DA 216 REAR PANEL
IMPORTANT NOTE
CHASSIS GROUNDING
The DA 216 is supplied with an external power supply (the RS 1). This power supply does not ground the unit. On
the rear chassis is provided a 6-32 screw 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, (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 using the nearest chassis grounding terminal above the screw terminals. Connect unbalanced
sources with two conductor shielded cable connected to “+” and “–”, with the shield connected to chassis ground. Refer to
the Sound System Interconnection section later in this manual.
2. OUTPUT terminals. Balanced OUTPUTS are provided for each channel. Connect two conductor shielded cable to “+” and
“–” terminals. Tie the shield to ground, or leave open—your choice. For unbalanced use, do not tie “–” to GND. Doing so
results in improper operation. To obtain a 1-in-32-out single-ended distribution amp, use the “+” and GND for the “pri-
mary” output and connect the “–” and GND for the “secondary” output. (Note: The “secondary” outputs will be inverted.
If driving a balanced input circuit, swap the “+” for “–” terminals to invert the signal for correct polarity.)
3. INPUT PAD switch. In the 0 dB (out) position, the respective input stage is set for microphone input levels. In the -40 dB
(in) position, line level signals are accepted and Phantom Power for this input is disabled if activated.
4. GAIN. The gain switches change the gain by 20 dB and are used along with the MASTER LEVELS to trim input gain for
optimum dynamic range. See OPERATING INSTRUCTIONS on page Manual-4.
5. PHANTOM POWER switch. When activated (in), 15 VDC Phantom Power appears at each 0 dB PAD selected INPUT,
and the PHANTOM POWER LED illuminates.
6. POWER input connector. Use only a model RS 1, RAP 10, or other remote AC power supply approved by Rane. The
DA 216 is supplied with a remote power supply suitable for connection to this input jack. Consult the factory for replace-
ment or substitution.
7. Chassis ground points. 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.
