal output terminals to the DSP input socket on the
ARM-C controller. Use the Link port for daisy chaining the connection to another
ARM-C controllers.
5. Connect the microphone audio output cable to the mixer / DSP.
6. Power up the DSP and check that it has been programmed to 2.5V to
12C logic high to ARM-C to raise the microphone.
7. The DSP should be programmed to mute the microphones whilst in the upward
or downward transition to prevent unwanted motor noise pickup. Typical
transition time is approximately 3 second.
8.
Connect the 12V DC power supply to the DC +/- input terminals of the Controller
unit observing the correct polarity
9. Switching on the DC supply to the ARM-C controller will illuminate the coloured
LED on the ARM-C. The motorised microphone may initially very slowly fully
extend and then retract. This is normal as it will be auto-calibrating.
10. When a logic high is received from a DSP, the microphone will raise and remain
raised until a logic low is received.
Warning
: Warning under no circumstances connect or
disconnect an ARM microphone with the
ARM C unit powered up. Failure to do so
may cause erratic operation.
