Apogee DA-16 User's Guide
Calibration Mode
When the DA-16 is powered up, enter Global Calibration Mode by pressing and holding the CH SET button
until the 16 channel LEDs start to flash. With all channels flashing, press the UP and DOWN buttons to adjust
the level on all channels at once. NOTE: individually-adjusted offsets on different channels are maintained and
adjusted together in global calibration mode.
By pressing the CH SET button again, a single LED will flash representing the individual channel that is now
ready to be calibrated. Note that this channel will be the last individual channel that was adjusted by the user,
unless default values were just restored (in which case it will be channel 1). Cycle through the channels by
repeatedly pressing the CH SET button to select the channel you wish to calibrate. Using the UP and DOWN
buttons, adjust the level for that particular channel.
By holding down the UP or DOWN button in either mode, the unit will auto-increment to make calibration quick-
er. To better accommodate extreme adjustments, the auto-increment speed will increase by eight times after
holding the direction button down for two seconds. Note that short UP/DOWN button presses are used for fine
adjustment.
When you have completed adjustments, exit Calibration Mode by holding down the CH SET button until there
are no periodic, flashing LEDs. Note that calibration values will not be saved unless calibration mode is prop-
erly exited in this way.
Restoring Default Values
Hold the SYNC (CH SET) button down while powering up. Notice that the startup LED sequence is inverted to
indicate that the unit is booting with default calibration values. Default calibration is set to +4dBu = –16dBFS.
Internal Settings
The following information is provided for authorized technicians only and is not intended for use by
the user. Adjustment of internal settings by non-authorized persons will void the warranty. Technicians are
expected to follow appropriate ESD practices.
Voltage setting
With the power cord disconnected, use a coin or flathead screwdriver to align the desired voltage setting with
the white mark at the perimeter of the selector switch. Ensure that you are using the proper fuse – see below.
Fuses
CAUTION For protection against risk of fire, replace only with same type and rating of fuse: 100/120V~
operation: 250V, 800mA, T (Slow Blow); 220/240V~ operation: 250V, 400mA, T (Slow Blow).
