OPERATING INSTRUCTIONS
This product serves two similar yet different functions. In
‘stereo’ mode (MONO switch and LED deactivated), it will
split two inputs into eight pairs of outputs. The A and B
INPUTS may be adjusted via the two recessed MASTER
LEVEL controls. All sixteen OUTPUTS (eight pairs) may be
set as necessary through the use of the sixteen recessed
OUTPUT level controls. The MASTER LEVEL controls adjust
the level of all OUTPUTS together without disturbing their
relative levels.
In ‘MONO’ mode, one INPUT (either) drives all sixteen
OUTPUTS, again with separate MASTER and OUTPUT
level controls. When driving both INPUTS with different
signals, the DA 216 becomes a two channel mixer. (A useful
example is combining background music with paging
signals.) The two MASTER LEVEL controls adjust the mix
ratio.
MIC LEVEL
For optimum noise performance with microphones, obtain
as much gain as possible in the Input stage of the DA 216.
1. Select the appropriate INPUT PAD to 0 dB.
2. Set the appropriate GAIN switch on the rear to 60 dB.
3. Check that the OL light (and ensuing distortion) occasion-
ally blinks with the highest expected level of signal. If it
does not come on during the loudest mic signal peaks, turn
the MASTER LEVEL control clockwise. If it is “on” more
than intermittently, turn the MASTER LEVEL control
counterclockwise. If it is still on, change the rear panel
GAIN switch to 40 dB. Adjust the MASTER LEVEL
control so the peaks barely flash the OL LED.
LINE LEVEL
In the LINE level configuration, unity gain is probably a
good place to start.
1. Select the appropriate INPUT PAD to -40 dB.
2. Set the appropriate GAIN switch on the rear to 40 dB.
3. Set the MASTER LEVELS fully clockwise, 5 o’clock.
4. Set the OUTPUT LEVELS halfway, straight up, noon.
3. Check that the OL light (and ensuing distortion) occasion-
ally blinks with the highest expected level of signal. If it
does not come on during the loudest mic signal peaks,
change the rear panel GAIN switch to 60 dB. If it is “on”
more than intermittently, turn the MASTER LEVEL
control counterclockwise so the peaks barely flash the OL
LED. Further gain control may be taken if necessary from
the OUTPUT LEVELS.

POWER SUPPLY
As noted elsewhere in this manual, Never use a power
supply with your DA 216 other than the one supplied from
the factory or an exact replacement obtained or approved
from Rane Corporation. This unit’s power supply input is
designed for an AC supply, delivering 18 volts from a center-
tapped transformer capable of supplying at least the current
demanded by this product. Using any other type of supply
may damage the product and void the warranty, which at two
years (three if you send in the warranty card) parts and labor
is worth safeguarding, don’t you think?
