External aural subcarrier input. This input is selectable from the front panel or (optional) remote
control. The input level (at 6.0MHz for PAL I units) should be +25 to +45dBmV (measured into
75
Ω ). The OTM-4000 I has limiter circuitry to keep the aural carrier constant when the external
subcarrier signal level is within the above range.
AC LINE POWER INPUT
The OTM-4000 I may be powered by 90 to 240 VAC and 47-63 HZ and it draws about 24
Watts.
5.) MISCELLANEOUS
A) When mounting the OTM-4000 in an equipment rack, it is best to leave a blank space above and
below the unit to allow for adequate flow of cooling air.
B.) This unit is equipped with a 0.5A slo-blo fuse, which is located at the IEC power input module at
the rear panel. For continued safety and to maintain proper performance of the unit, please replace
only with an equivalent fuse.
