User manual RANE HC 6S

[. . . ] These Inputs may also be converted to balanced mono inputs by moving internal jumpers. 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. HC 6S CONNECTION When first connecting the HC 6S to other components, leave the power off. This gives you a chance to make mistakes and correct them without damage. [. . . ] When the yellow LED is lit, the HC 6S is ready to go.

RANE CORP. HC 6S BALANCED TIP = POSITIVE (+), RING = NEGATIVE (­), SLEEVE = SHIELD UNBALANCED LINE INPUTS: TIP = LEFT, RING = RIGHT, SLEEVE = GROUND This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesire d operation. ACN 001 345 482 4 1 2 3 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. 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). These are ¼" TRS (tip-ring-sleeve) Input jacks, each accepting both left and right channels. If you plug a regular TS (tip-sleeve) into this jack, you will only connect the left channel. To feed this input with an unbalanced mono signal, use a TRS plug and wire the tip and ring together. To build a cable that will combine separate left and right cables into a single ¼" TRS, follow the diagram below, connecting all shields. RCA connectors can be substituted for the ¼" connectors. To use balanced mono sources, set the internal jumpers as shown on page Manual-4. 3 Stereo Headphone OUTs allow any headphone with an impedance from 32 to 600 . (Lower and higher impedance headphones may be used; they just won't be very loud. ) 4 Universal Voltage Input: via a miniature IEC 60320 C6 appliance inlet. This mates with an IEC 60320 C5 line cord (USA domestic). The wide voltage range of this input allows it to be powered almost anywhere in the world.

Manual-3 OPERATING INSTRUCTIONS 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 a direct stereo IN, only this control affects the volume in the headset--the MASTER LEVEL is bypassed. [. . . ] 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 6S, use headphones of the same make and model. [. . . ]
