Quick Start

With the power switch in the o (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 unbal­anced 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 dierent
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.

WEAR PARTS: is product contains no wear parts.

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 ickering 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.

1 Universal Voltage Input: via a miniature IEC 60320 C6 appliance inlet. is mates with an IEC 60320 C5 line cord (USA

domestic). Do not lift the ground connection!

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 dierent when hooking up balanced or unbalanced lines. e HC 4S is one smart animal.
