RISK OF ELECTRIC SHOCK
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 TION: 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.

Quick Start
With the power switch in the off (out) position, plug the
power cord into an appropriate AC power source.
Begin with all LEVEL controls counterclockwise at “0.”
Connect the output from any stereo source such as a mixer,
CD or MP 3 player, and plug the left and right inputs into the
respective INPUT jacks. e Inputs accept balanced or unbal-
anced sources. Just plug them in. is source is now routed to
each of the four Outputs.
See the Sound System Interconnection RaneNote for information on proper cable wiring between devices that have different
connector types and grounding schemes.
For a single mono source feeding all headphones, connect
it to either one of the INPUT jacks and push the MONO /
STEREO SOURCE switch in. Set the LEVEL controls for
individual headphone levels.

1 STEREO / MONO switch converts the INPUTS from stereo to mono so that a single input cable drives both sides of the
headphones. In some instances a STEREO program may be confusing for live monitoring purposes, and switching to MONO
improves intelligibility by summing the Left and Right signals.
2 PHONES jacks accept standard ¼" and 3.5mm TRS (tip-ring-sleeve) stereo headphone plugs.
3 LEVEL controls adjust the volume for each set of headphones as they are driven from the rear INPUTS. It’s always a good idea
to keep this control turned down before plugging in a pair of phones, then turn it up slowly. e red OL indicators light when the
input signal exceeds the HC 4S’s output capability (3 dB below maximum). Occasional flickering is acceptable, but a steady glow
recommends turning the LEVEL control down.e overload point automatically varies with the headphones used.
4 POWER switch is your basic, straightforward power switch. When the yellow indicator is lit, the HC 4S is ready to go.

2 INPUTS are automatic balanced or unbalanced, accepting either a ¼" TRS (Tip-Ring-Sleeve) plug for balanced operation, or
a ¼" TS (Tip-Sleeve) plug for unbalanced operation. A balanced line is best when connecting a cable over 10 feet (3 meters) in
length. You do nothing different when hooking up balanced or unbalanced lines. e HC 4S is one smart animal.
