DO NOT OPEN
CAUTION
IMPORTANT SAFETY INSTRUCTIONS
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with a dry cloth.
7. Do not block any ventilation openings. Install in accordance with manufacturer’s instructions.
8. Do not install near any heat sources such as radiators, registers, stoves, or other apparatus (including ampliers) that produce heat.
9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding-type plug has two blades and a third grounding prong. e wide blade or third prong is provided for your safety. If the provided plug does not
t into your outlet, consult an electrician for replacement of the obsolete outlet.
10. Protect the power cord and plug from being walked on or pinched particularly at plugs, convenience receptacles, and the point where it exits from
the apparatus.
11. Only use attachments and accessories specied by Rane.
12. Use only with the cart, stand, tripod, bracket, or table specied by the manufacturer, or sold with the apparatus. When a cart is used, use caution
when moving the cart/apparatus combination to avoid injury from tip-over.
13. Unplug this apparatus during lightning storms or when unused for long periods of time.
14. Refer all servicing to qualied service personnel. Servicing is required when the apparatus has been damaged in any way, such as power supply
cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does
not operate normally, or has been dropped.
15. e plug on the power cord is the AC mains disconnect device and must remain readily operable. To completely disconnect this apparatus from
the AC mains, disconnect the power supply cord plug from the AC receptacle.
16. is apparatus shall be connected to a mains socket outlet with a protective earthing connection.
17. When permanently connected, an all-pole mains switch with a contact separation of at least 3 mm in each pole shall be incorporated in the electrical installation of the building.
18. If rackmounting, provide adequate ventilation. Equipment may be located above or below this apparatus, but some equipment (like large power
ampliers) may cause an unacceptable amount of hum or may generate too much heat and degrade the performance of this apparatus.
19. is apparatus may be installed in an industry standard equipment rack. Use screws through all mounting holes to provide the best support.
WARNING: To reduce the risk of re or electric shock, do not expose this apparatus to rain or moisture. Apparatus shall not be exposed to dripping
or splashing and no objects lled with liquids, such as vases, shall be placed on the apparatus.
NOTE: is equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. ese
limits are designed to provide reasonable protection against harmful interference in a residential installation. is equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the equipment o and on, the user is encouraged to try to correct the interference
by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit dierent from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
CAU TIO N: Changes or modications not expressly approved by Rane Corporation could void the user's authority to operate the equipment.
is Class B digital apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe B est conforme à la norme NMB-003 du Canada.
WARNING
To reduce the risk of electrical shock, do not open the unit. No user
serviceable parts inside. Refer servicing to qualied service personnel.
e symbols shown below are internationally accepted symbols that warn
of potential hazards with electrical products.
is symbol indicates that a dangerous voltage
constituting a risk of electric shock is present within
this unit.
is symbol indicates that there are important
operating and maintenance instructions in the

QUICK START
Shredded, this document makes excellent packing material. In
its present form, it makes interesting and useful reading. If you
run out of patience quickly, at least read this part to make sure
you don’t exterminate everything within a two mile radius by
doing something wrong.
First, be sure the POWER switch is off. Attach one or two
channels of Inputs and Outputs to the respective connectors on
the rear. is device uses low impedance balanced line drivers. Do
not connect the XLR “+” or “–” output pins to ground, as this may
cause the power supply to shut down. For unbalanced use, leave the
unused output pin (“+” or “–”) unterminated. OK, now you can
power up your sound system, volumes down, amp turned on last.
With the GATE THRESHOLD turned all the way down to
-80 dBu, COMPRESSOR THRESHOLD turned all the way
up to 20 dBu, COMPRESSOR RATIO turned all the way
down to 1, and the OUTPUT LEVEL control in the center at 0
dB, you have an expensive patch cord.
While sending a signal to the DC 22S, adjust the output
level of the previous device so the +4 dBu LED lights occasionally, but the OL LED does not light. If you are driving the ¼"
DC 22S
STEREO COMPRESSOR
INPUTS with a balanced signal (tip-ring-sleeve), set the Input
Gain switch to +4 dBu (in). When driving this input with an
unbalanced signal (tip-sleeve), set this switch to –10 dBv (out).
Regardless of the type of Input, you might need to set this switch
so the INPUT LEVEL LEDs light correctly.
Now increase the COMPRESSOR RATIO to something
useful, like 2:1 (with the control set at 2, the Ratio is 2:1; at 5, it
is 5:1.) Adjust the COMPRESSOR THRESHOLD to the point
you want the Compressor to kick in. e GAIN REDUCTION
meter reads the amount of signal compression.
If you want the quiet parts to be even quieter, increase the
GATE THRESHOLD so only higher levels make it through the
Gate.
Both Gates and Compressors will activate by the source
material applied to either channel if the LINK switch is on. is
is the preferred setting for stereo program material. e channel 1 controls set both channels to the same adjustments, as the
channel 2 controls go dormant and the LEDs extinguish. If
the LINK switch is off, then both channels are independently
controllable.
WEAR PARTS: is product contains no wear parts.
