DA 216 CONNECTION
When connecting the DA 216 to other components in your
system for the first time, leave the power supply for last. This
gives you a chance to make mistakes and correct them
without damage to your fragile speakers, ears and nerves.
INPUTS
The two Inputs on the DA 216 are balanced. They may
also be used in an unbalanced configuration. Use only
shielded cable for Inputs. This wire should always be two-
conductor plus shield, even for unbalanced operation.
Balanced Inputs should be connected to both the “+” and “–”
terminals. Tie the shield to chassis ground for normal use. In
some cases it may be appropriate to not connect the shield,
QUICK START
This section is provided as a convenience for those in a rush. If you are experienced with this unit or other Rane
products, these few words should help refresh your memory.
Inputs may be microphone or line level. The choice between the two is made by setting the push-buttons on the rear
of the unit near the
INPUTS
. Follow the silk-screening for proper wiring hookup.
Once
INPUTS
and
OUTPUTS
are satisfactorily connected, adjust the Input gain using a combination of the front
panel
MASTER LEVELS
and the rear panel
GAIN
switches. Set the level as high as possible without causing the
A
and
B OVERLOAD
indicators to illuminate steadily for high input levels. If 1 x 16 Mono operation is required, use only one
INPUT
and activate the
MONO
switch so the
MONO
LED illuminates. You may also use both
A
and
B INPUTS
for a
stereo signal and the DA 216 will sum the signal before distribution. If 1 x 8
STEREO
operation is chosen, select
STEREO
. This mode may also be used for two independent mono zones as a 1 x 8 mono distribution amplifier.
Never connect anything except an approved Rane power supply to the thing that looks like a telephone jack on the
rear of the DA 216.
This is an AC input and requires special attention if you do not have a power supply
exactly
like the
one that was originally packed with your unit. See the full explanation of the power supply requirements elsewhere in this
manual.
however when using Phantom Power, this ground connection
is required. For unbalanced wiring use 2 conductor shielded
cable connecting the hot side of the input cable to “+” and the
cold side to the “–”terminal. The shield must connect to the
ground terminal. For best noise rejection, run fully balanced
wiring and connect the shield at both ends to help insure
proper grounding. If a microphone is being connected to the
unit, the shield may be connected to the case of the mic as
well as to the ground terminal on the unit.
OUTPUTS
The DA 216’s OUTPUTS are balanced. The same wiring
conventions as the Inputs apply. For unbalanced OUTPUT
connections, do
not
tie the unused terminal [i.e. “–”] to GND.
