MG82CX/MG102C
38
2-18 Digital effect (MG82CX)
Set each volume of CH1, MASTER and DIGITAL EFFECT as follows,
• CH INPUT (CH1)
EFFECT level control Maximum
CH level control Maximum
• MASTER
STEREO level control Maximum
• DIGITAL EFFECT
DIGITAL EFFECT switch ON (lighting)
PROGRAM select switch PROGRAM 16
PARAMETER control Minimum
EFFECT RTN level control Maximum
* Set the other volumes to Minimum or Center and turn off the switches.
* Turn the PAN control clockwise or counterclockwise fully.
Input the signal of –50.0 dBu to the MIC input of CH1.
Then, check that the output level at the ST OUT L, R is –10.0 dBu or more.
Short the input with 150 ohms resistor and set the EFFECT level control and the CH level control of CH1 to Minimum.
Then, check that the noise level at the ST OUT L, R is –57.0 dBu or less.
* Use the 12.7 kHz, –6 dB/octave Low Pass Filter when measuring the noise level.
3. Others
Execute each test with controls set effective.
3-1 Effect (MG82CX only)
Check that each program works properly when the programs 1, 6, 11, and 16 are set with the PROGRAM switch.
Check that the output sound is changed properly for each program when the PARAMETER controls are operated.
Check that there is no abnormal noise when the PROGRAM switch is switched.
3-2 PHANTOM power supply
Connect the resistor of 10 kohms (1 W or more) between the 1 pin and 2 pin of the MIC input and short circuit
between the 2 pin and 3 pin.
Check that the voltage between the 1 pin and 2 pin is between +33.6 V and +37.3 V when the PHANTOM switch is
turned on (LED should light).
