DA 216a REAR PANEL
IMPORTANT NOTE
CHASSIS GROUNDING
The DA 216a is supplied with an external power supply (the RS 1). This power supply does not ground the unit to the power line
ground. On the rear chassis a #6-32 screw is provided to allow for attachment of the grounding wire. This chassis ground point must
be connected to earth ground either through another product, which utilizes a three-prong grounded AC power cord, or by attaching
the wire to a known earth ground (such as the screw on a grounded AC outlet).
1
INPUT terminals:
Attach either Microphone or Line-level sources here. Connect balanced sources to the respective “+” and
“–”terminals, and tie the shield to chassis ground. Connect unbalanced sources with two conductor shielded cable connected to
“+” and “–”, with the shield connected to one of the chassis ground screws (7). See DA 216a Connection on page Manual-4.
2
Output terminals 1-16:
Balanced Outputs are provided for each of 16 channels. Connect two conductor shielded cable to “+”
and “–” terminals. Connect the shield to one of the chassis ground screws. For unbalanced use, do not connect “–” to chassis
ground…doing so results in improper operation. See the Outputs section on page Manual-4.
3
INPUT PAD switches:
In the MIC position (out), the gain is appropriate for a microphone Input (40 dB or 60 dB). In the LINE
position (in), the gain is line-level (0 dB or 20 dB). When this switch is in the LINE position, PHANTOM POWER for the
channel is disabled.
4
INPUT GAIN switches:
Changes the gain by 20 dB. That is, with mic Input, the INPUT GAIN switch sets the gain to 60 dB
(out) or 40 dB (in). With a line-level Input, it sets the gain to 20 dB (out) or 0 dB (in).
5
PHANTOM POWER switch:
When activated (in), 15 VDC Phantom Power appears at each mic-level Input and the PHAN-
TOM POWER LED illuminates. If an Input is selected for line-level, the Phantom Voltage is disabled for that channel, even
when the PHANTOM LED is lit.
6
POWER Input connector:
Use only a model RS 1 or other remote AC power supply approved by Rane. Consult the factory
for replacement or substitution. Never use a power supply with your DA 216a 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?
7
Chassis ground screws:
#6-32 screws are used for chassis grounding purposes. Attach the shields of the audio cables to these
points. See the Chassis Grounding note below.
