Rane HC 4 2003 version - Manual (Page 4)

Manual-
1 STEREO/MONO switch converts the INPUTS from stereo to mono so that a single input cable drives both sides of the head-
phones. In some instances a STEREO program may be confusing for live monitoring purposes, and switching to MONO im-
proves intelligibility by summing the Left and Right signals.
2 PHONES jacks accept standard ¼" 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. The red OL indicators light when the
input signal exceeds the HC 4’s output capability (3 dB below maximum). Occasional flickering is acceptable, but a steady glow
recommends turning the LEVEL control down.The 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 4 is ready to go.
1 Remote POWER supply input The unit is supplied from the factory with a Model RS 1 remote power supply suitable for con-
nection 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.
2 INPUT jacks These are automatic balanced/unbalanced Inputs, which accept either a ¼" TRS (Tip-Ring-Sleeve) plug for bal-
anced operation, or a ¼" TS (Tip-Sleeve) plug for unbalanced operation. A balanced line is best when connecting a cable over 10
feet in length. You do nothing different when hooking up balanced or unbalanced lines. The HC 4 is one smart animal.
