[. . . ] The material contained in this manual consists of information that is property of Millennia Media, Inc. and is intended solely for use by the purchasers of the equipment described in this manual. expressly prohibits the duplication of any portion of this manual or the use thereof for any purpose other than the operation and/or maintenance of the equipment described in this manual without the express written permission of Millennia Media, Inc. . Under copyright laws, this manual may not be duplicated in whole or in part without the written consent of Millennia Media, Inc. . [. . . ] In the USA, the NSEQ-2 is shipped with the voltage selection block set to 100-120 VAC. At this voltage setting, a pair of 1 amp 5 x 20 mm slow blow fuses have been factory installed. If you change the voltage selection block to 200-240 VAC usage, be sure to change both fuses to 500 milliamp (0. 4 amp) slow blow types. The NSEQ-2 enclosure measures 19" wide x 3. 5" high x 12. 5" deep and is designed for mounting into a standard 2U, 19" equipment rack. If the NSEQ-2 is mounted in a road case or other rack which is prone to strong vibration or shock, it is recommended that the rear of the NSEQ-2 be supported or otherwise reinforced to withstand such conditions. To assure proper air circulation and operation, leave at least one rack space open above and below the NSEQ-2. For high quality operation, and for your own safety and the safety of others, do not defeat the purpose of the earth grounding pin on the A/C power cord! NSEQ-2 4 NSEQ-2 REAR PANEL (1) INPUTS "In 1 (Left), In 2 (Right)" Conventional 3-pin female XLR input jacks for all balanced or unbalanced line level signals. Input impedance is greater than 10k ohms when "10 dB" gain range switch is engaged (+/10dB), greater than 40k ohms when gain range switch is disengaged (+/- 20dB), and greater than 100k ohms when optional balanced inputs are installed. Standard NSEQ-2 line input is unbalanced using pin 1 as chassis ground, pin two as signal, and pin 3 tied to audio ground. (2) OUTPUTS "Out 1 (Left), Out 2 (Right)" Conventional 3-pin male XLR output jacks. Pin 1 is chassis ground, pin 2 is signal, and pin 3 is tied to audio ground. Vacuum tube output impedance is 150 ohms. (3) EARTH/AUDIO GROUND JUMPER A barrier terminal which ties earth ground to audio ground. If ground "hum" loops are experienced when using the NSEQ-2, removing this jumper may help. Using this jumper, the integrity of the chassis/earth ground connection is never compromised. (4) AC VOLTAGE MAINS SELECTION "100-120" or "200-240" A power entry module with a removable fuse holder block. This fuse holder block is selectable for 100 to 120 Volt or 200 to 240 Volt worldwide mains powering. The fuse block contains two fuses -- one fuse is in series with the hot power line while the other fuse is in series with the neutral power line. To change the mains voltage selection, remove IEC power connector and assure that the NSEQ-2 is not connected to mains power. With a non-conductive tool, gently pry the fuse block away from the power entry module. Slide out the internal PC Board, turn it over, and reinsert the PCB so that the desired AC mains voltage appears in the viewing window. Double check that the fuses installed correspond to the AC mains voltage range which appears in the viewing window. FUSES: For 100-120 VAC mains, use 5x20mm, 1A, slow blow, 250V Littelfuse 239 or equivalent. , For 200-240 VAC mains, use 5x20mm, 500 mA, slow blow, 250V Littelfuse 239 or equivalent. , (5) POWER ENTRY "IEC Power Receptacle" An IEC-type AC line-power receptacle for use with removable cords.
