IMPORTANT NOTE
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.
Figure 1. Dual Mono to Stereo TRS Wye Cable.
See
ባ Above, Direct Stereo INPUTS.
ቢ MASTER INPUTS are automatic balanced/unbalanced Inputs, which accept either a stereo ¼" plug for balanced operation,
or a mono ¼" 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.
ባ Direct stereo INPUTS 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 mono
TS (tip-sleeve) 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 please consult the factory for
the required modification. Hint: this can be accomplished by moving theinternal jumpers by the input jacks as shown on the
assembly diagram.
To build a cable that will transfer separate left and right cables to a single ¼" TRS, follow the diagram below, connect-
ing all shields. RCA connectors can be substituted for the ¼" connectors.
ቤ Stereo headphone OUTPUTS allow any headphone with an impedance from 32 to 600 ohms. Then kick back and enjoy.
(Lower and higher impedance headphones may be used; they just won’t be very loud. Refer to RaneNote 100, “Understand-
ing Headphone Power Requirements” for headphone loudness listings.)
ብ 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.
ቦ Chassis ground point. A #6-32 screw used for chassis grounding purposes. See the CHASSIS GROUNDING note below.
