Section 1 - Introduction The Jensen JT-MS-8N2 provides 8 channels of extremely high quality 2 way microphone splitting with 48 Volt phantom power individually selectable on each channel. This functionality is provided in a compact 11.35"W x 4.75"H x 2.25"D package allowing 7 units (56 channels) to be mounted vertically on a 7U size rack panel (see Figure 2.4.1). -
Page 4: Section 2 - Installation
The schematic diagram shown in Figure 1 is representative of each of the eight channels of the JT-MS-8N2 Microphone Splitter. Reference designators for the other seven channels are determined as follows: Switch, transformer and plug reference designators correspond to the channel number, while resistor, capacitor and jack reference designators are formed by adding a digit representing the channel number ahead of the nominal part reference number. -

JT-MS-8N2. Stranded wire should be used if connections will be subjected to repeated movement or vibration, to prevent breakage. Under normal circumstances, the low side of the phantom power supply, 48C, is connected directly to the groundplane, GND, through the jumper at P9. -
Page 7: Mounting
Four 0.172" diameter mounting holes are provided along the bottom mounting flange and along the top edge of the JT-MS-8N2 for mounting the unit with the printed circuit board either parallel to or perpendicular to a bulkhead or wall. If the unit is mounted with the printed circuit board parallel to the bulkhead or wall, four right angle mounting brackets may be also used to attach the bottom flange to the wall for additional rigidity. -
