764 Digital Audio Monitor User Manual
Figure 7: The headphone output (schematic)
By factory default, the headphone output automatically follows the
phase display; that is, it contains the audio programs decoded from the
two channels that you are monitoring with the Lissajous pattern and
correlation meter. You may also choose to listen to any two of the
input channels, independent of the phase display choices; for
instructions, refer to Selecting Headphone Channels on page 48.
Supplying Power
You can operate the 764 on any AC power supply that provides 90 to
250 V at 50 to 60 Hz. If the power cord supplied with your instrument
is incorrect for your local AC supply, please contact your nearest
Tektronix representative or field office.
WARNING. Line voltage will be present in the instrument whenever
power is supplied even if the POWER switch is set to STANDBY
.
Always disconnect the power cord before removing the instrument
from its cabinet.
