HEADPHONES (PHONES)
The PHONES jack accepts 2-conductor (mono) or
3-conductor (stereo) headphones with an impedance of
4Ω to 32Ω (standard is 8Ω) and a 6.3 mm (1/4") diameter
plug.
While the headphones are plugged in, the audio line for
the internal speaker (or an optional external speaker) is
muted and the audio is heard through the headphones.
The following optional headphones can be used with this
transceiver:
• HS-5 (monaural) • HS-6 (monaural)
Note:
◆ Headphones with a higher impedance also have a higher volume
level.
◆ Refer to "BASIC OPERATIONS" for details of configuration for the
mixing balance to the headphones output and the left and right
reverse. {page 4-23}
