[. . . ] 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. . [. . . ] It is suggested that XLR cable connectors used with the HV-3D employ identical plating. (2) HIGH VOLTAGE MIC INPUTS "130V IN (1 - 8)" Four pin female XLR connector for use only with B&K (DPA) models 4003, 4004, 4009, and 4012 microphones. On HV-3D units without this option, a metal plate will cover the unused XLR holes. Connecting anything other than the above listed B&K (DPA) models to this connector may result in serious damage to microphone, the HV-3D unit, or both. It is suggested that XLR cable connectors used with the HV-3D employ identical plating. (3) LINE LEVEL OUTPUTS "OUT (1 - 8)" Conventional three pin male XLR connectors providing balanced, line level microphone output. The line level output is capable of driving 600 ohm loads and long, high capacitance cables. Outputs may be configured in an unbalanced configuration by either grounding one of the audio polarities (pin 2 or pin 3), or taking one audio polarity directly as an unbalanced signal. In the former configuration, the output is automatically increased by 6 dB. It is suggested that XLR cable connectors used with the HV-3D employ identical plating. (4) EARTH/AUDIO GROUND JUMPER A barrier terminal which ties earth ground to audio ground. If ground "hum" loops are experienced when using the HV-3D, removing this jumper may help. Using this jumper to lift ground, the integrity of the chassis/ earth ground connection is never compromised. Do not defeat the earth grounding pin on the AC plug. (5) 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 HV-3D 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 2 ch, use 5 x 20 mm, 400 mA, slow blow, 250 V Littelfuse 218 or equiv. , For 100-120 VAC mains 4 ch, use 5 x 20mm, 630 mA, slow blow, 250 V Littelfuse 218 or equiv. , For 100-120 VAC mains 8ch, use 5 x 20 mm, 1. 00 A, slow blow, 250 V Littelfuse 218 or equiv. , For 200-240 VAC mains 2 ch, use 5 x 20 mm, 200 mA, slow blow, 250 V Littelfuse 218 or equiv. , For 200-240 VAC mains 4 ch, use 5 x 20 mm, 315 mA, slow blow, 250 V Littelfuse 218 or equiv. [. . . ] The HV-3D micamp circuits maintain nearperfectly flat, inter-channel matched frequency response and less than 1/4 degree of interchannel phase error -- a perfect compliment to a factory-matched pair of DPA microphones.
