Rear Panel Description 100-240 V 50/60 Hz 7 WATTS 5 COMMERCIAL AUDIO EQUIPMENT 24TJ R 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 undesired operation. ME 30S MADE IN U.S.A. RANE CORP. ACN 001 345 482 WIRING TIP / PIN 2 = POSITIVE RING / PIN 3 = NEGATIVE SLEEVE = SIGNAL GROUND PIN 1 = CHASSIS GROUND OUTPUT INPUT 43 21 1 XLR INPUT jack: Accommodates balanced signals. Rane adheres to the international and U.S. standard for balanced pin configurations: Pin 1 is chassis ground (neutral), pin 2 is hot (positive), and pin 3 is signal return (negative). Choose between this and the ¼" TRS Input jack-use only one-they do not sum. 2 ¼" TRS INPUT jack: This TRS (Tip-Ring-Sleeve) ¼" jack accommodates either balanced or unbalanced signals. For an unbalanced signal use a mono ¼" plug (single conductor with shield). For a balanced signal use microphone cable (two conductor with shield) with a TRS ¼" plug. Choose between this and the XLR Input jack-use only one-they do not sum. Refer to the included RaneNote, "Sound System Interconnection" for unbalanced wiring. 3 ¼" TRS OUTPUT jack: This TRS (tip-ring-sleeve) ¼" balanced jack is compatible with either balanced or unbalanced systems. For balanced systems, use a microphone cable wired with pin 1 is chassis ground (neutral), pin 2 is hot (positive), and pin 3 is signal return (negative). Refer to the RaneNote, "Sound System Interconnection" for unbalanced wiring. 4 XLR OUTPUT jack: This balanced output is wired per AES standards of pin 2 "hot", as described above in 1. 5 Universal Voltage Input: via a miniature IEC 60320 C6 appliance inlet. This mates with an IEC 60320 C5 line cord (USA domestic). Do not lift the ground connection! ME 30S Connection INPUTS Both XLR and ¼" TRS Inputs are wired in parallel and are actively balanced. Each works equally well. Choose strictly from a required hardware point-of-view, there will be no performance trade-offs. The wiring convention adheres to American, British and International standards of pin 2 or tip being hot, pin 3 or ring being return, and pin 1 or sleeve being shield. Unbalanced operation involves using only pin 2 or tip as signal, and pin 1 or sleeve as shield or ground. It is not necessary to short any inputs to ground-it doesn't hurt, it's just not necessary. Use pin 1, or the shell, for shield ground. OUTPUTS The Outputs mimic the Inputs. Balanced output requires using pin 2 or tip, and pin 3 or ring for the signal. It does not require pin 1 or shield. The signal exists differentially between the two balanced leads; ground is not involved. For hum-free systems ground is used only for shielding. EXPANDING Expanding and/or daisychaining the Inputs and Outputs normally us0es the ¼" jacks. Three parallel Input connectors allows driving a second signal processor or amplifier without special cabling. SIGNAL LEVELS Signal levels from -10 dBV to +4 dBu are considered normal and within range (at least 20 dB of headroom exists above these levels). Do not directly connect microphones into the ME 30S. These require an external mic preamp. Manual-
