QUICK START
Okay, you’re in a hurry. Well this section’s just for you. It explains enough of the HC 6’s workings to keep you out of trouble. It
allows operation without reading the whole manual. Please read at least this section to ensure reasonable operation of the unit.
The HC 6 operates from either a common stereo or mono source, or from individual stereo sources. For a common stereo source,
plug the left and right input plugs into the respective MASTER INPUTS jacks. The Inputs accept balanced or unbalanced sources.
Just plug them in. This source is now routed to each of the six input Channels to drive all Outputs.
For a single mono source feeding all headphones, connect it to one of the MASTER INPUT jacks and engage the STEREO/
MONO switch. Set the overall input level with the MASTER CONTROL, and use the CHANNEL LEVEL controls for individual
headphone levels.
Use the separate stereo IN jacks when driving a pair of headphones with different program material than what is on the MASTER INPUTS. Connecting a plug into these jacks automatically disconnects that Channel from the Master Input program material.
These Inputs may also be converted to balanced mono inputs by moving internal jumpers. See page Manual-4.
Never connect anything except a Rane power supply to the thing that looks like a telephone jack on the rear of the unit. This
is an AC input and requires special attention if you do not have a power supply exactly like the one originally packed with your unit.
See the full explanation of the power supply requirements elsewhere in this manual.
HC 6 CONNECTION
When first connecting the HC 6 to other components, leave
the power supply for last. This gives you a chance to make mistakes and correct them without damage.
1. With the power switch in the off position, plug the power
supply line cord into the rear panel. Locate the power supply
away from the HC 6 and other hum sensitive equipment.
2. Plug the outputs from a mono or stereo source into the MASTER INPUTS. For unbalanced systems use a standard ¼" TS
cable. For balanced operation, use a stereo ¼" TRS connector
with pin 2 (+) wired to the Tip; pin 3 (–) wired to the Ring;
and pin 1 (ground) wired to the Sleeve. Please consult the
RaneNote, “Sound System Interconnection” (enclosed) for
additional wiring arrangements.
WEAR PARTS: This product contains no wear parts.
3. When rack mounting the HC 6, you may wish to permanently wire the rear headphone Outputs to remote jack locations,
such as in walls of a studio or other rooms. Use the front panel
Outputs for local or control room monitoring.
4. You might also consider wiring the six direct stereo INs
permanently to a patch bay or monitor mixer, but only if you
do not plan to use the MASTER INPUTS as well. Whenever
a plug is inserted into any individual stereo IN, the MASTER INPUTS are bypassed for that particular channel. So
for maximum flexibility, we suggest that only the MASTER
INPUTs be permanently wired and that the direct stereo INs
be patched as necessary.

1 Front panel PHONES Output jacks are in parallel with the rear panel stereo Output jacks. Use them to monitor any of the six
Channels for level or mix adjustments, or for easy access when the HC 6 is rack mounted. Plugging into these front jacks does not
disengage the rear Outputs.
2 SIGnal present indicators light (green) with any input signal above -20 dBu. See OPERATING INSTRUCTIONS (on page
Manual-4) for complete details.
3 Individual LEVEL controls set the volume for each set of headphones, regardless of whether they are driven from the MASTER
INPUTS or from the direct stereo INs. When using the front and rear panel headphone jacks together, this control varies the level
of each headphone simultaneously.
4 MONO / STEREO switch converts the MASTER INPUTS from stereo to mono so that a single input cable drives both sides of
the headphones.
5 MASTER LEVEL sets the volume simultaneously to all headphones driven from the MASTER INPUTS. This does not alter the
volume on any headphones driven from the direct stereo INs.
6 POWER switch. Your basic, straightforward power switch. When the yellow LED is lit, the HC 6 is ready to go.

1 MASTER INPUTS are automatic balanced/unbalanced Inputs, which accept either a ¼" TRS (tip-ring-sleeve) plug for balanced
operation, or a ¼" TS (tip-sleeve) plug for mono operation. You do nothing different when hooking up balanced or unbalanced
lines. The HC 6 is one smart dude. He knows what you are doing so you better watch out.
2 Direct Stereo INs allow each stage to be driven separately, from any source. Whenever a plug is inserted into one of these Inputs,
the MASTER INPUTS are disconnected from that stage (and only that stage). I told you the dude be smart!
These are ¼" TRS (tip-ring-sleeve) Input jacks, each accepting both left and right channels. If you plug a regular TS (tipsleeve) into this jack, you will only connect the left channel. If you want to feed this input with an unbalanced mono signal, use
a TRS plug and wire the tip and ring together. When using balanced mono sources, set the internal jumpers as shown on page
Manual-4.
To build a cable that will transfer separate left and right cables to a single ¼" TRS, follow the diagram below, connecting all
shields. RCA connectors can be substituted for the ¼" connectors.
3 Stereo Headphone OUTs allow any headphone with an impedance from 32 to 600 Ω. Then kick back and enjoy. (Lower and
higher impedance headphones may be used; they just won’t be very loud.
4 Remote POWER supply input. The unit is supplied from the factory with a Model RS 1 remote power supply suitable for connection to this input jack. The power requirements of the unit call for an 18 volt AC center-tapped transformer only. This is not
a telephone jack. Never use a power supply with your unit other than the one supplied or a replacement approved by Rane Corporation.
Using any other type of supply may damage the unit and void the warranty.
5 Chassis ground point. A #6-32 screw used for chassis grounding purposes. See the CHASSIS GROUNDING note below.

CHASSIS GROUNDING
Units with outboard power supplies do not ground the
chassis through the line cord. Make sure that these units are
grounded either to another chassis which is earth grounded,
or directly to the grounding screw on an AC outlet cover by
means of a wire connected to the chassis grounding screw.

OPERATING INSTRUCTIONS
PLUG IN
Once connected as described in the HC 6 CONNECTION
section on page Manual-1, the HC 6 is ready to drive any impedance headphones from 32 to 600 Ω. Plug your headphones into
any of the six Outputs on the front or rear.
MASTER STEREO INPUTS
Apply a source program to the MASTER INPUTS and turn
up the MASTER LEVEL until the green signal-present LEDs
light up. Further adjustment of this control raises or lowers the
volume level in all headphones simultaneously, i.e., all those being driven from the MASTER INPUTS. The MASTER LEVEL
does not affect channels driven from the direct stereo INs.
INDIVIDUAL LEVEL CONTROLS
These adjust the level in each set of headphones to the desired
loudness. When using the direct stereo IN, only this control
affects the volume in the headset—the MASTER LEVEL is
bypassed.
DIRECT STEREO INPUTS
These allow completely independent operation of up to six
different stereo programs. These Inputs are stereo only, and
wired to accept unbalanced signals, using the tip=left, ring=right
convention. Unbalanced mono sources require using a stereo ¼"
TRS plug and shorting the tip and ring together.
When using balanced mono sources, internal jumpers must
be moved as in the diagram below. Jumpers are wired at the
factory for stereo. Jumpers must be moved for balanced mono
operation. Each jack is jumpered separate, so any combination of
input types is possible within a single HC 6.
Any Channel not directly driven is automatically driven from
the MASTER INPUTS.
PHONES
STEREO
INPUT
SIGNAL-PRESENT LEDS
These light up with any signal input above -20 dBu. They
are located in the signal path after the MASTER INPUTS and
before the individual LEVEL controls. This means that adjusting
the MASTER LEVEL affects the SIG LEDs, while adjusting the
individual LEVEL controls does not. When using a direct stereo
IN, the LED responds to that Input only. This means these
indicators aid in quickly identifying which stages are driven by
the MASTER INPUTS and which by the direct stereo INs:
Simply turn the MASTER LEVEL up and down and observe
which LEDs respond. These are the Channels being driven by
the MASTER INPUTS.
STEREO/MONO SWITCH
This serves the basic function of allowing both Left and
Right channels of all headphones to be driven from a mono
MASTER INPUT. In some instances a stereo program can be
confusing for live monitoring purposes, due to extreme separation and the increased difficulty in perceiving several different
volume levels. Using the MONO / STEREO switch converts the
system to mono operation to better suit these particular monitoring needs.
FRONT PANEL OUTPUT JACKS
These jacks parallel the rear OUTs, providing easy access
patching into any Channel for cueing or additional monitoring.
When using more than six sets of headphones at once, keep two
things in mind:
1. There are still only six LEVEL controls. Additional headsets
must double up with those already in use. To avoid intolerable
volume differences to two listeners on the same channel of the
HC 6, use headphones of the same make and model.
2. The HC 6 has limited power output. The more headphones
you connect to it, the less power there is available to each set,
and the more strain on the HC 6. Blasting 10 or 12 sets of low
impedance headphones is asking too much from the HC 6. To
lessen the power drain from the HC 6, use only high impedance (100 Ω or greater) headphones when paralleling.
Figure 2. Moving internal jumpers near each Input jack convert stereo
unbalanced inputs to mono balanced inputs.
