ECM 82e Mixer - Front Panel Description
INPUT SIG indicator: Lights when any Input signal, before trim, is above -25 dBu. Use to check signal flow.
INPUT OL indicator: Lights when the Input signal on any Input, before trim, is within 2 dBu of clipping. Watch this when
Selecting the Input GAIN and setting the LEVEL.
OUTPUT SIG indicator: Lights when the Mix Output signal is above -25 dBu. Use to check signal flow.
OUTPUT OL indicator: Lights when the Mix Output signal level is 2 dBu before clipping.
MIC GAIN switch: Selects b6 dB (line level), +40 dB (most mics), or +56 dB.
MIC LEVEL trim: Use a small flat screwdriver to adjust the Level from off to full on.
MIC STATUS indicators: Displays the status of the Mic gate: A flashing LED indicates the Mic is Gated On, or the Mic is
the Master Mic for this Mixer. A continuous LED indicates the Mic is the system’s Master Mic. When power is first applied,
the ECM 82e displays its DEVICE ADDRESS until it receives data from the ECB 62e. Once data is received, the ECM 82e
lights LEDs 1, 2, and 6 for about 1 second.
EXP indicator: Lights when receiving Expansion Data.
POWER indicator: Lights when the processor is operating properly.
ECM 82e Installation Notes
If Phantom Power is not required remove the top cover to the ECM 82e and disable it. See page HW Manual-10.
Always leave the RS 3 power supplies for last. Once all the wiring is completed, connect the loop thru power cables
between the ECM 82es ending at the ECB 62e. Before connecting the RS 3 make certain that it is not connected to the AC
power. See page HW Manual-11.
The ECS Expansion port is the control between the ECB 62e and the ECM 82es. Using the supplied RJ12 cable
connect the ECM 82es to the ECB 62e. Note: The ECM 82es do not use RW 232 addressing. The ECS address for the ECM
82es determines the Mic number on the ECM 82e. ECS address 1 is Mixer 1, Mics 1 thru 8. ECS address 6 is Mixer 6, Mics
41 thru 48.
