7) Set the Level Match for each channel. Press the UP button to advance to the Level Match screen then
press SELECT repeatedly to move the cursor to the Value field. Press the UP and DOWN buttons to set the
Level Match to the desired value.
(Note: If the AutoSet procedure has already been performed, the Level Match will already be set and will not
require readjustment in most cases. Level Match may be "fine tuned" here if necessary.) Level Match inserts
a correction factor to the microprocessor so that the system access of all the channels is the same.
8) Select the maximum attenuation using the "Max Attenuation" function. The choice of attenuation is made
based on the total number of microphones used with the DC1(s). If the total number of microphones is 10 or
less, 10dB of attenuation is adequate. 10 to 32 total microphones requires 15dB of attenuation. 33 or more
total microphones requires 20dB of attenuation. The exact amount of attenuation necessary may be calculated
as 10 * Log
10
(Number of Microphones) dB. More attenuation than the minimum may be used if desired for the
particular application. No ill effects occur if less than the recommended off attenuation is used. Repeat for all
channels.
9) Select the Auto Gain Skew value, or OFF if Auto Gain Skew is not desired.
10) Save the settings. After all desired selections have been made, push the SAVE button to store all chosen
values to non-volatile memory. The following will momentarily be displayed:
All Values Saved .
Note that the DC1 has 3 memory positions, so three complete setups of all function values may be saved in
non-volatile memory. In this way, settings optimized for different applications may be simultaneously saved.
11) Switch the DC1 back to the OPERATE mode. Press the MODE button until the NEW SETTING LED goes
out and the OPERATE LED comes on. Note that on power up, the DC1 will default to the operate mode and
the Auto Skew screen.
